Containers

Various Docker and Singularity containers.

Hierarchy

• Base
  • X11Web
    • MinimalDesktop
      • BasicDesktop
        • ViaLacteaVisualAnalytics
  • JupyterNotebook
  • SSH
    • XCalc

Interfaces

The container starts by automatically exposing their interfaces:

• The containers based on the X11Web container (as the desktops) expose a web-based VNC client (KasmVNC) on port 8590

• The JupyterNotebook container expose the Notebook server on port 8888

• The SSH container expose the OpenSSH server on port 22

All the containers support changing the default port using the BASE_PORT environment variable.

Usage

You can eithe directly run the containers, e.g.:

docker run -p8590:8590 git.ia2.inaf.it:5050/exact/swc/basicdesktop:v0.3.0

or use tham as base containers for your own ones:

FROM git.ia2.inaf.it:5050/exact/swc/basicdesktop:v0.3.0

Supported engines

These containers are built to be supported by nearly any container engine. These include:

• Docker
• Podman (rootful and rootless)
• Singularity

However, beware some permission errors which may arise after extending them and installing extra software, in particular with Singularity. You can add a line like this at the end of your Dockerfile to be sure the home folder is always set as writable by anyone (required for these containers to work with Singularity):

# Fix home permissions
RUN chmod 777 /home
