+docker pull jenkins/jenkins:lts
+docker run -p 8080:8080 -p 50000:50000 --network jenkins --hostname jenkins jenkins/jenkins:lts
+```

+```
+
+# 3.1 ssh into the devenv container, and start nginx
+```
+docker exec -it devenv /bin/bash
+```
+Then from within the container run:
+```
+/etc/init.d/nginx start
+```
+
+## 4. Configure devenv container as docker-slave
