Supported tags and respective Dockerfile links

The tag of each presto docker image is consist of the version of presto and the version of basic image. The details are as follows

Usage

In this usage, users can select the corresponding {Tag} based on their requirements.

• Pull the openeuler/presto image from docker

  bash
  docker pull openeuler/presto:{Tag}
  

• Run the container in the background

  You’ll see a series of logs as Presto starts, ending with SERVER STARTED signaling that it is ready to receive queries. We’ll use the Presto CLI to connect to Presto that we put inside the image using a separate Terminal window.

  docker run --name presto openeuler/presto:{Tag}
  

• Access the presto container and start the CLI client

  docker exec -it presto presto
  

• Execute a query against the tpch catalog
