It’s not that different than other media. There is really good analysis out there but you have to really go out of your way to avoid the bullshit. The stuff that really gets eyeballs is the low hanging, drama oriented, sound-byte-y stuff.
Who even has interest in tracking this?
I think the container piece is probably the least of your concerns here honestly. The biggest thing you’ll want to focus on is the ingress networking layer, but that won’t really be any different than if you were running the app normally. Generally exposing ports from your home network to the internet is not a great idea, and you try to use something like cloudflare or get a cheap cloud VPS with a reverse proxy connected to the container host via VPN.
But for general container security practice, what you mentioned is good. You could also look at the Docker CIS Benchmark for more good security practices. And container scanning tools like trivy or anchore syft/grype to identify vulnerabilities in your containers. But again this is secondary to the networking layer in my opinion.
I don’t find the designation to be that much of a thing. There are former players that are great and there are former players who are completely awful clickbait clowns. Same is true for non former athletes.
The good former pros definitely have a valuable perspective though I think there’s also something to be said for a bit of a removed perspective.
