Unable to store secret: memcache: no servers configured or available

[eitch]

I am trying to run yopass in a docker compose environment. This is my compose file:

services:
  memcached:
    image: memcached
    restart: unless-stopped
    expose:
      - "11211"
  yopass:
    image: jhaals/yopass
    restart: unless-stopped
    expose:
      - 80
    environment:
      - TZ=Europe/Zurich
      - DISABLE_IPV6=true
    command: "--database memcached --memcached=memcached:11211 --port 80"
    networks:
      proxy-network:
        ipv4_address: 10.x.x.x
networks:
  proxy-network:
    external: true

The containers start but i don't see anything about the memcached being configured:

$ sudo docker compose up

I can bring up the UI, but storing gives me an error:

This is with the latest container as of today.
