Trino Community Kubernetes Helm Charts

Fast distributed SQL query engine for big data analytics that helps you explore your data universe

Usage

Helm must be installed to use the charts. Please refer to Helm's documentation to get started.

Once Helm is set up properly, add the repo as follows:

helm repo add trino https://trinodb.github.io/charts/

You can then run helm search repo trino to see the charts.

Then you can install chart using:

helm install my-trino trino/trino --version 0.25.0

Also, you can check the manifests using:

helm template my-trino trino/trino --namespace <YOUR_NAMESPACE>

Documentation

You can find documentation about the chart here.

Development

To test the chart, install it into a Kubernetes cluster. Use kind to create a Kubernetes cluster running in a container, and chart-testing to install the chart and run tests.

brew install helm kind chart-testing
kind create cluster
ct install

To run tests with specific values:

ct install --helm-extra-set-args "--set image.tag=450"

Use the test.sh script to run a suite of tests, with different chart values. If some of the tests fail, use the -s flag to skip cleanup and inspect the resources installed in the Kubernetes cluster. Use -n to use a specific namespace, not a randomly generated one. Use -t to run only selected tests. See the command help (-h) for a list of available tests.

Example:

./test.sh -n trino -s -t default

The documentation is automatically generated from the chart files. Install a git hook to have it automatically updated when committing changes. Make sure you install the pre-commit binary, then run:

pre-commit install
pre-commit install-hooks
