Bitbucket Pipes PHP - Google App Engine Standard deploy - composer install not running

[tomerrett]

Is there a way to run `composer install` as a part of the bitbucket pipes pipeline for Google App Engine Standard? Currently my PHP code is being deployed without running composer install so no dependancies are deployed. Is there a way around this or can I not use Bitbucket Pipes for this? I have tried running composer in another step in the pipeline - however the code that the pipe deploys is not from the previous step as below:

bitbucket-pipelines.yml

image: php:7.2.9
pipelines: 
branches: uat: 
- step: 
script: 
- apt-get update && apt-get install -y unzip 
- curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer 
- composer require monolog/monolog 
- composer install 
- step: name: Deploy to UAT deployment: uat 
script: 
- pipe: atlassian/google-app-engine-deploy:0.3.1 variables: KEY_FILE: $KEY_FILE PROJECT: '**project**' DEPLOYABLES: 'app.yaml' PROMOTE: 'true' STOP_PREVIOUS_VERSION: 'true'

Hi @tomerrett . It looks like you don't really need to run composer install yourself as gcloud should do this for you. This page shows how to configure you application so all dependencies are automatically installed each time you deploy a new version of the app.  Let us know if this doesn't work for you.

Thanks, yes you are correct, seems like there is an issue in google app engine, where the 'post-autoload-dump' triggered script in composer.json that runs @Php artisan package:discover does not run (or does not have write access to the filesystem) hence deploy fails.

but in general @Alexander Zhukov is there a way to build code in other steps and then pass it to a pipe? or is this not supported?

Yes, that's totally possible with pipelines artifacts.
