Docker Basic Concepts

Before using Docker, let's look at the core concepts of the next few Docker

Docker Daemon

The Docker engine is a daemon that runs in the background, and after we launch it, we can send Docker-related commands through the Docker client.

Docker Images

Docker image, this is similar to our image when installing Windows, but the image of windows, in the past we usually exist on the CD or USB flash drive, where the image we usually publish to the Docker Registry

Docker Containers

Docker container, after acquiring the Docker image, we can run the image, and a Docker container is launched that runs the program in the Mirror. If the Docker image is understood as a class, then the Docker container is an instance

Docker Client

Docker client, after we have installed Docker, we open the terminal to operate with Docker-related commands, which are the commands of the Docker client, and a rest API-based Docker client, rest APIs are typically used in the development of some Docker operations-based systems.

Docker Registry

Docker image Registry, the registry for Docker's official website is http://hub.docker.com. We can also build our own registration center.

These are the core concepts of Docker, let's look at how to use Docker to install Redis, Zookeeper, Mysql, and in the process, learn some common commands for using Docker client

Installation

Centos
Yum Install Docker
Systemctl Start Docker.service
Systemctl Enable Docker.service

Ubuntu 16.04

Basic use

ElasticSearch

Docker Pull docker.elastic.co/elasticsearch/elasticsearch:5.4.0
Docker run-p 9200:9200-e "http.host=0.0.0.0"-E "transport.host=127.0.0.1" docker.elastic.co/elasticsearch/ elasticsearch:5.4.0

Redis

Find Mirrors

Use the following command to search for a redis mirror in the Docker hub

docker search redis

Pull Mirror

docker pull redis:latest

List all Mirrors

docker images

Create and start a container

docker run -p 6379:6379 -v $PWD/data:/data  -d redis:latest redis-server --appendonly yes

Executing the above command, we created and started a Redis container using the redis:latest image, where

-P 6,379:6,379: Map the container's 6379 port to the 6379 port of the host

-V $PWD/data:/data: Mount data from the current directory in the host to the/data of the container

Redis-server--appendonly Yes: Execute the redis-server start command in the container and open the Redis persistence configuration

View Container

Docker PS

Connect a Redis Container

Use a Redis image to connect to a Redis container using the REDIS-CLI client

docker run -it redis:latest redis-cli -h 192.168.0.101

Zookeeper

Next we install zookeeper, we use the same method as Redis. Install directly with minimal steps and no more explanations

Find Zookeeper Images

docker search zookeeper

Pull Mirror

docker pull zookeeper

Create and start a container

docker run -p 2181:2181 -v $PWD/data:/data  -d zookeeper:latest

Using the ZOOKEEPRT image to create and start the container, we map the container's 2181 to the 2181 of the machine and also mount the data of the current directory to the container's/data
