Struggling to Implement Azure DevOps CI/CD with Node.js and Docker for a React App
I've been banging my head against this for hours... Quick question that's been bugging me - I've been struggling with this for a few days now and could really use some help. While setting up a CI/CD pipeline for my React application using Azure DevOps, I’m hitting a roadblock with Docker configurations. The project relies heavily on Docker containers, and I want to ensure that both the build and deployment processes are seamless. After following some online tutorials, I ended up with a basic pipeline configuration in my `azure-pipelines.yml` file, which looks something like this: ```yaml trigger: branches: include: - main pool: vmImage: 'ubuntu-latest' steps: - script: | echo Building the React app... npm install npm run build displayName: 'Build the React app' - task: Docker@2 inputs: command: 'build' repository: 'myusername/myapp' Dockerfile: '**/Dockerfile' tags: 'latest' displayName: 'Build Docker image' ``` However, this setup does not seem to push the image to my Azure Container Registry. I tried adding a task to log in to the registry using the `Docker@2` task, but the login commands return errors about authentication failures. Here’s what I attempted: ```yaml - task: Docker@2 inputs: command: 'login' containerRegistry: 'myRegistryConnection' ``` I’ve verified the service connection, and it appears to be configured correctly. Still, I get the following error in the logs: `Error: failed to authorize: failed to fetch anonymous token: Get "https://myregistry.azurecr.io/oauth2/token": unauthorized: HTTP 401` Additionally, I’ve searched for community solutions that suggest ensuring the service principal has the right permissions, but I’m still stuck. Is there a specific configuration I might be missing related to the Docker task in Azure DevOps or the way I’ve set up the service connection? Any insights on best practices for Docker and Azure DevOps would be appreciated. This is part of a larger service I'm building. What am I doing wrong? My development environment is macOS. This is part of a larger web app I'm building. Any ideas how to fix this? The project is a CLI tool built with Yaml.
