You shall need sudo access for all of these.

You might want to create a new user do as following

useradd <username>
passwd <username>
usermod -aG wheel <username>

// Update the machine first ? I like to do that often. You can skip it.

You need to know about:

mvn dependency:tree
mvn dependency:analyze

	//This might come handy when you want to inspect the fs of a dead container
	//or want to debug why it was not coming alright.
	docker container run -it --rm --entrypoint=/bin/bash <image id>

	// To transfer images from one host to another
	docker save <image id> > /tmp/image.tar
	docker load < /tmp/image.tar
