Pattern: Dependency Update Bot

Status: seed Readiness target: RL2 private beta Primary owners: product repos Genesis family: Supply chain

Problem

Dependency updates become stale, risky, and manual when there is no repeatable intake and test path.

Context

Use this pattern for application dependencies, container base images, GitHub Actions, Helm charts, Terraform providers, and platform tools.

Forces

• Automated updates reduce known-vulnerability exposure.
• Update noise can overwhelm reviewers.
• Security updates need prioritization.
• Tests must catch compatibility breakage.

Solution

Use automated dependency update pull requests with grouping rules, security prioritization, test gates, review ownership, and release notes.

Verification

• Dependency inventory is covered by update automation.
• Security updates are surfaced with priority.
• Update PRs run relevant tests.
• Deferred updates have owner and reason.
