Salt 2018.3.0 Release Notes - Codename Oxygen

Warning

If you are using Jinja to dump lists or dictionaries in your SLS files, this will now cause errors in Python 2 since Jinja does not produce YAML-compatible output when strings in the data structures contain unicode types. The dictionary must be passed through a Jinja filter to produce YAML-compatible strings.

The below is an example of invalid SLS:

/etc/foo.conf:
  file.mangaged:
    - source: salt://foo.conf
    - template: jinja
    - defaults: {{ mydict }}

To make it valid, use either one of Salt's own json or yaml filters:

/etc/foo.conf:
  file.mangaged:
    - source: salt://foo.conf
    - template: jinja
    - defaults: {{ mydict | json }}

Unicode/Python 3 Compatibility Improvements

This release fixes a number of nagging issues with Unicode strings in Salt under Python 2 (ex. 'ascii' codec can't decode byte 0xd0). For best results, use a UTF-8 locale (such as by setting the LANG environment variable to one which supports UTF-8. For example en_US.UTF-8, de_DE.UTF-8, ru_RU.UTF-8, C.UTF-8).

Additionally, a number of Python 3 compatibility fixes have been made, many of them having to do with file I/O and str/bytes mismatches.

We continue to work toward improving both Unicode and Python 3 compatibility and welcome any feedback.

Lots of Docker Improvements

Much Improved Support for Docker Networking

The REMOVED DURRING MODULE MIGRATION state has undergone a full rewrite, which includes the following improvements:

Full API Support for Network Management

The improvements made to input handling in the docker_container.running state for 2017.7.0 have now been expanded to docker_network.present. This brings with it full support for all tunable configuration arguments.

Custom Subnets

Custom subnets can now be configured. Both IPv4 and mixed IPv4/IPv6 networks are supported. See REMOVED DURRING MODULE MIGRATION for more information.

Network Configuration in docker_container.running States

A long-requested feature has finally been added! It is now possible to configure static IPv4/IPv6 addresses, as well as links and labels. See REMOVDE DURRING MODULE MIGRATION for more information.

Note

While the containers argument to docker_network.present will continue to be supported, it will no longer be the recommended way of ensuring that a container is attached to a network.

Improved Handling of Images from Custom Registries

Rather than attempting to parse the tag from the passed image name, Salt will now resolve that tag down to an image ID and use that ID instead.

Important

Due to this change, there are some backward-incompatible changes to image management. See below for a full list of these changes.

Backward-incompatible Changes to Docker Image Management

Passing image names to the following functions must now be done using separate repository and tag arguments:

  • docker.build

  • docker.commit

  • docker.import

  • docker.load

  • docker.tag

  • docker.sls_build

Additionally, the tag argument must now be explicitly passed to the docker_image.present state, unless the image is being pulled from a docker registry.

State and Execution Module Support for docker run Functionality

The docker_container.running state is good for containers which run services, but it is not as useful for cases in which the container only needs to run once. The start argument to docker_container.running can be set to False to prevent the container from being started again on a subsequent run, but for many use cases this is not sufficient. Therefore, the docker.run_container remote-execution function was added. When used on the Salt CLI, it will return information about the container, such as its name, ID, exit code, and any output it produces.

State support has also been added via the docker_container.run state. This state is modeled after the cmd.run state, and includes arguments like onlyif, unless, and creates to control whether or not the container is run.

Full API Support for docker.logs

This function now supports all of the functions that its Docker API counterpart does, allowing you to do things like include timestamps, and also suppress stdout/stderr, etc. in the return.

start Argument Added to docker.create Function

This removes the need to run docker.start separately when creating containers on the Salt CLI.

salt myminion docker.create image=foo/bar:baz command=/path/to/command start=True

Use SaltSSH Minions like regular Master-Minions

The Master process can now also call SSH minions as if they were connected to the master using ZeroMQ. By setting enable_ssh_minions: True in the master config file, the master will create a Salt SSH client process which connects to the minion and returns the output for the salt CLI to use like a regular minion. This can be used anywhere the LocalClient is used.

Exceptions Raised for Authentication/Authorization Errors

When sending publish commands via master.py and masterapi.py and an authorization or authentication problem is encountered, Salt will now raise the appropriate exceptions instead of returning an empty string: ''.

The reasoning behind this change is to make it easier to debug various scenarios surrounding authentication and authorization issues more effectively.

