微软Azure DevOps自动化部署

1.准备一个https://hub.docker.com账号，申请一个免费的镜像仓库(免费账户可以申请一个)

创建docker远程镜像库

2.新建一个mvc的项目

给这个项目加上Dockerfile文件（AzureDemo/AzureDemo/..中添加）

FROM dukecheng/aspnetcore:aspnetcore-runtime-2.2.0
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "AzureDemo.dll"]

在sln同级添加三个文件
azure_build.sh

workspace=`pwd`
docker run --rm -v ~/.cache:/root/.cache -v ~/.config:/root/.config -v ~/.gnupg:/root/.gnupg -v ~/.local:/root/.local -v ~/.npm:/root/.npm -v `pwd`/SanBlog:/data digitallyseamless/nodejs-bower-grunt bash -c "bower install && npm install"
docker run --rm -v ~/.dotnet:/root/.dotnet -v ~/.nuget:/root/.nuget -v ${workspace}:/src --workdir /src dukecheng/aspnetcore:aspnetcore-sdk-2.2.100-preview3-009430 bash -c "dotnet restore ./AzureDemo.sln && rm -rf ./AzureDemo/AzureDemo/obj/Docker/publish && dotnet publish ./AzureDemo/AzureDemo.csproj -c Release -o ./obj/Docker/publish"

azuredemo.base.yml

# Docker image
# Build a Docker image to deploy, run, or push to a container registry.
# Add steps that use Docker Compose, tag images, push to a registry, run an image, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/docker

pool:
vmImage: 'Ubuntu 16.04'

variables:
imageName: 'your-container-image-name:$(build.buildId)'

steps:
- script: docker build -f Dockerfile -t $(imageName) .
displayName: 'docker build'

azuredemo.base.yml
version: '3'

services:
azuredemoweb:
image: shitong/shitong:${IM_TAG-latest}
networks:
- appnet
volumes:
- /var/log:/var/log
- /data/azure:/app/data
redis:
image: redis
networks:
- appnet
ports:
- 7379:6379
volumes:
- /data/redis:/data
- /var/log:/var/log
mongo:

volumes:

这块的azuredemoweb节点下的image:shitong/shitong:${IM_TAG-latest}

shitong/shitong就是我们第一步所建的hub.docker.com上的镜像文件库

azuredemo.Development.yml

version: '3'

services:
azuredemoweb:
environment:
- ASPNETCORE_ENVIRONMENT=Development
ports:
- 8080:80

项目结构

3.准备Azure DevOps帐号用来托管代码，使用pipeline自动打包docker镜像

把我们第二步准备的项目push到Azure DevOps

该准备的都准备好了
接下来就是重点了

之后就会变成这样

下面会有四个步骤:

(1).还原nuget等依赖包发布项目

(2).打包成docker镜像

(3).推送docker镜像到docker hub

(4).服务器pull docker镜像远程部署运行项目

cd /data/deploy/ && export IM_TAG=azuredemo_$(Build.BuildId)  && docker pull shitong/shitong:${IM_TAG} && docker-compose -f azuredemo.base.yml -f azuredemo.Development.yml config > docker-stack.yml && docker stack deploy --with-registry-auth -c docker-stack.yml myapp
