More aws commands

  • S3 sync with delete + excludes
    aws s3 sync ./ s3://<name>/ --delete --exclude '*.tmp' --exclude '.git/*' --size-only

    Mirror dir to bucket; --delete removes stale keys. note: --size-only skips mtime checks

  • Presigned S3 download URL
    aws s3 presign s3://<name>/path/file.tgz --expires-in 3600

    Generate a time-limited download URL without making the object public

  • Update kubeconfig for EKS
    aws eks update-kubeconfig --name <cluster> --region <id> --alias <cluster> --kubeconfig ~/.kube/config

    Add/refresh an EKS context with a clean alias instead of the long ARN

  • ECR docker login
    aws ecr get-login-password --region <id> | docker login --username AWS --password-stdin <id>.dkr.ecr.<id>.amazonaws.com

    Auth Docker to ECR via stdin so the token never lands in shell history

  • SSM shell without SSH
    aws ssm start-session --target i-<id> --region <id>

    Open an interactive shell on an instance with no open port 22 or bastion
