全网独家：基于openeuler-20.03-lts底包构建opengauss数据库V5.0.1LTS的单机容器

近期想测试一下opengauss数据库，官网上单机容器部署只有x86-64平台CentOS 7.6和ARM64平台 openEuler20.03 LTS两种底包方案。本文系全网独家在x86平台上基于openeuler-20.03-lts底包构建opengauss数据库V5.0.1LTS的单机容器。

opengauss官网上单机容器部署只有x86-64平台CentOS 7.6和ARM64平台 openEuler20.03 LTS两种方案：

本文探索在 x86-64  openEuler20.03 LTS容器底包上进行数据库容器打包。

一、基础环境

1、宿主机环境

 宿主机为x86平台，操作系统为openEuler 22.03 LTS

# cat /etc/os-release 
NAME="openEuler"
VERSION="22.03 LTS"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 LTS"
ANSI_COLOR="0;31"

2、容器底包

openeuler-20.03-lts：latest

# docker images 
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
openeuler-20.03-lts   latest              eeb84ae20ad2        3 years ago         469MB

3、openGauss版本

如下：x86-64架构、操作系统openeuler-20.03-lts、openGauss——5.0.1企业版安装包

 该文件的SHA256值为：c4687aa6bb02ffc1402b972a01a2515ba8524def624f4c8227c40dcaf38aa9e4

openGauss-5.0.1-openEuler-64bit-all.tar.gz

4、下载安装程序脚本

下载官方安装程序

直接下载链接

二、打包环境准备

1、准备目录和数据库安装包、容器repo源

# mkdir -p dockerfiles/5.0.1
# wget https://opengauss.obs.cn-south-1.myhuaweicloud.com/5.0.1/x86_openEuler/openGauss-5.0.1-openEuler-64bit-all.tar.gz
# sha256sum openGauss-5.0.1-openEuler-64bit-all.tar.gz >sha256_file_amd64
# mv openGauss-5.0.1-openEuler-64bit-all.tar.gz sha256_file_amd64 dockerfiles
# wget https://mirrors.huaweicloud.com/repository/conf/openeuler_x86_64.repo
# mv openeuler_x86_64.repo dockerfiles/5.0.1

2、准备安装脚本

将前面下载的官方安装程序包解压，拷贝文件到相应目录

buildDockerImage.sh------当前目录

dockerfiles目录下应有以下文件：

dockerfile_amd
entrypoint.sh
generatexml.py
gosu-amd64
gs_createtrust.py
install.sh
openGauss-5.0.1-openEuler-64bit-all.tar.gz   (本文件是上一步下载并转移过来的)
sha256_file_amd64                                         (本文件是上一步生成的)
util.sh

完成后的目录结构：

# tree 
.
├── buildDockerImage.sh
└── dockerfiles
    ├── 5.0.1
    │   └── openeuler_x86_64.repo
    ├── dockerfile_amd
    ├── entrypoint.sh
    ├── generatexml.py
    ├── gosu-amd64
    ├── gs_createtrust.py
    ├── install.sh
    ├── openEuler-20.03-LTS.tar.xz
    ├── openGauss-5.0.1-openEuler-64bit-all.tar.gz
    ├── sha256_file_amd64
    └── util.sh

3、修改dockerfiles/dockerfile_amd文件

修改后内容如下:

# vi dockerfiles/dockerfile_amd 
# cat dockerfiles/dockerfile_amd 
FROM openeuler-20.03-lts:latest

ENV OPENGAUSS_VERSION 5.0.1

COPY openGauss-${OPENGAUSS_VERSION}-openEuler-64bit-all.tar.gz .
COPY gosu-amd64 /usr/local/bin/gosu
COPY gs_createtrust.py .
ENV LANG en_US.utf8
COPY 5.0.1/openeuler_x86_64.repo /etc/yum.repos.d/openeuler_x86_64.repo

    /usr/sbin/useradd -u 70 -g omm -d /home/omm omm; \  
    mkdir -p /opengauss && \  
    chmod 700 /opengauss && \  
    mv openGauss-${OPENGAUSS_VERSION}-openEuler-64bit-all.tar.gz /opengauss && \  
    mv gs_createtrust.py /opengauss && \  
    mkdir -p /volume && \  
    chmod -R 755 /volume && \  
    chown -R omm:omm /opengauss

ENV LANG en_US.utf8


ENV GOSU_VERSION 1.12
RUN set -eux; \
     chmod +x /usr/local/bin/gosu


COPY entrypoint.sh /usr/local/bin/
COPY entrypoint.sh /usr/local/bin/
COPY install.sh /usr/local/bin/
COPY util.sh /usr/local/bin/
COPY generatexml.py /usr/local/bin/
RUN chmod 755 /usr/local/bin/entrypoint.sh;ln -s /usr/local/bin/entrypoint.sh /
RUN chmod 755 /usr/local/bin/install.sh;ln -s /usr/local/bin/install.sh /
RUN chmod 755 /usr/local/bin/util.sh;ln -s /usr/local/bin/util.sh /
RUN chmod 755 /usr/local/bin/generatexml.py /

ENTRYPOINT ["entrypoint.sh"]

EXPOSE 5432

4、修改buildDockerImage.sh文件

改后的内容如下：
