Some Questions about learning How do I heat update mirrors (images)? (You can quickly start or destroy the container.) This time is almost real-time. How to hot update the game suit? The advantage is that the environment of each application is independent of each other, even if a container crashes will not affect other containers; How do you maintain each container using ports? (Method 1 is written in dockerfile, not flexible; Method 2
and Docker, there is indeed a history. The story begins in February 2013, when the American DotCloud company released a new Linux container software Docker and set up a website to publish its first demo version (see Docker's first official blog). And almost at the same time, in March 2013, California, the young handsome boy Alex Polvi is in his garage to start h
mirror, package your project jar, startup command (assumed to be shell script) to build a new mirror. You can use Dockerfile in the packaging mode.This practice may be considered:Place the project jar package under a mapping path (for example,/root/software/above), in the startup script, copy the jar package to the work path, and then start. This ensures that the base mirror for your project is sure to run (because there is an initial jar package und
and management Docker container-based mechanism can be easily deployed. A docker container can be executed on a local host or on a virtual machine, whether local or cloud. Rapid deployment of docker and lightweight features make it easy to manage loads. You can quickly start or destroy containers. This time is almost

A few days ago encountered such a business scenario, the database runs in the Docker, the Docker city is UTC so it is 8 hours away from the Beijing time. However, you cannot rerun a container, only to ensure that the database is running, and to copy the host's time zone to the Docker container. Very distressed, First I change the host's time zone to CST Beijing

Three major docker components: container and docker1. containers are another core concept of Docker. Simply put, containers are one or more applications that run independently and Their runtime environments.
