<p>Istio RBAC (Role Based Access Control) defines ServiceRole and ServiceRoleBinding
objects.</p>
<p>A ServiceRole specification includes a list of rules (permissions). Each rule has
the following standard fields:
* services: a list of services.
* methods: HTTP methods. In the case of gRPC, this field is ignored because the value is always &ldquo;POST&rdquo;.
* paths: HTTP paths or gRPC methods. Note that gRPC methods should be
presented in the form of &ldquo;packageName.serviceName/methodName&rdquo;.</p>
<p>In addition to the standard fields, operators can use custom fields in the &ldquo;constraints&rdquo;
section. The name of a custom field must match one of the &ldquo;properties&rdquo; in the &ldquo;action&rdquo; part
of the &ldquo;authorization&rdquo; template (https://github.com/istio/istio/blob/master/mixer/template/authorization/template.proto).</p>
<p>For example, suppose we define an instance of the &ldquo;authorization&rdquo; template, named &ldquo;requestcontext&rdquo;.</p>
<pre><code class="language-yaml">apiVersion: &quot;config.istio.io/v1alpha1&quot;
kind: authorization
metadata:
name: requestcontext
namespace: istio-system
spec:
subject:
user: source.user | &quot;&quot;
groups: &quot;&quot;
properties:
service: source.service | &quot;&quot;
namespace: source.namespace | &quot;&quot;
action:
namespace: destination.namespace | &quot;&quot;
service: destination.service | &quot;&quot;
method: request.method | &quot;&quot;
path: request.path | &quot;&quot;
properties:
version: request.headers[&quot;version&quot;] | &quot;&quot;
</code></pre>
<p>Below is an example of ServiceRole object &ldquo;product-viewer&rdquo;, which has &ldquo;read&rdquo; (&ldquo;GET&rdquo; and &ldquo;HEAD&rdquo;)
access to &ldquo;products.svc.cluster.local&rdquo; service at versions &ldquo;v1&rdquo; and &ldquo;v2&rdquo;. &ldquo;path&rdquo; is not specified,
so it applies to any path in the service.</p>
<pre><code class="language-yaml">apiVersion: &quot;config.istio.io/v1alpha1&quot;
kind: ServiceRole
metadata:
name: products-viewer
namespace: default
spec:
rules:
- services: [&quot;products.svc.cluster.local&quot;]
methods: [&quot;GET&quot;, &quot;HEAD&quot;]
constraints:
- key: &quot;version&quot;
value: [&quot;v1&quot;, &quot;v2&quot;]
</code></pre>
<p>A ServiceRoleBinding specification includes two parts:
* &ldquo;roleRef&rdquo; refers to a ServiceRole object in the same namespace.
* A list of &ldquo;subjects&rdquo; that are assigned the roles.</p>
<p>A subject is represented with a set of &ldquo;properties&rdquo;. The name of a property must match one of
the fields (&ldquo;user&rdquo; or &ldquo;groups&rdquo; or one of the &ldquo;properties&rdquo;) in the &ldquo;subject&rdquo; part of the &ldquo;authorization&rdquo;
template (https://github.com/istio/istio/blob/master/mixer/template/authorization/template.proto).</p>
<p>Below is an example of ServiceRoleBinding object &ldquo;test-binding-products&rdquo;, which binds two subjects
to ServiceRole &ldquo;product-viewer&rdquo;:
* User &ldquo;alice@yahoo.com&rdquo;
* &ldquo;reviews&rdquo; service in &ldquo;abc&rdquo; namespace.</p>
<pre><code class="language-yaml">apiVersion: &quot;config.istio.io/v1alpha1&quot;
kind: ServiceRoleBinding
metadata:
name: test-binding-products
namespace: default
spec:
subjects:
- user: alice@yahoo.com
