![]() You now have 3 services defined in there: heimdall, nginx and mariadb. Version : "2.1" services : heimdall : image : linuxserver/heimdall container_name : heimdall volumes : - /home/user/appdata/heimdall:/config environment : - PUID=1000 - PGID=1000 - TZ=Europe/London ports : - 80:80 - 443:443 restart : unless-stopped nginx : image : linuxserver/nginx container_name : nginx environment : - PUID=1000 - PGID=1000 - TZ=Europe/London volumes : - /home/user/appdata/nginx:/config ports : - 81:80 - 444:443 restart : unless-stopped mariadb : image : linuxserver/mariadb container_name : mariadb environment : - PUID=1000 - PGID=1000 - MYSQL_ROOT_PASSWORD=ROOT_ACCESS_PASSWORD - TZ=Europe/London volumes : - /home/user/appdata/mariadb:/config ports : - 3306:3306 restart : unless-stopped Let's say you have the following in a yaml file named compose.yml: Copy the contents below the services: line in any of our readme yaml samples into the same yaml file and the docker compose up/down commands will apply to all services at once. You can have multiple services managed by a single compose yaml. To bring down the services, simply do docker compose down or docker compose -f /path/to/heimdall.yml down and all containers defined by the yml will be stopped and destroyed. ![]() heimdall.yml, then you can define it in the command with -f: docker compose -f /path/to/heimdall.yml up -d If you want to do it from a different folder or if you named the yaml file differently, ie. up means bring the services up, and -d means do it in the background. If you save the above snippet in a file named compose.yml, you can simply run docker compose up -d from within the same folder and the heimdall image will be automatically pulled, and a container will be created and started. ![]() Version : "2.1" services : heimdall : image : linuxserver/heimdall container_name : heimdall volumes : - /home/user/appdata/heimdall:/config environment : - PUID=1000 - PGID=1000 - TZ=Europe/London ports : - 80:80 - 443:443 restart : unless-stopped You can install docker compose manually via the following commands: Install docker from the official repos as described here, making sure that you install the docker-compose-plugin package as part of the process. They publish this plugin for multiple arches as opposed to the x86_64 only binaries for v1.x. Starting with version 2, Docker started publishing docker compose as a go based plugin for docker (rather than a python based standalone binary). The best course of action if you do not know how to do this or are unwilling to research, is to stick to alphanumeric characters only. In the case of passwords with special characters this can mean escaping them properly ($ is the escape character) or properly quoting the variable. Note that when inputting data for variables, you must follow standard YAML rules. Then, with a single command, you create and start all the services from your configuration. With Compose, you use a YAML file to configure your application’s services.
