+# GUI's: Web Admin of Swarms and Registry
+
+What about web interfaces to control and manage Swarm?
+
+- [Docker Enterprise](https://www.docker.com/products/docker-enterprise) is Docker Inc's paid offering, which has GUI's.
+
+- [Portainer](https://portainer.io) is a popular open source web GUI for Swarm with node agents.
+
+- [Portus](http://port.us.org) is a SUSE-backed open source web GUI for registry.
+
+- Find lots of other Swarm tools in the [Awesome Docker list](http://awesome-docker.netlify.com).
+

+
+## Lets deploy Portainer
+
+- Yet another stack file
+
+.exercise[
+
+- Make sure we are in the stacks directory:
+  ```bash
+  cd ~/container.training/stacks
+  ```
+
+- Deploy the Portainer stack:
+  ```bash
+  docker stack deploy -c portainer.yml portainer
+  ```
+
+]
+
+---
+
+## View and setup Portainer
+
+- go to `<node ip>:9090`
+
+- You should see the setup UI. Create a 8-digit password.
+
+- Next, tell Portainer how to connect to docker.
+
+- We'll use the agent method (one per node).
+
+  - For connection, choose `Agent`
+
+  - Name: `swarm1`
+
+  - Agent URL: `tasks.agent:9001`
+
+- Let's browse around the interface
