Where Docker relies on the host operating system, Vagrant includes the operating system within itself as part of the package. One big difference between Docker and Vagrant is that Docker containers run on Linux, but Vagrant files can contain any operating system. ... It just needs to run within a Linux virtual machine.

Docker runs containers on a single machine, while docker swarm orchestrates a collection of containers (and the communication between them) across a network, allowing you to join multiple 'host' machines together to create a resilient, redundant cluster.

4 Answers. Docker CE (Community Edition) is the simple classical OSS (Open Source Software) Docker Engine. Docker EE (Enterprise Edition) is Docker CE with certification on some systems and support by Docker Inc. Docker CS (Commercially Supported) is kind of the old bundle version of Docker EE for versions <= 1.13.

2 Answers. Virtual machine is the running instance while Template is compact copy of VM ( with baseline and factory settings), which can be stored anywhere. ... one can create copy from both VM and template but in VM you need to clone it and in case of template you need to deploy it.

Generally, Docker or any other container technologies are an enabler for PaaS services. Many PaaS platforms (Dokku, Pivotal, OpenShift, AWS, Elasticbeanstalk, etc.) use containers as a building block.

Hypervisor runs at baremetal level, i.e. it controls the execution at processor. From that perspective, OSes are the Apps running on top of Hypervisor. The docker daemon runs within an OS as a service and manages containers for you. So from docker perspective, containers are the apps running on your OS.

They are designed to function as application containers. ... They are limited to containing applications that are natively supported by the host operating system. In other words, Docker for Windows can only host Windows applications inside Docker containers, and Docker on Linux supports only Linux apps.

Docker exec executes a new command / create a new process in the container's environment, while docker attach just connects the standard input/output/error of the main process(with PID 1) inside the container to corresponding standard input/output/error of current terminal(the terminal you are using to run the command) ...

A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.

As to what the actual difference is between those two options - well that could go on to be a very long answer but essentially LVM deals with extents and has multiple additional layers of abstraction that clearly need to be considered during boot - whereas the standard Linux PT should be a lot more starightforward than ...

Docker is container based technology and containers are just user space of the operating system. ... In Docker, the containers running share the host OS kernel. A Virtual Machine, on the other hand, is not based on container technology. They are made up of user space plus kernel space of an operating system.

Less overhead. Containers require less system resources than traditional or hardware virtual machine environments because they don't include operating system images. Increased portability. Applications running in containers can be deployed easily to multiple different operating systems and hardware platforms.

So, you run Windows, Virtual Server runs as a program on top of Windows and any VM runs inside it. Hyper-V on the other hand is a HyperVisor, it sits at a very low level on the system and using a management interface, you communicate directly with it.
