To help in developing features, the Dockerfile and its entrypoint have been extended. The README.md explains stuff in detail, in short: - you can now run a Patroni cluster with a single command

# Patroni Dockerfile
|
|
You can run Patroni in a docker container using this Dockerfile, or by using the Docker image at
|
|
https://os-registry.stups.zalan.do/acid/patroni-1.0
|
|
|
|
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 os-registry.stups.zalan.do/acid/patroni:1.0
|
|
|
|
## 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 os-registry.stups.zalan.do/acid/patroni:1.0 --members=2 --name=bravo
|
|
