Patroni Dockerfile

You can run Patroni in a docker container using this Dockerfile, or by using one of the Docker image at

https://registry.opensource.zalan.do/v1/repositories/acid/patroni/tags

This Dockerfile is meant in aiding development of Patroni and quick testing of features. It is not a production-worthy Dockerfile

Examples

Standalone Patroni

docker run -d registry.opensource.zalan.do/acid/patroni:1.0-SNAPSHOT

Multiple Patroni's communicating with a standalone etcd inside Docker

Basically what you would do would be:

Run 1 container which provides etcd
```
  docker run -d <IMAGE> --etcd-only
```
Run n containers running Patroni, passing the --etcd option to the docker run command
```
  docker run -d <IMAGE> --etcd=<IP FROM etcd CONTAINER:PORT>
```

To automate this you can run the following script:

dev_patroni_cluster.sh [OPTIONS]

Options:

    --image     IMAGE    The Docker image to use for the cluster
    --members   INT      The number of members for the cluster
    --name      NAME     The name of the new cluster

Example session:

$ ./dev_patroni_cluster.sh --image registry.opensource.zalan.do/acid/patroni:1.0-SNAPSHOT --members=2 --name=bravo
