monstache

A Helm chart for deploying Monstache on Kubernetes

How To

Configure MongoDB Source and ElasticSearch Target

At very minimum, specify the MongoDB source and ElasticSearch target under config key.

config:
  change-stream-namespaces:
    - "elasticsearch-master"
  config-database-name: "mongodb"

Configure Mapping

If you need to customize how Monstache do mapping, specify the configuration under mapping key. The expected values is array of object, with all the key and value will be transformed into TOML configuration. To learn more, please check the complete documentation

- namespace: target-namespace
  index: target-index

Configure Middleware

To supply Monstache middleware, specify the code under script key. It expecting an array of object with namespace and script key.

script:
  - namespace: target-namespace
    script:
      lang: js
      code: |
        var counter = 1;
        module.exports = function(doc) {
            doc.foo += "test" + counter;
            counter++;
            return doc;
        }
