For more information, see Updating the CLI and the CLI change log.

April 2024

24 April 2024

Red Hat OpenShift on IBM Cloud 4.15 is available.
You can create or update clusters to version 4.15. With Red Hat OpenShift on IBM Cloud version 4.15, you get the latest features, as well as component updates on Red Hat OpenShift on IBM Cloud. For more information, see the 4.15 change log.
Important networking changes for Red Hat OpenShift on IBM Cloud VPC clusters created with version 4.15.
For more information, see the 4.15 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 4.15.
Beginning with version 4.15, 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 4.15 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 4.15 version information, Understanding Secure by Default Cluster VPC Networking, and Managing outbound traffic protection in VPC clusters.
Managing outbound traffic protection in new version 4.15 VPC clusters.
With the introduction of Secure by Default Cluster VPC networking in version 4.15 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.
Red Hat CoreOS worker nodes are available for new VPC clusters beginning with version 4.15.
You can now specify the Red Hat Enterprise Linux CoreOS (RHCOS) operating system when you provision a new VPC cluster. Note that the OpenShift Data Foundation and cluster autoscaler add-ons do not yet support RHCOS worker nodes. If you need to install these add-ons in your cluster, use RHEL worker nodes instead. For more information, see the Red Hat Enterprise Linux CoreOS (RHCOS) documentation.

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 Red Hat OpenShift on IBM Cloud. 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 oc nlb-dns monitor disable command to disable the Akamai health check that the migration automatically configured for your subdomain.
