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`.
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 \(if any\) can be accessed via the dynamic badge above.