Comparison Operators in Package Installation

Salt now supports using comparison operators (e.g. >=1.2.3) when installing packages on minions which use yum/dnf or apt. This is supported both in the pkg.installed state and in the pkg.install remote execution function.

Master Tops Changes

When both Master Tops and a Top File produce SLS matches for a given minion, the matches were being merged in an unpredictable manner which did not preserve ordering. This has been changed. The top file matches now execute in the expected order, followed by any master tops matches that are not matched via a top file.

To make master tops matches execute first, followed by top file matches, set the new master_tops_first minion config option to True.

Several Jinja Filters Renamed

The following Jinja filters (originally added in 2017.7.0) have been renamed due to the fact that they were inaccurately named when initially added. The original names will be supported until the 3000 release of Salt.

  • rand_str renamed to random_hash

  • jinja_decode_dict renamed to jinja_encode_dict

  • jinja_decode_list renamed to jinja_encode_list

Return Codes for Runner/Wheel Functions

When using orchestration, runner and wheel functions used to report a True result if the function ran to completion without raising an exception. It is now possible to set a return code in the __context__ dictionary, allowing runner and wheel functions to report that they failed. Here's some example pseudocode:

def myrunner():
    ...
    # do stuff
    ...
    if some_error_condition:
        __context__["retcode"] = 1
    return result

Variable Update Intervals for Fileserver Backends

Prior to this release, fileservers would be updated as part of a dedicated "maintenance" process, in which various routine maintenance tasks were performed. This tied the update interval to the loop_interval config option, and also forced all fileservers to update at the same interval.

2018.3.0 adds the following configuration options for the various fileserver backends:

These allow for update intervals to be set for each individual backend. The default value for each of these is 60 seconds.

In addition, for GitFS it is also possible to apply intervals to individual remotes. See here for examples.

Note

git_pillar does not yet support variable update intervals, this is targeted for the next feature release (2019.2.0).

LDAP via External Authentication Changes

In this release of Salt, if LDAP Bind Credentials are supplied, then these credentials will be used for all LDAP access except the first authentication when a job is submitted. The first authentication will use the user's credentials as passed on the CLI. This behavior is to accommodate certain two-factor authentication schemes where the authentication token can only be used once.

In previous releases the bind credentials would only be used to determine the LDAP user's existence and group membership. The user's LDAP credentials were used from then on.

Stormpath External Authentication Removed

Per Stormpath's announcement, their API will be shutting down on 8/17/2017 at noon PST so the Stormpath external authentication module has been removed.

https://stormpath.com/oktaplusstormpath

New (Proxy) Minion Configuration Options

To be able to connect the Minion to the Master using a certain source IP address or port, the following options have been added:

environment config option renamed to saltenv

The environment config option predates referring to a salt fileserver environment as a saltenv. To pin a minion to a single environment for running states, one would use environment, but overriding that environment would be done with the saltenv argument. For consistency, environment is now simply referred to as saltenv. There are no plans to deprecate or remove environment, if used it will log a warning and its value will be used as saltenv.

lock_saltenv config option added

If set to True, this option will prevent a minion from allowing the saltenv argument to override the value set in saltenv when running states.

Failed Minions for State/Function Orchestration Jobs Added to Changes Dictionary

For orchestration jobs which run states (or run remote execution functions and also use a fail function to indicate success or failure), minions which have False results were previously included as a formatted string in the comment field of the return for that orchestration job. This made the failed returns difficult to parse programatically. The failed returns in these cases are now included in the changes dictionary, making for much easier parsing.

Grains

  • fc_wwn - Show all fibre channel world wide port names for a host, must be enabled with fibre_channel_grains

  • iscsi_iqn - Show the iSCSI IQN name for a host

  • swap_total - Show the configured swap_total for Linux, *BSD, OS X and Solaris/SunOS

  • virtual:

    • identifies reports KVM and VMM hypervisors when running an OpenBSD guest

    • for detecting Solaris Logical Domains (LDOMs) running on T-Series SPARC hardware. The virtual_subtype grain is populated as a list of domain roles.

Salt Minion Auto-discovery

Using auto-discovery, the Salt Minion now no longer needs to be configured against a specific DNS name or IP address of a Master.

For this feature Salt Master now requires port 4520 for UDP broadcast packets to be opened and the Salt Minion be able to send UDP packets to the same port.

