CI/CD platform with customizable API triggers?
I'm wondering if there are CI/CD platforms that do not force you to connect & activate repos/orgs before doing builds?
In short - I need self-hosted server, that will receive triggers via custom API calls and start building/doing something in containers based on pipeline config (YAML etc.).
Trigger can be a webhook from self-hosted git server after pushed commit (from any repo & any user on server, not only activated), or API call from Cloud Function to do something in container and store artefact in Cloud Storage, or evaluate some expressions etc etc.
CI/CD tools (like Drone, for example) don't allow that since they focus on git only + they force users to connect all needed repos first, before triggers may start working.
In my case that's not an option because I manage a git server where there are dozens of users that don't belong to any org and I don't want to force them to manually enable & activate their repos...
The closest platform to my needs seems to be Concourse CI.... Because it can work just as automated builder with nice pipeline syntax.
But maybe there are better ones?
