DevOps Classroom Notes – 23/July/2024

Docker CI Pipeline

• Project: nopCommerce

• code Refer Here

• pre-reqs

  • docker

  curl -fsSL https://get.docker.com -o install-docker.sh
  sh install-docker.sh
  sudo usermod -aG docker <username>
  exit
  # relogin
  

• Get the code locally

git clone https://github.com/nopSolutions/nopCommerce.git

• Now build the code

cd nopCommerce
docker image build -t nopcommerce:latest .

• After this execute the command

docker image ls

• Lets make this work in our azure devops, import repository
• Lets consider CI as a stage
• Create a pipeline

---
stages:
  - stage: ci
    displayName: building code
    jobs:
      - job: docker
        displayName: Build Image on Docker
        pool:
          vmImage: ubuntu-22.04
        steps:
          - task: Docker@2
            inputs:
              command: build
              buildContext: '**'
              Dockerfile: '**/Dockerfile'
    

• Exercise: Write a pipeline as collection of jobs with exactly same steps.

---
jobs:
  - job: docker
    displayName: Build using Docker
    pool:
      vmImage: ubuntu-22.04
    steps:
      - task: Docker@2
        inputs:
          command: build
          buildContext: '**'
          Dockerfile: '**/Dockerfile'

• Lets build a Project Refer Here
  • Jobs:
    • Dotnet build
      • dotnet build eShopOnWeb.sln
    • Docker build
      • docker compose build
• Dotnet build Tasks: Refer Here

- task: DotNetCoreCLI@2
  inputs:
    command: 'build'
    projects: eShopOnWeb.sln

• Docker compose build Refer Here

- task: DockerCompose@0
  inputs:
    containerregistrytype: 'Azure Container Registry'
    dockerComposeFile: '**/docker-compose.yml'
    action: Build services

• Pipeline

---
jobs:
  - job: dotnetbuild
    displayName: Build using Dotnet
    pool:
      vmImage: ubuntu-22.04
    steps:
      - task: DotNetCoreCLI@2
        inputs:
          command: 'build'
          projects: eShopOnWeb.sln
  - job: dockercompose
    displayName: Build using Docker Compose
    pool:
      vmImage: ubuntu-22.04
    steps:
      - task: DockerCompose@0
        inputs:
          containerregistrytype: 'Azure Container Registry'
          dockerComposeFile: '**/docker-compose.yml'
          action: Build services

• Lets express the same as two different stages

---
stages:
  - stage: dotnet
    jobs:
      - job: dotnetbuild
        displayName: Build using Dotnet
        pool:
          vmImage: ubuntu-22.04
        steps:
        - task: DotNetCoreCLI@2
          inputs:
            command: 'build'
            projects: eShopOnWeb.sln
  - stage: docker
    dependsOn: dotnet
    jobs:
      - job: dockercompose
        displayName: Build using Docker Compose
        pool:
          vmImage: ubuntu-22.04
        steps:
        - task: DockerCompose@0
          inputs:
            containerregistrytype: 'Azure Container Registry'
            dockerComposeFile: '**/docker-compose.yml'
            action: Build services
