Default developer configuration

If you build this image with MQ Advanced for Developers, then an optional set of configuration can be applied automatically. This configures your Queue Manager with a set of default objects that you can use to quickly get started developing with IBM MQ. If you do not want the default objects to be created you can set the MQ_DEV environment variable to false.

Environment variables

The MQ Developer Defaults supports some customization options, these are all controlled using environment variables:

  • MQ_DEV - Set this to false to stop the default objects being created.
  • MQ_ADMIN_PASSWORD - Changes the password of the admin user. Must be at least 8 characters long.
  • MQ_APP_PASSWORD - Changes the password of the app user. If set, this will cause the DEV.APP.SVRCONN channel to become secured and only allow connections that supply a valid userid and password. Must be at least 8 characters long.
  • MQ_TLS_KEYSTORE - DEPRECATED. See section Supplying TLS certificates in usage document. Allows you to supply the location of a PKCS#12 keystore containing a single certificate which you want to use in both the web console and the queue manager. Requires MQ_TLS_PASSPHRASE. When enabled the channels created will be secured using the TLS_RSA_WITH_AES_128_CBC_SHA256 CipherSpec. Note: you will need to make the keystore available inside your container, this can be done by mounting a volume to your container.
  • MQ_TLS_PASSPHRASE - DEPRECATED. See section Supplying TLS certificates in usage document. Passphrase for the keystore referenced in MQ_TLS_KEYSTORE.

Details of the default configuration

The following users are created:

  • User admin for administration (in the mqm group). Default password is passw0rd.
  • User app for messaging (in a group called mqclient). No password by default.

Users in mqclient group have been given access connect to all queues and topics starting with DEV.** and have put, get, pub, sub, browse and inq permissions.

The following queues and topics are created:

  • DEV.QUEUE.1
  • DEV.QUEUE.2
  • DEV.QUEUE.3
  • DEV.DEAD.LETTER.QUEUE - configured as the Queue Manager's Dead Letter Queue.
  • DEV.BASE.TOPIC - uses a topic string of dev/.

Two channels are created, one for administration, the other for normal messaging:

  • DEV.ADMIN.SVRCONN - configured to only allow the admin user to connect into it. A user and password must be supplied.
  • DEV.APP.SVRCONN - does not allow administrative users to connect. Password is optional unless you choose a password for app users.

A new listener is created (the SYSTEM listener is fine, but system objects are not shown by default in the web console):

  • DEV.LISTENER.TCP - listens on port 1414.

Web Console

By default the MQ Advanced for Developers image will start the IBM MQ Web Console that allows you to administer your Queue Manager running on your container. When the web console has been started, you can access it by opening a web browser and navigating to https://:9443/ibmmq/console. Where is replaced by the IP address of your running container.

When you navigate to this page you may be presented with a security exception warning. This happens because, by default, the web console creates a self-signed certificate to use for the HTTPS operations. This certificate is not trusted by your browser and has an incorrect distinguished name.

If you choose to accept the security warning, you will be presented with the login menu for the IBM MQ Web Console. The default login for the console is:

  • User: admin
  • Password: passw0rd

If you wish to change the password for the admin user, this can be done using the MQ_ADMIN_PASSWORD environment variable. If you supply a PKCS#12 keystore using the MQ_TLS_KEYSTORE environment variable, then the web console will be configured to use the certificate inside the keystore for HTTPS operations.

If you do not wish the web console to run, you can disable it by setting the environment variable MQ_ENABLE_EMBEDDED_WEB_SERVER to false.
