A pre-push git hook that notify Amazon Chime group

pre-push

#!/bin/sh

branch="$(git rev-parse --abbrev-ref HEAD)"

# get computer name to append in Chime message
username=$USER

# a branch name where you want to prevent git push. In this case, it's "master"
if [ "$branch" = "master" ]; then
  echo "You can't commit directly to '"${branch}"' branch" # webstorm or intellij will show this as popup
  curl -X POST "<Chime-Webhook-URL>" -H "Content-Type:application/json" --data '{"Content": "@All 🚧  '@"${username}"' trying to push code to '"${branch}"'. \n Please note that commit is not blocked but it is discouraged to push code directly to '"${branch}"'."}'
  exit 1 # if you remove this line then it won't block push but send message to group and on command line
fi


# Things you need to do - 
# 1. Copy above code
# 2. Go to your project/.git/hooks
# 3. Copy pre-push.sample and rename it to pre-push
# 4. Paste the above code
# 5. Make this file executable - $ chmod +x .git/hooks/pre-commit
# 6. Voila! Now you will see your push is failing in "master" branch
# 7. If you use Amazon Chime then create a webhook URL and replace the in cURL or add code which sends message to Slack or 
# your preferred communication channel

Great! How do I allow this to a specific user?

You can use username variable and put a if condition to match that user.
It will then work for that specific user only.

Thanks a lot for this 👍

Thanks a lot, this really helps me in sorting out my mistakes

Hi, thanks for this gist.
In your hook, you're getting branch but I wanted to also check which tags are available. Is there any way to achieve this?
Thanks in advance!

I would suggest replacing the hardcoded master branch name with the default branch. Reason being that many repos made the switch to rename master to main or something else completely.

#!/bin/sh

protected_branch="$(git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@')"
branch="$(git rev-parse --abbrev-ref HEAD)"

# get computer name to append in Chime message
username=$USER

# a branch name where you want to prevent git push. In this case, it's "master"
if [ "$branch" = "$protected_branch" ]; then
  echo "You can't commit directly to '"${branch}"' branch" # webstorm or intellij will show this as popup
  curl -X POST "<Chime-Webhook-URL>" -H "Content-Type:application/json" --data '{"Content": "@All 🚧  '@"${username}"' trying to push code to '"${branch}"'. \n Please note that commit is not blocked but it is discouraged to push code directly to '"${branch}"'."}'
  exit 1 # if you remove this line then it won't block push but send message to group and on command line
