I. Introduction to Docker

The official website link: www.docker.com

Docker is an open source application container engine that allows developers to package their applications and dependencies into a portable image that can then be distributed to any popular Linux or Windows machine, as well as virtualization. Containers are completely sandboxed and have no interface with each other.

The relationship between an Image and a Container is similar to that between a class and an instance in object-oriented programming. An Image is a static definition and a Container is an entity of the Image runtime. Docker containers are created by Docker images.

Two, system requirements

The current installation system is CentOS 7Copy the code

Docker installation

1. Install Docker

Website tutorial docs.docker.com/engine/inst Docker setup…

Install the yum-utils package (which provides the yum-config-manager utility) and set up the stable repository. sudo yum install -y yum-utils sudo yum-config-manager \ --add-repo \ Ali cloud source address https://download.docker.com/linux/centos/docker-ce.repo or use sudo yum - config - manager \ - add - repo \ http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo (2). Sudo yum install docker-ce docker-ce cli containerd.io Install the latest version of DOCKER Engine and container: sudo yum install docker-ce docker-ce cli containerd.ioCopy the code

Uninstall old Docker

sudo yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate Docker-logrotate docker-engine or use the following method to list the related packages docker installed: Sudo yum list installed | grep docker delete the relevant installation package sudo yum - y remove docker - ce. X86_64 sudo yum - y remove Sudo rm -rf /var/lib/docker sudo yum remove docker docker-common docker-selinux docker-engineCopy the code

17. Docker run parameter Description

Docker run [OPTIONS] IMAGE [COMMAND] [ARG…]

OPTIONS are described as follows:

-a stdin: specifies the standard input and output types. The options are stdin, STDOUT, or STDERR. -d: Runs the container in the background and returns the container ID. -i: Runs the container in interactive mode, usually with -t. -p: specifies the port mapping. The format is as follows: Host (host) port: container port -t: reassigns a pseudo input terminal to the container. It is usually used together with -i. --name="nginx-lb": specify a name for the container; -- DNS 8.8.8.8: Specifies the DNS server used by the container. The default DNS server is the same as the host server. --dns-search example.com: specify the container DNS search domain name, which is the same as the host by default. -h "Mars ": specifies the hostname of the container. -e username=" Ritchie ": Set the environment variable. --env-file=[]: reads environment variables from specified files; --cpuset="0-2" or --cpuset="0,1,2": bind the container to the specified CPU; -m: sets the maximum memory used by a container. - net = "bridge" : specify the container's network connection type, support bridge/host/none/container: four types; --link=[]: Add link to another container; --expose=[]: Open a port or group of ports; --volume, -v: Binds a volumeCopy the code
