|
|
<p>A <em>Leaf Node</em> allows an extension to a cluter or supercluster that bridges accounts and security domains. This is useful in IoT and edge scenarios and when the local server traffic should be low RTT and local unless routed to the super cluster.</p>
|
|
<p>Leaf Nodes leverage <a href="../nats_server/jwt_auth.html">accounts</a> and JWTs to enable a server to connect to another and filter messages as per the leaf node's account user configuration.</p>
|
|
<p>This effectively means that the leaf node clusters with the other server at an account level:</p>
|
|
<ul>
|
|
<li>Leaf nodes clients authenticate locally (or just connect if authentication is not required)</li>
|
|
<li>Traffic between the leaf node and the cluster assumes the restrictions of the user configuration used to create the leaf connection. <ul>
|
|
<li>Subjects that the user is allowed to publish are exported to the cluster. </li>
|
|

<p>Leaf Nodes are an important component as a way to bridge traffic between local NATS servers you control and servers that are managed by a third-party. Synadia's <a href="https://www.synadia.com/" target="_blank">NATS Global Service (NGS)</a> allows accounts to use leaf nodes, but gain accessibility to the global network to inexpensively connect geographically distributed servers or small clusters.</p>

|
|
<p>Let's create an second user called 'nolimit'</p>
|
|
<pre class="language-"><code class="lang-text">> nsc add user -n nolimit
|
|
Generated user key - private key stored "~/.nkeys/O/accounts/A/users/nolimit.nk"
|
|
Generated user creds file "~/.nkeys/O/accounts/A/users/nolimit.creds"
|

Success! - added user "nolimit" to "A"
|
|
</code></pre>
|
|
<p>Start a nats-account-server:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-account-server -nsc ~/.nsc/nats/O
|
|
</code></pre>
|
|
<p>Create the server configuration file (server.conf) with the following contents:</p>
|
|
<pre class="language-"><code class="lang-text">operator: /Users/synadia/.nsc/nats/O/O.jwt
|
|
resolver: URL(http://localhost:9090/jwt/v1/accounts/)
|
|
leafnodes {
|
|
listen: "127.0.0.1:4000"
|
|
}
|
|
</code></pre>
|
|
<p>The server configuration naturally requires an <code>operator</code> and <code>resolver</code> to deal with the JWT authentication and accounts. In addition the <code>leafnodes</code> configuration exposes a <code>listen</code> where the server will receive leaf nodes. In this case on the localhost on port 4000.</p>
|
|
<p>Start the nats-server:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-server -c server.conf
|
|
</code></pre>
|
|
<p>Create a subscriber on the server:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-sub -creds ~/.nkeys/O/accounts/A/users/nolimit.creds ">"
|
|
Listening on [>]
|
|
</code></pre>
|
|
<p>Create the leaf server configuration (leaf.conf) with the following contents:</p>
|
|
<pre class="language-"><code class="lang-text">port: 4111
|
|
leafnodes {
|
|
remotes = [
|
|
{ url: nats-leaf://localhost:4000,
|
|
credentials: /Users/synadia/.nkeys/O/accounts/A/users/leaf.creds
|
|
},
|
|
]
|
|
}
|
|
</code></pre>
|
|
<p>Note the leaf node configuration lists a number of <code>remotes</code>. The <code>url</code> specifies the port on the server where leaf node connections are allowed. The <code>credentials</code> configuration specifies the path to a user's credentials file.</p>
|
|
<p>Create a subscriber on the leaf:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-sub -s localhost:4111 ">"
|
|
Listening on [>]
|
|
</code></pre>
|
|
<p>Publish a message on the server:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-pub -creds ~/.nkeys/O/accounts/A/users/leaf.creds foo foo
|
|
Published [foo] : 'foo'
|
|
</code></pre>
|
|
<p>Both the server and leaf subscriber print:</p>
|
|
<pre class="language-"><code class="lang-text">[#1] Received on [foo]: 'foo'
|
|
</code></pre>
|
|
<p>Publish a message on the leaf:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-pub -s localhost:4111 bar bar
|
|
Published [bar] : 'bar'
|
|
</code></pre>
|
|
<p>Both the server and leaf subscribers print:</p>
|
|
<pre class="language-"><code class="lang-text">[#2] Received on [bar]: 'bar'
|
|
</code></pre>
|
|
<p>The leaf forwards all local messages to the server where members of the account are able to receive them. Messages published on the server by the account are forwarded to the leaf where subscribers are able to receive them.</p>
|
|
<h3 id="leaf-authorization"><a name="leaf-authorization" class="plugin-anchor" href="#leaf-authorization"><i class="fa fa-link" aria-hidden="true"></i></a>Leaf Authorization</h3>
|
|
<p>In some cases you may want to restrict what messages can be exported from the leaf node or imported from the account. For leaf servers this is simply a user account configuration, as users can have specific permissions on what subjects to publish and/or subscribe to.</p>
|
|
<p>Let's put some restrictions on the <code>leaf</code> user so that it can only publish to <code>foo</code> and subscribe to <code>bar</code>:</p>
|
|
<pre class="language-"><code class="lang-text">> nsc edit user -n leaf --allow-pub foo --allow-sub bar
|
|
Updated user creds file "~/.nkeys/O/accounts/A/users/leaf.creds"
|
|
Success! - edited user "leaf" in account "A"

</code></pre>
|
|
<p>As we can see on the inspection of the user, the restrictions have been applied.</p>
|
|
<p>Let's repeat the experiment. This time we'll restart the leaf server so that the new user configuration is applied:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-server -c leaf.conf
|
|
</code></pre>
|
|
<p>You should see a new message on the leaf subscriber:</p>
|
|
<pre class="language-"><code class="lang-text">Reconnected [nats://localhost:4111]
|
|
</code></pre>
|
|
<p>Let's publish a message on the leaf:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-pub -s localhost:4111 foo foo
|
|
Published [foo] : 'foo'
|
|
</code></pre>
|
|
<p>You should see a new message in all your subscriber windows:</p>
|
|
<pre class="language-"><code class="lang-text">[#3] Received on [foo]: 'foo'
|
|
</code></pre>
|
|
<p>Now publish a new message on the leaf, but this time with the subject <code>bar</code>:</p>
|
|
<pre class="language-"><code class="lang-text">> nats-pub -s localhost:4111 bar bar
|
|
Published [bar] : 'bar'
|
|
</code></pre>
|
|
<p>This time only the leaf subscriber will print <code>[#4] Received on [bar]: 'bar'</code>, the account subscriber won't print it because the leaf user doesn't have permissions to publish on 'bar'.</p>
|
|
<p>Let's try the flow of messages from the server to the leaf node:</p>
|
|
<pre class="language-"><code>> nats-pub -creds ~/.nkeys/O/accounts/A/users/leaf.creds foo foo
|
|
Published [foo] : 'foo'
|
|
</code></pre><p>Only the server subscriber will receive the message as expected.</p>
|
|
<p>Repeat the publish this time with 'bar':</p>
|
|
<pre class="language-"><code>> nats-pub -creds ~/.nkeys/O/accounts/A/users/leaf.creds bar bar
|
|
Published [bar] : 'bar'
|
|
</code></pre><p>Both subscribers will receive the message as expected.</p>
|
|
<p>As you can see:</p>
|
|
<ul>
|
|
<li>Messages to and from the leaf node to the server are limited by the user associated with the leaf node connection.</li>
|
|
<li>Messages within the leaf node are as per the server's authentication and authorization configuration</li>
|
|
</ul>
