Trino Docker Image

About the Container

This Docker image is designed to provide the following

  • An out-of-the-box single node cluster with the JMX, memory, TPC-DS, and TPC-H catalogs
  • An image that can be deployed as a full cluster by mounting in configuration
  • An image to be used as the basis for the Kubernetes Trino operator

Quickstart

Run the Trino server

You can launch a single node Trino cluster for testing purposes. The Trino node will function both as a coordinator and a worker. To launch it, execute the following:

docker run -p 8080:8080 --name trino trinodb/trino

Wait for the following message log line:

INFO	main	io.trino.server.Server	======== SERVER STARTED ========

The Trino server is now running on localhost:8080 (the default port).

Run the Trino CLI

Run the Trino CLI, which connects to localhost:8080 by default:

docker exec -it trino trino

You can pass additional arguments to the Trino CLI:

docker exec -it trino trino --catalog tpch --schema sf1

Configuration

Configuration is expected to be mounted /etc/trino. If it is not mounted then the default single node configuration will be used.

Specific Config Options

node.id

The container supplied run-trino command will set the config property node.id to the hostname of the container if it is not specified in the node.properties file. This allows for node.properties to be a static file across all worker nodes if desired. Additionally this has the added benefit of node.id being consistent, predictable, and stable through restarts.

node.data-dir

The default configuration uses /data/trino as the default for node.data-dir. Thus if using the default configuration and a mounted volume is desired for the data directory it should be mounted to /data/trino.

Building a custom Docker image

To build an image for a locally modified version of Trino, run the Maven build as normal for the trino-server and trino-cli modules, then build the image:

./build.sh

The Docker build process will print the ID of the image, which will also be tagged with trino:xxx-SNAPSHOT, where xxx-SNAPSHOT is the version number of the Trino Maven build.

To build an image for a specific released version of Trino, specify the -r option, and the build script will download all the required artifacts:

./build.sh -r 381
