Kombinat\n\n:see_no_evil: A first try to curate [Auto Scaling](https://aws.amazon.com/de/autoscaling/) with [CoreOS](https://coreos.com/) in [AWS](https://aws.amazon.com/).\n\nWe will curate many things in the months to come, but right now, there are these things.\n\n* [etcd](https://coreos.com/etcd/docs/latest/)\n* EC2 Peers\n\n## Features\n\n### etcd\n\nWe curate the etcd cluster members, but removing members that are unreachable, because related AutoScaling instances have vanished.\n\n\u003e Please, keep in mind the (N+1)/2 limit of scaling members of an etcd cluster\n\n## Get Started\n\n### Setup\n\nSetting up the needed deps and restore the relevant dependencies.\n\n```\nmake deps \u0026\u0026 make restore\n```\n\nBuild the project and see view the produced binaries.\n\n```\nmake build \u0026\u0026 ls -l ./bin\n```\n\n\u003e There is also a `Dockerfile` included, which allows to run `kombinat` in a container with [Supervisord](http://supervisord.org/)\n\n\u003e The docker has to be on the host net `docker run --rm --network host -d pixelmilk/kombinat`\n\n### EC2 IAM Policy\n\n\u003e We may mention the [ec2-metadata](https://github.com/axelspringer/ec2-metadata) project, which allows to test the Instance Metadata and User Data Service :grin:\n\nBeside the need to access the to [Instance Metadata and User Data Service](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html) we need an IAM Role with the following IAM Policy for the EC2 Instances in the AutoScaling Groups.\n\n```\n{\n  \"Version\": \"2012-10-17\",\n  \"Statement\": [\n      {\n          \"Effect\": \"Allow\",\n          \"Action\": \"ec2:Describe*\",\n          \"Resource\": \"*\"\n      },\n      {\n          \"Effect\": \"Allow\",\n          \"Action\": \"elasticloadbalancing:Describe*\",\n          \"Resource\": \"*\"\n      },\n      {\n          \"Effect\": \"Allow\",\n          \"Action\": [\n              \"cloudwatch:ListMetrics\",\n              \"cloudwatch:GetMetricStatistics\",\n              \"cloudwatch:Describe*\"\n          ],\n          \"Resource\": \"*\"\n      },\n      {\n          \"Effect\": \"Allow\",\n          \"Action\": \"autoscaling:Describe*\",\n          \"Resource\": \"*\"\n      }\n  ]\n}\n```\n\nThis policy allows to read the state of the AutoScaling Groups and the related EC2 instances.\n\n#
