In the 2013, the field of cloud computing became more of a noun "Docker". Known for its light weight, it's better to solve application packaging and deployment. We've been building IaaS before, but it's quite complex and complex to achieve unified functionality through IaaS. Encapsulation of particularity into the image to achieve an almost consistent deployment method, it is "
Docker official and individual published images due to a variety of reasons, such as version, more loopholes, has been counted Docker hub more than 30% of the official image contains high-risk vulnerabilities. In addition, the Docker pull download image is slow due to networ

Docker the expose command, you can map container internal ports by writing Dockerfile plus-p parameters, but for already running container, if you want to open up a new port, It's not easy to edit dockerfile and build again.
In fact, Docker itself uses iptables to do

Docker consists of three concepts:(1) The remote Repository is the aggregate of all the mirrors in the Remote Mirror Library (no entry operation).(2) The local image is the image pulled from the remote repository.(3) A local image is called a container (layered and operable).Docker
Implementation of dependency processing and parallel compilation of Docker image under shellRecently, when making a series of Docker image compilation scripts, I thought we could not speed up the parallel compilation, checked the data, and finally implemented the multiple Docker
