Procedure

  1. Expose the Data Grid service for external access.

  2. Create local variables for the public route and credentials.

    1. Export the host for the public route to a local variable. 

      $ export DATAGRID_HOST=$(oc get route example-rhdg -o jsonpath="{.spec.host}")

    2. Export the generated password from the secret to a local variable. 

      $ export PASS=$(oc get secret example-rhdg-app-generated-secret -o jsonpath="{.data.password}" | base64 --decode)

  3. Store some data through the HTTP endpoint. 

    $ curl -v \
    -X POST \
    -u developer:${PASS} \
    -H 'Content-type: text/plain' \
    -d 'test-value' \
    ${DATAGRID_HOST}/rest/default/test-key
...
< HTTP/1.1 200 OK
