Document URL: https://access.redhat.com/documentation/en/openshift-enterprise/3.1/installation-and-configuration/chapter-2-installing#prerequisites-1 Section Number and Name: 2.2.2. System Requirements Describe the issue: Documentation describes minimal hardware required for a master or node however there is no mention of the minimal number of masters/nodes in a supported environment, or whether all of these components can co-exist on a single node Suggestions for improvement: provide details about minimal number of masters/hosts and supportability of all-in-one environments
@Evgheni -- Does this new section satisfy your issue? https://docs.openshift.com/container-platform/3.6/install_config/install/planning.html#environment-scenarios Michael
Hi Michael, The new section provides good environment examples, however there is no guidance on why one should be chosen over the other. Also, the question from #0 is not answered: are all-in-one environments possible?
Added new section to https://docs.openshift.com/container-platform/3.6/install_config/install/planning.html#environment-scenarios: Single Master and Nodes on One System OpenShift Container Platform can be installed on a single system for a development environment only. An _all-in-one environment_ is not considered a production environment. Also, added a link back to the Sizing section to help users determine which environment to use. Use these scenarios as a basis for planning your own cluster, based on your xref:sizing[sizing] needs. https://github.com/openshift/openshift-docs/pull/6345/files
Jianlin -- Please take a look at what I added.
Most seem good to me, move to "VERIFIED". One very minor issue, should correct to "Nodes" to "Node", right? also leave a comment in the PR, once fixed, pls merge it directly.
Thanks for updating the doc, Michael. Looks good to me!
