Precisely. I've been implementing some kind of blue-green deployment with both systemd and dockerd, but it was an imperfect and incomplete solution. Kamal put much more effort into it and it seems more convenient and reliable (but I haven't tried it yet in production).
Ah yes my favourite thing to have to do, rolling my own deploys and rollbacks.
It’s stuff like this that’s just a thousand papercuts that dissuades me from using these “simpler” tools. By the time you’ve rebuilt by hand what you need, you’ve just created a worse version of the “more complex” solution.
I get it if your workload is so simple ir low requirement that zero-downtime deploys, rollbacks, health/liveness, automatic volumes, monitoring etc are features you don’t want or need, but “it’s just as good, just DIY all the things” doesn’t make it a viable alternative in my mind.
Sure but Kumal getting all those features means it strays close to Kubernetes in complexity and it quickly because "Why not Kubernetes? At least that is massive popular with a ton of support."
