What is Codiad

Codiad is a web-based IDE framework with a small footprint and minimal requirements.

You can add many plugins from the Web UI by opening the right side bar and clicking Marketplace.

Features of this image

  • Simple or Lean:
    • latest is based on Ubuntu, contains docker and docker-compose binaries, and is easy to extend so as to include required development tools.
    • alpine is base on Linux Alpine (very small) with S6 supervisor (lightweight) but some features may not work and it does not support custom CODIAD_UID/CODIAD_GID.
  • Performant: Using Nginx + PHP-FPM (very performant).
  • Secure:
    • Runs as non-root (Nginx run as nginx and PHP-FPM run as UID 2743 by default once started).
    • Includes a brute-force attack protection.

How to use this image

docker run --rm -p 8080:80 \
    -v $PWD/code:/code \
    -v /etc/localtime:/etc/localtime:ro \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \

Then open your browser at http://localhost:8080.


  • -p 80 ‒ the port to expose.
  • -e CODIAD_UID and -e CODIAD_GID(optional) sets the user / group ID to use for PHP
    (i.e. it'll be the user / group under which all Codiad users will execute commands if they use the Terminal plugin or such).
  • -v /code(optional) persists your configuration and installed plugins (you may also use a Docker volume).
  • -v /etc/localtime(optional) used for timesync.
  • -v /var/run/docker.sock(optional) allows to build and run Docker images from within Codiad
    (e.g. using the Terminal plugin or Macros plugin). It also gives often nearly root access to your Codiad
    users so use it with care. If you see client API incompatible, you may try to mount also -v /usr/bin/docker:/usr/bin/docker:ro.
    Just ensure that user CODIAD_UID:CODIAD_GID has read access to that socket file.

User / Group Identifiers

TL;DR - The CODIAD_UID and CODIAD_UID values set the user / group you'd like your container to 'run as'. This can be a user you've created or even root (not recommended).

Part of what makes our containers work so well is by allowing you to specify your own PUID and PGID. This avoids nasty permissions errors with relation to data volumes (-v flags). When an application is installed on the host OS it is normally added to the common group called users, Docker apps due to the nature of the technology can't be added to this group. So we added this feature to let you easily choose when running your containers.

Setting up your projects

  • Store your projects somewhere below /code/, for data persistence (or mount another volume).
  • Install common plug-ins via the web interface, like:

    • Collaboration
    • Terminal
      • Change /code/plugins/Codiad-Terminal-master/emulator/term.php to change terminal password (default is terminal).
    • CodeGit

      • Change /code/plugins/Codiad-CodeGit-master/ to add Git user/pass.
      • To set up SSH key (see also Codiad Wiki) you can run using Codiad Terminal:

        ssh-keygen -f ~/.ssh/id_rsa
        ssh-keyscan -t rsa,dsa $DOMAIN_NAME >> ~/.ssh/known_hosts
        cat ~/.ssh/
    • Drag and Drop
    • Emmet
    • Macro
    • ...

Extending the capabilies

You can easily extend to include tool you may need and have them ready
whenever you re-create your container. Just create a Dockerfile like:

FROM wernight/codiad
RUN apt update && apt install -y build-essential python

Now you can just build and use your new image:

$ docker build -t codiad .
$ docker run --rm -p 8080:80 codiad


  • 2016-06-29: Include docker and docker-compose to allow building stuff from within Codiad.
  • 2016-06-29: Makes latest based on Ubuntu due to some bugs and to allow extending; keep alpine as a branch.
  • 2016-06-24: Base on Alpine + S6 + Nginx + PHP-FPM.
  • 2016-06-23: Removed plug-ins and inlined this repos' init scripts.
  • 2016-06-22: Initial release based on the excellent codiac image
