Installation of PostgreSQL server

...

1. Add the PostgreSQL repo to your Helm:

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

2. Update the repo to the latest version:

   Code Block
   language bash
   helm repo update bitnami

3. Create a new namespace to place the PostgreSql in:

   Code Block
   kubectl create namespace db

4. Switch the KubeCtl context to the new namespace:

   Code Block
   kubectl config set-context --current --namespace=db

5. Install PostgreSQL to the new namespace:

   Code Block
   language bash
   helm upgrade postgres --install bitnami/postgresql --namespace db

6. If everything is correct, then PostgreSQL in installed to namespace “db”. The default name for the admin user is “postgres”. To get the password for "postgres" user run the following command and note the password:

   Code Block
   language bash
   export PGPASSWORD=$(kubectl get secret --namespace db postgres-postgresql -o jsonpath="{.data.postgres-password}" | base64 -d) && echo $PGPASSWORD

...

1. Download a simple configuration file for Enterprise Security Extensions in the example below.
   Replace the “password” in <db-password>password</db-password> with the value of PGPASSWORD variable.

   View file
   name config.xml

2. In the hivemq namespace create a configMap ese-config from the file config.xml

   Code Block
   language bash
   kubectl create configmap ese-config --from-file config.xml --namespace hivemq

3. Edit values.yaml file of hivemq-operator and update section hivemq.extensions, having name: hivemq-enterprise-security-extension
   Update the old hivemq-enterprise-security-extension block from this:

   Code Block
   language yaml
   - name: hivemq-enterprise-security-extension extensionUri: preinstalled enabled: false # Note that this is just an example initialization routine. Make sure this points to the current JDBC version you require for your configuration. initialization: | # Download JDBC driver for PostgreSQL [[ ! -f drivers/postgres-jdbc.jar ]] && curl -L https://jdbc.postgresql.org/download/postgresql-42.2.14.jar --output drivers/jdbc/postgres.jar

   To this:

   Code Block
   language yaml
   - name: hivemq-enterprise-security-extension extensionUri: preinstalled enabled: true configMap: ese-config initialization: | [[ ! -f conf/config.xml ]] && [[ -f /conf-override/extensions/hivemq-enterprise-security-extension/config.xml ]] && ln -s /conf-override/extensions/hivemq-enterprise-security-extension/config.xml conf/config.xml && [[ ! -f drivers/postgres-jdbc.jar ]] && curl -L https://jdbc.postgresql.org/download/postgresql-42.7.1.jar --output drivers/jdbc/postgres.jar

4. Re-deploy hivemq-operator with updated values.yaml

   Code Block
   helm upgrade hivemq --install hivemq/hivemq-operator --values values.yaml --namespace hivemq

   – for ease of use we switch the namespace back to hivemq kubectl config set-context --current --namespace=hivemq

5. If everything is correct, The HiveMQ log contains info about using the correct license:
