I do devops at work and my experience is that really any CI/CD system works, they all have enough features to do what you want. They all fundamentally just run scripts on boxes. Therefore, I say pick the easiest one, likely the one that is built into whatever Git system you are using.

Try to keep your pipelines simple-ish when you can, they almost never need to be that complicated. 95% of the time it’s just running a command or two. If a pipeline needs to do something complex, I’d recommend writing that script into the Git repo and calling it, rather than having a CI job that is 100 lines long.

Mind sharing what service you use for it? Paid or free?
