Install oracle products on docker

现在我们可以从oracle的container registry中下载pre-installed/pre-built image来进行安装。安装非常简单，大大简化了工作量。预制的image包括k8s，Oracle的数据库（标准版、企业版、单实例、集群）、中间件（BI、weblogic、coherence、tuxedo、soa、webtier、odi、fmw）、操作系统、Java、MySQL（社区办、企业版）等等。本部描述的是在Oracle7上安装docker，然后部署MySQL企业版的一个用例。

首先在Oracle7上安装docker
[root@xd07dbm01 ~]# cd /etc/yum.repos.d/
[root@xd07dbm01 ~]# wget http://yum.oracle.com/public-yum-ol7.repo
[root@xd07dbm01 ~]# vi public-yum-ol7.repo
[ol7_latest]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=http://yum.oracle.com/repo/OracleLinux/OL7/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

[ol7_UEKR4]
name=Latest Unbreakable Enterprise Kernel Release 4 for Oracle Linux $releasever ($basearch)
baseurl=http://yum.oracle.com/repo/OracleLinux/OL7/UEKR4/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

[ol7_addons]
name=Oracle Linux $releasever Add ons ($basearch)
baseurl=http://yum.oracle.com/repo/OracleLinux/OL7/addons/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

[root@xd07dbm01 ~]# yum install docker-engine -y
[root@xd07dbm01 ~]# systemctl start docker
[root@xd07dbm01 ~]# systemctl enable docker

[root@xd07dbm01 ~]# systemctl status docker

用账号登录Oracle的container registry，并下载相关镜像
[root@xd07dbm01 ~]# docker login container-registry.oracle.com

下面是在docker中如何运行MySQL8.0.13企业版的日志
docker run --name=mysqla -d container-registry.oracle.com/mysql/enterprise-server:8.0.13
docker ps
docker logs mysqla 2>&1 | grep GENERATED
docker exec -it mysql1 mysql -uroot -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'oracle';
docker exec -it mysqla bash
ls /var/lib/mysql
docker stop mysqla
docker rm mysqla

[root@xd07dbm01 ~]# docker run --name=mysqla -d container-registry.oracle.com/mysql/enterprise-server:8.0.13

其他有用的docker工具，比如Docker Toolbox(包含boot2docker，kitematic)，不是Docker for windows
