The mesh-lab container goes with its Dockerfile, build bases, bus credential and state directory. What the image installed — git, make, python, file, iproute2, sudo, npm, go and the incus client — are packages of the machine, and docker and incus are reached through their sockets as the runtime's account. The forge is an operator's setting, which reaches a file and never a bundle's words, so the tools read it from the env-file the mesh already fills, at each call; that is the one code change.
