DevOps运维实战-jenkins 实现基本的CI操作

思路：

使用jenkins 拉去gitlab 代码，通过dockerfile 和docker-compose.yml 完成镜像到构建和编排运行。

• 操作jenkins

配置shh 全局变量：

记住一定要密码。

• 在构建里面exec command

• cd /usr/local/docker/jenkins_docker/data/workspace/mytest
  docker-compose down
  docker-compose up -d --build
  docker system prune -f

   这里是使用docker-compose 把应用运行起来。
• Dokcerfile 如下：

FROM mcr.microsoft.com/dotnet/aspnet:5.0-buster-slim AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/sdk:5.0-buster-slim AS build
WORKDIR /src
COPY ["NewNetcore5.csproj","./"]
RUN dotnet restore "./NewNetcore5.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "NewNetcore5.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "NewNetcore5.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "NewNetcore5.dll"]

 Docker-compose 文件

version: '2'
services:
  mytest:
    container_name: mytest
    build:
      context: ./
      dockerfile: Dockerfile
    image: mytest:v2.0.0
    environment:
      - ASPNETCORE_ENVIRONMENT=Development 
    privileged: true
    user: root
    restart: always   
    ports:
      - '5000:80'

ok。 上面已经配置完成。接下来。我们先给gitlab 打一个标签。

然后在jenkins 选择标签生成即可。