Configuration

By default, automatic discovery is disabled.

Warning

Due to the current limitations that will be changing in a future release, before you turn on auto-discovery, make sure your network is secured and trusted.

Auto-discovery is configured on Master and Minion. Both of them are configured via the discovery option as follows:

Master configuration

To use the default configuration, which accepts any minion, simply set discovery to True:

discovery: true

A sub-option called mapping allows auto-discovery to help find the proper Master. The mapping contains an arbitrary set of key/value pairs, which the Minion configuration can target. By default, no mappings are set.

Example:

discovery:
  mapping:
    description: SES 5.0
    node: 1

It is also possible to change the port used from the default of 4520, by setting a port option under the Master's discovery configuration:

discovery:
  port: 4567

Note

When using a port number other than the default, the Minion's discovery configuration must also have a port specified, otherwise the Minion will still attempt to contact the Master on port 4520.

Minion configuration

In addition to the mapping and port options, the following additional options are available to Minions:

  • attempts - This option specifies how many broadcast requests should be sent to the network, waiting for any Master response. Each attempt takes a couple of seconds, so raising this value may result in a slower Minion startup. Note that, on a properly-configured network, autodiscovery should succeed on the first attempt. By default, this value is set to 3.

  • match - This option can be set to either all or any, and it determines how the values configured in mapping are matched. If set to all, then all of the key/value pairs in the Minion's mapping must match a given Master. If set to any (the default), then any match to a key/value mapping will constitute a match.

  • pause - The interval in seconds between attempts (default: 5).

  • fibre_channel_grains - Enables the fc_wwn grain. (Default: False)

  • iscsi_grains - Enables the iscsi_iqn grain. (Default: False)

Connection to a type instead of DNS

By now each Minion was connecting to a Master by DNS or IP address. From now on it is possible also to connect to a _type_ of a Master. For example, in a network there are three different Masters, each corresponds for a particular niche or environment or specific role etc. The Minion is supposed to connect only to one of those Masters that is described appropriately.

To achieve such an effect, each /etc/salt/master configuration should have a discovery option, which should have a mapping element with arbitrary key/value pairs. The same configuration should be on the Minion, so then when mapping matches, Minion recognises Master as its connection target.

Example for Master configuration (/etc/salt/master):

discovery:
  mapping:
    description: SES 5.0
    node: 1

The example above describes a system that is running a particular product, where description is an arbitrary key and SES 5.0 is just a string. In order to match exactly this Master, the following configuration at Minion should be present:

discovery:
  match: all  # Can be "all" or "any"
  mapping:
    description: SES 5.0
    node: 1

Notice match criteria is set to all. This would mean that from all found Masters select only that, which description is set to SES 5.0 _and_ node is set to 1. All other Masters will be ignored.

Limitations

This feature has a couple of _temporary_ limitations that are subject to change in the future:

  • Only one Master on the network is supported. Currently the Minion cannot select which Master out of few the same to choose. This will change to choosing the Master that is least loaded.

  • Minions will accept _any_ master that matches connection criteria without any particular security applied (priv/pub key check, signature, fingerprint etc). That implies that administrator is expected to know his network and make sure it is clean.

New Modules

  • salt.modules.purefa

New NaCl Renderer

A new renderer has been added for encrypted data.

New support for Cisco UCS Chassis

The salt proxy minion now allows for control of Cisco USC chassis. See the cimc modules for details.

New support for Cassandra v3

The cassandra_cql module now supports Cassandra v3 which has changed its internal schema to define keyspaces and columns.

New salt-ssh roster

A new roster has been added that allows users to pull in a list of hosts for salt-ssh targeting from a ~/.ssh configuration. For full details, please see the sshconfig roster.

New GitFS Features

Two new features which affect how GitFS maps branches/tags to fileserver environments (i.e. saltenvs) have been added:

  1. It is now possible to completely turn off Salt's default mapping logic (aside from the mapping of the base saltenv). This can be triggered using the new gitfs_disable_saltenv_mapping config option.

    Note

    When this is disabled, only the base saltenv and any configured using per-saltenv configuration parameters will be available.

  2. The types of refs which Salt will use as saltenvs can now be controlled. In previous releases, branches and tags were both mapped as environments, and individual commit SHAs could be specified as saltenvs in states (and when caching files using cp.cache_file). Using the new gitfs_ref_types config option, the types of refs which are used as saltenvs can be restricted. This makes it possible to ignore all tags and use branches only, and also to keep SHAs from being made available as saltenvs.

