Checklist Gate

Stop on Failure

A release script should stop when a required check fails. This capstone example counts ready checks and records the first blocking step.

Program

Play the script to choose whether the release checklist passes or stops at tests.

release_checklist_gate.sh 
#!/usr/bin/env bash

failed_step=
checks="lint tests build publish"
ready=0
for check in $checks; do
    if [[ "$check" == "$failed_step" ]]; then
        status="blocked:$check"
        break
    fi
    ready=$((ready + 1))
done
if [[ "$failed_step" == "none" ]]; then
    status="ready"
fi
echo "ready=$ready status=$status"
