Where does greenlock-express saves lets-encrypt certificates?
I have just ran into the same problem.
You can set up the path to the certificates using this command:
npx greenlock defaults --store greenlock-store-fs --store-base-path <path_to_certificates>All that's left is to mount your volume.
I'm also pointing my configDir: '<path_to_certificates>' there as the config does not seem like something you want to commit. If I ran out of certificates, I'll let you know.
