Repository

The repository https://gitlab.eufus.psnc.pl/containerization/imas/imas-installer contains instructions on how to build the container by yourself using script. Instructions below are more in-depth if you wish to build more custom IMAS container.

Introduction

  • This document describes how to build a Docker image with IMAS environment
  • The build is divided into several steps, each in a separate executable file with sequential naming convention: 01-base, 02-ual, 03-kepler, 04-fc2k, 05-gui, 06-intel-mpi-mkl and 07-save
  • Steps 2, 3 and 4 require access to a private SSH key to query git://git.iter.org
  • The result of step 4 is a usable image with IMAS, Kepler and FC2K
  • Step 5 is optional, it adds on top of Step 4 the GUI libraries and configurations to work with the container via VNC (remote desktop)
  • Step 6 is optional, it adds Intel libraries
  • Step 7 exports the result of step 4 and 5 into image archives (these can be transferred and loaded by Docker daemon or uDocker executable)

...

  • You can build the image rootless when these requirements are met:

    • A kernel with support for User Namespaces (CONFIG_USER_NS) must be present

    • A sysctl setting must be present kernel.unprivileged_userns_clone = 1

    • Create /etc/subuid and /etc/subgid with the following content (replace LOGIN with a login of user able to build containers)

      LOGIN:100000:65536

Building procedure

Repository

  • The building procedure is available in a version-controlled repository:

    git clone ssh://git@git.iter.org/imex/imas-container.git
