[Cloud9](https://github.com/c9/core) Cloud9 is a complete web based IDE with terminal access. This container is for running their core SDK locally and developing plugins.
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/).
Simply pulling `linuxserver/cloud9` 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 |
## Version Tags
This image provides various versions that are available via tags. `latest` tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.
| Tag | Description |
| :----: | --- |
| latest | Docker and Compose environment pre-installed |
| go | Basic Golang environment pre-installed |
| nodejs | Current stable NodeJS/NPM environment pre-installed |
| python | Current Python3 environment pre-installed |
| ruby | Current Ruby environment pre-installed |
## Usage
Here are some example snippets to help you get started creating a container.
Container 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.
| Parameter | Function |
| :----: | --- |
| `-p 8000` | The port for the Cloud9 web interface |
| `-e PUID=1000` | for UserID - see below for explanation |
| `-e PGID=1000` | for GroupID - see below for explanation |
| `-e TZ=Europe/London` | Specify a timezone to use EG Europe/London, this is required for Radarr |
| `-e GITURL=https://github.com/linuxserver/docker-cloud9.git` | Specify a git repo to checkout on first startup |
| `-v /code` | Optionally if you want to mount up a local folder of code instead of checking out |
| `-v /var/run/docker.sock` | Needed if you plan to use Docker or compose commands |
## 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:
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
* Update the image: `docker pull linuxserver/cloud9`
* Stop the running container: `docker stop cloud9`
* Delete the container: `docker rm cloud9`
* Recreate a new container with the same docker create parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
* Start the new container: `docker start cloud9`
* You can also remove the old dangling images: `docker image prune`
### Via Docker Compose
* Update all images: `docker-compose pull`
* or update a single image: `docker-compose pull cloud9`
* Let compose update all containers as necessary: `docker-compose up -d`
* or update a single container: `docker-compose up -d cloud9`
* You can also remove the old dangling images: `docker image prune`
### Via Watchtower auto-updater (especially useful if you don't remember the original parameters)
* Pull the latest image at its tag and replace it with the same env variables in one run:
**Note:** We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.
