OCP k8s CRC local monitoring

 HOWTO



Add memory 


$ crc stop
INFO Stopping kubelet and all containers...       
INFO Stopping the instance, this may take a few minutes... 
Stopped the instance
dave@fedora:~/Downloads$ crc config set memory 14336
Changes to configuration property 'memory' are only applied when the CRC instance is started.
If you already have a running CRC instance, then for this configuration change to take effect, stop the CRC instance with 'crc stop' and restart it with 'crc start'.
dave@fedora:~/Downloads$  crc config set enable-cluster-monitoring true
Successfully configured enable-cluster-monitoring to true
dave@fedora:~/Downloads$ crc start

To confirm your system is ready, and you have the needed system bundle, please run 'crc setup' before 'crc start'.
dave@fedora:~/Downloads$ crc setup 
CRC is constantly improving and we would like to know more about usage (more details at https://developers.redhat.com/article/tool-data-collection)
Your preference can be changed manually if desired using 'crc config set consent-telemetry <yes/no>'
Would you like to contribute anonymous usage statistics? [y/N]: y
Thanks for helping us! You can disable telemetry with the command 'crc config set consent-telemetry no'.

Now using project "demo" on server "https://api.crc.testing:6443".

You can add applications to this project with the 'new-app' command. For example, try:

    oc new-app rails-postgresql-example

to build a new example application in Ruby. Or use kubectl to deploy a simple Kubernetes application:

    kubectl create deployment hello-node --image=registry.k8s.io/e2e-test-images/agnhost:2.43 -- /agnhost serve-hostname
