Flux Image Auto Quick Fix - ImageUpdateAutomation

Flux ImageUpdateAutomation automatically commits image version updates to git repositories. Misconfigured automation causes failed commits or incorrect image updates. This guide covers the fix.

Quick Fix

Wrong

apiVersion: image.toolkit.fluxcd.io/v1beta2
kind: ImageUpdateAutomation
metadata:
  name: flux-system
spec:
  interval: 30m
  sourceRef:
    kind: GitRepository
    name: flux-system

The issue: no git spec with commit configuration, no checkout branch specified, and no push branch. Automation creates no commits because it lacks git configuration.

Right

apiVersion: image.toolkit.fluxcd.io/v1beta2
kind: ImageUpdateAutomation
metadata:
  name: flux-system
spec:
  interval: 30m
  sourceRef:
    kind: GitRepository
    name: flux-system
  git:
    checkout:
      ref:
        branch: main
    commit:
      author:
        name: flux-bot
        email: flux@example.com
      messageTemplate: "chore: update image tags"
    push:
      branch: main

# Expected output after applying the fix
# ImageUpdateAutomation checks main branch every 30m
# When image policy selects new tag, commit is created
# Commit message: "chore: update image tags"
# Changes pushed to main branch

Prevention

• Always configure git.checkout.ref.branch and git.push.branch
• Set meaningful commit.messageTemplate
• Configure commit author for git attribution
• Ensure the git authentication secret has write permissions
• Use image policy markers in YAML with format # {"$imagepolicy": "ns:name"}