Additional output modes

The state_output parameter now supports full_id, changes_id and terse_id. Just like mixed_id, these use the state ID as name in the highstate output. For more information on these output modes, see the docs for the Highstate Outputter.

Windows

Python Version

Python 2 Windows API was design when Windows did not support Unicode. Windows now supports Unicode however to keep backwards compatibility Python 2 Windows API has not been changed. Python 3 Windows API supports Unicode. Salt Python 3 installer is the recommend choice for users who need characters other than Non-ASCII (7bit) characters.

pkg Execution module changes

Significant changes have been made to the win_pkg execution module. Users should test this release against their existing package sls definition files. These changes are also in 2016.11.9 & 2017.7.3.

  • pkg.list_available no longer defaults to refreshing the winrepo meta database.

  • pkg.install without a version parameter no longer upgrades software if the software is already installed. Use pkg.install version=latest or in a state use pkg.latest to get the old behavior.

  • pkg.list_pkgs now returns multiple versions if software installed more than once.

  • pkg.list_pkgs now returns 'Not Found' when the version is not found instead of '(value not set)' which matches the contents of the sls definitions.

  • pkg.remove() will wait up to 3 seconds (normally about a second) to detect changes in the registry after removing software, improving reporting of version changes.

  • pkg.remove() can remove latest software, if latest is defined in sls definition.

  • Documentation was update for the execution module to match the style in new versions, some corrections as well.

  • All install/remove commands are prefix with cmd.exe shell and cmdmod is called with a command line string instead of a list. Some sls files in saltstack/salt-winrepo-ng expected the commands to be prefixed with cmd.exe (i.e. the use of &).

  • Some execution module functions results, now behavour more like their Unix/Linux versions.

Installer

Changes to config handling

Behavior with existing configuration has changed. With previous windows installers the existing config was used and the master and minion id could be modified via the installer. It was problematic in that it didn't account for configuration that may be defined in the minion.d directory. This change gives you the option via a drop-down list to use one of the following:

  • Default Config: Use the config that comes with the installer

  • Existing Config: Use the current config without changes

  • Custom Config: Select a custom config using the file picker

The existing config option will only be available if the installer detects an existing config. If there is an existing config, and you choose Default or Custom, the existing config will be deleted, including the minion.d directory, and replaced by your selection.

The Default Config and Custom Config options will allow you to modify the Master and the Minion ID. Existing Config will leave the existing configuration unchanged.

These settings can be defined on the command line using the following switches:

  • /default-config

  • /custom-config=C:\Path\To\Custom\Config\minion

If neither option is passed and there is an existing config, the default is to use the existing config. If there is no existing config (new install) the default config will be used.

Multi-master configuration

The installer now has the ability to apply a multi-master configuration either from the GUI or the command line. The master field in the GUI can accept either a single master or a comma-separated list of masters. The command-line switch (/master=) can accept the same.

Command-line help

The Windows installer will now display command-line help when a help switch (/?) is passed.

New utils module salt.utils.pkg.win

A new utils module has been added, which gathers information about windows installed software. This is currently not used by any salt execution module or state at this time. Users are encouraged to run this and report any issues. Running the command with the detail option will be useful for anyone developing windows package definitions. With salt installed in the default location the following command will print the help message.

chcp 65001
c:\salt\bin\python.exe c:\salt\bin\lib\site-packages\salt\utils\pkg\win.py
c:\salt\bin\python.exe c:\salt\bin\lib\site-packages\salt\utils\pkg\win.py detail system

Salt Cloud Features

OpenStack Revamp

The OpenStack Driver has been rewritten mostly from scratch. Salt is now using the shade driver <https://docs.openstack.org/shade/latest/>.

With this, the nova driver is being deprecated.

openstack driver

There have also been several new modules and states added for managing OpenStack setups using shade as well.

keystone keystone role grant keystone group keystone role keystone service keystone user keystone domain keystone project keystone endpoint glance glance_image neutron neutron subnet neutron secgroup neutron secgroup rule neutron network

Pre-Flight Commands

Support has been added for specified "preflight commands" to run on a VM before the deploy script is run. These must be defined as a list in a cloud configuration file. For example:

my-cloud-profile:
  provider: linode-config
  image: Ubuntu 16.04 LTS
  size: Linode 2048
  preflight_cmds:
    - whoami
    - echo 'hello world!'

