To keep to my cli-workflow, I make regular use of the GitHub CLI tool, gh on the command line. The manual specifies that you can specify the GH_HOST environment variable to direct it to a GitHub Enterprise server, but I don’t want to have to type that in every time. I added the following to my .bashrc: ghe() { GH_HOST="github.example.com" gh "$@"; } complete -o default -F __start_gh ghe Now, I can just run gh for public GitHub actions, and ghe for anything to do with example....

After using Markdown daily for many years, including all the content in this blog, I learned there was another way to do line breaks. I had always thought that the only way to do was to either have a blank line (which is not a line break, but a paragraph break) or add the <br /> HTML tag. I avoided the latter because I think it just plain looks ugly, and erases the elegance of using markdown, formatting without tags....

I regularly read the git blog and release notes, but did not see mention of this new feature in either. I was pleasantly surprised when I saw this tweet from James Ide: With the newest version of Git 2.37.0, you can run just "git push" to push new branches. No more "--set-upstream origin". Enable with: git config --global --add --bool push.autoSetupRemote true pic.twitter.com/1SzIqzvEFR — James Ide (@JI) July 12, 2022 This may be minor as it saves only a few keystrokes....

While updating some old code to add a small feature, I noticed a new error in the deployment where a puppet vcsrepo resource was failing. Error: /Stage[main]/Mirror::Crowdstrike/Mirror::Pymirror[crowdstrike]/Vcsrepo[/opt/crowdstrike-mirror]/ensure: change from 'absent' to 'latest' failed: Execution of 'git clone git://github.com/bowdoincollege/noc-crowdstrike-mirror.git /opt/crowdstrike-mirror' returned 128: Cloning into '/opt/crowdstrike-mirror'... fatal: unable to connect to github.com: github.com[0: 140.82.114.4]: errno=Connection timed out I logged into the box and ran the command directly to confirm. p-mirror-a:/opt/crowdstrike-mirror$ git fetch origin fatal: unable to connect to github....

By default, a Terraform Cloud remote run will copy the entire source repository to the TFC runner before it runs the plan. If there are lots of files in the repository that aren’t needed by Terraform, this can take a long time. Using the .terraformignore file can significantly reduce the time for TFC to prepare a remote plan. A common pattern is to have a terraform/ subdirectory in a repository to deploy the infrastructure that supports the application/service/code in the repository itself....

A few times in the past, I’ve had the need to take a subdirectory of an existing repository and move it to a new repository, while preserving history. I always had to look up the syntax for git filter-branch to do this; it worked, but wasn’t very straightforward or easy to remember. At some point, a subtree split command was added to git that makes this process much simpler. My real-world use case was in the migration and modernization of our puppet installation....

We make heavy use of puppet environments in our workflow. Using r10k, git branches are magically mapped to environments. This allows a process where anyone one the team can individually work on a new feature or change, and then we can collaborate and review/revise/test in a controlled manner. We can rebase to the production branch, and use the diff output as part of our change-management documentation. Once the change is merged, however, sometimes the original branch is not deleted....
