[dependabot]

Bumps sigs.k8s.io/external-dns from 0.21.0 to 0.22.0.

Release notes

Sourced from sigs.k8s.io/external-dns's releases.

v0.22.0

General information

Action required before upgrade

• ⚠️ The default annotation prefix is now external-dns.kubernetes.io/ with no fallback (#6424)

  • 🚨 This change can delete all your DNS records.
  • ℹ️ You can either migrate your annotations or set --annotation-prefix=external-dns.alpha.kubernetes.io/.
  • ➡️ It's recommended to try this version with --dry-run=true & --policy=create-only.

• ⚠️ To avoid any unwanted DNS records deletion from the annotation prefix change, --policy is now required with no default (#6508).

Important

• ⚠️ CRD/API upgrades: Gateway API TLSRoute now uses v1, standard channel since Gateway API v1.5.0 (#6367). Ambassador Host now uses getambassador.io/v3alpha1 (#6482). Pi-hole v5 API is removed, v6+ only (#6406).
• ℹ️ On AWS, ownership TXT records for A ALIAS now use the a- prefix (#6523). Migration is automatic and ownership is preserved
  • Leftover cname- records can be cleaned with scripts/aws-cleanup-legacy-txt-records.py --alias-cname-cleanup.
• ℹ️ This release removes in-tree support for Akamai, Plural & Transip (#6485).
  • Users needing those providers can use a previous version of ExternalDNS or a webhook-based provider. Gandi is marked for removal (#6634).
• ℹ️ New: crd registry as an alternative to TXT (#5372)
• ℹ️ DNAME record support (#6553), and --rfc2136-axfr replacing the deprecated --rfc2136-tsig-axfr (#6598).

Changelog

Release

Release cycle

Currently we don't release regularly. Whenever we think it makes sense to release a new version we do it. You might want to ask in our Slack channel external-dns when the next release will come out.

Staging Release cycle

A new staging image is released weekly and can be found on the official staging registry.

There is a time lag between merging changes into the master branch and the subsequent creation of the staging image.

Example command to fetch 10 most recent staging images:

export EXT_DNS_VERSION="v0.22.0"
curl -sLk https://gcr.io/v2/k8s-staging-external-dns/external-dns/tags/list | jq | grep "$EXT_DNS_VERSION" | tail -n 10

Versioning convention

These are the conventions that we will be using for releases following 0.7.6:

• Patch version should be updated if we need to merge bugfixes, e.g. provider a does need a fix in order make updates working again. I would see updating or improving documentation here.

• Minor version should be updated if new features are implemented in existing providers or new provider get introduced.

• Major version should be upgraded if we introduce breaking changes.

Semantic Versioning Discipline

External-DNS follows semantic versioning principles:

• 0.x → pre-stable, APIs subject to change.
• 1.x → not yet considered.

Versioning & Releases External-DNS opts to stay within 0.x versioning scheme. We strive for stability, but reserve the right to introduce breaking changes in minor version bumps when necessary.

How to release a new image

Prerequisite

We use https://github.com/cli/cli to automate the release process. Please install it according to the official documentation.

You must be an official maintainer of the project to be able to do a release.
