Fix Submariner deployment

Prerequisites

• Submariner deployments can occasionally become tangled with dangling clusters or with connection issues.
• One way to resolve these is by deleting all of the pods in the submariner-operator namespace.
• For Submariner on Azure, occasionally submariner may fall into a degraded state due to NAT being turned off. The fix for this is to patch the azure clusters to enable NAT.
• This can be done using the fix_submariner_deployment.sh script.

Running the script

• define the clusters you wish to apply the fix to in the list
• The fix submariner deployment can perform a hard reset of all of the clusters provided.
• Replace the blank oc login command with either a token login, or kubeadmin credentials
• Uncomment the # oc delete pods --all -n submariner-operator line if you wish to refresh the pods.
• Uncomment the # oc -n submariner-operator scale deploy submariner-addon --replicas=0 # oc patch Submariner submariner --type=merge -p '{"spec":{"natEnabled": true}}' -n submariner-operator # oc -n submariner-operator scale deploy submariner-addon --replicas=1 lines should you wish to apply patches to azure clusters

Get ManagedCluster credentials

Prerequisites

• If a hub cluster fails and you need to gather credentials, or you wish to gather the kubeadmin credentials for all managed clusters you can use the get_managedcluster_credentials.sh script.

Running the script

• To run the script simply define the credentials for the RHACM hub cluster you wish to gather credentials for.
• Run get_managedcluster_credentials.sh
