New! IBM Cloud Kubernetes Service version 1.30.
You can now create or update clusters to Kubernetes version 1.30. With Kubernetes 1.30, you get the latest stable enhancements from the Kubernetes community as well as enhancements to the IBM Cloud product.
IBM Cloud Kubernetes Service version 1.30 Kubernetes certification
IBM Cloud Kubernetes Service version 1.30 is now Kubernetes certified.
Important networking changes for IBM Cloud Kubernetes Service VPC clusters created at version 1.30.
For more information, see the 130 version information and Understanding Secure by Default Cluster VPC Networking.
Important changes to the default cluster provisioning behavior for new VPC clusters beginning with version 1.30.
Beginning with version 1.30, there is a new option available at cluster creation time via the UI, CLI, API, and Terraform. This new option manages outbound traffic protection for the cluster. The default behavior is to have outbound traffic protection enabled, which means new version 1.30 VPC clusters won't have access the public internet by default. If your cluster needs access to the public internet, you must specifically include the option (from the UI, CLI, API, and Terraform) to disable outbound traffic protection. Note that you can also disable outbound traffic protection after your cluster is created. You can also selectively allow outbound traffic as needed after your cluster is created. If you provision clusters via automation, make sure to adjust your automation accordingly.
For more information, see the 1.30 version information, Understanding Secure by Default Cluster VPC Networking, and Managing outbound traffic protection in VPC clusters.
Managing outbound traffic protection in new version 1.30 VPC clusters.
With the introduction of Secure by Default Cluster VPC networking in version 1.30 and later clusters, there are several scenarios where you might need to adjust the security group settings for your clusters to allow outbound traffic to certain resources. For more information, see Managing outbound traffic protection in VPC clusters.

Networking changes for VPC clusters 1.28 and later
In version 1.27 and earlier, VPC clusters pull container images from the IBM Cloud Container Registry through a private cloud service endpoint for the Container Registry.

Trusted profile updates for Kubernetes clusters version 1.28 and later.
You can now give trusted profiles service level access to your clusters, then use a federated ID, like App ID, to access the cluster at the level assigned in the trusted profile since trusted profile identities are now synced into the cluster RBAC. For more information, see Creating trusted profiles and Logging in with a federated ID.
New! Updated GPU drivers with version 1.28 clusters.
With the release of IBM Cloud Kubernetes Version 1.28, GPU drivers moved to the 500 series version for all GPU worker node flavors.

Unsupported Kubernetes version 1.17
To continue receiving important security updates and support, you must update the cluster to a supported version immediately.

June 2021

From 07 to 31 July 2021, the DNS provider is changed from Cloudflare to Akamai for all containers.appdomain.cloud, containers.mybluemix.net, and containers.cloud.ibm.com domains for all clusters in IBM Cloud Kubernetes Service. Review the following actions that you must make to your Ingress setup.

  • If you currently allow inbound traffic to your classic cluster from the Cloudflare source IP addresses, you must also allow inbound traffic from the Akamai source IP addresses before 07 July. After the migration completes on 31 July, you can remove the Cloudflare IP address rules.

  • The Akamai health check does not support verification of the body of the health check response. Update any custom health check rules that you configured for Cloudflare that use verification of the body of the health check responses.

  • Cluster subdomains that were health checked in Cloudflare are now registered in the Akamai DNS as CNAME records. These CNAME records point to an Akamai Global Traffic Management domain that health checks the subdomains. When a client runs a DNS query for a health checked subdomain, a CNAME record is returned to the client, as opposed to Cloudflare, in which an A record was returned. If your client expects an A record for a subdomain that was health checked in Cloudflare, update your logic to accept a CNAME record.

  • During the migration, an Akamai Global Traffic Management (GTM) health check was automatically created for any subdomains that had a Cloudflare health check. If you previously created a Cloudflare health check for a subdomain, and you create an Akamai health check for the subdomain after the migration, the two Akamai health checks might conflict. Note that Akamai GTM configurations don't support nested subdomains. In these cases, you can use the ibmcloud ks nlb-dns monitor disable command to disable the Akamai health check that the migration automatically configured for your subdomain.
