Today’s lesson is on tagging and versions. I wanted to be able to automatically increment the version number of a node project when I push to master, and have that tag be used when building and pushing the updated Docker image.
My idea was that I’d change the package file manually, push it up, get Circle to read that and tag accordingly.
Turns out that reading the current version number isn’t really a thing in either
yarn, unless you
want to start using grep.
Instead, I went with using
patch and a read/write
deployment key to get those changes back into github.
Not quite there yet, as this has led to an infinite loops of pushing to master, getting notified of a change, incrementing the patch number, pushing to master, and so on.
Luckily, there is a very handy option to skip a build. All is well again.
