Preparing to install IBM Master Data Management

Plan and prepare to install IBM Master Data Management.

Optional tasks

The following tasks are optional before installing IBM Master Data Management:
Provide self-defined credentials to use instead of generated credentials

By default, the IBM Master Data Management installation generates credentials that are used for authenticating the service to IBM® WebSphere® Liberty Profile, RabbitMQ, Elasticsearch, and Redis. If you choose, you can define your own credentials to use in place of the generated ones.

Note: Credentials must be at least 8 characters in length and contain at least one lowercase letter, one uppercase letter, and one number. If invalid credentials are provided, the operator logs an error and uses generated credentials instead.

Required role: To complete this task, you must be a cluster administrator.

To define and provide your own credentials before installing IBM Master Data Management, create a secret containing your chosen credentials named mdm-user-defined-auth. Use the following format:
secrets:
  user_defined_auth:
    name: mdm-user-defined-auth
    elasticsearch:
      password: elasticsearch.password
    rabbitmq:
      erlang_cookie: rabbitmq.erlang-cookie
      management_password: rabbitmq.management-password
      password: rabbitmq.password
    redis:
      compose_password: redis.compose_password
    wlp:
      keystore_pass: wlp.key.store.password
Sample secret template:
apiVersion: v1
data:
  elasticsearch.password: [ENCODED_CRED]
  rabbitmq.management-password: [ENCODED_CRED]
  rabbitmq.password: [ENCODED_CRED]
  rabbitmq.erlang-cookie: [ENCODED_CRED]
  redis.compose_password: [ENCODED_CRED]
  wlp.key.store.password: [ENCODED_CRED]
kind: Secret
metadata:
  name: mdm-user-defined-auth
  namespace: $MDM_OPERAND_NAMESPACE
type: Opaque
Note: If you prefer to set your self-defined credentials after completing the installation, see Post-installation setup for IBM Master Data Management.
