# 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 registry.ict.inaf.it/exact/swc/basicdesktop:v0.3.0 or use tham as base containers for your own ones: FROM registry.ict.inaf.it/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
