Integrating Docker with AWS ECR: Build, Tag, and Push Images
Step 1: Authenticate Docker to ECR
Get login command:
aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin <account-id>.dkr.ecr.us-west-2.amazonaws.comStep 2: Build and Tag the Image
In my-app dir:
docker build -t my-app .docker tag my-app:latest <account-id>.dkr.ecr.us-west-2.amazonaws.com/my-app-repo:latestStep 3: Push to ECR
docker push <account-id>.dkr.ecr.us-west-2.amazonaws.com/my-app-repo:latestVerify in ECR console.
Troubleshooting: Check IAM permissions (AmazonEC2ContainerRegistryFullAccess).
