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.
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](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
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.
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](https://en.wikipedia.org/wiki/Umask) before asking for support.
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`.
THIS IMAGE IS DEPRECATED. CodiMD is rebranded as `HedgeDoc` and the new docker image is at [linuxserver/hedgedoc](https://github.com/linuxserver/docker-hedgedoc).
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)
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](https://github.com/linuxserver/reverse-proxy-confs/blob/master/codimd.subdomain.conf.sample) using docker networking included in our [LetsEncrypt](https://github.com/linuxserver/docker-letsencrypt) image and you can read how to use this in the [Reverse Proxy Confs repository](https://github.com/linuxserver/reverse-proxy-confs/#how-to-use-these-reverse-proxy-configs)

We publish various [Docker Mods](https://github.com/linuxserver/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.
