【openGauss】构建一个兼容Oracle模式支持创建package的openGauss的docker镜像

背景

openGauss 2.1.0版本,新增package类型的对象,可以像oracle一样创建package,参考此篇文章

《openGauss存储过程功能全面升级，支持PACKAGE,PLDEBUGGER等诸多新特性》

然而当你在自己的openGauss数据库中,运行此篇文章中创建package的命令,如下:

CREATE OR REPLACE PACKAGE PCK1 --包头，在包头内声明的变量存储过程等都为公有的，可以被外部访问 IS
public_var1 int:=1; --在包头声明的公有变量public_var1，可以被外部访问 procedure
public_proc1(col1 int,col2 int); --只在包头内声明的存储过程，因此为公有的，可以被外部访问。 END
PCK1; /

极有可能会收到一条报错信息

这是因为,你安装数据库的时候,可能没有配置此参数 “–dbcompatibility”,或者此参数不是配置的"A",而是默认的"PG"。

根据官方文档介绍CREATE DATABASE

DBCOMPATIBILITY [ = ] compatibilty_type 指定兼容的数据库的类型。
取值范围：A、B、C、PG。分别表示兼容O、MY、TD和POSTGRES。

我本地的第一个openGauss数据库使用的是官方的docker镜像,在github上查看它的docker构建脚本,可以发现它直接配置成了PG,而且没有作为docker容器的运行参数放出来。

if [ -n "$GS_NODENAME" ]; theneval 'gs_initdb --pwfile=<(echo "$GS_PASSWORD") --nodename=$GS_NODENAME --encoding=UTF-8 --locale=en_US.UTF-8 --dbcompatibility=PG -D $PGDATA'elseeval 'gs_initdb --pwfile=<(echo "$GS_PASSWORD") --nodename=gaussdb --encoding=UTF-8 --locale=en_US.UTF-8 --dbcompatibility=PG -D $PGDATA'fi  

所以如果要使用一个支持创建create package的openGauss的docker容器,必须修改这个构建脚本,再自行构建一个docker镜像。

下面以X86的数据库为例开始说明操作步骤

执行构建的步骤

1、准备一台已经安装好docker的linux服务器,而且是有外网的
2、下载仓库并解压enmotech-docker-opengauss

3、编辑entrypoint.sh文件,将所有的"–dbcompatibility=PG"替换成"–dbcompatibility=A",保存

4、下载数据库安装包openGauss-2.1.0-CentOS-64bit.tar.bz2,放到仓库目录的2.1.0文件夹下
5、修改docker环境的DNS并重启docker服务(防止apt-get失败),下面为此步的操作方式(参考):

vi /etc/docker/daemon.json

将以下内容保存进daemon.json文件内

{   "dns": ["8.8.8.8", "114.114.114.114"]    
}

6、在2.1.0目录新增一个sources.list文件,添加阿里云的apt源(防止官方源连不上),文件内容为

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe
multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main
restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/
bionic-security main restricted universe multiverse deb-src
http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted
universe multiverse deb http://mirrors.aliyun.com/ubuntu/
bionic-updates main restricted universe multiverse deb-src
http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted
universe multiverse deb http://mirrors.aliyun.com/ubuntu/
bionic-backports main restricted universe multiverse deb-src
http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted
universe multivers deb http://mirrors.aliyun.com/ubuntu/
bionic-proposed main restricted universe multiverse deb-src
http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted
universe multiverse

7、修改dockerfile_amd文件,在"COPY Oracle_Views_1.0.0.sql /tmp"下添加一行"COPY sources.list /etc/apt/"

8、授权buildDockerImage.sh为可执行"chmod 777 buildDockerImage.sh"
9、运行buildDockerImage.sh “./buildDockerImage.sh -v 2.1.0”
10、构建成功,运行容器

docker run --name opengauss --privileged=true -d -e GS_PASSWORD=Enmo@123 -p 5432:5432 opengauss:2.1.0

以下为构建时输出的信息以及最后运行容器成功的信息

[root@MiWiFi-R3G-srv enmotech-docker-opengauss-master]# ./buildDockerImage.sh -v 2.1.0
