How to check if a namespace is active-CodePudding

I'm using the following command to check if the namespace is active

kubectl wait --for=condition=items.status.phase=Active namespace/mynamespace --timeout=2s

This always returns "error: timed out waiting for the condition on namespaces/mynamespace" although the namespace is active. Is there a correct way to wait for the namespace to be active? This script is part of a job to check the namespace is active after a AKS cluster restart.

CodePudding user response：

To date status is not a recognized condition. Try:

while ! [ "$(kubectl get ns <change to your namespace> -o jsonpath='{.status.phase}')" == "Active" ]; do echo 'Waiting for namespace to come online. CTRL-C to exit.'; sleep 1; done

CodePudding user response：

timeout_value=3
starttime=$(date  %s)
while [ $(( $(date  %s) - $timeout_value )) -lt $starttime ]; do
     status=$(kubectl get ns mynamespace -o jsonpath='{.status.phase}')
     status=${status:-"X"}
     echo $status
     if [ "$status" == "Active" ];then
        echo " test"
        break
     fi
done

Modified @gohm'c answer to include a timeout value of 3 seconds.
