COSCUP x KCD Taiwan 2022 Kubernetes PR flow Step 0: Automation suggests reviewers and approvers for the PR - Choose at least two suggested reviewers, and request their reviews on the PR Step 1: Humans review the PR - Reviewers look for general code quality, correctness, sane software engineering, style, etc. - If the code changes look good to them, a reviewer types /lgtm in a PR comment or reviewOnce a - reviewer has /lgtm'ed, prow (@k8s-ci-robot) applies an lgtm label to the PR Step 2: Humans approve the PR - Approvers look for holistic acceptance criteria, including dependencies with other features, forwards/backwards compatibility, API and flag definitions, etc - If the code changes look good to them, an approver types /approve in a PR comment or reviewprow (@k8s-ci-robot) updates its comment in the PR to indicate which approvers still need to approve - Once all approvers (one from each of the previously identified OWNERS files) have approved, prow (@k8s-ci-robot) applies an approved label Step 3: Automation merges the PR - All required labels are present (eg: lgtm, approved) - Then the PR will automatically be merged 29
