福尔曼 … 没有OpenVZ的?
Ah ... Foreman does not support OpenVZ containers.
OpenVZ is very efficient with computing resources. That means I can use lower-cost servers and pack them with 30 or more containers, as long as they all operate the same Debian operating system. That is a very small trade-off for the efficiency and cost savings offered by OpenVZ.
Perhaps I may need to continue using Proxmox with Puppet or find another provisioning tool. To be continued ...
