Usage

Docker-compose

Here are some example snippets to help you get started creating a container.

version: '3.4'
services:
    postgres:
    image: elestio/postgres:${SOFTWARE_VERSION_TAG}
    restart: always
    environment:
        POSTGRES_DB: postgres
        POSTGRES_USER: postgres
        POSTGRES_PASSWORD: ${SOFTWARE_PASSWORD}
        PGDATA: /var/lib/postgresql/data
    volumes:
        - ./data:/var/lib/postgresql/data
    ports:
        - "172.17.0.1:5432:5432"

Environment variables

Maintenance

Logging

The Elestio Postgres Docker image sends the container logs to stdout. To view the logs, you can use the following command:

docker-compose logs -f

To stop the stack you can use the following command:

docker-compose down

Backup and Restore with Docker Compose

To make backup and restore operations easier, we are using folder volume mounts. You can simply stop your stack with docker-compose down, then backup all the files and subfolders in the folder near the docker-compose.yml file.

Creating a ZIP Archive For example, if you want to create a ZIP archive, navigate to the folder where you have your docker-compose.yml file and use this command:

zip -r myarchive.zip .

Restoring from ZIP Archive To restore from a ZIP archive, unzip the archive into the original folder using the following command:

unzip myarchive.zip -d /path/to/original/folder

Starting Your Stack Once your backup is complete, you can start your stack again with the following command:

docker-compose up -d

That's it! With these simple steps, you can easily backup and restore your data volumes using Docker Compose.
