Migrating Project Specific Resource Quotas

ResourceQuotas are kubernetes resources that can be applied from the source cluster to the target cluster. No changes are necessary.

Checking values of individual ResourceQuotas

You can use this section if you are handling one resourcequota at a time.

To list ResourceQuotas in a project, run

PROJECT_NAME=<<projectname>>
oc get resourcequota -n $PROJECT_NAME

To get a specific ResourceQuota within an OpenShift project

PROJECT_NAME=<<projectname>>
RQ_NAME=<<resourcequotaname>>
oc get resourcequota $RQ_NAME -n $PROJECT_NAME -o yaml \
    | yq e 'del(.metadata.creationTimestamp)' - \
    | yq e 'del(.metadata.resourceVersion)' - \
    | yq e 'del(.metadata.selfLink)' - \
    | yq e 'del(.metadata.uid)' - \
    | yq e 'del(.status)' -  \
    | yq e 'del(.metadata.managedFields)' - \
    | yq e 'del(.metadata.annotations)' - \
    | yq e 'del(.metadata.manager)' - \
    | yq e 'del(.metadata.operation)' - \
    | yq e 'del(.metadata.time)' - 

Export all project level ResourceQuotas

To export ResourceQuotas across all the selected set of namespaces in the clusterconfigs/namespaces folder , run the following script. This will save the ResourceQuotas in clusterconfigs/namespaces/NAMESPACE folder, each with a unique name.

for ns in $(ls clusterconfigs/namespaces); do 
    for i in $(oc get resourcequotas -n $ns -o jsonpath='{.items[*].metadata.name}'); do
     echo "Exporting resource quotas" $i "for namespace" $ns; \
     mkdir -p clusterconfigs/namespaces/$ns
     oc get resourcequota $i -n $ns -o yaml \
        | yq e 'del(.metadata.creationTimestamp)' - \
        | yq e 'del(.metadata.resourceVersion)' - \
        | yq e 'del(.metadata.selfLink)' - \
        | yq e 'del(.metadata.uid)' - \
        | yq e 'del(.status)' -  \
        | yq e 'del(.metadata.managedFields)' - \
        | yq e 'del(.metadata.annotations)' - \
        | yq e 'del(.metadata.manager)' - \
        | yq e 'del(.metadata.operation)' - \
        | yq e 'del(.metadata.time)' -  > clusterconfigs/namespaces/$ns/$i-quota.yaml      
    done; 
done
