Trino Community Kubernetes Helm Charts

A repository of Helm charts for the Trino community. The following charts are included:

• trino/trino for Trino
• trino/trino-gateway for Trino Gateway

Usage

Helm must be installed to use the charts. 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/

Run helm search repo trino to see the latest charts with the string trino in the name to get an output similar to the following:

NAME               	CHART VERSION	APP VERSION	DESCRIPTION
trino/trino        	0.34.0       	465        	Fast distributed SQL query engine for big data ...
trino/trino-gateway	1.13.0       	13         	A Helm chart for Trino Gateway

Use helm search repo trino -l for information about all available versions.

After configuring your Kubernetes cluster, you can install Trino with the chart trino/trino using:

helm install my-trino trino/trino --version 0.34.0

Also, you can check the manifests using:

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

Similarly install Trino Gateway with the trino/trino-gateway chart.

Documentation

More information about Trino, Trino Gateway, and the charts is available in the following resources:

• Trino Kubernetes documentation
• trino/trino chart configuration
• Trino documentation
• Trino Gateway Kubernetes documentation
• trino/trino-gatewa chart configuration
• Trino Gateway documentation

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=465"

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
