This container provides a VNC-enabled container based on Ubuntu.
The container is meant to serve a basis for containerised X11 applications. It has the following features:
- Openbox minimal Window Manager
- Graphical login (not configured by default)
The container runs a VNC server on port 5900. This port has to be mapped for VNC clients to access it:
docker run -d -p 5900:5900 kramergroup/vnc-ubuntuOnce the container is running, point a VNC viewer to localhost:5900.
The behaviour of the container can be controlled through a number of environment variables.
| Name | Default | Description |
|---|---|---|
| GEOMETRY | 1600x900 | Display dimensions |
| RFBPORT | 5900 | The VNC server port |
| USERNAME | root | The default user username (will be created if needed) |
| USERID | auto | The UID of the default user |
A connecting VNC client will be presented with a login window for the first time only. Note that terminating the VNC connection is not sufficient to logout the user! There is no default user configured.
The usual useradd/passwd feature of linux is available. To add a user to a running container with name vnc-alpine use:
docker exec -it vnc-ubuntu adduser <username>The container uses the Openbox window manager. Openbox is lightweight and easy to configure (via xml files). Programs are started using a right-click, which produces a menu with options.
The container uses urxvt with a small number of extensions pre-installed. Awesome urxvt has a curated list of other useful extensions.
