$ cd sample-apps/examples/http-api-using-request-handlers-and-processors && mvn clean package
$ docker run --detach --name vespa --hostname vespa-container \
  --publish 127.0.0.1:8080:8080 --publish 127.0.0.1:19071:19071 \
  vespaengine/vespa

Wait for the configserver to start:

$ curl -s --head http://localhost:19071/ApplicationStatus

$ curl --header Content-Type:application/zip --data-binary @target/application.zip \
  localhost:19071/application/v2/tenant/default/prepareandactivate
