Now turn the Dockerfile into a real image and run it. Run these commands one after the other:

Write the Dockerfile again: FROM alpine and CMD ["echo", "Welcome to the greeting app"]
Build it tagged greetapp
Run greetapp so its CMD greeting prints

Try it yourself

Terminal

cat > Dockerfile << 'EOF'
FROM alpine
CMD ["echo", "Welcome to the greeting app"]
