Getting started, including Java development

Follow these steps to deploy your first application to the dev zone in the Vespa Cloud. Find more details and tips in the developer guide.

There is also a version of this guide that does not require Maven and Java. The differences from the basic getting started guide are:

• The application package root for applications with components is at src/main/application.
• The components must be built before deploying.

1. Install the Vespa client:

   Using Homebrew:

   $ brew install vespa-cli
   

   Alternatively, download it for Windows, Linux and macOS.

2. Create a tenant in the Vespa Cloud:

   Create a tenant at console.vespa-cloud.com (unless you already have one). This requires a Google or GitHub account, and will start your free trial. Make note of the tenant name, it is used in the next steps.

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 a full list.

6. Add public certificate:

   $ vespa auth cert
   

   This creates a self-signed certificate for application data plane access (reads and writes), and adds it to the application package files. See the security model for more 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 - track progress using the link in the response. 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.

Deploy sample applications - Java

Vespa sample applications is a repository of applications that can be deployed on a local machine or in Vespa Cloud. These are great resources to get more familiar with Vespa. To deploy using Vespa Cloud, run the following steps instead:

1. Get the application (using one of these):

   $ git clone --depth 1 https://github.com/vespa-engine/sample-apps.git && \
     cd sample-apps/the-sample-application
   
   $ vespa clone the-sample-application myapp && \
     cd myapp
   

2. Where the README says vespa deploy, do this instead, using your own tenant name:

   $ vespa config set target cloud && \
     vespa config set application tenant-name.myapp
   $ vespa auth login
   $ vespa auth cert
   $ mvn -U package           # Sample applications with Java code must build before deployment
   $ vespa deploy --wait 600
