Docker is useless and unnecessary for small and medium-sized enterprises to build Paas. It is a little less useful to use it as a personal sandbox, I personally think that docker can be used as a standard development, testing, and production environment for small and medium-sized enterprises.I drew a simple figure:Docker occupies a small amount of resources. It is more than enough to deploy 100 containers o
In the traditional model, the development team completes the software development in the development environment, does the unit test itself, passes the test, ᨀ to the Code version Management library. Operation of the application deployment to the test environment, QA testing, no problem, notify the deployment of the release to the production environment. The above process involves at least three environments: development, testing, and production. The reality is that the development of self-test
Docker deployment Environment: CentOS release 6.5 (Final)1. Edit the Docker configuration file because the registry service we started is not secure and trustworthy. So we need to modify the Docker configuration file,[Email protected]]# vim/etc/sysconfig/Dockerother_args="--insecure-registry= 192.168.1.243:5000-h tcp://0.0.0.0:235-h unix:///var/run/docker.sock"2.

But in Docker, the root filesystem is always read-only, and Docker

The restart policy for Docker containers is a start-up strategy for production environments that can be ignored during the development process.
Docker container restarts are done by the Docker daemon and are therefore closely related to the daemon process.

What is the directive for port mapping.
Docker command: Docker run-p ip:hostPort:containerPort Redis
Use the-p parameter to map the host's port to the virtual machine.IP rep
Before the company's test environment, just start to build their own virtual machine, and then install Redis,nginx,mq,mysql,tomcat,jdk,marven, and Jekins. The front is still good, jekins is still a bit troublesome. And then after the mirror out, switch to another platform, a different IP, do a test environment alone. Then every time you deploy, connect to the Linux server via SSH, kill-9, then back up, restart the server, Fight the war pack, really upset people. Later with the Jekins, the develo
