Automate Git push

If you would like to automate Git push, you can do this with a Git post commit hook

  1. Create the post-commit file

    Code Block
    languagebash
    themeRDark
    OMD[mysite]:~$ vi ~/etc/check_mk/.git/hooks/post-commit

    .

  2. Add the following

    Code Block
    languagebash
    themeRDark
    title~/etc/check_mk/.git/hooks/post-commit
    #!/bin/sh
git push -u origin mybranchname

    .

  3. Save the file
    .

  4. Make the file executable

    Code Block
    languagebash
    themeRDark
    OMD[mysite]:~$ chmod +x ~/etc/check_mk/.git/hooks/post-commit
