启动DB2容器

docker run -d --name db2 -p 50000:50000 -e DB2INST1_PASSWORD=rootpwd -e LICENSE=accept db2:latest db2start

> docker run -d --name db2 -p 50000:50000 -e DB2INST1_PASSWORD=rootpwd -e LICENSE=accept db2:latest db2start
f5d6341be8ff3e0b2089266002e06ad964c1cb08c9b6e76562c30d29906f5f47

(1).-p 50000:50000 允许远程的客户端可以从50000 端口连接到数据库实例（端口映射，格式为：主机(宿主)端口:容器端口）.
(2).-d: 后台运行容器，并返回容器ID
(3).--name db2: 为容器指定一个名称
(4).通过指定 -e DB2INST1_PASSWORD=[数据库密码] 参数(注：此处设置的密码为rootpwd), 你可以为缺省的Db2实例用户db2inst1设置密码
(5).通过指定-e LICENSE=accept参数, 表示你接受了使用Db2软件的许可证协议

进入镜像并切换用户

docker exec -it db2 /bin/bash

(1).docker exec ：在运行的容器中执行命令
(2).-t :分配一个伪终端
(3).db2 是容器的名称

切换用户

> docker exec -it db2 /bin/bash    

[root@f5d6341be8ff /]# su db2inst1
[db2inst1@f5d6341be8ff /]$
