前言
昨天有一位搞 DBA 同学问我会不会用 Docker。Ta 想要在上面跑一个 Oracle 实例。整个过程非常流畅，写篇文章备用。 ：)
ENV
# lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Codename: xenial
# Oracle Version Package
linuxx64_12201_database.zip
Install docker
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" | sudo tee /etc/apt/sources.list.d/docker.list
apt-get update
apt-get install docker-engine -y
Download Oracle Docker Image
Docker Images from Oracle https://github.com/oracle/docker-images
cd ~
git clone [email protected]:oracle/docker-images.git oracle-images
Download & Upload Oracle
Download page http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
when you download the package, upload it to the ${docker-images}/OracleDatabase/dockerfiles/x.x.x.x/
du -sh ./oracle-images/OracleDatabase/dockerfiles/12.2.0.1/* | grep zip
3.3G ./oracle-images/OracleDatabase/dockerfiles/12.2.0.1/linuxx64_12201_database.zip
接下来，开始无脑安装。因为有一些依赖包需要安装，请确保 REPO & 网络可用。
Build Docker Image
# bash oracle-images/OracleDatabase/dockerfiles/buildDockerImage.sh -v 12.2.0.1 -e
# bash oracle-images/OracleDatabase/dockerfiles/buildDockerImage.sh
Usage: buildDockerImage.sh -v [version] [-e | -s | -x] [-i]
Builds a Docker Image for Oracle Database.
Parameters:
-v: version to build
Choose one of: oracle-images
-e: creates image based on 'Enterprise Edition'
-s: creates image based on 'Standard Edition 2'
-x: creates image based on 'Express Edition'
-i: ignores the MD5 checksums
* select one edition only: -e, -s, or -x

整个过程分16步自动完成，具体完成时间取决于系统环境配置。
成功的日志类似如下的：
