+# Postgres
+
+A PostgreSQL database for use in the [Deis](http://deis.io) open source PaaS.
+
+This Docker image is based on the official
+[postgres](https://registry.hub.docker.com/_/postgres/) image.
+
+Master/slave replication and leader election code is largely inspired by [`compose/governor`](https://github.com/compose/governor).
+
+Please add any [issues](https://github.com/deis/postgres/issues) you find with this software.
+
+
+## Deploying
+
+In order to run this component in Kubernetes, a few prerequisites are needed:
+
+ - An AWS account with S3 enabled
+ - An external etcd cluster
+ - your own kubernetes cluster
+
+In Deis, these services are provided to you automatically through [the store](http://docs.deis.io/en/latest/understanding_deis/components/#store)
+and [etcd](https://github.com/technosophos/etcd) components.
+
+To build a dev release of this image, you will also need your own registry, but DockerHub or
+[Quay](https://quay.io/) will do fine here. To build, run:
+
+```bash
+$ make build
+$ docker build -t deis/postgres:v0.0.1
+$ docker push deis/postgres:v0.0.1
+```
+
+This will compile the Docker image and push it to your registry.
+
+Then, you'll need to modify the kubernetes manifests to point to your S3 account and your etcd
+cluster. Open up the replication controller manifest and change the values:
+
+```
+$ git diff
+diff --git a/manifests/postgres-rc.json b/manifests/postgres-rc.json
+index a5cbb23..70d3bc2 100644

+
+```

+deis-database-6wy8o   1/1       Running   0          32s
+deis-database-rh00d   0/1       Running   0          32s
+```
+
+You can then query these images as you would with any other Kubernetes pod:
+
+```
+$ kubectl logs -f deis-database-6wy8o
+$ kubectl exec -it deis-database-6wy8o psql
+```
+
+
+## Testing
+
+**Note**: At this time, tests from Deis v1 are still being ported over.
+
+You can run the test suite with
+
+```
+$ make test
+```
