Presto 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 Presto operator

Quickstart

Run the Presto server

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

docker run -p 8080:8080 --name presto prestosql/presto

Wait for the following message log line:

INFO	main	io.prestosql.server.PrestoServer	======== SERVER STARTED ========

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

Run the Presto CLI

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

docker exec -it presto presto

You can pass additional arguments to the Presto CLI:

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

Configuration

Configuration is expected to be mounted to either to /etc/presto or /usr/lib/presto/etc (the latter takes precedence). If neither of these exists then the default single node configuration will be used.

Specific Config Options

node.id

The container supplied run-presto 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/presto 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/presto.

Building a custom Docker image

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

./build-local.sh

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