分享一个dotnet自动发布的脚本

Docker 2022-09-02

前置

准备一台CentOS7

  安装 git、docker、docker-register本地仓库、dotnet

项目中添加Dockerfile、docker-stack.yml

 

脚本原理：

通过git拉取分支最新提交，执行dotnet publish 编译项目，

运行docker build 和docker push推到本地仓库中

运行docker stack deploy 发布 到Swarm集群

 

扩容缩容都是Swarm集群提供

可通过给Swarm集群中的机器打标签，通过docker-stack.yml 只发布到指定标签的机器

 

只是最近研究的demo代码，不应做为生产使用，出现问题，概不负责

 

#!/bin/bash
# ==========================================
# ！！！项目根目录下必须包含 Dockerfile 和 docker-stack.yml 文件！！！
# 
# ==========================================

#@echo off

echo work-dir: 
pwd
# ==========================================
# 项目Git地址 eg http://1.git
projectGitPath=http://1.git
# 分支名 eg master
branchName=master

# 项目名
projectName=my_maintain
# dotnet发布项目 eg ~/projects/app1/app1.csproj
dotnetProjectPath=./Project/MyMaintain/MyMaintain.csproj
# dotnet机器RID eg linux-x64
dotnetRID=linux-x64
# dotnetSelfContained eg false
dotnetSelfContained=false
# dotnet发布目录 eg d:/dotnetpublish/app1
dotnetPublishOutput=/data/dotnetpublish/${projectName}/${branchName}

# docker本地仓库地址 192.168.1.1:5000
dockerRegister=192.168.97.168:5000

# dockerStack配置 eg xxx.yml
dockerStackcfgName=docker-stack.yml
# dockerStack名 eg xxx_stack
dockerStackName=${projectName}_stack
# ==========================================

git status

# 切换当前分支
echo process GitBranch: ${branchName}
git checkout ${branchName}
if [ $? != 0 ]
then
 exit 1

# 拉取当前分支

# 创建发布目录
if [ ! -d ${dotnetPublishOutput} ]
then
  echo mkdir -p ${dotnetPublishOutput}
  mkdir -p ${dotnetPublishOutput}

# 执行打包dotnet命令

# 切换到发布目录

cd ${dotnetPublishOutput}
echo work-dir:

# 执行docker build

执行过程如下：

[root@Box168 XXXLib]# /bin/sh ../auto-deployLF.sh
work-dir:
/home/gitRespo/XXXLib
位于分支 master
您的分支与上游分支 'origin/master' 一致。

无文件要提交，干净的工作区
process GitBranch: master
已经位于 'master'
您的分支与上游分支 'origin/master' 一致。
