Predefined Dockerfiles

Appliku provides a set of predefined Dockerfiles that you can select from the build image dropdown in your application's Build Settings. These templates cover common stacks and can be used as-is or grabbed and customized to fit your project's needs.

For instructions on using custom Dockerfiles, see Deploy from a Dockerfile.
