Azure devops notes

Planning

• by Product Manager
• What to developed
• Why: business value

Agile is usually used in a workflow.

Azure boards is the module we use on the platform.

• create work items
• track progress
• discussion

Code

Azure Repos

• host code
• similar to Github
• create branch -> pull request by others

Azure Pipelines build

What we want to do is to release the new feature.
Process: code -> test -> package -> deploy

CI

• continuous intergration
• test -> package

pipeline

• write in yaml
• test -> package -> build image -> push to repo
• use task (pre-created script)
• Job: boundary of a set of steps
  • run in defferent environments
  • each runs on an agent
  • which OS / version
• agent
  • selected from pools

Build or CI pipeline

• test code changes
• produce an artifact for deployment

Azure Artifacts

use Docker

Docker images
stored in Container Registry

Azure Pipelines Stages

CD: continuous delivery

CI/CD

• fully automated process
• code changes to production environment

Stage

• logical boundery in the pipeline
• contains jobs
• run after one

deploy

• intermediate environment: dev, testing, prod
• avoid pipeline configuration code
  • extract common configuration to a template

Azure Pipelines Environments

• link tickets in Azure Boards

Release Pipelines

separate pipeline for CD
1 CI/CD pipeline in yaml

Test Plans

• test cases
  • steps / output
• automated tests
• test reports

Azure Architecture

SaaS / Azure DevOps Services + Configure own agents
Pipeline task run on separate machines: Agent

Service Connections

interact with other platforms

• push docker image to container repository
• deploy to remote service: aws, gcp
• external code repository
  manage external connection: authenticate

Comparison

Azure Devops: devops; everything in 1 platform

• better traceability: linked data

Jenkins / argo: CI/CD processes only
Gitlab

• similar

aws

• more than devops
• cloud platform
• microsoft azure + azure devops
