Looks ok, any chance to add a new test to cover that behavior?

Any update on this? This was a good PR and necessary to support docker secrets.

Is there a way to help review/merge this ?
I would really like to use secrets in my setup.

@j0k3r @Kdecherf, gentle ping to get this reviewed. It would be great to have support for Docker secrets!

Is there a chance that this will get merged at some point?

"coming weeks" 😬

I'll dedicate some time next month to review this, sorry for taking this long

Missing some quoting here and [[ is bash-specific. This is sh, so maybe replace this whole block with something like:

for n in $(LC_ALL=C awk 'BEGIN {for (n in ENVIRON) if (n ~ /^[0-9A-Z_]+__FILE$/) print n}'); do
	if ! eval "${n%__FILE}=\$(cat -- \"\$$n\") && export ${n%__FILE}"; then
		printf 'Failed to read $%s\n' "$n" >&2
		exit 1
	fi
done
