Package Exports

serverless-glue
serverless-glue/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (serverless-glue) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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

Install

run npm install --save-dev serverless-glue
add serverless-glue in serverless.yml plugin section
```
plugins:
    - serverless-glue
```

How work

The plugin create 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 configure your GlueJobs

Configure yours glue jobs in custom section 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
      type: spark # spark / pythonshell # Required
      glueVersion: python3-2.0 # Required python3-1.0 | python3-2.0 | python2-1.0 | python2-0.9 | scala2-1.0 | scala2-0.9 | scala2-2.0
      role: arn:aws:iam::000000000:role/someRole # Required

          args: # Optional
            arg1: value1
            arg2: value2
          timeout: 30 # Optional

you can define a lot of jobs..

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

And a lot of triggers..

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