is it possible to run a script before running a pipe?

[yivi]

I'm trying to build a pipeline to build and deploy to S3 one of our angular projects.

I can use the atlassian pipe for this (atlassian/aws-s3-deploy:0.2.4), but since I'm using the same build task for staging and production a specific configuration variable needs to be "injected" on artifact to be uploaded with different values to each environment.

The developer asked a file with the URL for the API backend to be inserted (to use the staging or prod API on build).

I thought of running another script step to generate the file (using a value from a deployment variable) on the distribution directory, but this doesn't seem to work:

image: node:10.15.1

definitions:
  build:
    - step: &build-generate
        script:
          - npm install
          - npm run build:prod
        artifacts:
          - dist/**
  deploy: &deploy-to-s3
    - step:
        name: Deploying
        deployment: staging
        script:
          - echo "var BASE_URL = \"$API_CORE_URL\";" > dist/site-admin/assets/config.js
          - pipe: atlassian/aws-s3-deploy:0.2.4
            variables:
              AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID
              AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY
              AWS_DEFAULT_REGION: "eu-west-1"
              S3_BUCKET: $OUR_AWS_BUCKET_NAME
              LOCAL_PATH: "dist/site-admin"
              ACL: "public-read"
              CACHE_CONTROL: 'max-age=3600'
              DELETE_FLAG: 'true'
              EXTRA_ARGS: '--follow-symlinks'

pipelines:
  tags:
    release-*:
      - step: *build-generate
      - step:
          <<: *deploy-to-s3
          deployment: 'production'
  custom:
    deploy-to-staging:
      - step: *build-generate
      - step:
          <<: *deploy-to-s3

I get an error saying

No commands or pipes defined for the step at [pipelines > custom > deploy-to-staging > 1 > step]. Check that you have defined a valid "script" section.

Apparently this is not valid. How should I do this instead?

Hi @yivi 

You need to move the anchor onto the step i.e.:

  deploy:
    - step: &deploy-to-s3

Hope this helps!

[yivi]

Thanks @davina Davina. Now I get

There is an error in your bitbucket-pipelines.yml at [pipelines > custom > deploy-to-staging > 1 > step]. To be precise: This section should be a map (it is currently defined as a list).

The validator says it's fine, although it's not. Would be nice if the validator ran some of the same checks than the actual thing does.

I don't get any validation errors after that fix.
