In Pipelines, how can I cache gRPC after installing it with pecl? Edited

Hello everyone,

I am just setting up our project's bitbucket-pipelines.yml file. We have a PHP web application that uses the gRPC extension.

My current default build steps are:

image: php:7.3-cli

definitions:
  steps:
    - step: &build
        name: Build
        caches:
          - composer
        script:
          - apt-get update && apt-get install -y ssh unzip autoconf libz-dev git
          - pecl install grpc
          - docker-php-ext-enable grpc
          - curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
          - composer install
    - step: &run_tests
        name: Run Tests
        script:
          - vendor/bin/phpunit --testdox protected/tests

pipelines:
  default:
    - step: *build
    - step: *run_tests

The problem is, pecl install grpc takes over 7 minutes to compile and install.

I was reading the article on Caching dependencies, but I'm not sure how to cache grpc in this case, so I don't have to wait over 7 minutes each time this builds.

Any suggestions on how this is achieved?

Thank you!

Alright, so after spending a good amount of time trying to figure this out, I ended up realizing that I should simply create my own Docker image.

So I made one based on the PHP Docker image "php:7.3-cli" by creating this Dockerfile:

FROM php:7.3-cli

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/

RUN apt-get update && apt-get install -qy ssh unzip autoconf libz-dev git
RUN yes | pecl install grpc-1.26.0
RUN install-php-extensions grpc
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

As you may have noticed, I ended up using a php-extension-installer to help me enable grpc; more details on that here: https://github.com/mlocati/docker-php-extension-installer

After that, while referring to this guide, I uploaded my Docker image to DockerHub and modified my Git repo's "bitbucket-pipelines.yml" file accordingly:

image: asimdlvct/php7.3-grpc1.26.0:ctweb

definitions:
  steps:
    - step: &setup_and_run_tests
        name: Setup dependencies and run tests
        caches:
          - composer
        script:
          - composer install
          - vendor/bin/phpunit --testdox protected/tests

pipelines:
  default:
    - step: *setup_and_run_tests

And now it works great, all running under a minute in Bitbucket Pipelines!

Also, I realized that my previous YAML file was wrong, since each "step" acts as a different build. So I couldn't install the composer dependencies in one step, and run tests that depended on those packages being installed in a different step! Had to be done in the same step, which makes sense in hindsight.
