sudo systemctl daemon-reload
sudo systemctl restart docker
执行命令拉取镜像文件
sudo docker pull dockerhub.icu/library/nginx
sudo docker image ls
sudo docker run hello-docker
sudo docker run redis
https://gist.github.com/y0ngb1n/7e8f16af3242c7815e7ca2f0833d3ea6
创建 docker-study 文件夹
创建 Dockerfile 文件 内容如下
FROM node:14-alpine
COPY index.js /index.js
CMD node /index.js
创建 index.js 文件
console.log('1111');
在目录下执行创建镜像文件命令
sudo docker build -t hello-docker .
导出镜像文件
sudo docker save -o hello_docker.tar hello-docker:latest
加载镜像文件
sudo docker load -i xxx
查看正在运行的镜像文件
sudo docker ps -a
sudo apt-get install docker.io
source /etc/bash_completion.d/docker.io
sudo docker.io version
另外一种安装方式
curl -sSL https://get.docker.com/ubuntu/|sudo.sh
sudo docker run ubuntu echo 'Hello world'
不用sudo 启动 docker
添加用户组
sudo groupadd docker
sudo gpasswd -a jkxy docker
sudo service docker restart
需要注销后重新登录才会生效
docker version
加载镜像文件
docker load -i xxx
加载后运行镜像文件
sudo docker run -d -p 6379:6379 redis
sudo docker run -d -p 5432:5432  -e POSTGRES_PASSWORD=admin -v /home/dc/postgresql/data:/var/lib/postgresql/data postgres:12.18-alpine
查看运行的进程
sudo docker ps
参考文档
https://blog.csdn.net/qq_40163617/article/details/107578706
启动本地docker
sudo systemctl start docker
启动docker中的某个镜像
docker start d7b67eb75ca2
sudo docker pull nacos-registry.cn-hangzhou.cr.aliyuncs.com/nacos/nacos-server
sudo docker pull <your-mirror>.mirror.aliyuncs.com/nacos/nacos-server
docker run -d --name nacos -p 8848:8848 -e PREFER_HOST_MODE=hostname -e MODE=standalone nacos/nacos-server
启动后，您可以通过访问http://localhost:8848/nacos来验证Nacos是否成功启动并运行正常
http://localhost:8848/nacos

问题排查，进入 docker 下载 的 centos7内部查看网络连接情况

ping www.baidu.com
ping 不通，修改 centos 的 dns
echo "nameserver 8.8.8.8" > /etc/resolv.conf
