Pulumi Upgrade Provider

Overview

Run upgrade-provider, fix known failures, and rerun until success. Keep git operations read-only in the repo; the tool owns branch/commit/PR state.

Run Loop

1. Create output directory:

mkdir -p .pulumi

2. Run from repo root:

upgrade-provider $ORG/$REPO --repo-path . > .pulumi/upgrade-provider-stdout.txt 2> /dev/null

3. Wait for completion (can take up to 10 minutes).
4. Check for errors by scanning .pulumi/upgrade-provider-stdout.txt lines starting with error: .
5. If failed, fix using this skill's references/upgrade-provider-errors.md (from the skill folder, not the repo), then rerun.
6. If a fix requires creating/amending/removing/rebasing patches, use the upstream-patches skill for the patch workflow.
7. If you fixed a conflict, report exact edits (file paths + concrete changes or preserved intent).
8. If the upgrade changed patches, run ./scripts/upstream.sh checkout and review applied upstream commits:
   • List commit SHAs/titles from upstream.
   • Summarize the intent of each commit in plain language.
   • Call out any behavioral changes or risks.
9. On success, proceed to Post-run Tasks.

When to Stop and Report Failure

Stop iterating and report failure if any of these conditions are met:

1. Command not found (exit code 127): The upgrade-provider tool is not in PATH.
2. Same error 3 times: You've attempted to fix the same error 3 times without success.
3. Unknown error pattern: The error is not covered in references/upgrade-provider-errors.md and you cannot determine a safe fix.
4. Requires human judgment: The fix needs user input, such as:
   • Choosing between multiple valid approaches
   • Breaking changes that affect public API
   • Deprecation strategies
   • Architectural decisions about module organization

When stopping, report:

1. The error(s) encountered.
2. What fixes were attempted (with file paths and changes).
3. Why human intervention is needed.
4. Any partial progress.

Post-run Tasks

The tool creates a PR on successful upgrade.

1. MUST fetch the PR URL for the current branch using read-only commands:

gh pr view --json url --jq .url || gh pr list --head "$(git branch --show-current)" --json url --jq '.[0].url'

2. MUST append a "Fixes applied to unblock upgrade" section to the existing PR body if any fixes were applied (do not overwrite):

repo=$(gh repo view --json nameWithOwner --jq .nameWithOwner)
pr_number=$(gh pr view --json number --jq .number)
gh pr view --json body --jq .body > /tmp/pr_body.txt

cat <<'EOF' >> /tmp/pr_body.txt

---

### Fixes applied to unblock upgrade

- <list concrete unblocker edits here, with file paths and intent>
EOF

gh api -X PATCH "repos/$repo/pulls/$pr_number" --raw-field body="$(cat /tmp/pr_body.txt)"

Use REST (gh api) instead of gh pr edit to avoid GraphQL project-card errors. Keep existing body content; only append.

Notes

• git rebase --continue --no-edit is not supported in older git versions. Use git rebase --continue and accept the existing commit message.
• To avoid the editor prompt during git rebase --continue, run it with GIT_EDITOR=true (or GIT_EDITOR=:).

Guardrails

• Never commit, push, or create branches manually; only run read-only git commands.
• ./scripts/upstream.sh checkout|rebase|check_in are allowed because the tool manages git state.
• Do not stash changes; the tool manages git state.

References

• Use this skill's references/upgrade-provider-errors.md (from the skill folder, not the repo) for patch conflict and new module mapping fixes.
