+## Cluster API with Docker
+
+When provisioning workload clusters using Cluster API with Docker infrastructure,
+provisioning might be stuck: 
+
+1. if there are stopped containers on your machine from previous runs. Clean unused containers with [docker rm -f ](https://docs.docker.com/engine/reference/commandline/rm/). 
+
+2. if the docker space on your disk is being exhausted 
+    * Run [docker system df](https://docs.docker.com/engine/reference/commandline/system_df/) to inspect the disk space consumed by Docker resources.
+    * Run [docker system prune --volumes](https://docs.docker.com/engine/reference/commandline/system_prune/) to prune dangling images, containers, volumes and networks.
