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. Docker start or run always prompt for a similar error:No Chain/target/match by that name Google a bit, and some people actually encountered similar problems.Centos 7 of/etc/sysconfig/iptables files: *nat :P rerouting ACCEPT [

This article is from the "Knowledge Forest" 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

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

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 Image:A docker image is a read-only template, for example, an image can contain the Ubuntu operating system environment, which installs Apache or other applications that the user needs.Mirroring can be used to create Docker containers.

The goal of

Basic concepts: Container Container. Each container can be viewed as a standalone host. The creation of container usually has an image as its template. Analogy to a virtual machine can be understood as image is the mirror of the virtual machine, and container is a running virtual machine. A virtual machine image can create multiple running virtual hosts and be independent of each other. Note: Once created, container will persist if not removed with the RM command. So remember to de

Prerequisites for Linux installation Docker:Must be a 64-bit CPU-architected computer, Docker currently does not support 32-bit CPUs, running Linux3.8 or later kernel, CentOS kernel must be no less than 3.10; the kernel has to support an appropriate storage driver, which can be device Manager, Aufs, VFS, Btrfs, and one of the default driver device mapper; The kernel must support and open the Cgroup and namespace namespace features. Check Prerequisites

When you create a Docker container, you should have a new namespace (if you have a separate network), you can see the namespace through the IP netns command, but you can't actually see it.After checking the data, we found that IP netns can only view the network namespace below/var/run/netns. Unlike OpenStack Neutron, Docker automatically creates namespace names in this file and needs to be created manually.
