• Removing an image: docker-init -r -n my-image
• Linking a container to another container: docker-init -l -n my-container -n other-container
• Mounting a volume to a container: docker-init -m -n my-container -v my-volume
• Setting the storage driver for a container: docker-init -s -n my-container -d my-driver
• Setting the CPU limit for a container: docker-init -c -n my-container -l 2
• Setting the memory limit for a container: docker-init -g -n my-container -l 4G
• Setting the user for a container: docker-init -u -n my-container -u my-user
• Setting the network for a container: docker-init -w -n my-container -n my-network
• Adding a host to a container: docker-init -a -n my-container -h my-host
