v6.17.0

Released: June 11, 2025

GitLab has been updated to v18.0. See GitLab's guide to breaking changes for full details. Note particularly:
- Support for PostgreSQL 15 is removed in GitLab v18.0. (PostgreSQL 16 is configured with our GitLab RDS IaC module, so no action should be necessary if using up-to-date IaC.)
- The CI_JOB_TOKEN "Limit access from this project" option for has been removed after being deprecated in GitLab v16.0.
Values for the upstream Kyverno Helm chart have been refactored, so overrides which were previously defined under .kyverno.values should be moved to .kyverno.values.kyverno instead. The kyvernoPolicies values are not impacted by this change.
Values for the upstream Metrics-server Helm chart have been refactored, so overrides which were previously defined under .addons.metricsServer.values should be moved to .addons.metricsServer.values.upstream.
IaC: The default_metadata_options.http_tokens variable for the eks-cluster module now defaults to required instead of optional, disabling IMDSv1. This change will cause a node group rotation due to the updated launch template.
- If IMDSv1 is required, it can be enabled by setting the following in your env.hcl:
```
locals {
  cluster_inputs = {
    default_metadata_options = {
      http_tokens                 = "optional"
      http_put_response_hop_limit = 2
      instance_metadata_tags      = "disabled"
      http_endpoint               = "enabled"
    }
  }
}
```

IaC: The eks-cluster module now supports a new default_bdm_iops input variable, which allows specifying an explicit IOPS value for the default block device mapping without needing to specify an entirely custom block device mapping.
