callWithRequest putUser

[McKittrick_Kaminski]

Making a custom Kibana plugin, and I'm looking to create a user with the callWithRequest function. I'm able to do some operations like ping and cluster.health, but putUser doesn't seem to be available.

I even took a crawl in the kibana/src/core/server/elasticsearch/api_types.ts, and there doesn't appear to be any security endpoints available.

Is it possible to call putUser using the clients credentials? Push come to shove, I can just create an username, password box and have them enter in admin credentials, and use the nodejs library for ES separately, which I'm doing mostly anyway.

This is correct -- currently the ES client doesn't have definitions for x-pack APIs. At the moment there are two ways to work around this:

1. You can use transport.request to send any arbitrary request to Elasticsearch. This is a catch-all to enable working with any ES APIs which don't have definitions in api_types.ts.
2. You can use core.elasticsearch.createClient to register a custom plugin which extends the ES client and knows how to handle putUser. This is what the x-pack security plugin currently does because it handles some niceties like validation for you. Though I will note that this is all based on the legacy ES client; we have not yet migrated Kibana to using the new JS client, which will offer its own way of extending the client.

Usage of the legacy createClient looks something like this:

setup(core) {
  const client = core.elasticsearch.createClient('foo', {
    plugins: [myClientPlugin],
  });

  const router = core.http.createRouter();
  router.post({
    path: '/my/api',
    validate: {...},
  },
  handler: async (ctx, req, res) => {
    await client.asScoped(request).callAsCurrentUser('putUser', {
      ...params for client plugin
    });
    return response.ok({...});
  });
}
