Tips for building integrationsedit

The section offers a set of tips for developers to improve integrations that they’re working on. It combines hints, guidelines, recommendations and tricks. Please consider this section as a live document that may evolve in the future, depending on the business or technical requirements for the entire platform (Elastic Package Registry, Elastic Agent and Kibana).

elastic-packageedit

elastic-package is a command line tool, written in Go, used for developing Elastic packages. It can help you lint, format, test and build your packages. This is the official builder tool to develop Integrations. See the Getting started section to ramp up quickly and review its features.

If you need the revision of elastic-package in the correct version (the same one as the CI uses), which is defined in go.mod, use the following command (in the Integrations repository):

$ go build github.com/elastic/elastic-package
$ ./elastic-package help

New integrationsedit

Manifest filesedit

  1. Set the initial version to 0.1.0.

    Tagging the integration with a lower version, like 0.0.1, means that it’s at very early stage and most likely it doesn’t work at all. It might be partially developed.

  2. Select one or two categories for the integration.

    The list of available categories is present in the Package Registry source: https://github.com/elastic/package-registry/blob/1dd3e7c4956f7e34809bb87acae50b2a63cd7ad0/packages/package.go#L29-L55

  3. Make sure that the version condition for Kibana is set to +^7.10.0+ and not >=7.10.0. Otherwise the package is also in 8.0.0 but we do not know today if it will actually be compatible with >= 8.0.0.

    conditions:
  kibana.version: '^7.10.0'

  4. Set the proper package owner (either Github team or personal account)

    Good candidates for a team: elastic/integrations, elastic/security-service-integrations

    Update the .github/CODEOWNERS file accordingly.

All integrationsedit

Developmentedit

  1. When you’re developing integrations and you’d like to propagate your changes to the package registry, first rebuild the package:

    $ cd packages/apache
$ elastic-package build

    Then, rebuild and redeploy the Package Registry:

    It’s important to execute the following command in the Integrations repository.

    $ elastic-package stack up -v -d --services package-registry

    Explanation: it’s much faster to rebuild and restart the container with the Package Registry, than work with mounted volumes.

Code reviewersedit

  1. Ping "Team:Integrations".

    Use the team label to notify relevant team members about the incoming pull request.

Manifest filesedit

  1. Descriptions of configuration options should be as short as possible.

    Remember to keep only the meaningful information about the configuration option.

    Good candidates: references to the product configuration, accepted string values, explanation.

    Bad candidates: Collect metrics from A, B, C, D,…​ X, Y, Z datasets.

  2. Descriptions should be human readable.

    Try to rephrase sentences like: Collect foo_Bar3 metrics, into Collect Foo Bar metrics.

  3. Description should be easy to understand.

    Simplify sentences, don’t provide information about the input if not required.

    Bad candidate: Collect application logs (log input)

    Good candidates: Collect application logs, Collect standard logs for the application

  4. Letter casing is important for screenshot descriptions.

    These descriptions are visualized in the Kibana UI. It would be better experience to have them clean and consistent.

    Bad candidate: filebeat running on ec2 machine

    Good candidates: Filebeat running on AWS EC2 machine

  5. If package relies on some feature or a field, available only in a specific stack or beats version, kibana.version condition should be adjusted accordingly in the package’s manifest.yml:

    conditions:
   kibana.version: '^8.7.0'

    The package version with such condition as above will be only available in Kibana version >=8.7.0

    Changing dashboards and visualizations using an unreleased version of Kibana might be unsafe since the Kibana Team might make changes to the Kibana code and potentially the data models. There is no guarantee that your changes won’t be broken by the time new Kibana version is released.

CIedit

  1. Run elastic-package check and elastic-package test locally.

    If you want to verify if your integration works as intended, you can execute the same steps as CI:

    $ cd packages/apache
$ elastic-package check -v
$ elastic-package test -v

    Keep in mind that the elastic-package test command requires a live cluster running and exported environment variables. The environment variables can be set with eval "$(elastic-package stack shellinit)".

Fieldsedit

  1. Remove empty fields files.

    If you notice that fields file (e.g. package-fields.yml) doesn’t contain any field definitions or it defines root only, feel free to remove it.

    Bad candidate:

    - name: mypackage.mydataset
  type: group
