git operations using chef recipe

Question

I would like to perform the below steps using chef recipe;

git add file1.txt
git commit -m "file1.txt"
git push origin master

I have tried using the below script, but I'm stuck with the next steps, I couldn't find enough details in chef.io details regarding git operations. How do we use git add and git push in the chef recipe. Appreciated any help here

git "/home/file1.txt" do
  repository "git://gitlab.com/kimkev/prism_systems.git"
  revision "master"
  action :sync
end
