boto3_elb

Manage Elastic Load Balancers (ELB) using boto3.

Renamed from boto_elb to boto3_elb and updated to call the refactored boto3_elb execution module.

Create and destroy ELBs. Be aware that this interacts with Amazon’s services, and so may incur charges.

  • boto3 >= 1.28.0

  • botocore >= 1.31.0

This module uses boto3, which can be installed via package, or pip.

Create and destroy Elastic Load Balancers (ELB). Be aware that this interacts with Amazon’s services, and so may incur charges.

This module uses boto3, which can be installed via package, or pip.

This module accepts explicit ELB 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 the minion’s config file or as a profile. For example, to specify them in the minion’s config file:

elb.keyid: GKTADJGHEIQSXMKKRBJ08H
elb.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

# Using a profile from pillars
Ensure myelb ELB exists:
    boto3_elb.present:
        - name: myelb
        - region: us-east-1
        - profile: myelbprofile

# Passing in a profile
Ensure myelb ELB exists:

        - region: us-east-1
        - profile:

            key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs

It’s possible to specify attributes from pillars by specifying a pillar. You can override the values defined in the pillard by setting the attributes on the resource. The module will use the default pillar key ‘boto_elb_attributes’, which allows you to set default attributes for all ELB resources.

Setting the attributes pillar:

my_elb_attributes:
  cross_zone_load_balancing:
    enabled: true
  connection_draining:
    enabled: true
    timeout: 20
  access_log:
    enabled: true
    s3_bucket_name: 'mybucket'
    s3_bucket_prefix: 'my-logs'
    emit_interval: 5

Overriding the attribute values on the resource:

Ensure myelb ELB exists:
    boto3_elb.present:
        - name: myelb
        - region: us-east-1
        - attributes_from_pillar: my_elb_attributes
        # override cross_zone_load_balancing:enabled
        - attributes:
            cross_zone_load_balancing:
              enabled: false
        - profile: myelbprofile

It’s possible to specify cloudwatch alarms that will be setup along with the ELB. Note the alarm name will be defined by the name attribute provided, plus the ELB resource name.

Ensure myelb ELB exists:
    boto3_elb.present:
        - name: myelb
        - region: us-east-1
        - profile: myelbprofile
        - alarms:
            UnHealthyHostCount:
              name: 'ELB UnHealthyHostCount **MANAGED BY SALT**'
              attributes:
                metric: UnHealthyHostCount
                namespace: AWS/ELB
                statistic: Average
                comparison: '>='
                threshold: 1.0
                period: 600
                evaluation_periods: 6
                unit: null
                description: ELB UnHealthyHostCount
                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_elb_alarms’ will be used as a default value for all resources, if defined and can be used to ensure alarms are always set for a resource.

Setting the alarms in a pillar:

my_elb_alarm:
  UnHealthyHostCount:
    name: 'ELB UnHealthyHostCount **MANAGED BY SALT**'
    attributes:
      metric: UnHealthyHostCount
      namespace: AWS/ELB
      statistic: Average
      comparison: '>='
      threshold: 1.0
      period: 600
      evaluation_periods: 6
      unit: null
      description: ELB UnHealthyHostCount
      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 myelb ELB exists:
    boto3_elb.present:
        - name: myelb
        - region: us-east-1
        - profile: myelbprofile
        - alarms_from_pillar: my_elb_alarm
        # override UnHealthyHostCount:attributes:threshold
        - alarms:
            UnHealthyHostCount:
              attributes:
                threshold: 2.0

Tags can also be set:

Ensure myelb ELB exists:
    boto3_elb.present:
        - name: myelb
        - region: us-east-1
        - profile: myelbprofile
        - tags:
            MyTag: 'My Tag Value'
            OtherTag: 'My Other Value'

Added in version 1.0.0.

cnames

A list of cname dicts with attributes needed for the DNS add_record state. By default the boto_route53.add_record state will be used, which requires: name, zone, ttl, and identifier. See the boto_route53 state for information about these attributes. Other DNS modules can be called by specifying the provider keyword. the cnames dict will be passed to the state as kwargs.

See the salt.states.boto_route53 state for information about these attributes.
