cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

The cert-manager 1.16 release includes: new Helm chart features, more Prometheus metrics, memory optimizations, and various improvements and bug fixes for the ACME issuer and Venafi Issuer.

📖 Read the complete 1.16 release notes before upgrading.

📜Changes since v1.16.0

Bug or Regression

• BUGFIX: Helm schema validation: the new schema validation was too strict for the "global" section. Since the global section is shared across all charts and sub-charts, we must also allow unknown fields. (#​7348, @inteon)
• BUGFIX: Helm will now accept percentages for the podDisruptionBudget.minAvailable and podDisruptionBudget.maxAvailable values. (#​7345, @inteon)
• Helm: allow enabled to be set as a value to toggle cert-manager as a dependency. (#​7356, @inteon)
• BUGFIX: A change in v1.16.0 caused cert-manager's ACME ClusterIssuer to look in the wrong namespace for resources required for the issuance (e.g. credential Secrets). This is now fixed in v1.16.1. (#​7342, @inteon)

v1.16.0

Compare Source

v1.15.4

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

This patch release of cert-manager 1.15 makes several changes to how PEM input is validated, adding maximum sizes appropriate to the type of PEM data which is being parsed.

This is to prevent an unacceptable slow-down in parsing specially crafted PEM data. The issue was found by Google's OSS-Fuzz project.

The issue is low severity; to exploit the PEM issue would require privileged access which would likely allow Denial-of-Service through other methods.

Note also that since most PEM data parsed by cert-manager comes from ConfigMap or Secret resources which have a max size limit of approximately 1MB, it's difficult to force cert-manager to parse large amounts of PEM data.

Further information is available in GHSA-r4pg-vg54-wxx4

In addition, the version of Go used to build cert-manager 1.15 was updated along with the base images, and a Route53 bug fix was backported.

Bug or Regression

• Bugfix: Prevent aggressive Route53 retries caused by STS authentication failures by removing the Amazon Request ID from STS errors. (#​7261, @​cert-manager-bot)
• Set a maximum size for PEM inputs which cert-manager will accept to remove possibility of taking a long time to process an input (#​7402, @​SgtCoDFish)

Other (Cleanup or Flake)

v1.15.0

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

cert-manager 1.15 promotes several features to beta, including GatewayAPI support (ExperimentalGatewayAPISupport), the ability to provide a subject in the Certificate that will be used literally in the CertificateSigningRequest (LiteralCertificateSubject) and the outputting of additional certificate formats (AdditionalCertificateOutputFormats).

[!NOTE]

The cmctl binary have been moved to https://github.com/cert-manager/cmctl/releases.
For the startupapicheck Job you should update references to point at quay.io/jetstack/cert-manager-startupapicheck

[!NOTE]

From this release, the Helm chart will no longer uninstall the CRDs when the chart is uninstalled. If you want the CRDs to be removed on uninstall use crds.keep=false when installing the Helm chart.

• During the release of v1.14.0, the Helm chart for this version was found to use the wrong OCI image for the cainjector Deployment,
  which caused the Helm installation to fail.
  In order to complete the release, the cert-manager team have manually updated the Helm chart for this version,
  which contains all the Helm chart fixes which are in v1.14.1.
• A bug in cmctl namespace detection prevents it being used as a startupapicheck image in namespaces other than cert-manager.
• A bug in cmctl causes cmctl experimental install to panic.

🔧 Breaking Changes

The startupapicheck job uses a new OCI image called "startupapicheck", instead of the ctl image.
If you run in an environment in which images cannot be pulled, be sure to include the new image.

The KeyUsage and BasicConstraints extensions will now be encoded as critical in the CertificateRequest's CSR blob.

🗺️ Major Themes

New X.509 Features

The cert-manager Certificate resource now allows you to configure a subset of "Other Name" SANs,
which are described in the Subject Alternative Name section of RFC 5280 (on page 37).

We specifically support any otherName type with a UTF-8 value, such as the User Principal Name or sAMAccountName.
These are useful when issuing unique certificates for authenticating with LDAP systems such as Microsoft Active Directory.
For example you can create certificates with this block in the spec:

  otherNames:
    - oid: 1.3.6.1.4.1.311.20.2.3 # UPN OID
      utf8Value: upn@domain.local

The feature is still in alpha stage and requires you to enable the OtherName feature flag in the controller and webhook components.

New CA certificate Features

You can now specify the X.509 v3 Authority Information Accessors extension,
with URLs for certificates issued by the CA issuer.

Users can now use name constraints in CA certificates.
To know more details on name constraints check out RFC section https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.10

Security

An ongoing security audit of the cert-manager code revealed some weaknesses which we have addressed in this release,
such as using more secure default settings in the HTTP servers that serve metrics, healthz and pprof endpoints.
This will help mitigate denial-of-service attacks against those important services.

All the cert-manager containers are now configured with read only root file system by default,
to prevent unexpected changes to the file system of the OCI image.

And it is now possible to configure the metrics server to use HTTPS rather than HTTP,
so that clients can verify the identity of the metrics server.

Other

The liveness probe of the cert-manager controller Pod is now enabled by default.

There is a new option .spec.keystores.pkcs12.algorithms to specify encryption and MAC algorithms for PKCS.

Feature

• ACME challenge solver Pod for HTTP01 will get a default annotation of "cluster-autoscaler.kubernetes.io/safe-to-evict": "true". You can provide an annotation of "cluster-autoscaler.kubernetes.io/safe-to-evict": "false" in your podTemplate if you don't like this. (#​6349, @​jsoref)
• Added a clock skew detector liveness probe that will force a restart in case we detect a skew between the internal monotonic clock and the system clock of more than 5 minutes.
  Also, the controller's liveness probe is now enabled by default. (#​6328, @​inteon)

• GHSA-vgf6-pvf4-34rq: The webhook server now returns HTTP error 413 (Content Too Large) for requests with body size >= 3MiB. This is to mitigate DoS attacks that attempt to crash the webhook process by sending large requests that exceed the available memory.
  The webhook server now returns HTTP error 400 (Bad Request) if the request contains an empty body.
  The webhook server now returns HTTP error 500 (Internal Server Error) rather than crashing, if the code panics while handling a request. (#​6498, @​inteon)
