+# uc proxy
+
+Proxy a service port to a local port.
+
+## Synopsis
+
+Proxy a service port in the cluster to a local port on this machine.
+
+If the service runs multiple containers, the command connects to the first running and healthy one.
+If you don't provide a local port, the command picks a random one.
+
+The connection stays open for as long as the command runs.
