Serverless Glue

Update Version 2.X.X

I set out to revive this project by refactoring the code, to keep it clean and easy to understand.

The principal changes here

This is a plugin for Serverless framework that provide the posibliti to deploy AWS Glue Jobs and Triggers

Install

1. run npm install --save-dev serverless-glue
2. add serverless-glue in serverless.yml plugin section

   plugins:
       - serverless-glue

How it works

The plugin creates CloufFormation resources of your configuration before make the serverless deploy then add it to the serverless template.

So any glue-job deployed with this plugin is part of your stack too.

How to configure your GlueJob(s)

Configure yours glue jobs in the root of servelress.yml like this:

Glue:
  bucketDeploy: someBucket # Required
  s3Prefix: some/s3/key/location/ # optional, default = 'glueJobs/'
  tempDirBucket: someBucket # optional, default = '{serverless.serviceName}-{provider.stage}-gluejobstemp'
  tempDirS3Prefix: some/s3/key/location/ # optional, default = ''. The job name will be appended to the prefix name
  jobs:
    - name: super-glue-job # Required
      scriptPath: src/script.py # Required script will be named with the name after '/' and uploaded to s3Prefix location
      tempDir: true # Optional true | false

you can define a lot of jobs..

  Glue:
    bucketDeploy: someBucket
    jobs:
      - name: jobA
        scriptPath: scriptA
        ...
      - name: jobB
        scriptPath: scriptB
        ...

And a lot of triggers..

  Glue:
    triggers:
        - name:
            ...
        - name:
            ...
