Check-out, compile and run:

$ git clone https://github.com/vespa-engine/sample-apps.git
$ VESPA_SAMPLE_APPS=`pwd`/sample-apps
$ cd $VESPA_SAMPLE_APPS/tensor-playground && mvn clean package
$ docker run --detach --name vespa --hostname vespa-container --privileged \
  --volume $VESPA_SAMPLE_APPS:/vespa-sample-apps --publish 8080:8080 vespaengine/vespa

Wait for the configserver to start:

$ docker exec vespa bash -c 'curl -s --head http://localhost:19071/ApplicationStatus'

Deploy the application:

$ docker exec vespa bash -c '/opt/vespa/bin/vespa-deploy prepare /vespa-sample-apps/tensor-playground/target/application.zip && \
  /opt/vespa/bin/vespa-deploy activate'

Wait for the application to start - then try the examples in the guide:

$ curl -s --head http://localhost:8080/ApplicationStatus

Shutdown and remove the container:
