<p>I want to create dataBase for autotest in kubernetes. I want to create an  image(postg-my-app-v1) from postgres image, add changelog files, and liquibase image. When I deploy this image with helm i just want to specify containers - postg-my-app-v1 and it should startup pod with database and create tables with liquibase changelog.</p>
<p>Now i create Dockerfile as below</p>
<pre><code>FROM postgres
ADD /changelog /liquibase/changelog
</code></pre>
<p>I don't understand how to add liquibase to this image? Or i must use docker compose? or helm lifecycle postStart for liquibase?</p>

<pre><code>FROM docker-proxy.tcsbank.ru/liquibase/liquibase:3.10.x AS Liquibase
