Use a lightweight and flexible VM of the Docker container to take over the dependency on hell. Learn how Docker is based on LXC technology to make apps portable and independent by packaging applications in containers. Imagine that you can easily package the application and its dependencies, and then test the labels in other development and testing scenarios:
Docker is an open-source engine that makes it easy to create a lightweight, portable, self-sufficient container for any application. Developers who compile tests on notebooks can be deployed in batches in a production environment, including VMS (virtual machines), bare metal, OpenStack clusters, and other underlying application platforms.Docker is typically used for the following scenarios:Automated packagi
When Docker creates a container, it uses the bridge network by default, assigning its own IP and not allowing itself to be specified.In the actual deployment, we need to specify the container IP, not allow its own IP, especially when building a cluster, fixed IP is required.We can create our own bridge network: MyNet, when you create a

This is a creation in Article, where the information may have evolved or changed. Before Docker 1.9 was born, there were roughly three container communication scenarios across multiple hosts, such as: 1. Port mapping The port P of host A is mapped to Port P ', which is the network space listener of container C, and is only available for applications and services
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
This is a creation in Article, where the information may have evolved or changed. The research on the container network has been interrupted for some time due to the reasons for the exchange of work in 2016. With the current project to kubernetes application in depth, I feel that before the shallow understanding of the container network is not enough, the container
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.. Container virtualization refers to the application of packaging in the OS to run in the form
Objective 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.

The last section mentions that when the container is running, the data generated will not be in the write image, and re-starting the new container with this image will initialize the image and add a new read-write layer to hold the data. If you want to do data persistence, Docker provides data volume or data container
