By the way, I just launched my new thing today :) They say lightning never strikes twice, but you never know! I hope the plug is appropriate in this setting - apologies if not. https://dagger.io/blog/dagger-10-beta/

HN discussionI did make a bunch of money with Docker, something I am eternally grateful for. I did not start a band, but I did build a nice house, help my family etc. I still program everyday, working on my second startup, https://dagger.io (please forgive the plug). We have a very active discord if you want to come say hi.

HN discussion> GHA has "service containers", but unfortunately the feature is too basic to address real-world use cases: it assumes a container image can just … boot! … and only talk to the code via the network. Real world use cases often require serialized steps between the test & the dependencies, e.g., to create or init database dirs, set up certs, etc.) My biased recommendation is to write a custom Dagger function, and run i…

HN discussionI support the effort to build a platform-agnostic CI/CD pipeline solution, but I don't want it in the form of yet another platform. Rather it needs to be a protocol that any platform can tie in to. I'm especially wary since this is another VC-backed effort that will eventually need to be monetized in some shape or form. Additionally, as someone else here has already mentioned, my mind first went to Dagger, the depen…

HN discussionYes, I use Dagger, it's much more than building containers - Container based workflows are the same in CI and locally (you can run containers too), they become one-liners - Remote caching out of the box without extra steps - Multiple language SDKs, unlocks the DAG in BuildKit and containers, real reuse - Obfuscates secrets from your logs and agents. I've built an agent environment on Dagger, which also includes fork…

HN discussion> These alternatives are far more familiar and easier to work with. You can get most (but not all) of the benefits of NixOS with far less work. > Worse is better. There are some potential alternatives out there that seem inspired by Nix but which are less strict. I think a system that offers and manages Nix's purity but doesn't require it could end up the final winner some day. Shea Levy had some ideas for eventuall…

HN discussionI'd encourage anyone thinking of using make to look at alternatives. Make is great, but is quickly becomes a ball of duct-tape. Make works very well when you spend the time to express your dependency tree, but realistically that never happens and people tend to add hacks upon hacks for Makefiles. Not only that, but they don't scale well as your project adds more components, such as integration testing, documentation…

HN discussionFor CI specifically, you should IMO check out https://dagger.io . It abstracts and generalizes CI in exactly the way you need: repeatable, locally runnable, and also cacheable on remote servers. Write once, run anywhere CI - what you have locally will be _exactly_ what runs remotely.
