gavinmroy/alpine-rabbitmq-autocluster repository overview

GitHub Repo: gmr/alpine-rabbitmq-autocluster⁠

** Configuration ** All configuration of the auto-cluster plugin should be done via environment variables.

See the RabbitMQ AutoCluster⁠ plugin Wiki for configuration settings.

Example Usage The following example configures the autocluster plugin for use in an AWS EC2 Autoscaling group:

    docker run --name rabbitmq -d \
      -e AUTOCLUSTER_TYPE=aws \
      -e AUTOCLUSTER_CLEANUP=true \
      -e CLEANUP_WARN_ONLY=false \
      -e AWS_DEFAULT_REGION=us-east-1 \
      -p 4369:4369 \
      -p 5672:5672 \
      -p 15672:15672 \
      -p 25672:25672 \

To use the AWS autocluster features, you will need an IAM policy that allows the plugin to discover the node list. The following is an example of such a policy:

  {
      "Version": "2012-10-17",
      "Statement": [
          {
              "Effect": "Allow",
              "Action": [
                  "autoscaling:DescribeAutoScalingInstances",
                  "ec2:DescribeInstances"
              ],
              "Resource": [
                  "*"
              ]
          }
      ]
  }

If you do not want to use the IAM role for the instances, you could create a role and specify the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY when starting the container.

For simple testing, there is an AWS CloudFormation template⁠ in the GitHub repo⁠ for the image.
