The purpose of this document is to provide a detailed description of the procedure for performing a rolling upgrade of a node pool.
Note: Running maxSurge will require extra resources within the infrastructure.
Environment
2.3
Resolution
Pre-requisites
Ensure the workload cluster is in a healthy state by running cluster diagnostics to confirm its overall health.
Verify that the network function is up and running by conducting pre-checks to ensure the application is healthy.
Before beginning the node pool upgrade, schedule a maintenance window or implement traffic isolation.
Procedure
Upgrade the control plane for the workload cluster to the tbr-bom-2.3.0-v1.24.10 BOM version.
Upgrade the node pool to the tbr-bom-2.3.0-v1.24.10 BOM version.
Under the Edit node pool panel, select the tbr-bom-2.3.0-v1.24.10 BOM version and update the VM template.
Manually modify the TCAnodepool CR to update the TKG upgrade strategy as illustrated below: In this example the workload cluster is wc04 and the node pool is np1:
