Configure Vault for ActiveMQ

This deployment requires redeployment of ActiveMQ

1. Vault Setup

CODE

cd CX-4.10.5/kubernetes

CODE

helm repo add secrets-store-csi-driver https://kubernetes-sigs.github.io/secrets-store-csi-driver/charts
helm install csi-secrets-store secrets-store-csi-driver/secrets-store-csi-driver --namespace vault

CODE

kubectl -n vault exec -it vault-0 -- sh

Create a KV-v2 secret in Vault:

CODE

vault secrets enable -path=kv kv-v2

CODE

vault kv put kv/activemq/broker \
    activemq.username=admin \
    activemq.password=Expertflow123

Verify:

CODE

vault kv get kv/activemq/broker

Write policy for the role

CODE

vault policy write ef-policy - <<EOF
path "/transit/export/*" {
  capabilities = ["read"]
}
path "database/creds/*" {
 capabilities = ["read"]
}
path "kv/data/activemq/broker" {
  capabilities = ["read"]
}
EOF

Attach policy to the role

CODE

vault write auth/approle/role/expertflow policies="ef-policy"

2. Vault Role for Kubernetes Authentication

Create a policy for Kubernetes role in Vault:

CODE

vault policy write activemq-kv - <<EOF
path "kv/data/activemq/broker" {
  capabilities = ["read"]
}
EOF

Create a Kubernetes role in Vault:

CODE

vault auth enable kubernetes

CODE

vault write auth/kubernetes/config \
    token_reviewer_jwt="$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)" \
    kubernetes_host="https://kubernetes.default.svc:443" \
    kubernetes_ca_cert=@/var/run/secrets/kubernetes.io/serviceaccount/ca.crt

CODE

vault write auth/kubernetes/role/expertflow \
    bound_service_account_names=default \
    bound_service_account_namespaces=ef-external \
    policies=activemq-kv \
    ttl=87600h

CODE

exit

3. Apply SecretProviderClass, ClusterRole and ClusterRoleBinding

CODE

kubectl apply -f pre-deployment/activemq-vault

4. Deploy / Restart Pods

CODE

kubectl delete pod -n vault <vault-csi-provider-pod>

CODE

# Restart ActiveMQ pod 
kubectl delete pod -n ef-external <activemq-pod>
