DISCLAIMER: No alterations are necessary to standard applications in order to be built by buildpacks.
Some applications here have optional files for extended functionality. They will be called out in their README.md file.
To build images for most of these apps, simply execute:
pack build -p apps/<APP> --builder cnbs/sample-builder:<jammy OR alpine> sample-app
After building the app you should be able to simply run it via docker run -it -p 8080:8080 sample-app
.
Go to localhost:8080 to see the app running.
It might be interesting to see how apps get turned into layers, eh? Check out buildpacks to take the next step.
