Of course you're not doomed! Don't worry. You could always do a side project that uses containerization and cloud hosting.

My first dev job was over 15 years in bare-metal hosting (RHEL) and this was one of my biggest weaknesses too. I didn't get penalized too badly for it in the end. I even got an interview with a company that specialized in some kind of Kubernetes based product. I didn't get an offer from them but I did get an offer soon after that from a 100% AWS-hosted product company. It probably helped that I had so many years of development experience and had learned the basics of docker and containerization tech generally, so I understood what it can do for you and I was able to talk about that stuff intelligently. I had run into all the usual pitfalls in bare metal devops over the years so I was looking forward to moving to docker/cloud based stuff.

Over a year later I'm still a bit more rusty than most of my coworkers on AWS stuff. But you can pick it up. If you teach yourself how to use containerization (e.g. docker) and get a feel for what the advantages are, what problems it solves, to the point where you can talk convincingly about how you're exited to get a chance to use it, I think you'll come across ok.
