Question

Help, deploy error finding executable heroku-php-nginx

I am trying to create a new app using the App Platform which is the built and deployed the same as an existing app in our account, created by a legacy developer.

It is a PHP app, built from a Docker image. On deploy I am getting an error from the Run Command as follows:

starting container: starting non-root container [heroku-php-nginx -C server/digitalocean/nginx_app.conf public/]: error finding executable "heroku-php-nginx" in PATH [/opt/bitnami/php/bin /opt/bitnami/php/sbin /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin]: no such file or directory

My understanding is the Heroku buildpacks are included in the app creation, but perhaps that is not the case if building from a Dockerfile?

However, there is no indication of any Heroku build PHP/Nginx reference in the existing Dockerfile, and the above is the Run command from the legacy app.

So I am a bit stumped here as to what to do. Should the buildpacks be added to Docker since I am going that route to build the app? If so some guidance would be much appreciated.

Hi there,

In theory, if you are deploying using a Dockerfile, the Cloud Native Buildpacks would not be used at all. However, if you don’t provide a dockerfile_path the build system will attempt to use Cloud Native Buildpacks to build your application.

As you already have a Dockerfile, you can follow the steps here on how to use it with the App Platform:

In case that you want to give the Cloud Native build packs a try, then you are most likely seeing the issue as the heroku-php-nginx command is defined in your compsoer.json file. If this is the case, I could suggest following the steps here for more information on how to setup your PHP apps:

Let me know how it goes!

Best,
