This is a bash script that posts a message into your Slack channel when changes are pushed.
Hook this script into post-receive for your git repositories.
Note: some git repositories may be "bare". You'll know if your repo is bare or not by checking for a .git folder where your repo lives.
Download git-slack-hook onto the server which hosts your git repo.
For bare repos, copy/rename it as /path/to/your/repo/hooks/post-receive.
For normal/non-bare repos, copy/rename it as /path/to/your/repo/.git/hooks/post-receive.
Finally, chmod +x post-receive to allow the script to be executed.
Add an Incoming WebHooks integration in your Slack by going to e.g.
https://my.slack.com/services/new/incoming-webhook
Make note of the webhook URL.
git config hooks.slack.webhook-url 'https://hooks.slack.com/services/...'
git config hooks.slack.channel '#general'
'#channelname' - post to channel
'@username' - direct message to user
'groupname' - post to group
Specifies a channel to post in Slack instead of the default.
git config hooks.slack.username 'git'
Specifies a username to post as. If not specified, the default name incoming-webhook will be used.
git config hooks.slack.icon-url 'https://example.com/icon.png'
Specifies an icon to display in Slack instead of the default.
git config hooks.slack.icon-emoji ':twisted_rightwards_arrows:'
Specifies an emoji icon to display in Slack instead of the default.
git config hooks.slack.repo-nice-name 'My Awesome Repository'
Specifies a repository nice name that will be shown in messages.
git config hooks.slack.show-only-last-commit true
Specifies whether you want to show only the last commit (or all) when pushing multiple commits.
git config hooks.slack.show-full-commit true
Specifies whether you want to show the body of the commit message as well as the title.
git config hooks.slack.branch-regexp regexp
Specifies if you want to send only certain branches
When the following parameters are set, revision hashes will be turned into links to a web view of your repository.
git config hooks.slack.repos-root '/path/to/repos'
git config hooks.slack.changeset-url-pattern 'http://yourserver/%repo_path%/changeset/%rev_hash%'
For example, if your repository is in /usr/local/repos/myrepo, set repos_root to /usr/local/repos/ and set changeset_url_pattern to http://yourserver/%repo_path%/changeset/%rev_hash% or whatever.
Links can also be created that summarize a list of commits:
git config hooks.slack.compare-url-pattern 'http://yourserver/%repo_path%/compare/%old_rev_hash%..%new_rev_hash%'
