# Run A Basic PostgreSQL Server In Docker
|
|
|
|
Here is a basic `docker-compose.yml` file for spinning up a Docker container
|
|
that runs a PostgreSQL server on port 5432. This is what I use to create a
|
|
locally-running PostgreSQL server that lives inside a docker container.
|
|
|
|
```yaml
|
|
version: "3.7"
|
|
services:
|
|
postgres:
|
|
image: postgres:latest
|
|
restart: always
|
|
environment:
|
|
- POSTGRES_USER=postgres
|
|
- POSTGRES_PASSWORD=postgres
|
|
- POSTGRES_DB=postgres
|
|
ports:
|
|
- "5432:5432"
|
|
volumes:
|
|
- ./postgres-data:/var/lib/postgresql/data
|
|
```
|
|
|
|
To create the docker container and start it up, run the following command from
|
|
the same directory where you put this file:
|
|
|
|
```bash
|
|
$ docker compose up
|
|
```
|
|
|
|
This command knows to look for the `docker-compose.yml` file though you can
|
|
always be explicit about the file with the `-f` option.
|
|
|
|
This configuration points at `postgres:latest` which currently is `16.1`. To
|
|
run a different major version, you can change the `image` to something like
|
|
`postgres:15`. See [Docker Hub](https://hub.docker.com/_/postgres) for more
|
|
options.
