Closed Abuelodelanada closed 3 years ago

Abuelodelanada commented 3 years ago

In config.yaml we have:

  admin-password:
    type: string
    default: ''
    descriptions: Password used by root user to setup cluster

And wen trying to deploy, the following happens

juju status:

But if in config.yaml we set up the following:

  admin-password:
    type: string
    default: 'Password'
    descriptions: Password used by root user to setup cluster

MySQL units are deployed

This issue can be avoided running:

$ juju deploy ./mysql.charm --config admin-password=Password
