If we already had node_modules in here, how was it copied through during the build of that one server? Does .dockerignore work differently from .gitignore in that way?

Yes 😞

.dockerignore

the patterns /foo/bar and foo/bar both exclude a file or directory named bar in the foo subdirectory of PATH or in the root of the git repository located at URL. Neither excludes anything else.
-- https://docs.docker.com/engine/reference/builder/#dockerignore-file

.gitignore

If there is a separator at the beginning or middle (or both) of the pattern, then the pattern is relative to the directory level of the particular .gitignore file itself. Otherwise the pattern may also match at any level below the .gitignore level.
-- https://git-scm.com/docs/gitignore#_pattern_format

Probably good to include the preceding / in .dockerignore to make the intent more explicit.

Could we make it something like this:

/server/node_modules
/server/npm-debug.log

/client/node_modules
/client/npm-debug.log

Actually, could that change be all we need? Then an errant node_modules directory wouldn't be copied through.

This would be an alternative approach, but I think with a blacklisting approach there is more scope for accidentally including unwanted files in the future.
