Running Dagger Pipelines on Sourcehut
I was excited to get Dagger running on sourcehut this week because it combines a few of my favorite things. Dagger, of course, the place where I work. And sourcehut, a bad ass team of indie hackers, led by Drew DeVault on a mission to create a truly open home for open source projects on the web. It is an entire suite of services including git hosting, issue tracker, wiki, mailing list, static site hosting, and of course a fully functional CI build system.
While sourcehut provides a great general purpose CI build system, it does not yet have any caching provided by default. This means that for nontrivial projects you may find yourself spending a ton of time redownloading dependencies every time you run a build. This makes sourcehut the perfect fit for Dagger Cloud since it provides caching out of the box.
I attempted to get a simple POC up and running using the early release
of Dagger modules. I initially tried to get this working on the
alpine/latest image, but I ran into some roadblocks because Docker in
Docker was complaining about some networking permissions. I was happy to
see that this works pretty much out of the box using the provided
ubuntu/lts image.
All the code shared in this post is available in this demo repo.

Occupation and Preoccupation
Here’s Jony Ive in his Stripe interview: What we make stands testament to who we are. What we make describes our values. It describes our preoccupations. It describes beautiful succinctly our preoccupation. I’d never really noticed the connection between th…

As a journalist by training, I have what you might call an addiction to facts. I believe that there are things that are true and things that are not, and that we can determine one from the other through observation, rational thought, and meticulous resear…
