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.
The bottom of Docker is a boot file system, Bootfs.The second layer is the root filesystem rootfs, located on the boot file system.In the traditional Linux boot process, the root filesystem is first read-only and is switched to read-write mode when the boot finishes and the integrity check is completed. But in Docker, the root filesystem is always read-only, and Docker
When we set up the Docker cluster, we will solve the problem of how to collect the log Elk provides a complete solution this article mainly introduces the use of Docker to build Elk collect Docker cluster log

Elk is made up of three open source tools , Elasticsearch, Logstash and kiabana

1. Docker Container Restart policy
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.

Docker-compose is a tool used to define and run complex applications in Docker. For example, to define multiple containers in a yum file, you can use only one line of command to make everything ready and run.

Restart the server, previously able to run the Docker network applications can not be opened normally.
Because of the use of CENTOS7, so speculation is likely to be a iptables problem.

In the previous example, the communication between the container and the container is done through the IP address in the network, which is obviously unreasonable, because the IP address may change when the container is started, and it is also more difficult to remember.
The solution to this problem is to use a network alias, the container is allowed to be alias on the network, and the alias can be directly accessed in the network, which is similar to t
Docker intranet: Docker-registry with Nginx SSL on CentOSSince Docker-registry is also a software application, the easiest way to do this is to use the officially provided image registry that has been deployed. The official documentation also gives suggestions for running sudo docker run -p 5000:5000 registry commands

Docker service is a declarative, scalable, load-balanced application. Docker service is a user-oriented application, while Docker swarm is an IT-oriented node cluster.
Docker service is often run on the basis of Docker swarm.