These commands will run in sequence before the bootstrap script is executed.

New salt-cloud Grains

When salt-cloud creates a new minion, it will now add grain information to the minion configuration file, identifying the resources originally used to create it.

The generated grain information will appear similar to:

grains:
  salt-cloud:
    driver: ec2
    provider: my_ec2:ec2
    profile: ec2-web

The generation of salt-cloud grains can be suppressed by the option enable_cloud_grains: 'False' in the cloud configuration file.

Upgraded Saltify Driver

The salt-cloud Saltify driver is used to provision machines which are not controlled by a dedicated cloud supervisor (such as typical hardware machines) by pushing a salt-bootstrap command to them and accepting them on the salt master. Creation of a node has been its only function and no other salt-cloud commands were implemented.

With this upgrade, it can use the salt-api to provide advanced control, such as rebooting a machine, querying it along with conventional cloud minions, and, ultimately, disconnecting it from its master.

After disconnection from ("destroying" on) one master, a machine can be re-purposed by connecting to ("creating" on) a subsequent master.

New Vagrant Driver

The salt-cloud Vagrant driver brings virtual machines running in a limited environment, such as a programmer's workstation, under salt-cloud control. This can be useful for experimentation, instruction, or testing salt configurations.

Using salt-api on the master, and a salt-minion running on the host computer, the Vagrant driver can create (vagrant up), restart (vagrant reload), and destroy (vagrant destroy) VMs, as controlled by salt-cloud profiles which designate a Vagrantfile on the host machine.

The master can be a very limited machine, such as a Raspberry Pi, or a small VagrantBox VM.

Python PyWinRM Module

Versions of pywinrm>=0.2.1 are finally able to disable validation of self signed certificates. Here for more information.

DigitalOcean

The DigitalOcean driver has been renamed to conform to the company name. The new driver name is digitalocean. The old name digital_ocean and a short one do will still be supported through virtual aliases, this is mostly cosmetic.

Azure Cloud

The azure sdk used for the azurearm cloud driver now depends on azure-cli>=2.0.12

New saltclass pillar/master_tops modules

This module clones the behaviour of reclass (http://reclass.pantsfullofunix.net/), without the need of an external app, and add several features to improve flexibility. Saltclass lets you define your nodes from simple yaml files (.yml) through hierarchical class inheritance with the possibility to override pillars down the tree.

Features

  • Define your nodes through hierarchical class inheritance

  • Reuse your reclass data with minimal modifications

    • applications => states

    • parameters => pillars

  • Use Jinja templating in your yaml definitions

  • Access to the following Salt objects in Jinja

    • __opts__

    • __salt__

    • __grains__

    • __pillars__

    • minion_id

  • Chose how to merge or override your lists using ^ character (see examples)

  • Expand variables ${} with possibility to escape them if needed ${} (see examples)

  • Ignores missing node/class and will simply return empty without breaking the pillar module completely - will be logged

An example subset of data is available here: https://git.mauras.ch/salt/saltclass/src/branch/master/examples

Terms usable in yaml files

Description

classes

A list of classes that will be processed in order

states

A list of states that will be returned by master_tops function

pillars

A yaml dictionary that will be returned by the ext_pillar function

environment

Node saltenv that will be used by master_tops

A class consists of:

  • zero or more parent classes

  • zero or more states

  • any number of pillars

A child class can override pillars from a parent class. A node definition is a class in itself with an added environment parameter for saltenv definition.

Class Names

Class names mimic salt way of defining states and pillar files. This means that default.users class name will correspond to one of these:

  • <saltclass_path>/classes/default/users.yml

  • <saltclass_path>/classes/default/users/init.yml

Saltclass Tree

A saltclass tree would look like this:

<saltclass_path>

Known limitation

Currently you can't have both a variable and an escaped variable in the same string as the escaped one will not be correctly rendered - '${xx}' will stay as is instead of being rendered as '${xx}'

Lists of comments in state returns

State functions can now return a list of strings for the comment field, as opposed to only a single string. This is meant to ease writing states with multiple or multi-part comments.

Beacon configuration changes

In order to remain consistent and to align with other Salt components such as states, support for configuring beacons using dictionary based configuration has been deprecated in favor of list based configuration. All beacons have a validation function which will check the configuration for the correct format and only load if the validation passes.

