Getting started, including Java development

Follow these steps to deploy an application having Java components to the dev zone in the Vespa Cloud. Find more details and tips in the developer guide. Alternative versions of this guide:

• Getting started, without Java components
• Getting started, without Vespa CLI
• Getting started, using pyvespa - for Python developers
• Run Vespa locally, using Docker (with Java).

1. Create a tenant in the Vespa Cloud:

   Create a tenant at console.vespa-cloud.com (unless you already have one).

2. Install the Vespa CLI using Homebrew:

         $ brew install vespa-cli
         

3. Configure the Vespa client:

   $ vespa config set target cloud && \
     vespa config set application tenant-name.myapp
   

   $ export VESPA_CLI_HOME=$PWD/.vespa TMPDIR=$PWD/.tmp
   $ mkdir -p $TMPDIR
   $ vespa config set target cloud
   $ vespa config set application vespa-team.album-rec-java
   

   Use the tenant name from step 2. This guide uses myapp as application name - learn more.

4. Authorize Vespa Cloud access:

   $ vespa auth login
   

   $ export VESPA_CLI_API_KEY="$(echo "$VESPA_TEAM_API_KEY" | openssl base64 -A -a -d)"
   

   Follow the instructions from the command to authenticate.

5. Get a sample application:

   $ vespa clone album-recommendation-java myapp && cd myapp
   

   An application package is the full application configuration. See sample-apps for other sample apps you can clone instead (be sure to pick one that contains Java components).

6. Add public certificate:

   $ vespa auth cert
   

   This creates a self-signed certificate for data plane access (reads and writes), and adds it to the application package. See the security model for details.

7. Build the application:

   $ mvn -U package
   

8. Deploy the application:

   $ vespa deploy --wait 600
   

   The first deployment will take a few minutes while nodes are provisioned. Subsequent deployments on existing nodes will be quicker.

9. Feed documents:

   $ vespa feed src/test/resources/*.json
   

10. Run queries:

    $ vespa query "select * from music where album contains 'head'"
    

    $ vespa query \
        "select * from music where true" \
        "ranking=rank_albums" \
        "ranking.features.query(user_profile)={{cat:pop}:0.8,{cat:rock}:0.2,{cat:jazz}:0.1}"
    

    These requests use the Query API.
