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!)

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

Features

• Add support for JSON logging format by @erikgb in #354

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

Full Changelog: v0.9.0...v0.9.1

v0.9.0

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

v0.9.0 contains a bunch of improvements and once again the awesome trust-manager community played a huge role!

Inclusions to note are:

• We fixed a bug (#296) which broke passwordless PKCS#12 files when read by Java.
  • It's possible that this could have an effect on non-Java platforms, but in testing it seemed safe for both Go and Java
• We added support for the s390x architecture for trust-manager!
• We added a crds.keep option to reduce the risk of losing important data when uninstalling trust-manager
• We fixed an issue with certificate deduplication when certs were present in multiple sources

As always, please report any issues either here in the repo, in a cert-manager meeting or on Slack!

Happy bundling!
