The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
Chapter 2 Updating to an Errata Release
This section describes how to update Oracle Cloud Native Environment to an errata release. You can use this procedure to update Kubernetes to the latest errata release. This updates the environment within the same major.minor release. For example, Release 1.1 is updated to the latest available software, or Release 1.2 is updated to the latest software.
Perform each step in this chapter in order to update your environment to an errata release.
Do not change the ULN channel or Oracle Linux yum server repository. They should remain as you set them during the installation.
2.1 Updating the Operator Node
Update the operator node with the new Oracle Cloud Native Environment software packages.
-
On the operator node, stop the
olcne-api-server
service:sudo systemctl stop olcne-api-server.service
-
Update the Platform CLI, Platform API Server, and utilities packages.
On Oracle Linux 7 enter:
sudo yum update olcnectl olcne-api-server olcne-utils
On Oracle Linux 8 enter:
sudo dnf upgrade olcnectl olcne-api-server olcne-utils
-
Start the
olcne-api-server
service:sudo systemctl start olcne-api-server.service
2.2 Updating the Kubernetes Nodes
Update the Kubernetes nodes with the new Oracle Cloud Native Environment packages.
-
On the node to update, stop the
olcne-agent
service:sudo systemctl stop olcne-agent.service
-
Update the Platform Agent and utilities packages.
On Oracle Linux 7 enter:
sudo yum update olcne-agent olcne-utils
On Oracle Linux 8 enter:
sudo dnf upgrade olcne-agent olcne-utils
-
Start the
olcne-agent
service:sudo systemctl start olcne-agent.service
2.3 Updating the Kubernetes Cluster
Update the cluster to the latest Kubernetes errata release.
On the operator node, use the olcnectl module
update command to update to the latest Kubernetes errata
release. This example updates a Kubernetes module
named mycluster
in the
myenvironment
environment to the latest Kubernetes
errata release.
olcnectl module update \ --environment-name myenvironment \ --name mycluster
If you are using the NGINX load balancer deployed by the
Platform CLI, you should also update NGINX on the control
plane nodes. You specify the location from which to pull the NGINX
container image used to update NGINX using the
--nginx-image
option. For example, include this
additional line in the olcnectl module update
command to update NGINX from the Oracle Container Registry:
--nginx-image container-registry.oracle.com/olcne/nginx:1.17.7
Make sure you update to the latest NGINX release for your Oracle Cloud Native Environment release. To get the version number of the latest NGINX container image, see Release Notes.
The nodes in the cluster are updated to the latest errata release and the cluster's health is validated.
If you are updating from Release 1.2.0 to 1.2.2, or from Release
1.1.x to 1.1.10, you must also update your
cluster to configure access to externalIPs
.
For information on the steps required, see
Chapter 5, Updating to Release 1.2.2 and 1.1.10.
