Docker is a great tool for automating the deployment of Linux applications inside software containers, but to take full advantage of its potential each component of an application should run in its own individual container.
For complex applications with a lot of components, orchestrating all the containers to start up, communicate, and shut down together can quickly become unwieldy. The Docker community came up with a popular solution called Figwhich allowed you to use a single YAML file to orchestrate all your Docker containers and configurations. This became so popular that the Docker team decided to make Docker Compose based on the Fig source, which is now deprecated.
Docker Compose makes it easier for users to orchestrate the processes of Docker containers, including starting up, shutting down, and setting up intra-container linking and volumes.
Note: Even though the Prerequisites give instructions for installing Docker on Ubuntu By using the -o flag to specify the output file first rather than redirecting the output, this syntax avoids running into a permission denied error caused when using sudo. It illustrates the minimal configuration required to run a container using Docker Compose: a YAML file that calls a single image:.
The first line in the YAML file is used as part of the container name. The second line specifies which image to use to create the container. When we run the command docker-compose up it will look for a local image by the name we specified, hello-world. After pulling the image, docker-compose creates a container, attaches, and runs the hello program, which in turn confirms that the installation appears to be working:.
Docker containers only run as long as the command is active, so once hello finished running, the container stopped. Be sure to substitute the ID of your container:. While the Hello World example confirmed our installation, the simple configuration does not show one of the main benefits of Docker Compose — being able to bring a group of Docker containers up and down all at the same time.

In the documentation I read that net command is supported in docker-compose :. Those documents are outdated. I'm guessing the 1. Maybe I am answering very late. But I was also having a problem configuring host network in docker compose. Then I read the documentation thoroughly and made the changes and it worked. Please note this configuration is for docker-compose version "3. I am using host net to get some system metrics.

In the documentation I read that net command is supported in docker-compose : net Networking mode.It can monitor multiple RSS feeds for new tracks from your favorite artists and will grab, sort and rename them.
It can also be configured to automatically upgrade the quality of files already downloaded when a better quality format becomes available. Our images support multiple architectures such as xarm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here. The architectures supported by this image are:. This image provides various versions that are available via tags.
Others are considered under development and caution must be exercised when using them. Stable Lidarr releases.
Nightly Lidarr Releases. Here are some example snippets to help you get started creating a container from this image.
Compatible with docker-compose v2 schemas. Docker images are configured using parameters passed at runtime such as those above. For example, -p would expose port 80 from inside the container to be accessible from the host's IP on port outside the container. Application WebUI. Configuration files for Lidarr. Music files See note in Application setup. Path to your download folder for music See note in Application setup.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic. Special Note: Following our current folder structure will result in an inability to hardlink from your downloads to your Music folder because they are on seperate volumes.
To support hardlinking, simply ensure that the Music and downloads data are on a single volume. We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image if any can be accessed via the dynamic badge above. Shell access whilst the container is running:. To monitor the logs of the container in realtime:.

Creating your own home media server is easy, fun, and a great learning exercise. If you are familiar with Plex, you can skip down below where we get started with the install. If you are new to home media servers, take a chance to see quickly why we are choosing Plex. Plex Media Server is a media organization and streaming server software you can install on any operating system.
This incredibly easy to use software allows you to simply connect hard drives full of movies, tv shows, and music and then organize and display it in your web browser or from an app anywhere, including smart TVs. You can even share your content with as many people as you like, assuming your home server and bandwidth can handle it. There are a lot of alternative streaming servers out there you could choose besides Plex, you may even prefer them but I have found Plex to be the best overall, with the most features.
I would make the argument that the premium version of Plex, Plex Pass, is generally not needed by the large majority of users. The biggest competitor to Plex is also open source. Emby also has its own premium subscription that is on par price-wise as Plex. Though, some of the features such as access to podcasts or the ability to stream to a TV, are features that are free on Plex already. However, Jellyfin as well as Emby which Jellyfin is based on share a lot of common complaints with bugs in the app to plain sluggishness.
Jellyfin is something I plan on testing soon however, and maybe you should too! These are truly the only competition in existence. Some may try to honorable mention Kodi, but Kodi is not a media server. Kodi is a media center, just not a media server. Kodi works well to display local media but was not designed to allow you to watch that media anywhere.
This might be ok for your living room couch, but you are going to go through the trouble anyway, why not get the ability to stream? As mentioned in the title we are going to be using Docker as well as Docker compose on a Linux based server environment. This will allow us to run not only Plex, but most any software we want in an easily managed and scriptable environment.
I will be using Ubuntu Begin by installing your selected Linux OS to the machine. You can use a utility like Etcher to burn the ISO file to a flash drive as bootable media. From there, once the Flash drive is loaded with Linux, load it into the server computer and boot while smashing the F8 key. Check the BIOS splash screen for on-screen directions to find the key you need to hit. Install your operating system to the correct drive. You should ideally have a separate storage device from your media content for the OS.If your Docker application includes more than one container for example, a webserver and database running in separate containersbuilding, running, and connecting the containers from separate Dockerfiles is cumbersome and time-consuming.
Docker Compose solves this problem by allowing you to use a YAML file to define multi-container apps. You can configure as many containers as you want, how they should be built and connected, and where data should be stored. When the YAML file is complete, you can run a single command to build, run, and configure all of the containers.
This guide will explain how the docker-compose. To install on another distribution, or to install on Mac or Windows, see the official installation page. For Ubuntu Download the latest version of Docker Compose. Check the releases page and replace 1. This section will review an example Docker Compose file taken from the Docker official documentation. This will build and run the db and wordpress containers. Just as when running a single container with docker runthe -d flag starts the containers in detached mode.
Navigate to You can also use docker ps to further explore the resulting configuration:.
Most of this guide will focus on setting up containers using the services section. Here are some of the common directives used to set up and configure containers:. Many other configuration directives are available.
Making Your Own Home Media Server With Plex And Docker-Compose
See the Compose File reference for details. Create a docker-compose. Each entry in the services section will create a separate container when docker-compose is run. At this point, the section contains a single container based on the official Alpine distribution:.
From here you can begin to build an ecosystem of containers. You can define how they work together and communicate. The Distro service is the same as before.
The Database server contains the instructions for a postgres container, and the directives: volumes: This command shows the status of the containers, the port mapping, the names, and the last command running on them.
The Postgres Docker Entrypoint script is the last thing that launches when the container starts. This docker-compose file contains some new directives: environment and links. The first directive sets runtime level options within the container. The nginx container depends on the other two to execute.
In addition, the corresponding containers will be reachable at a hostname indicated by the alias.
In this case, pinging db from the web container will reach the database service. While you do not need the links directive for the containers to talk with each other, links can serve as a failsafe when starting the docker-compose application.
