Confirm the Terraform plan doesn't destroy any of these resources before running terraform apply. Some of the following commands will need to be run depending on the particular cluster configuration. Terraform users of clusters with names beginning with digits will need to move resources prior to upgrading to kOps 1.22.If you applied the plan without first orphaning all of these objects, fix the cluster by re-running Then re-run terraform plan until there are no such objects in the plan. Prior to applying the plan, you will need to orphan all theĪws_s3_bucket_object objects the plan wants to destroy. You subsequently downgrade to an earlier version of kOps, the generated plan will delete theseįiles, breaking the cluster. If, after upgrading kOps and applying a new Terraform plan, Users on older versions must follow Terraform's recommended upgrade path of applying one minor version at a time prior to running kops update cluster -target terraform. Terraform support now requires Terraform >=0.15.0. See the documentation for more information. Cilium users will need to migrate to a distribution with a newer Linux kernel.Īmazon Linux 2 users are encouraged to use the AMIs based on the 5.10 Linux kernel. Support for Cilium and RHEL 8 has been removed. Support for importing and converting kubeup clusters has been removed. It is replaced by the new kops get assets -copy command. The assets phase of kops update cluster has been removed. The legacy location for downloads s3:// has been deprecated and will not be used for new releases. The legacy addons from have been deprecated and will not be available in Kubernetes 1.23+. Support for Kubernetes versions 1.15 and 1.16 has been removed. If you have file assets or other files needed by kube-apiserver, you must put these into /srv/kubernetes/kube-apiserver/ or /srv/kubernetes/kube-controller-manager, respectively.įor file assets, it means adding an explicit path as shown below:įileAssets : - name : audit-policy-config path : /srv/kubernetes/kube-apiserver/audit-policy-config.yaml # make sure you add the path roles : - Master content : | apiVersion: /v1 kind: Policy rules: - level: Metadata Other breaking changes ¶ This also means the files in the default file assets path will be unavailable. KOps can now use external-dns as a drop-in replacement for dns-controller.īreaking changes ¶ Control plane pods no longer mount /srv/kubernetes ¶įor security reasons, /srv/kubernetes is no longer mounted in the kube-apiserver and kube-controller-manager Pods. New clusters running Kubernetes 1.22 will have AWS EBS CSI driver enabled by default. See the documentation on How to rotate all secrets / credentials KOps now implements graceful rotation of its Certificate Authorities and the serviceĪccount signing key. Using export KOPS_FEATURE_FLAGS="-TerraformManagedFiles". This feature may be temporarily disabled by turning off the TerraformManagedFiles feature flag This defers changes to these files until the time of terraform apply. The kOps Terraform support now renders managed files through the Terraform configuration instead To provisionĪn SSH public key on a new cluster, use the -ssh-public-key flag to kops create cluster. New clusters on AWS will no longer provision an SSH public key by default. Since 1.22.0 Cluster default behaviour changes from true to false. See GPU support Breacking change in NodeLocalDNS ¶ KOps can now provision instances with nvidia GPUs and configure it for container workloads without the need of hooks and operators. UseServiceAccountExternalPermissions: trueĬurrently this is only available using the AWS cloud provider. Moving from a Single Master to Multiple HA MastersĬontrol plane pods no longer mount /srv/kubernetes
