Apply the required Container Runtime Interface (CRI-O) settings to your cluster nodes.
Extended description
Restriction: The
apply-crio command is
applicable only if you are installing one or more of the following services:
- Cognos® Analytics
- Data Virtualization
- Db2®
- Db2 Big SQL
- Db2
Warehouse
- Watson™ Discovery
- Watson Knowledge
Catalog
- Watson Studio
- Watson Machine Learning
Accelerator
These settings are required on all deployment environments except IBM® Cloud.
To ensure that the preceding services can run correctly, you must adjust the CRI-O container settings to specify the maximum number
of processes.
These settings are required for the CRI-O
container runtime on the OpenShift® Container Platform
cluster.
Run this command to apply the required CRI-O
settings to your cluster nodes.
Important: This command performs a rolling restart of the worker nodes on the
cluster.
