The container is the second core concept of Docker, and the simple one is that the container is a running instance of the mirror, and the difference is that it has an extra writable file layer.

Server virtualization refers to the operating system and hardware to add a layer, called the hypervisor layer, the next control hardware, on the host operating system, operating system OS in file form, known as virtual machine, the main problem is the hardware utilization and flexibility of the problem, the common solution for VMware Vsphere,xen,kvm,hyper-v..

Today, in the Docker, we are able to easily package our applications with containers and deploy them on our servers and run them. However, talking about how to stop the Docker container in the running and terminate the program correctly is a very worthwhile topic to discuss.
In fact, in our daily projects,
Looking at the history of Docker, you'll find that Docker has been emphasizing the word "application", and Docker wants to provide containerized solutions for distributed applications.From the life cycle of the Docker application software, the development work appears to be before the
Wrote an article about Jenkins integrated Docker very early, using the cloudbees Docker Build and Publish plugin plugin. This article is done directly with the shell script, mainly this time there is a need to detect whether the harbor warehouse is already existing to build the image, if it exists to abandon the build, if not exist then build the image and upload

, then you need to use the-e lxc option to restart the Docker service process. With this option, the LXC Management container will be used again within the Docker. The easiest way to accomplish this task is to create the/etc/default/docker file (if it still does not exist) and add the following:
Docker_opts= "-E Lxc"
shared and reused between containers;
Changes to the data volume will be effective immediately;
Updates to the data volume do not affect mirroring;
The volume will always exist until no container is used.
The use of a data volume, similar to the mount operation of a directory or file under Linux.
To mount a local directory into a container

In front of our experimental environment there is only one Docker host, and all the containers are running on this host. However, in a real environment there will be multiple hosts, where containers are started, run, stopped, and destroyed, and related containers communicate with each other over the network, regardless of whether they are located in the same host.How do we manage this multi-host environment
Adjust the partition size of Rootfs in Docker
The main introduction here is to adjust the size of the rootfs within the container, Rootfs the default is 10G, we can increase the size by the following method.bash-4.1# DF-LHTFileSystem Type Size Used avail use% mounted onRootfs rootfs 9.8G 1.4G 7.9G 15%/Tmpfs tmpfs 921M 0 921M 0%/devSHM tmpfs 64M 0 64M 0%/dev/shm/dev/vdb xfs 100G 2.1G 98G 3%/etc/resolv.conf/d
