Task with loop in Argo workflow

Question

I want to introduce a for loop in a workflow that consists of 2 individual tasks. The second will be dependent on the first. Each one should use different templates. The second should iterate with {{item}}. For each iteration I want to know if the default is to execute only the second task or it will re-execute the whole flow?

Answer 1

To repeat the second step only, use withItems/withParameter (there is no withArtifact, though you can get the same behavior with data). These loops repeat the specific step they are mentioned in for the specified items/parameter only.
