Configuring Podman and Docker to trust the Certificate Authority

Podman uses two paths to locate the CA file, namely, /etc/containers/certs.d/ and /etc/docker/certs.d/.

Copy the root CA file to one of these locations, with the exact path determined by the server hostname, and naming the file ca.crt

In the following examples, replace hostname.example.com with {foreman-example-com} or {smartproxy-example-com}, depending on your use case.

You might first need to create the relevant location using:

# mkdir -p /etc/containers/certs.d/hostname.example.com

or

# mkdir -p /etc/docker/certs.d/hostname.example.com

For podman, use:

# cp rootCA.pem /etc/containers/certs.d/hostname.example.com/ca.crt

Alternatively, if you are using Docker, copy the root CA file to the equivalent Docker directory:
```
# cp rootCA.pem /etc/docker/certs.d/hostname.example.com/ca.crt
```

You no longer need to use the --tls-verify=false option when logging in to the registry:

$ podman login hostname.example.com

Username: admin
Password:
Login Succeeded!
