The way it's worded, it makes it sound like it's a task you need to perform, however the installation process takes care of it for you. It's still worth noting what is taking place, but it should be reworded to make things more clear. Duplicate GH Issue here: https://github.com/openshift/openshift-docs/issues/1017 The Quick Installation topic now has the following Note admonition to explain what automatically happens for masters: https://docs.openshift.com/enterprise/latest/install_config/install/quick_install.html#quick-before-you-begin "By default, any hosts you designate as masters during the installation process are automatically also configured as nodes so that the masters are configured as part of the OpenShift SDN. The node component on the masters, however, are marked unscheduable, which blocks pods from being scheduled on it. After the installation, you can mark them schedulable if you want." And the Advanced Installation topic now has the following subsection under "Configuring Ansible" to make it more clear how you can control this at installation time: https://docs.openshift.com/enterprise/latest/install_config/install/advanced_install.html#marking-masters-as-unschedulable-nodes |
