# NOVNC-BASE
A desktop environment with sound in docker.
A desktop environment with sound in docker
Can be used as a base file for application specific containers.
- `thomasloven/novnc-ubuntu`
- `thomasloven/novnc-debuan`
- `thomasloven/novnc-alpine`
To just get a desktop environment at `http://localhost:8080`:
```bash
docker run --rm -p 8080:8080 thomasloven/novnc-ubuntu
```
Or used as a base for specific applications:
E.g:
```dockerfile
FROM thomasloven/novnc-ubuntu
FROM thomasloven/novnc-base
RUN sudo apt-get update \
&& DEBIAN_FRONTEND=noninteractive \
@ -26,12 +16,6 @@ RUN sudo apt-get update \
CMD ["blender"]
```
See more examples in `apps/`.
The container will run as user `$USERNAME` (default `novnc`) with uid `${UUID}` (default `1000`) and group id `${GUID}` (default `1000`).
The user has sudo privileges with no password(!).
### Bonus functionality - dotfiles installation.
If the environment variable `DOTFILES_REPO` is set, the container will `git
clone` that into `~/dotfiles` and then run `~/dotfiles/install.sh` if it
