Greetings to all,
I have implemented open source docker to my virtual machines. It all works fine, but I would like to finish the whole procedure following this link:
Since I managed to do it with self signed certificate, the question I have is the following - would a “real” but “cheap” SSL certificate that can be obtained from trusted source (those usually cost ~10$ per year), with the assumption that I have static IP address and domain name tied to that address, be sufficient to secure the registry and Docker access in general?
That is, if I have static IP x.x.x.x and SSL for foo.bar.com that would be machine that Docker is installed on, can I simply buy one of those low cost certificates (and use foo.bar.com domain as CN), or something more expensive has to be purchased?
Thank you in advance for any hint,
