I looked at the documentation and there doesn’t seem to be any info about getting an SSL certificate for a docker-compose environment.
Also in the paid SSL section is just mentions get your certificate bundle. This usually requires creating a CSR first and there is no mention on how to do that? How do I do it on a docker-compose install?
A CSR-Request technically has nothing to do with Zammad as an application and thus is not covered by the documentation.
Usually you’d use openssl for that, I googled that for you and picked a random site that fit:
If you’re not too firm with linux, you may want to consider using SaaS instead of a on premise installation. The docker installation method is easy to bring up, however, requires knowledge in that field and thus might not be suitable for you.
