Copy pillar data from a bucket in Amazon S3
The S3 pillar can be configured in the master config file with the following options
ext_pillar:
- s3:
bucket: my.fancy.pillar.bucket
keyid: KASKFJWAKJASJKDAJKSD
key: ksladfDLKDALSFKSD93q032sdDasdfasdflsadkf
multiple_env: False
environment: base
prefix: somewhere/overthere
verify_ssl: True
service_url: s3.amazonaws.com
kms_keyid: 01234567-89ab-cdef-0123-4567890abcde
s3_cache_expire: 30
s3_sync_on_update: True
path_style: False
https_enable: True
The bucket
parameter specifies the target S3 bucket. It is required.
The keyid
parameter specifies the key id to use when access the S3 bucket.
If it is not provided, an attempt to fetch it from EC2 instance meta-data will
be made.
The key
parameter specifies the key to use when access the S3 bucket. If it
is not provided, an attempt to fetch it from EC2 instance meta-data will be made.
The multiple_env
defaults to False. It specifies whether the pillar should
interpret top level folders as pillar environments (see mode section below).
The environment
defaults to 'base'. It specifies which environment the
bucket represents when in single environments mode (see mode section below). It
is ignored if multiple_env is True.
The prefix
defaults to ''. It specifies a key prefix to use when searching
for data in the bucket for the pillar. It works when multiple_env is True or False.
Essentially it tells ext_pillar to look for your pillar data in a 'subdirectory'
of your S3 bucket
The verify_ssl
parameter defaults to True. It specifies whether to check for
valid S3 SSL certificates. NOTE If you use bucket names with periods, this
must be set to False else an invalid certificate error will be thrown (issue
#12200).
The service_url
parameter defaults to 's3.amazonaws.com'. It specifies the
base url to use for accessing S3.
The kms_keyid
parameter is optional. It specifies the ID of the Key
Management Service (KMS) master key that was used to encrypt the object.
The s3_cache_expire
parameter defaults to 30s. It specifies expiration
time of S3 metadata cache file.
The s3_sync_on_update
parameter defaults to True. It specifies if cache
is synced on update rather than jit.
The path_style
parameter defaults to False. It specifies whether to use
path style requests or dns style requests
The https_enable
parameter defaults to True. It specifies whether to use
https protocol or http protocol
This pillar can operate in two modes, single environment per bucket or multiple environments per bucket.
Single environment mode must have this bucket structure:
s3://<bucket name>/<prefix>/<files>
Multiple environment mode must have this bucket structure:
s3://<bucket name>/<prefix>/<environment>/<files>
If you wish to define your pillar data entirely within S3 it's recommended that you use the prefix= parameter and specify one entry in ext_pillar for each environment rather than specifying multiple_env. This is due to issue #22471 (https://github.com/saltstack/salt/issues/22471)
