linuxserver/codimd

Codimd gives you access to all your files wherever you are.

CodiMD is a real-time, multi-platform collaborative markdown note editor. This means that you can write notes with other people on your desktop, tablet or even on the phone. You can sign-in via multiple auth providers like Facebook, Twitter, GitHub and many more on the homepage.

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 linuxserver/codimd 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

Usage

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

docker

docker create \
  --name=codimd \
  -e PUID=1000 \
  -e PGID=1000 \
  -e DB_HOST=<hostname or ip> \
  -e DB_PORT=3306 \
  -e DB_USER=codimd \
  -e DB_PASS=<secret password> \
  -e DB_NAME=codimd \
  -e TZ=Europe/London \
  -p 3000:3000 \
  -v </path/to/appdata>:/config \
  --restart unless-stopped \
  linuxserver/codimd

docker-compose

Compatible with docker-compose v2 schemas.

version: "3"
services:
  mariadb:
    image: linuxserver/mariadb:latest
    container_name: codimd_mariadb
    restart: always
    volumes:
      - <path to mariadb data>:/config
    environment:
      - MYSQL_ROOT_PASSWORD=<secret password>
      - MYSQL_DATABASE=codimd
      - MYSQL_USER=codimd
      - MYSQL_PASSWORD=<secret password>
      - PGID=1000

  codimd:
    image: linuxserver/codimd:latest
    container_name: codimd
    restart: always
    depends_on:
      - mariadb
    volumes:
      - <path to config>:/config
    environment:
      - DB_HOST=mariadb
      - DB_USER=codimd
      - DB_PASS=<secret password>
      - DB_NAME=codimd
      - DB_PORT=3306
      - PGID=1000
      - PUID=1000
      - TZ=Europe/London
    ports:
      - "3000:3000"

Parameters

Docker 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.

Ports (`-p`)

Parameter	Function
`3000`	If you wish to access this container from http://{IP}:${PORT}` this must be left unchanged.

Environment Variables (`-e`)

Env	Function
`PUID=1000`	for UserID - see below for explanation
`PGID=1000`	for GroupID - see below for explanation
`DB_HOST=<hostname or ip>`	Host address of mysql database
`DB_PORT=3306`	Port to access mysql database default is 3306
`DB_USER=codimd`	Database user
`DB_PASS=<secret password>`	Database password
`DB_NAME=codimd`	Database name
`TZ=Europe/London`	Specify a timezone to use EG Europe/London.

Volume Mappings (`-v`)

Volume	Function
`/config`	CodiMD config and configurable files

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

CodiMD web interface can be accessed http://${IP}:3000/, if you want to use a custom domain or anything besides port 3000 you will need to leverage their env settings for callbacks: (specifically for CMD_DOMAIN and CMD_URL_ADDPORT)

Full list of CodiMD options

For convience we provide a working example using Mysql as a backend in this document, if you do not wish to use our custom environment values or a Mysql database backend feel free to leverage any of the settings laid out in the link above.

To run behind a reverse proxy we have a preconfigured config using docker networking included in our LetsEncrypt image and you can read how to use this in the Reverse Proxy Confs repository

Docker Mods

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.

Support Info

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