Manage ELBs

2014.7.0 新版功能.

Create and destroy ELBs. 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 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 here.

If IAM roles are not used you need to specify them either in a pillar file or 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 passed in as a dict, or as a string to pull from pillars or minion config:

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

Ensure myelb ELB exists:
    boto_elb.present:
        - name: myelb
        - region: us-east-1
        - availability_zones:
            - us-east-1a
            - us-east-1c

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

# Passing in a profile
Ensure myelb ELB exists:
    boto_elb.present:
        - name: myelb
        - region: us-east-1
        - profile:
            keyid: GKTADJGHEIQSXMKKRBJ08H
            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:
    boto_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:
    boto_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:
    boto_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:
