docker - 提交更改后无法运行容器

Question

只是基本和简单的步骤说明了我的尝试:

1. docker pull mysql/mysql-server
2. sudo docker run -i -t mysql/mysql-server:latest/bin/bash
3. yum 安装 vi
4. vi/etc/my.cnf -> bind-address=0.0.0.0
5. 退出
6. docker
7. docker commit new_image_name
8. docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=secret -d new_image_name

docker ps -a 状态 - 退出 (1)

请告诉我我做错了什么。

Answer 1

与其尝试修改现有图像，不如尝试使用(用于测试)MYSQL_ROOT_HOST=%。
这将允许从任何 IP 进行 root 登录。 (如 docker-library/mysql issue 241 中所见)

sudo docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_ROOT_HOST=% -d mysql/mysql-server:latest

README 提到:

By default, MySQL creates the 'root'@'localhost' account.
This account can only be connected to from inside the container, requiring the use of the docker exec command as noted under Connect to MySQL from the MySQL Command Line Client.
To allow connections from other hosts, set this environment variable.
As an example, the value "172.17.0.1", which is the default Docker gateway IP, will allow connections from the Docker host machine.
