git

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Options

Release version options based on https://github.com/git/git/releases

Defaults for build are

  • GIT_VERSION=2.17.0
  • LMOD_MODULE_DIR=/opt/apps/Linux

Other dependencies

None

Build

docker image

Build the docker image from the git/ directory

docker build -t lmod.git .

Lmod package files and Lua script

Generate the Lmod package files and Lua script by running the container with optional environment variable overrides for GIT_VERSION and LMOD_MODULE_DIR.

The output files will be saved to the directory mapped to the /output volume of the container. For clarity this should map to the version of the package being generated.

Example:

docker run --rm \
  -v $(pwd)/2.17.0:/output \
  -e GIT_VERSION=2.17.0 \
  -e LMOD_MODULE_DIR=/opt/apps/Linux \
  lmod.git

Upon completion the following files should be observed

$ ls -alh $(pwd)/2.17.0
-rw-r--r--  1 xxx  xxx   375B Apr 22 12:00 2.17.0.lua
-rw-r--r--  1 xxx  xxx    41M Apr 22 12:00 git-2.17.0.tar.gz

Install

The generated files should be placed into the target systems modules (/opt/apps/Linux) and modulefiles (/opt/apps/modulefiles/Linux) directories using the hierachy:

  • Modules: /opt/apps/Linux/git/git-2.17.0
  • Modulefiles: /opt/apps/modulefiles/Linux/git/2.17.0.lua

Example installation

  • Where modules and modulefiles directories are mapped to the target systems /opt/apps/Linux and /opt/apps/modulefiles/Linux directories respectively.
  • Assumes lmod-modules-centos repository is one level up for relative path commands.
mkdir -p modules/git
mkdir -p modulefiles/git
cp ../lmod-modules-centos/git/2.17.0/git-2.17.0.tar.gz \
  modules/git/git-2.17.0.tar.gz
cp ../lmod-modules-centos/git/2.17.0/2.17.0.lua \
  modulefiles/git/2.17.0.lua
cd modules/git
tar -xzf git-2.17.0.tar.gz
rm -f git-2.17.0.tar.gz
cd -

module avail

Once installed Lmod will show the module as:

$ module avail

-------- /opt/apps/modulefiles/Linux --------
   git/2.17.0
