 1. Generate a certificate signing request (CSR).
 
    Adapt the values in the `-subj` option to reflect your organization. If you use an FQDN to connect your Harbor host, you must specify it as the common name (`CN`) attribute and use it in the key and CSR filenames.

 1. Generate an x509 v3 extension file.
 
    Regardless of whether you're using either an FQDN or an IP address to connect to your Harbor host, you must create this file so that you can generate a certificate for your Harbor host that complies with the Subject Alternative Name (SAN) and x509 v3 extension requirements. Replace the `DNS` entries to reflect your domain.

 1. Convert `yourdomain.com.crt` to `yourdomain.com.cert`, for use by Docker.
 
    The Docker daemon interprets `.crt` files as CA certificates and `.cert` files as client certificates.

 1. Copy the server certificate, key and CA files into the Docker certificates folder on the Harbor host. You must create the appropriate folders first.
