salt.states.boto_asg¶

Manage Autoscale Groups¶

New in version 2014.7.0.

Create and destroy autoscale groups. Be aware that this interacts with Amazon's services, and so may incur charges.

This module uses boto, which can be installed via package, or pip.

This module accepts explicit autoscale credentials but can also utilize IAM roles assigned to the instance through Instance Profiles. Dynamic credentials are then automatically obtained from AWS API and no further configuration is necessary. More Information available at:

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

If IAM roles are not used you need to specify them either in a pillar or in the minion's config file:

asg.keyid: GKTADJGHEIQSXMKKRBJ08H
asg.key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

It's also possible to specify key, keyid and region via a profile, either as a passed in dict, or as a string to pull from pillars or minion config:

myprofile:
    keyid: GKTADJGHEIQSXMKKRBJ08H
    key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
    region: us-east-1

Ensure myasg exists:
  boto_asg.present:
    - name: myasg
    - launch_config_name: mylc
    - availability_zones:
      - us-east-1a
      - us-east-1b
    - min_size: 1
    - max_size: 1
    - desired_capacity: 1
    - load_balancers:
      - myelb
    - suspended_processes:
        - AddToLoadBalancer
        - AlarmNotification
    - scaling_policies
        - adjustment_type: ChangeInCapacity
        - as_name: api-production-iad
        - cooldown: 1800
        - min_adjustment_step: None
        - name: ScaleDown
        - scaling_adjustment: -1
    - region: us-east-1
    - keyid: GKTADJGHEIQSXMKKRBJ08H
    - key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

# Using a profile from pillars.
Ensure myasg exists:
  boto_asg.present:
    - name: myasg
    - launch_config_name: mylc
    - availability_zones:
      - us-east-1a
      - us-east-1b
    - min_size: 1
    - max_size: 1
    - desired_capacity: 1
    - load_balancers:
      - myelb
    - profile: myprofile

# Passing in a profile.
Ensure myasg exists:
  boto_asg.present:
    - name: myasg
    - launch_config_name: mylc
    - availability_zones:
      - us-east-1a
      - us-east-1b
    - min_size: 1
    - max_size: 1
    - desired_capacity: 1
    - load_balancers:
      - myelb
    - profile:
        keyid: GKTADJGHEIQSXMKKRBJ08H
        key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
        region: us-east-1

# Deleting an autoscale group with running instances.
Ensure myasg is deleted:
  boto_asg.absent:
    - name: myasg
    # If instances exist, we must force the deletion of the asg.
    - force: True

It's possible to specify cloudwatch alarms that will be setup along with the ASG. Note the alarm name will be the name attribute defined, plus the ASG resource name.

Ensure myasg exists:
  boto_asg.present:
    - name: myasg
    - launch_config_name: mylc
    - availability_zones:
      - us-east-1a
      - us-east-1b
    - min_size: 1
    - max_size: 1
    - desired_capacity: 1
    - load_balancers:
      - myelb
    - profile: myprofile
    - alarms:
        CPU:
          name: 'ASG CPU **MANAGED BY SALT**'
          attributes:
            metric: CPUUtilization
            namespace: AWS/EC2
            statistic: Average
            comparison: '>='
            threshold: 65.0
            period: 60
            evaluation_periods: 30
            unit: null
            description: 'ASG CPU'
            alarm_actions: [ 'arn:aws:sns:us-east-1:12345:myalarm' ]
            insufficient_data_actions: []
            ok_actions: [ 'arn:aws:sns:us-east-1:12345:myalarm' ]

You can also use alarms from pillars, and override values from the pillar alarms by setting overrides on the resource. Note that 'boto_asg_alarms' will be used as a default value for all resources, if defined and can be used to ensure alarms are always set for an ASG resource.

Setting the alarms in a pillar:

my_asg_alarm:
  CPU:
    name: 'ASG CPU **MANAGED BY SALT**'
    attributes:
      metric: CPUUtilization
      namespace: AWS/EC2
      statistic: Average
      comparison: '>='
      threshold: 65.0
      period: 60
      evaluation_periods: 30
      unit: null
      description: 'ASG CPU'
      alarm_actions: [ 'arn:aws:sns:us-east-1:12345:myalarm' ]
      insufficient_data_actions: []
      ok_actions: [ 'arn:aws:sns:us-east-1:12345:myalarm' ]

Overriding the alarm values on the resource:

Ensure myasg exists:
  boto_asg.present:
    - name: myasg
    - launch_config_name: mylc
    - availability_zones:
      - us-east-1a
      - us-east-1b
    - min_size: 1
    - max_size: 1
    - desired_capacity: 1
    - load_balancers:
      - myelb
    - profile: myprofile
    - alarms_from_pillar: my_asg_alarm
    # override CPU:attributes:threshold
    - alarms:
        CPU:
          attributes:
            threshold: 50.0

The launch config name will be the launch_config_name followed by a hyphen followed by a hash of the launch_config dict contents. Example:

my_asg:
  boto_asg.present:
  - launch_config:

If any alarm actions include ":self:" this will be replaced with the asg name. For example, alarm_actions reading "['scaling_policy:self:ScaleUp']" will map to the arn for this asg's scaling policy named "ScaleUp". In addition, any alarms that have only scaling_policy as actions will be ignored if min_size is equal to max_size for this ASG.
