linuxserver/mylar3

Mylar3 is an automated Comic Book downloader (cbr/cbz) for use with NZB and torrents written in python. It supports SABnzbd, NZBGET, and many torrent clients in addition to DDL.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling ghcr.io/linuxserver/mylar3 should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Version Tags

This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.

Tag	Description
latest	Stable Mylar3 releases
nightly	Commits to Mylar3 `python3-dev` branch

Usage

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

docker-compose (recommended)

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  mylar3:
    image: ghcr.io/linuxserver/mylar3
    container_name: mylar3
    environment:
      - PUID=1000
      - PGID=1000
    volumes:
      - /path/to/data:/config
      - /path/to/comics:/comics
      - /path/to/downloads:/downloads
    ports:
      - 8090:8090
    restart: unless-stopped

docker cli

docker run -d \
  --name=mylar3 \
  -e PUID=1000 \
  -e PGID=1000 \
  -p 8090:8090 \
  -v /path/to/data:/config \
  -v /path/to/comics:/comics \
  -v /path/to/downloads:/downloads \
  --restart unless-stopped \
  ghcr.io/linuxserver/mylar3

Parameters

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Parameter	Function
`-p 8090`	WebUI
`-e PUID=1000`	for UserID - see below for explanation
`-e PGID=1000`	for GroupID - see below for explanation
`-v /config`	Where mylar should store config files.
`-v /comics`	Map to your comics folder.
`-v /downloads`	Map to your downloads folder.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags) permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Application Setup

The web ui for settings etc, is on <your-ip>:8090 For more detailed setup options, refer to Mylar3.

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

Shell access whilst the container is running: docker exec -it mylar3 /bin/bash
To monitor the logs of the container in realtime: docker logs -f mylar3
container version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' mylar3
image version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/mylar3

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

Update all images: docker-compose pull
- or update a single image: docker-compose pull mylar3
Let compose update all containers as necessary: docker-compose up -d
- or update a single container: docker-compose up -d mylar3
You can also remove the old dangling images: docker image prune

Via Docker Run

Update the image: docker pull ghcr.io/linuxserver/mylar3
Stop the running container: docker stop mylar3
Delete the container: docker rm mylar3
Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)
You can also remove the old dangling images: docker image prune

Via Watchtower auto-updater (only use if you don't remember the original parameters)

Pull the latest image at its tag and replace it with the same env variables in one run:

docker run --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once mylar3

You can also remove the old dangling images: docker image prune

Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.

Image Update Notifications - Diun (Docker Image Update Notifier)

We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-mylar3.git
cd docker-mylar3
docker build \
  --no-cache \
  --pull \
  -t ghcr.io/linuxserver/mylar3:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.

Versions

21.12.20: - Release nightly tag based on commits to upstream python3-dev branch.
28.09.20: - Initial release.
