卸载删除干净

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \

                  docker-logrotate \
                  docker-engine

设置

$ sudo yum install -y yum-utils
 $ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

安装

$ sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

验证

$ sudo systemctl start docker
$ sudo docker run hello-world

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete 
Digest: sha256:13e367d31ae85359f42d637adf6da428f76d75dc9afeb3c21faea0d976f5c651
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

设置私有仓库

$ sudo docker pull registry
$ sudo docker run -id --name=registry -p 5000:5000 registry

配置insecure-registries

在/etc/docker/目录下配置daemon.json（如果文件不存在创建存在修改）

{
 "registry-mirrors": [
	 "https://mirror.ccs.tencentyun.com",
	 "https://kuamavit.mirror.aliyuncs.com",
	 "https://registry.docker-cn.com",
	 "https://docker.mirrors.ustc.edu.cn"
 ],
 "insecure-registries": [
 	"127.0.0.1:5000"
 ]
}

 push 默认是https模式的，配置127.0.0.1:5000则 docker push 镜像到这个地址的仓库采用http模式 。

重启

$ sudo systemctl daemon-reload
$ sudo systemctl restart docker.service

推送私有仓库

$ sudo docker pull redis
$ sudo docker tag redis:latest 127.0.0.1:5000/registry/redis:latest
$ sudo docker push 127.0.0.1:5000/registry/redis

curl命令验证一下

$ sudo curl http://127.0.0.1:5000/v2/_catalog

{“repositories”:[“registry/redis”]}

安装docker-compose

$ sudo yum -y install epel-release
 $ sudo yum update
 $ sudo yum install docker-compose

$ sudo docker-compose --version  
docker-compose version 1.18.0, build 8dd22a9

构建镜像

创建docker-compose文件执行(docker-compose 支持 docker-compose.yaml和docker-compose.yml)

$ sudo docker-compose up

创建Dockerfile文件使用docker build, 如构建tomcat
