# Untrusted image
gh workflow run "FXCI - Azure" \
  --repo mozilla-platform-ops/worker-images \
  -f config=<CONFIG_NAME>

# Trusted image
gh workflow run "FXCI - Azure - Trusted" \
  --repo mozilla-platform-ops/worker-images \

# Get latest run for trusted
gh run list --repo mozilla-platform-ops/worker-images \
  --workflow "FXCI - Azure - Trusted" --limit 1 \
  --json databaseId,url,status,createdAt
