Setup of the environment¶
For this quickstart, we will need 5 machines (or 3, if running workload applications on your control-plane nodes).
Each machine should have at least 2 CPU cores, 4 GB of RAM, and a root partition larger than 40 GB.
For sizing recommendations depending on sample use cases, see the Installation guide.
For nodes operating behind a proxy, add the following lines to each cluster
http_proxy=http://user;pass@<HTTP proxy IP address>:<port> https_proxy=http://user;pass@<HTTPS proxy IP address>:<port> no_proxy=localhost,127.0.0.1,<local IP of each node>
Each machine should be accessible through SSH from your host. As part of the Deployment of the Bootstrap node, a new SSH identity for the Bootstrap node will be generated and shared to other nodes in the cluster. It is also possible to do it beforehand.
Each machine needs to be a member of both the control-plane and workload-plane networks, as described in Networks. However, these networks can overlap, and nodes need not have distinct IPs for each plane.
In order to reach the cluster-provided UIs from your host, the host needs to be able to connect to workload-plane IPs of the machines.
