Might be dangerous if any of the keys or values in the JSON contain the space character, why not something like this:

Suggested change

	SNAPSHOT=$(echo "$REDUCED_SNAPSHOT" | tr -d ' ' | tr -d '\n')
	echo "$SNAPSHOT" > "${SNAPSHOT_PATH}"
	echo "$SNAPSHOT" | jq -c . > "${SNAPSHOT_PATH}"

fixed. thanks

I see this now:

echo "$REDUCED_SNAPSHOT" | jq .
SNAPSHOT=$(echo "$REDUCED_SNAPSHOT" | tr -d ' ' | tr -d '\n')
echo "$SNAPSHOT" | jq -c . > "${SNAPSHOT_PATH}"

I think @zregvart meant this:

# for displaying
echo "$REDUCED_SNAPSHOT" | jq .
# for saving
echo "$REDUCED_SNAPSHOT" | jq -c . > "${SNAPSHOT_PATH}"

Honestly, I would just do something like this:

echo "$REDUCED_SNAPSHOT" | jq '.' | tee "${SNAPSHOT_PATH}"

I don't really think we need to save the reduced snapshot as a compacted json.

ok adjusted. but I seem to remember an issue whereby I needed to remove the line feeds...

For tidiness I'd probably suggest:

COPY --from=build /build/hack/reduce-snapshot.sh /usr/local/bin

(Not super important, also I realize I'm too slow and its merged already.)
