# Kombinat
: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/).
We will curate many things in the months to come, but right now, there are these things.
* [etcd](https://coreos.com/etcd/docs/latest/)
* EC2 Peers
## Features
### etcd
We curate the etcd cluster members, but removing members that are unreachable, because related AutoScaling instances have vanished.
> Please, keep in mind the (N+1)/2 limit of scaling members of an etcd cluster
## Get Started
### Setup
Setting up the needed deps and restore the relevant dependencies.
```
make deps && make restore
```
Build the project and see view the produced binaries.
```
make build && ls -l ./bin
```
> There is also a `Dockerfile` included, which allows to run `kombinat` in a container with [Supervisord](http://supervisord.org/)
> The docker has to be on the host net `docker run --rm --network host -d pixelmilk/kombinat`
### EC2 IAM Policy
> 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:
Beside 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.
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "ec2:Describe*",
"Resource": "*"
},
{
"Effect": "Allow",
"Action": "elasticloadbalancing:Describe*",
"Resource": "*"
},
{
"Effect": "Allow",
"Action": [
"cloudwatch:ListMetrics",
"cloudwatch:GetMetricStatistics",
"cloudwatch:Describe*"
],
"Resource": "*"
},
{
"Effect": "Allow",
"Action": "autoscaling:Describe*",
"Resource": "*"
}
]
}
```
This policy allows to read the state of the AutoScaling Groups and the related EC2 instances.
