- username - password
This charm configures the wildfly domain controller node to listen on the public IP assigned.
Accessing the web console
The management console will be available at http://server-ip:9990
For the first time when you try to access the management web console it will take you to a page which says wildfly server is running but you need to create a user to access the console.
The default username is "admin" (however you can change it any time using the command given below). There is no default password set so you need to set the password explicitly in order to log into the management console.
To set a custom username (optional step if you are fine using admin as username)
- juju set wildfly-ha-master username=desired_name
To set a desired password (a must-do step, in order to be able to access the management web console)
- juju set wildfly-ha-master password=desired_password
