Use the same code for Gitlab / Github Action with Dagger.io

[lavish wadi]

Hi everyone, I'm new to the server !
Is it possible to make a Gitlab CI/CD pipeline (build / push) work on Gitlab and Github Action (identical code in both cases) using the Dagger.io tool ?

Hi @lavish wadi 👋 Yes that's exactly the power of Dagger! The idea is that you can write the code once, and run the same dagger call anywhere and it will run the same way

Okay, but how do you include the Dagger.io part in the Gitlab CI /CD pipeline ? Do I have to rewrite “everything” in Node, Go or Python ?

Usually people "daggerize" their pipelines piece by piece. For example if there's a particularly complicated integration test step you could start with that and keep the rest of the existing pipeline the same. Here's an example of how to run dagger in gitlab https://docs.dagger.io/integrations/734201/gitlab

Justement, j'ai déjà lu cette documentation, mais certains points sont encore un peu "obscur" pour moi, et il n'y a pas énormément de documentation sur le sujet...
