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

• Pull the openeuler/kyuubi image from docker

  bash
  docker pull openeuler/kyuubi:{Tag}
  

• Run the container in the background

  If container runs successfully, it will store the PID of the server instance into pid/kyuubi--org.apache.kyuubi.server.KyuubiServer.pid. And you are able to get the JDBC connection URL from the log file - logs/kyuubi--org.apache.kyuubi.server.KyuubiServer-.out.

  docker run -d -p ***:*** --name kyuubi openeuler/kyuubi:{Tag}
  

• Enter the container

  Enter the container and view the log file mentioned above.

  docker exec -it kyuubi bash
  

  For example

  Starting and exposing JDBC connection at: jdbc:kyuubi://localhost:***/
  

• Open Connections

  Replace the host and port with the actual ones you’ve got in the step of server startup for the following JDBC URL. The case below open a session for user named apache.

  bash
  bin/kyuubi-beeline -u 'jdbc:kyuubi://localhost:***/' -n apache
  

• Execute Statements

  After successfully connected with the server, you can run sql queries in the kyuubi-beeline console. For instance,

  > SHOW DATABASES;
  

  You will see a wall of operation logs, and a result table in the kyuubi-beeline console.

  bash
  omitted logs
  +------------+
  | namespace  |
  +------------+
  | default    |
  +------------+
  1 row selected (0.2 seconds)
  

• Start Engines

  Engines are launched by the server automatically without end users’ attention. If you use the same user in the above case to create another connection, the engine will be reused. You may notice that the time cost for connection here is much shorter than the last round. If you use a different user to create a new connection, another engine will be started.

  bin/kyuubi-beeline -u 'jdbc:kyuubi://localhost:***/' -n kentyao
  

• Close Connections

  > !quit
  Closing: 0: jdbc:kyuubi://localhost:***/
