Imagine I have a workflow with 5 steps.
Step 2 may or may not create a file as its output (which is then used as input to subsequent steps).
I'm sure there must be a simple way to do this yet I'm failing to figure out how.
I tried by making step 2 return non-zero exit code when no file is created and then using
when: "{{steps.step2.outputs.exitCode}} == 0" on step 3, but that still executes step 4 and 5 (not to mention marks step 2 as "failed")
So I'm out of ideas, any suggestions are greatly appreciated.
By default, a step that exits with a non-zero exit code fails the workflow.
I would suggest writing an output parameter to determine whether the workflow should continue.
- name: yourstep
container:
command: [sh, -c]
args: ["yourcommand; if [ -f /tmp/yourfile ]; then echo continue > /tmp/continue; fi"]
outputs:
parameters:
- name: continue
valueFrom:
default: "stop"
path: /tmp/continue
Alternatively, you can override the fail-on-nonzero-exitcode behavior with continueOn.
continueOn:
failed: true
I'd caution against continueOn.failed: true. If your command throws a non-zero exit code for an unexpected reason, the workflow won't fail like it should, and the bug might go un-noticed.
