cert-manager supports the Lets Encrypt DNS challenge, which supports wildcard certs: https://cert-manager.io/docs/ https://cert-manager.io/docs/ It's a little bit of one time setup and then easy-peezy SSL automatically for all your services.
Do note that you need a DNS provider with a good API to programmatically control it (the DNS challenge requires setting a special txt record that Lets Encrypt verifies). Read the docs to learn more, but most of the big ones (AWS Route 53, Cloudflare, etc.) should be fine.
