Using Heroku cedar 14 stack as a Docker image

Recently I had my application running on cedar-14 stack in Heroku But since End-of-life window has begun and builds won't be available, I decided to use Docker, so Heroku will host Docker container with my application on cedar-14 stack as base Docker image.

So far this is my Dockerfile

FROM heroku/cedar

WORKDIR /app

COPY index.js .
COPY package.json .

But when I was using plain cedar-14 on Heroku, I also had .buildpacks, Aptfile and Procfile and these files were interpreted by Heroku environment. How can I make them work in a Docker environment now?

.buildpacks, Aptfile is replaced by Dockerfile. You need to adjust your Dockerfile. Procfile is replaced by heroku.yml (see here.)

You can use cedar as your base image but I advise you to use latest LTS image and start from there.
