Docker 数据持久化的三种方式小结

root@prometheus204:/var/lib/docker/volumes/for_nginx/_data# echo hello,123 > index.html 
root@prometheus204:/var/lib/docker/volumes/for_nginx/_data# 
# 访问nginx 显示 hello，123

-v ${local_path}:${docker_path} 

运行容器并设置挂载（正常方式）
docker run --name mynginx1 -d -p 80:80 \
--mount type=bind,source=/home/docker/volumes/nginx,target=/usr/share/nginx/html \
nginx:1.23.3
# 运行容器并设置挂载（-v方式）简写
docker run --name mynginx1 -d -p 80:80 \
-v /home/docker/volumes/nginx:/usr/share/nginx/html \
nginx:1.23.3

  # 挂载方式运行容器
docker run --name m1nginx -d --mount type=tmpfs,target=/usr/share/nginx/html nginx:1.23.3
# 进入容器
docker exec -it m1nginx /bin/bash
# cd到具体目录
cd usr/share/nginx/html/
# 创建test.html文件
echo "container write info" > test.html
