Issue

  • The length APPLICATION_NAME is not validated in the UI. The creation produces some garbage, e.g image streams & deployment configurations.

  • Service name limit is at most 24 chars so we shall check the service name in the template
    Eg-https://github.com/openshift/training/blob/master/beta4/eap6-basic-sti.json#L117
    "name": "${APPLICATION_NAME}-https-service",

  • Here we shall allow ${APPLICATION_NAME} to be of 10 chars only as already https-service is of 14 chars.

  • From the command line you will get an error.
