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 469MB3、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/5.0.12、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:latestENV OPENGAUSS_VERSION 5.0.1COPY openGauss-${OPENGAUSS_VERSION}-openEuler-64bit-all.tar.gz .

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/util.sh;ln -s /usr/local/bin/util.sh /
RUN chmod 755 /usr/local/bin/generatexml.py /ENTRYPOINT ["entrypoint.sh"]EXPOSE 54324、修改buildDockerImage.sh文件
改后的内容如下：
