1. Create a Namespace for the HiveMQ/Postgres deployment.
   You can skip this step you want to run everything in “default” namespace.

   Execute the following command to create a namespace:

   Code Block
   language bash
   kubectl create namespace <namespace name>

   Switch to the newly created namespace:

   Code Block
   language bash
   kubectl config set-context --current --namespace=<namespace name>

2. Deploy Postgres

   Add the Bitnami Helm repository:

   Code Block
   language bash
   helm repo add bitnami https://charts.bitnami.com/bitnami

   Create a postgres_values.yaml file to configure Postgres deployment:

   Code Block
   language yaml
   global: storageClass#storageClass: "rook-ceph-block" postgresql: auth: password: password postgresPassword: password username: admin primary: initdb: scriptsConfigMap: ese-db-init

   Create a ConfigMap called ese-db-init containing the ese-db-init.sql script, which creates tables and inserts data for testing purposes:
   

   View file
   name 1_permissions.sql

   View file
   name 0_ese-db-init.sql

   Code Block
   language bash
   kubectl create configmap ese-db-init --from-file 0_ese-db-init.sql --from-file 1_permissions.sql

   Deploy Postgres using Helm:

   Code Block
   language bash
   helm upgrade postgres --install bitnami/postgresql --values postgres_values.yaml

   Verify the status of the pod:

   Code Block
   language bash
   kubectl get pods

   If an error occurs, check the pod logs:

   Code Block
   language bash
   kubectl logs <pod name>

   Connect to the Postgres pod to verify the connection:

   Code Block
   language bash
   psql --host 127.0.0.1 -U postgres -d postgres -p 5432

   Use the following commands in the Postgres shell to interact with the database:

   • \l: List the databases.

   • \c <db name>: Connect to a specific database.

   • \dt: List the tables from the connected database.

   • select * from users;
     

3. Deploy HiveMQ with Enterprise Security Extension (ESE)
