How to append new ip in existing authorized network list on google cloud kubernetes cluster-CodePudding

Right now, I can add my ip using

gcloud container clusters update core-cluster --zone=asia-southeast1-a --enable-master-authorized-networks --master-authorized-networks w.x.y.z/32

but it overrides all the existing authorized networks that was already there.

Is there any way to append the new ip to the existing list of authorized networks?

CodePudding user response：

No. You'll need to first get the current value, append that to the additional value and then update with the new aggregate list.

You could automate what @Gari Singh said using gcloud, jq and tr. See below for doing it with CLI:

NEW_CIDR=8.8.4.4/32
export CLUSTER=test-psp
OLD_CIDR=$(gcloud container clusters describe $CLUSTER --format json | jq -r '.masterAuthorizedNetworksConfig.cidrBlocks[] | .cidrBlock' | tr '\n' ',')
echo "The existing master authorized networks were $OLD_CIDR"
gcloud container clusters update $CLUSTER --master-authorized-networks "$OLD_CIDR$NEW_CIDR" --enable-master-authorized-networks
