使用MySQL官方映象，tag版本5.7

Dockerfile可以在這裡檢視 github.com/docker-library/mysql/tr...

準備映象

$ docker pull mysql:5.7
$ docker image ls
REPOSITORY   TAG       IMAGE ID       CREATED        SIZE
mysql        5.7       2c9028880e58   5 weeks ago    447MB

##建立容器
關於MySQL的映象使用，可以參考dockerhub hub.docker.com/_/mysql?tab=descrip...

關於Dockerfile Volume的定義，可以參考 github.com/docker-library/mysql/tr...

$ docker container run --name some-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d -v mysql-data:/var/lib/mysql mysql:5.7
02206eb369be08f660bf86b9d5be480e24bb6684c8a938627ebfbcfc0fd9e48e
$ docker volume ls
DRIVER    VOLUME NAME
local     mysql-data
$ docker volume inspect mysql-data
[
    {
        "CreatedAt": "2021-06-21T23:55:23+02:00",
        "Driver": "local",
        "Labels": null,
        "Mountpoint": "/var/lib/docker/volumes/mysql-data/_data",
        "Name": "mysql-data",
        "Options": null,
        "Scope": "local"
    }
]
$

資料庫寫入資料

進入MySQL的shell，密碼是 my-secret-pw

$ docker container exec -it 022 sh
# mysql -u root -p
Enter password:

Bye
# exit

建立了一個叫 demo的資料庫

檢視data volume

$ docker volume inspect mysql-data
[
    {
        "CreatedAt": "2021-06-22T00:01:34+02:00",
        "Driver": "local",
        "Labels": null,
        "Mountpoint": "/var/lib/docker/volumes/mysql-data/_data",
        "Name": "mysql-data",
        "Options": null,
        "Scope": "local"
    }
]
$ ls  /var/lib/docker/volumes/mysql-data/_data
auto.cnf    client-cert.pem  ib_buffer_pool  ibdata1  performance_schema  server-cert.pem
ca-key.pem  client-key.pem   ib_logfile0     ibtmp1   private_key.pem     server-key.pem
ca.pem      demo             ib_logfile1     mysql    public_key.pem      sys
$

其它資料庫

如果熟悉的話，也可以試試MongoDB hub.docker.com/_/mongo
