v0.13.0

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

v0.13.0 is a minor release to include a swathe of dependency updates, refactors and a few new features.

Among the new features is the new optional includeAllKeys field for Secret and ConfigMap sources, by @juliocamarero. Previously, these sources required users to specify an indvidual key to include in the resulting bundle. With this new field, you can request that all keys be included instead. Note that Secret sources of kubernetes.io/tls type are not eligible for use with includeAllKeys, to avoid trust-manager reading a private key.

In addition, @arsenalzp landed a great PR which cleans up handling of certificates within trust-manager, reducing the number of encode/decode operations done during a bundle reconcile.

What's Changed

• Support for including all certificates from a secret/configMap in bundle source by @juliocamarero in #460
• Introduce certificate pool structure and remove multiple encode/decode process by @arsenalzp in #375
• Fix example of topologySpreadConstraints to reference trust-manager by @SgtCoDFish in #401

• fix: don't error if source selector selects no sources by @erikgb in #432
• ci: fix new copyloopvar lint errors by @erikgb in #445
• test: add tests for truststore deterministic by @erikgb in #443

Refactoring

• refactor: fix name and import alias collisions by @erikgb in #412
• refactor: dedicated target data struct by @erikgb in #415
• refactor: move function for creating managed field entries by @erikgb in #413
• refactor: use NamespacedName instead of positional name/namespace by @erikgb in #435
• refactor: reduce duplication in sync target functions by @erikgb in #436

Full Changelog: v0.12.0...v0.13.0

v0.12.0

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

v0.12.0 includes a variety of Helm chart improvements, notably including the ability to install trust-manager without having first installed cert-manager!

Overview

Standalone trust-manager

Previously, trust-manager required that cert-manager was installed for generating the trust-manager webhook certificate. cert-manager's cainjector was used to inject this webhook cert into the Kubernetes webhook resource.

Some users wanted to be able to install trust-manager standalone, and now this is possible thanks to Helm's inbuilt support for generating certificates. We'd like to note that relying on Helm for this functionality isn't likely to be the best way to run in production - we'd strongly suggest that running with cert-manager is the way to go, since that will handle cert rotation and be much easier to administer.

Still, for any user who wants to simply run trust-manager, that's now possible:

helm upgrade trust-manager jetstack/trust-manager \
  --install \
  --namespace cert-manager \
  --wait \
  --set app.webhook.tls.helmCert.enabled=true

Other Helm Improvements

There are even more improvements to the Helm chart:

1. Support for configuring a dual stack service for the webhook (Thanks @M0NsTeRRR!)
2. More configurability of trust-manager's leader-election including duration and deadline (Thanks @jabdoa2!)

What's Changed

New Features

• Add support for generating certificates with helm by @SgtCoDFish in #157
• feat(helm): dual-stack cluster service configuration by @M0NsTeRRR in #337
• Add flags to configure LeaseDuration and RenewDeadline by @jabdoa2 in #385
• Expose leader election leaseDuration and renewDeadline in helm chart by @jabdoa2 in #388

Refactors

• refactor: simplify SSA patch calls by @erikgb in #393
• refactor: move default truststore passwords to API by @erikgb in #394
• refactor: extract truststore encoding to internal package by @erikgb in #396

• @M0NsTeRRR made their first contribution in #337

v0.11.1

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

What's Changed

• Bump sigs.k8s.io/controller-runtime from 0.18.3 to 0.18.4 in the all group by @dependabot in #369
• refactor: split bundle sync code into source and target by @erikgb in #370
• Bump the all group across 1 directory with 7 updates by @dependabot in #374
• refactor: build bundle data from relevant spec by @erikgb in #377
• Sort certificates in bundles to ensure deterministic behaviour by @jabdoa2 in #380

v0.11.0

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

v0.11.0 includes support for JSON logging, as well as some bug fixes and code quality improvements which have been made since the release of trust-manager v0.10.0

Notably, this release re-adds the s390x architecture which was missing in v0.10.0 and v0.10.1 and enables several linters to ensure the codebase remains at a high level of quality.

Feature Overview: JSON Logging

Prolific contributor @erikgb added support for JSON logging in trust-manager in #354 🚀

JSON logging can be enabled through the new app.logFormat Helm value which defaults to text but can be set to json.

$ helm upgrade trust-manager jetstack/trust-manager \
  --set app.logFormat=json \
  --install \
  --namespace cert-manager \
  --wait

$ kubectl logs -n cert-manager trust-manager-xxxxx
{"time":"2024-06-03T14:05:12.468612847Z","level":"INFO","msg":"successfully loaded default package from filesystem","logger":"trust/bundle","path":"/packages/cert-manager-package-debian.json"}
...

Log Level Parsing

v0.11.0 also changes how log levels are parsed when passed in to trust-manager.

Previously, non-numeric log levels would be silently ignored, so if you set a log level of "v5" rather than "5", the setting would not take effect and the log level would default to 1. Now, log levels must be valid integers and trust-manager will fail to start if a log level is invalid.

This change will help to catch configuration errors.

What's Changed

v0.10.2

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

The release of v0.10.2 was abandoned as the v0.10.2 tag was accidentally created containing changes which were larger than the scope of a patch release.

It will be replaced with v0.11.0

v0.10.1

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

This patch release fixes a bug in the trust-manager build process causing it to be build with an out-of-date go version (1.22.0), instead of the latest Go version available at the time (1.22.3).

Warning

trust-manager v0.10.1 does not include images for s390x. This was an oversight arising from the migration to makefile-modules.
This will be fixed in trust-manager v0.11.0

Full Changelog: v0.10.0...v0.10.1

v0.10.0

trust-manager is the easiest way to manage security-critical TLS trust bundles in Kubernetes and OpenShift clusters.

This release is be the first trust-manager release that uses Makefile modules. Apart from that change, this release includes a lot of version bumps and some small bug fixes.

Warning

There was a bug with the release of trust-manager v0.10.0 which meant it was built with go 1.22.0 rather than the latest Go version available at the time (1.22.3).
This was fixed in trust-manager v0.10.1 and v0.11.0+

Warning

trust-manager v0.10.0 does not include images for s390x. This was an oversight arising from the migration to makefile-modules.
This will be fixed in trust-manager v0.11.0
