Heroku Cedar Stack images
This repository holds recipes for building the modified Heroku Cedar stack images. This image have libicu-dev installed. The recipes are also rendered into Docker images that are available on Docker Hub. Lists of packages installed on the current Cedar stacks are published on Heroku Dev Center.
This image can be used as replacement for the original cedar image in your Dockerfile. Replace
FROM heroku/cedar:14 with
FROM donnykurnia/heroku-cedar-libicu:14 and now you are using base image with libicu-dev already installed.
