Journey To The Centre Of The Stack
· 5 min read
I first wrote this post in 2020 after spending several weeks containerising a legacy application I hadn't built and didn't fully understand. The experience was mostly archaeology — reading old config files, tracing hardcoded paths, figuring out what half a dozen processes actually did before touching anything. By the time I had a working Docker image, I'd earned it.
I'm updating it now because the journey has changed, and I think it's worth being honest about how.
