Docker basic commands for mirroring, containers, warehouses
Mirror
1. Get Mirror
$ Docker Pull dl.dockerpool.com:5000/ubuntu:14.04
Dl.dockerpool.com for registration server, 5000 for port number, Ubuntu for warehouse name, 14.04 for mirror and version number
2. View mirror Information
Lists all mirrors that are already present on the local host
Change changes information
Mirror1. Get the mirrored Docker pull dl.dockerpool.com:5000/ubuntu:14.04 (dl.dockerpool.com is the registered server, 5000 is the port number, Ubuntu is the warehouse name, 14.04 is the image is the version number ) 2. View the image information Docker images (list all mirrors that are already in the local host) change the changes information Docker tag Dl.dockerpool.com:

String expressions are not computed.Mysql does not have functions similar to eval. maybe you can write For your example, you can writeSELECT substring_index (a, '*', 1) * substring_index (a, '*', 2), '*',-1) * substring_index (, '*', 3), '*',-1)From (select REPLACE ('500x

/CONFIG.D directory. Nginx link to registry container. Creates a registry container based on Registry:2 image, exposes container 5000 ports to host 5000 ports, uses environment variables to indicate the root directory using/data, and mounts the data/folder under the current directory to the/data directory of the container. All also need to create nginx and data folders in the current directory:

2. Deploying registry
Get the image of registry using the Docker pull command

Use Docker run to launch a container using the downloaded registry image

different, they are behind Nat; otherwise, they are behind Nat. To detect different types of NAT, the STUN Protocol defines message attributes and requires the server to have different actions, such as using different IP addresses and ports when sending responses, or changing ports. The STUN Protocol may be effective for Nat, but it is powerless for the firewall, because the firewall may not open the UDP port.
Nat category
Stun roughly divides NAT into four types: Full cone, restricted cone, po

Mysql transactions, concurrency issues, lock mechanisms, mysql transactions1. What is a transaction?
A transaction is a combination of one or more database operation statements. It has four features: ACID.
Atomicity
Isolation: transactions are independent of each other and do not interfere with each other.
Consistency: After the database changes its status correctly, the consistency constraints of the database are not damaged.
Persistence: the transaction commit result, which is permanently stor
When the Docker Registry V2 comes out, it's really good to be simple and practical, but when you change port 5000 to something else, or use a domain name binding, it's a mistake. Here is a detailed record of the process of your own experience.First, the installation of Docker Registry V2 (distribution).Here I chose to use the official provided image to install, perhaps you will feel that it is easy, dismissive. However, for an OPS person, the attentio
different regions, there must be a solution to achieve interconnection between the two, so the atm lane technology came into being. By using LANE, the ATM network can simulate the work of the LAN, so that multiple LAN can be connected to the ATM network without any modification. ATM is responsible for bridging, which is completely transparent and seamless for users. It seems to work in a pure Ethernet environment, as shown in figure 2.
The configuration process of LANE is complicated, and the
