cd target_elasticsearch
pipx install .

Configuration

Accepted Config Options

A full list of supported settings and capabilities for this tap is available by running:

target_elasticsearch --about

Source Authentication and Authorization

You can easily run target-elasticsearch by itself or in a pipeline using Meltano.

Executing the Tap Directly

target_elasticsearch --version
target_elasticsearch --help
target_elasticsearch --config CONFIG --discover > ./catalog.json

Developer Resources

Initialize your Development Environment

pipx install poetry
poetry install
poetry run pre-commit install

Create and Run Tests

Create tests within the target_elasticsearch/tests subfolder
To Run tests, first set environment variables in your current shell for all required settings from the Settings section above. Example for UNIX base systems running export Target_elasticsearch_USER_ID="xxxxx" then run:

poetry run pytest

You can also test the target-elasticsearch CLI interface directly using poetry run:

poetry run target_elasticsearch --help

Testing with Meltano

Note: This tap will work in any Singer environment and does not require Meltano. Examples here are for convenience and to streamline end-to-end orchestration scenarios.

Your project comes with a custom meltano.yml project file already created.

Next, install Meltano (if you haven't already) and any needed plugins:

# Install meltano
pipx install meltano
# Initialize meltano within this directory
cd target-elasticsearch
meltano install

# You can spin up elastic locally
make local-es

Now you can test and orchestrate using Meltano:

meltano install
# Test invocation:
meltano invoke target-elasticsearch --version
# test configuration
meltano config target-elasticsearch set --interactive
# OR run a test `elt` pipeline:
meltano elt tap-smoke-test target-elasticsearch

SDK Dev Guide

See the dev guide for more instructions on how to use the SDK to develop your own taps and targets.
