Multiple commands in the same build step in Google Cloud Builder

Question

I want to run our automated backend test suite on Google Cloud Builder environment. However, naturally, I bumped into the need to install various dependencies and prerequisites within the Cloud Builder so that our final test runner (php tests/run) can run.

Here's my current cloudbuild.yaml:

steps:

  - name: 'ubuntu'
    args: ['bash', './scripts/install-prerequisites.sh', '&&', 'composer install -n -q --prefer-dist', '&&', 'php init --overwrite=y', '&&', 'php tests/run']

At the moment, the chaining of multiple commands doesn't work. The only thing that's executed is the bash ./scripts/install-prerequisites.sh part. How do I get all of these commands get executed in order?

Answer 1

You have 2 options to achieve this at the moment I believe:

1. create a script that has the sequence of commands you'd like and call the script directly:

# cloudbuild.yaml
steps:
  - name: 'ubuntu'
    args: ['./my-awesome-script.sh']

# my-awesome-script.sh
/usr/bin/env/bash

set -eo pipefail

./scripts/install-prerequisites.sh
composer install -n -q --prefer-dist
php init --overwrite=y
php tests/run

2. Call bash -c with all the commands you'd like to follow:

steps:
  - name: 'ubuntu'
    args: ['bash', '-c', './scripts/install-prerequisites.sh && composer install -n -q --prefer-dist && php init --overwrite=y && php tests/run']
