Having a reproducible dev environment is great when everyone’s laptop is different and may be running different OSes, libraries, runtimes, etc.

Also docker has the network effect. If there was a good light weight tool that was better enough people would absolutely use it.

But it doesn’t exist.

In an ideal world it wouldn’t exist, but we don’t live there.

Docker and other containerization solved the “it works on my machine” issue

almost. there is still an issue with selinux. i just had that case. because the client develops with selinux turned off, the docker containers don't run on my machine if i have selinux turned on.

you miss an intermediate environment (staging, pre-prod, canary, whatever you want to call it) with selinux turned on.

i don't. the customer does. and they don't seem to care. turning selinux off works for them and they are not paying me to fix that or work around it.

Docker is that lightweight tool, isn’t it? It doesn’t seem that complex to me. Unfamiliar to those who haven’t used it, but not intrinsic complexity.
