+
+Universal Control Plane can pull and run images from any image registry,
+including Docker Trusted Registry and Docker Store.
+
+If your registry uses globally-trusted TLS certificates, everything works
+out of the box, and you don't need to configure anything. But if your registries
+use self-signed certificates or certificates issues by your own Certificate
+Authority, you need to configure UCP to trust those registries.
+
+## Trust Docker Trusted Registry
+
+To configure UCP to trust a DTR deployment, you need to update the
+[UCP system configuration](ucp-configuration-file.md) to include one entry for
+each DTR deployment:
+
+```
+[[registries]]
+  host_address = "dtr.example.org"
+  ca_bundle = """
+-----BEGIN CERTIFICATE-----
+...
+-----END CERTIFICATE-----"""
+
+[[registries]]
+  host_address = "internal-dtr.example.org:444"
+  ca_bundle = """
+-----BEGIN CERTIFICATE-----
+...
+-----END CERTIFICATE-----"""
+```
+
+You only need to include the port section if your DTR deployment is running
+on a port other than 443.
+
+You can customize and use the script below to generate a file named
+`trust-dtr.toml` with the configuration needed for your DTR deployment.
+
+```
+# Replace this url by your DTR deployment url and port
+DTR_URL=https://dtr.example.org
+DTR_PORT=443
+
+dtr_full_url=${DTR_URL}:${DTR_PORT}
+dtr_ca_url=${dtr_full_url}/ca
+
+# Strip protocol and default https port
+dtr_host_address=${dtr_full_url#"https://"}
+dtr_host_address=${dtr_host_address%":443"}
+
+# Create the registry configuration and save it it
+cat <<EOL > trust-dtr.toml
+
+[[registries]]
+  # host address should not contain protocol or port if using 443
+  host_address = $dtr_host_address
+  ca_bundle = """
+$(curl -sk $dtr_ca_url)"""
+EOL
+```
+
+You can then append the content of `trust-dtr.toml` to your current UCP
+configuration to make UCP trust this DTR deployment.
