PSQL Docker Installation

.sh

```
sudo mkdir -p ~/work/data/psql11 && \
sudo docker run \
--name ifca.training.psql11 \
-e POSTGRES_PASSWORD=abc123 \
-e PGDATA=pgdata \
-p 5432:5432 \
-v ~/work/data/psql11:/var/lib/postgresql/data/pgdata \
--restart unless-stopped \
-d \
postgres:11-alpine
```

Then you have to `docker exec -it ${dockerId} "/bin/bash"`.

Then `su postgres`.
Then `psql`.
Then `CREATE DATABASE ${databaseName};`.
