<h1>Running multiple instances</h1>
|
||||
|
||||
<p>By default, Watchtower will clean up other instances and won't allow multiple instances running on the same Docker host or swarm. It is possible to override this behavior by defining a <a href="https://containrrr.github.io/watchtower/arguments/#filter_by_scope">scope</a> to each running instance. </p>
|
||||
<p>Notice that:
|
||||
- Multiple instances can't run with the same scope;
|
||||
- An instance without a scope will clean up other running instances, even if they have a defined scope;</p>
|
||||
<p>To define an instance monitoring scope, use the <code>--scope</code> argument or the <code>WATCHTOWER_SCOPE</code> environment variable on startup and set the <em>com.centurylinklabs.watchtower.scope</em> label with the same value for the containers you want to include in this instance's scope (including the instance itself).</p>
|
||||
<p>For example, in a Docker Compose config file:</p>
|
||||
<pre><code class="json">version: '3'
|
||||
|
||||
services:
|
||||
app-monitored-by-watchtower:
|
||||
image: myapps/monitored-by-watchtower
|
||||
labels:
|
||||
- "com.centurylinklabs.watchtower.scope=myscope"
|
||||
|
||||
watchtower:
|
||||
image: containrrr/watchtower
|
||||
volumes:
|
||||
- /var/run/docker.sock:/var/run/docker.sock
|
||||
command: --interval 30 --scope myscope
|
||||
labels:
|
||||
- "com.centurylinklabs.watchtower.scope=myscope"
|
||||
</code></pre>
