Uninstalling IBM Fusion

Steps to uninstall IBM Fusion from Red Hat® OpenShift® web console.

1. Export IBM Fusion namespace as an environment variable.
   Note: If the IBM Fusion is installed in a different namespace, replace the existing namespace:

   export FUSION_NS="ibm-spectrum-fusion-ns"

2. Run the following script:

   oc project "$FUSION_NS"
   echo "Fusion namespace: $FUSION_NS"
   echo "Labeling namespace $FUSION_NS with uninstalling=true"
   oc label namespace "$FUSION_NS" uninstalling=true --overwrite

   ISF_CRDS=$(oc get crd -o json | jq -r '.items[] | select(.spec.group | endswith("isf.ibm.com")) | .metadata.name')
   
   for CRD in $ISF_CRDS
   do
       oc delete crd $CRD --wait=false
       RES_LIST=$( oc get $CRD --all-namespaces -o=jsonpath='{range .items[]}{.metadata.namespace}:{.metadata.name}{"\n"}{end}')
       sleep 1
       if [ -n "$RES_LIST" ]
       then    
           while IFS= read -r res; do
               namespace=$(echo "$res" | cut -d ':' -f 1)
               res_name=$(echo "$res" | cut -d ':' -f 2)
               echo "patching resource $res_name in namespace $namespace"
               oc patch $CRD $res_name -n $namespace --type merge -p '{"metadata":{"finalizers": []}}'
           done <<< "$RES_LIST"
