<h2 id="namespace-level-access-control">Namespace-level access control</h2>
|
|
<p>Using Istio RBAC, you can easily setup namespace-level access control by specifying all (or a collection of) services
|
|
in a namespace are accessible by services from another namespace.</p>
|
|
<p>In our Bookinfo sample, the “productpage”, “reviews”, “details”, “ratings” services are deployed in “default” namespace.
|
|
The Istio components like “ingress” service are deployed in “istio-system” namespace. We can define a policy that
|
|
any service in “default” namespace that has “app” label set to one of the values in [“productpage”, “details”, “reviews”, “ratings”]
|
|
is accessible by services in the same namespace (i.e., “default” namespace) and services in “istio-system” namespace.</p>
|
|
<p>Run the following command to create a namespace-level access control policy.</p>
|
|
<pre><code class="language-command" data-lang="command">$ istioctl create -f @samples/bookinfo/kube/istio-rbac-namespace.yaml@
|
|
</code></pre><p>The policy does the following:</p>
|
|
<ul>
|
|
<li>
|
|
<p>Creates a <code>ServiceRole</code> “service-viewer” which allows read access to any service in “default” namespace that has “app” label
|
|
set to one of the values in [“productpage”, “details”, “reviews”, “ratings”]. Note that there is a “constraint” specifying that
|
|
the services must have one of the listed “app” labels.</p>
