Getting Let's Encrypt / Google Managed Certificates to Work With Vault

Has anyone managed to use Let’s Encrypt certificates with Vault? We currently have it set up with a self-signed cert which creates problems with browsers. We’d prefer to be able to use a valid 3rd party (Google managed) cert with it. Any ideas?

Yes we use it. My co-worker wrote a chef recipe, but it is tied to aws. That is 2 requirements (aws, chef) so it might not work for you. When the cert changes, we just restart vault.
