Description of problem: When running the installer wizard, the host configuration section is confusing as it does not explain what kind of input is expected. There are seemingly unconnected paragraphs of text about what Masters and Nodes do. It is not described however what kind of hostname/IP is expected as input: master, node, or both, or something else. Version-Release number of selected component (if applicable): 3.1.0 How reproducible: always Steps to Reproduce: 1. atomic-openshift-installer install 2. press Y 3. press Enter Actual results: following text is displayed: ***Host Configuration*** The OpenShift Master serves the API and web console. It also coordinates the jobs that have to run across the environment. It can even run the datastore. For wizard based installations the database will be embedded. It's possible to change this later using etcd from Red Hat Enterprise Linux 7. Any Masters configured as part of this installation process will also be configured as Nodes. This is so that the Master will be able to proxy to Pods from the API. By default this Node will be unscheduleable but this can be changed after installation with 'oadm manage-node'. The OpenShift Node provides the runtime environments for containers. It will host the required services to be managed by the Master. http://docs.openshift.com/enterprise/latest/architecture/infrastructure_components/kubernetes_infrastructure.html#master http://docs.openshift.com/enterprise/latest/architecture/infrastructure_components/kubernetes_infrastructure.html#node Enter hostname or IP address: []: Expected results: Instead of unconnected paragraphs of text - show a description of what this step is actually about: user needs to provide hostnames of all masters/nodes that will take part in the environment that is going to be installed.
This is currently being worked on in this PR: https://github.com/openshift/openshift-ansible/pull/999/files
Verify this bug with atomic-openshift-utils-3.0.18-1.git.0.a3e601b.el7aos.noarch Some more guidance text about what is expected in the following input and the roles management in Host Configuration: You must now specify the hosts that will compose your OpenShift cluster. Please enter an IP or hostname to connect to for each system in the cluster. You will then be prompted to identify what role you would like this system to serve in the cluster. If only one Master is specified, an etcd instance embedded within the OpenShift Master service will be used as the datastore. This can be later replaced with a separate etcd instance if desired. If multiple Masters are specified, a separate etcd cluster will be configured with each Master serving as a member.
