What process creates the stylesheet assets during build, e.g. /stylesheets/color_definitions_dark_1_1_603243e2b6c0b7xydx234the00538538bd705.css I’m assuming this is the process of bundling? What might be going wrong if these are missing? Should these start to exist as part of starting ember-cli o…

Stylesheets are built by the rails app on-demand, so in theory you don’t need to do anything manually. Running bin/rake assets:precompile will compile them eagerly, which can be useful if you want to create an optimised docker image for rolling out to multiple hosts.

Yep, exactly. These things also tend to be cached in postgres/redis so they only need to be generated by the first app container to receive a request. The other containers can then cheaply fetch the compiled version from redis/postgres and write it to the filesystem.
