Allow Cloud Armor

Duration: 2 min | Persona: Org Admin

In this section, you will grant the appropriate IAM role for the Tenant project’s service account. This will allow later this service account to provision Cloud Armor.

Initialize variables:

WORK_DIR=~/
source ${WORK_DIR}acm-workshop-variables.sh

Define role

Define the compute.securityAdmin role with an IAMPolicyMember for the Tenant project’s service account:

cat <<EOF > ${WORK_DIR}$HOST_PROJECT_DIR_NAME/projects/$TENANT_PROJECT_ID/security-admin.yaml
apiVersion: iam.cnrm.cloud.google.com/v1beta1
kind: IAMPolicyMember
metadata:
  name: security-admin-${TENANT_PROJECT_ID}
  namespace: config-control
  annotations:
    config.kubernetes.io/depends-on: iam.cnrm.cloud.google.com/namespaces/config-control/IAMServiceAccount/${TENANT_PROJECT_ID},resourcemanager.cnrm.cloud.google.com/namespaces/config-control/Project/${TENANT_PROJECT_ID}
spec:
  memberFrom:
    serviceAccountRef:
      name: ${TENANT_PROJECT_ID}
  role: roles/compute.securityAdmin
  resourceRef:
    kind: Project
    external: projects/${TENANT_PROJECT_ID}
EOF

Wait until you see the Sync status column as Synced and the Reconcile status column as Current.

Run this command:

gcloud alpha anthos config sync repo describe \
    --project $HOST_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". All the managed_resources listed should have STATUS: Current too.
