In this section, we will review the Docker UCP environment. We will be able to use either the web UI, the command line, or its published REST API. In this book, we will cover the web application interface and how to integrate our docker client command line with UCP.
First, we will introduce the web UI.
The web UI
The web UI will run on all manager nodes. We will use UCP's fully qualified domain name, which is associated with its virtual IP address. Port 443 will be used unless you manually configured a different one. If we open https://<UCP_FQDN>:<UCP_PORT> on our browser, we will access the UCP login page. If we have used autogenerated certificates, the browser will warn us about an untrusted CA. This is normal because UCP generates an internal CA automatically for us to sign all internal and external certificates. We can upload our corporate or private certificates into UCP.
