Create self-sign CA certificate
Why I do this? I use GitLab for internal purpose (don’t face to the Internet.) In order to using CI/CD integration with Docker, I should use “valid” TLS certificate, so I created an self-sign certificate.
Instructions Create a private key. openssl ecparam -out mygitlab.com.key -name prime256v1 -genkey Create a config file mygitlab.cnf for crate self-sign certificate. [ req ] default_keyfile = /path/to/the/key/file/mygitlab.com.key default_md = sha256 prompt = no distinguished_name = gitlab_dn x509_extensions = gitlab_ext [ gitlab_dn ] commonName = mygitlab.
