2.Build the Production Image:Target Dockerfile.prod explicitly.Build your image using your production Dockerfile (Dockerfile.prod). Give it a primary tag corresponding to your exact semantic version:

bash
docker build -f Dockerfile.prod -t acmecorp/myapp:2.4.1 .

3.Apply Additional Version Tags

bash
# Major & Minor versions (auto-updated on patch releases)
docker tag acmecorp/myapp:2.4.1 acmecorp/myapp:2.4
docker tag acmecorp/myapp:2.4.1 acmecorp/myapp:2

# Git Commit SHA for exact build traceability
docker tag acmecorp/myapp:2.4.1 acmecorp/myapp:sha-a1b2c3d

# Floating latest tag for production-ready status
docker tag acmecorp/myapp:2.4.1 acmecorp/myapp:latest
bash
docker build -f Dockerfile.prod -t acmecorp/myapp:2.4.1 .
docker tag acmecorp/myapp:2.4.1 acmecorp/myapp:latest

4.Push All Tags to Docker Hub:

Push all created tags to your remote registry in one command:
