docker的安装太简单了就不说了哈。

centos7搭建docker，docker搭建oracle-12c

1、修改镜像下载地址。

因为是国内的所以我修改了国内的镜像下载源地址。

vi /etc/docker/daemon.json

[root@k8s-client1 ~]# cat  /etc/docker/daemon.json  
{
         "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

2、下载镜像文件。

2.1 查询镜像#docker search oracle

docker pull docker.io/truevoly/oracle-12c

下载好了使用docker images查看

3、启动数据库

3.1 启动前注意内容大小。我这里用了8G，

3.2 注意硬盘大小至少需要4G的预留

docker run -d -p 8080:8080 -p 1521:1521  docker.io/truevoly/oracle-12c

[root@k8s-client1 ~]# docker logs -f fafcbedc8b85

4、验证数据库可用性

查看容器的ID

[root@k8s-client1 ~]# docker ps 
CONTAINER ID        IMAGE                           COMMAND             CREATED             STATUS              PORTS                                            NAMES
fafcbedc8b85        docker.io/truevoly/oracle-12c   "/entrypoint.sh "   20 minutes ago      Up 20 minutes       0.0.0.0:1521->1521/tcp, 0.0.0.0:8080->8080/tcp   gracious_newton

进入容器

[root@k8s-client1 ~]# docker exec -it fafcbedc8b85 /bin/bash
root@fafcbedc8b85:/# 

切换数据库用户

root@fafcbedc8b85:/# su oracle
oracle@fafcbedc8b85:/$ 

进入数据库

oracle@fafcbedc8b85:/$ $ORACLE_HOME/bin/sqlplus / as sysdba
