docker升级docker pull mysql:5.7.37异常
一、使用背景
我们在使用docker拉取mysql命令时，数据库服务器，网络未开通外网，拉取镜像失败
但是我们还是想用docker部署则可以通过以下方式获取
前提：环境网络通可以pull mysql镜像
[root@VM-20-10-centos opt]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ae0a0e631153 mysql:5.7.37 "docker-entrypoint.s…" 9 hours ago Up About an hour 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp mysql
[root@VM-20-10-centos opt]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql latest 7ce93a845a8a 4 weeks ago 586MB
mysql 5.7.37 82d2d47667cf 2 years ago 450MB
[root@VM-20-10-centos opt]# docker save -o 1.tar mysql:5.7.37
说明：其中 docker save -o 1.tar mysql:5.7.37 来自IMAGE
1、先保存镜像为tar文件
docker save -o 1.tar mysql:5.7.372、从tar文件加载镜像、上传至目标服务器
docker load -i 1.tar[root@VM-20-10-centos backup]# docker load -i 1.tar

3、初始化mysql
sudo docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7.37
说明：其中root至的是密码、mysql: 5.7.37拉去取镜像版本
4、执行结果
[root@VM-20-10-centos backup]# sudo docker run -p 3306:3306 --name mysql \
> -v /mydata/mysql/log:/var/log/mysql \
> -v /mydata/mysql/data:/var/lib/mysql \
> -v /mydata/mysql/conf:/etc/mysql \
> -e MYSQL_ROOT_PASSWORD=root \
> -d mysql:5.7.37

[root@VM-20-10-centos backup]# docker ps

二、FAQ拉取镜像密码
-e MYSQL_ROOT_PASSWORD=root \ 未生效 使用root登陆未生效，从其他服务器拉取的mysql镜像密码是123456使用123456登陆msyql成功进入
mysql> exit
Bye

好了，至于为什么不重要 重新修改个密码吧
还有的小伙伴甚至docker都下载失败看过来
