Recommendations & policies on Swap usage for idle memory-hungry applications?
I’m in a situation where I often have a lot of Docker containers - multiple applications, supporting databases, etc. Many of them are memory hungry containers like JIRA, GitLab, and the occasional Minecraft server. However, only a small handful are actually active at the same time, and the vast majority of them sit idle for most of the day. I estimate that out of a typical ~10GB memory usage, only ~2GB are actively being used at any given point in time.
The 16GB plan is out of my price range as a hobbyist, and feels quite wasteful for my use case. However, I have past successes with allocating a large swap area and letting idle applications page out when not being used. For example, would I be allowed to use the 4GB plan and allocate a 10GB swapfile?
