Mostly just as a wrapper for Docker. The main issue I’ve run into is Docker’s union file system functionality doesn’t work when backed by ZFS, so disk usage can balloon out of control. I wouldn’t use this in production but don’t tell me how to live my life mom.
Beyond various Docker stacks I also have a Certbot container that uses Snap (sigh), and Hashicorp Vault container which runs as a vanilla SystemD service. I run Wireguard as part of my OPNSense VM. That’s something I would run in a VM since it’s exposed to the internet. I have an older MinIO and Concourse CI Docker Compose config that I’d love to run in LXC but I suspect that isn’t realistic.
Note on Vault, I haven’t been able to get mlock to work (used to prevent sensitive memory from being swapped). By all accounts it should just work in LXC, but since it isn’t and there’s no swap on the host I just turned it off. I may migrate Vault to a VM at some point.
I’m personally just interested in lightweight environments with good enough isolation and don’t break all the time over nothing. Docker mostly accomplishes that for me. LXC + Docker also mostly accomplishes that.
(My heart yearns for FreeBSD Jails but with decent tooling)
This is already said, but it cannot be too emphasized: This is not your fault. This is entirely on them. Three months is far too short to evaluate someone even if they were secretly unhappy with your performance. It might be worth talking to an employment lawyer, but likely you’ll have to take this on the chin. In the immortal words of the great Captain Picard: “It is possible to commit no mistakes and still lose. That is not a weakness; that is life.”
As everyone has said, you can expect to get questions about it, and I would definitely have a prepared, rehearsed statement. Some recruiters and hiring managers make a big deal about these sort of things, some won’t even care. Again: this is not your fault and do not be apologetic about it.
Five weeks is not a lot of time to get a new software job, even in a hot market. This is the unfortunate reality and I would start making contingency plans. If living in NYC remains a goal, then this is a setback but a far smaller one than it may seem right now. You don’t have a mortgage or a family hanging over your head. Moving back to NYC will be in play, likely sooner than you think.
Spending time on career development is a good idea. Something with a firm outcome like AWS Solutions Architect is also good. I have the associate certification which I started working on while at Amazon. It hasn’t really done much for me, but I’m not seeking positions where it would hold much weight.
