title: Postgres docker wants to execute random commands?
body: <p>I am running the postgres docker container on a M1 Mac</p>
  <p>MacOS Monterey Version 12.2.1</p>
  <pre class="lang-yaml prettyprint-override"><code>postgres:
    image: postgres:14.2-alpine
    environment:
      - POSTGRES_DB=reachmehere_project
      - POSTGRES_PASSWORD=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_HOST_AUTH_METHOD=scram-sha-256
      - POSTGRES_INITDB_ARGS=--auth-host=scram-sha-256
    volumes:
      - pgdata:/var/lib/postgresql/data
      - ./pg_data/logs:/var/logs
    ports:
      - &quot;5432:5432&quot;
    networks:
      customnetwork:
        ipv4_address: 172.20.0.11
  </code></pre>
  <p>When I start the container everything is good and <code>docker stats</code> shows me &lt; 1% CPU usage, but after like 30 minutes of doing nothing just sitting there it jumps to 200% and I see the following output in the container logs:</p>
