Application Setup

Access the webui at http://your-ip:8000, for more information check out here.


To help you get started creating a container from this image you can either use docker-compose or the docker cli.

version: "2.1"
    container_name: cloud9
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - GITURL= #optional
      - USERNAME= #optional
      - PASSWORD= #optional
      - /path/to/your/code:/code #optional
      - /var/run/docker.sock:/var/run/docker.sock #optional
      - 8000:8000
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=cloud9 \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e GITURL= `#optional` \
  -e USERNAME= `#optional` \
  -e PASSWORD= `#optional` \
  -p 8000:8000 \
  -v /path/to/your/code:/code `#optional` \
  -v /var/run/docker.sock:/var/run/docker.sock `#optional` \
  --restart unless-stopped \


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
8000 The port for the Cloud9 web interface

Environment Variables (-e)

Env Function
PUID=1000 for UserID - see below for explanation
PGID=1000 for GroupID - see below for explanation
TZ=Europe/London Specify a timezone to use EG Europe/London
GITURL= Specify a git repo to checkout on first startup
USERNAME= Optionally specify a username for http auth
PASSWORD= Optionally specify a password for http auth (if USERNAME and PASSWORD are not set, there will be no http auth)

Volume Mappings (-v)

Volume Function
/code Optionally if you want to mount up a local folder of code instead of checking out
/var/run/docker.sock Needed if you plan to use Docker or compose commands

Miscellaneous Options

Parameter Function

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)

Docker Mods

Docker Mods Docker Universal 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 cloud9 /bin/bash
  • To monitor the logs of the container in realtime:
  • docker logs -f cloud9
  • Container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' cloud9
  • Image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}'
