- What ports are exposed?
- What volumes can be be used?
- What Ubuntu version is installed?
- Is running in foreground supported?
Containers created from the images expose the following TCP ports:
- port 5901 is used for access via a VNC viewer (e.g. TigerVNC or TightVNC)
- port 6901 is used for access via a web browser with HTML5 support (noVNC)
The images do not create or use any external volumes by default. However, the following folders make good mounting points:
- /home/headless/Documents/
- /home/headless/Downloads/
- /home/headless/Music/
- /home/headless/Pictures/
- /home/headless/Public/
- /home/headless/Templates/
- /home/headless/Videos/
Both named volumes and bind mounts can be used. More about volumes can be found in Docker documentation.
Firefox profiles on mounted volumes will survive container destruction.
You can check the actual Ubuntu version installed in the container by typing the following command into the terminal window:
lsb_release -aThe output will look similar to this:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic
Yes, containers created from this image can be used running in foreground (interactively). They even support several start-up options. Check the HOWTO page for more information.