New requisites available in state compiler

require_any

The use of require_any demands that one of the required states executes before the dependent state. The state containing the require_any requisite is defined as the dependent state. The states specified in the require_any statement are defined as the required states. If at least one of the required state's execution succeeds, the dependent state will then execute. If all of the executions by the required states fail, the dependent state will not execute.

watch_any

The state containing the watch_any requisite is defined as the watching state. The states specified in the watch_any statement are defined as the watched states. When the watched states execute, they will return a dictionary containing a key named "changes".

If the "result" of any of the watched states is True, the watching state will execute normally, and if all of them are False, the watching state will never run. This part of watch mirrors the functionality of the require requisite.

If the "result" of any of the watched states is True and the "changes" key contains a populated dictionary (changes occurred in the watched state), then the watch requisite can add additional behavior. This additional behavior is defined by the mod_watch function within the watching state module. If the mod_watch function exists in the watching state module, it will be called in addition to the normal watching state. The return data from the mod_watch function is what will be returned to the master in this case; the return data from the main watching function is discarded.

If the "changes" key contains an empty dictionary, the watch requisite acts exactly like the require requisite (the watching state will execute if "result" is True, and fail if "result" is False in the watched state).

onchanges_any

The onchanges_any requisite makes a state only apply one of the required states generates changes, and if one of the watched state's "result" is True. This can be a useful way to execute a post hook after changing aspects of a system.

onfail_any

The onfail_any requisite allows for reactions to happen strictly as a response to the failure of at least one other state. This can be used in a number of ways, such as executing a second attempt to set up a service or begin to execute a separate thread of states because of a failure.

The onfail_any requisite is applied in the same way as require_any and watch_any.

Basic Slots support in state compiler

Slots extend the state syntax and allows you to do things right before the state function is executed. So you can make a decision in the last moment right before a state is executed.

Slot syntax looks close to the simple python function call. Here is a simple example:

copy-some-file:
  file.copy:
    - name: __slot__:salt:test.echo(text=/tmp/some_file)
    - source: __slot__:salt:test.echo(/etc/hosts)

Cryptographic layer changes

M2Crypto is coming back. We are making the crypto backend modular but in this release M2Crypto is enabled if it's importable by Python. If not Cryptodome or PyCrypto is used as it was in the previous releases. M2Crypto is used in the same way as PyCrypto so there would be no compatibility issues, different nodes could use different backends.

NaCL Module and Runner changes

In addition to argument changes in both the NaCL module and runner for future removal in the 3000 release, the default "box_type" has changed from secretbox to sealedbox. SecretBox is data encrypted using private key sk and Sealedbox is encrypted using public key pk.

utils functions reorganized into separate modules

Grain Deprecations

  • For smartos, some grains have been deprecated. These grains will be removed in 3000:

    • The hypervisor_uuid grain has been replaced with mdata:sdc:server_uuid

    • The datacenter grain has been replaced with mdata:sdc:datacenter_name

Pillar Deprecations

The legacy configuration for git_pillar has been removed. Please use the new configuration for git_pillar which was added in 2015.8.0, which is documented here.

Utils Deprecations

  • In salt.utils.cloud, the fire_event function now requires a sock_dir argument. It was previously optional.

Other Miscellaneous Deprecations

  • In version.py, the rc_info function was removed. Please use pre_info instead.

  • Warnings for moving away from the env option were removed. saltenv should be used instead. The removal of these warnings does not have a behavior change. Only the warning text was removed.

Minion Blackout

During a blackout, minions will not execute any remote execution commands, except for saltutil.refresh_pillar. Previously, support was added so that blackouts are enabled using a special pillar key, minion_blackout set to True and an optional pillar key minion_blackout_whitelist to specify additional functions that are permitted during blackout. This release adds support for using this feature in the grains as well, by using special grains keys minion_blackout and minion_blackout_whitelist.

Sentry Log Handler

Configuring sentry raven python client via project, servers, public_key and ``secret_key is deprecated and won't work with sentry clients > 3.0. Instead, the dsn config param must be used.

RAET transport

We haven't been doing development on RAET for quite some time and decided that 2018.3.0 is the time to announce the deprecation. RAET support will be removed in 3000. Please consider to move to zeromq or tcp transport instead of raet.
