I'm trying to set up a docker local registry within my university network. Since they offer certificates from rediris I requested one, so I have now three different files:
- cert.pem
- intermediate.pem
- chain.pem
In addition to this, I kept my .key and .csr as well. Following the docker website example (https://docs.docker.com/registry/deploying/#get-a-certificate)
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt
I'm not able to comprehend how concatenate/transform those pem files into the domain.crt file I need, all my tries led to the docker local registry treating the cert as self-signed.
Thank you very much in advance and am really sorry if this question is dumb, my knowledge on system administration is minimal.
