Four example Dockerfiles named golang:1.25 while go.mod requires 1.26; the control plane's image takes GO_BASE from the manifest and these did not, so a build that could not fetch a newer toolchain failed at go mod download (found running the lab through the mesh).

# The bucket provisioner, as a module ships one.

# Built here so a machine can be given it by the mesh rather than by somebody putting a binary on

|
# it.

|
|
# **Not FROM scratch, unlike the postgres one, and the difference is the point.** This drives the
|
|
# store's own command line, so that client has to be in the image — a provisioner is allowed to
|
|
# know how to operate the thing it provisions.
|
|
#
|
|
# The client is copied from the vendor's own image rather than installed from a distribution:
|
|
# `apk add mc` on Alpine installs Midnight Commander, which is a different program with the same
|
|
# name, and the failure would be a provisioner that starts cleanly and cannot do anything.
|
|
# The Go it builds with is the one the manifest pins (build.on GO_BASE), passed by the Makefile and the
|
|
# build machine alike; the default only serves a hand build, and matches go.mod.
