Set up NetworkPolicies logging

Platform Admin Duration: 5 min | Persona: Platform Admin

In this section, you will set up the NetworkPolicies logging in order to get more insights about the logs generated by the denied or allowed requests controlled by NetworkPolicies thanks to the GKE Dataplane V2 feature.

Define variables:

source ${WORK_DIR}

Define Network Policy logging

cat <<EOF > ${WORK_DIR}$GKE_CONFIGS_DIR_NAME/networkpolicies-logging.yaml
kind: NetworkLogging
  name: default
      log: false
      delegate: false
      log: true
      delegate: false

Deploy Kubernetes manifests

git add . && git commit -m "NetworkPolicies logging" && git push origin main

Check deployments

List the Kubernetes resources managed by Config Sync in GKE cluster for the GKE cluster configs repository:

gcloud alpha anthos config sync repo describe \
    --project $TENANT_PROJECT_ID \
    --managed-resources all \
    --sync-name root-sync \
    --sync-namespace config-management-system

Wait and re-run this command above until you see "status": "SYNCED".

Alternatively, you could also see this from within the Cloud Console, by clicking on this link:

echo -e "${GKE_NAME}&id=${GKE_NAME}&project=${TENANT_PROJECT_ID}"

Wait until you see the Sync status column as SYNCED. And then you can also click on View resources to see the details.

List the GitHub runs for the GKE cluster configs repository:

cd ${WORK_DIR}$GKE_CONFIGS_DIR_NAME && gh run list
