   @richvdh Thanks. Yes, your examples worked for me also.

   I'm using the following docker-compose.yml

   version: '3'
   services:
     synapse:
       build:
           context: ./
           dockerfile: Dockerfile
       image: matrixdotorg/synapse:latest
       restart: unless-stopped
       volumes:
         - ./etc:/etc
         - ./data:/data
       depends_on:
         - synapse-db
       ports:
         - 8008:8008/tcp
   
     synapse-db:
       image: postgres:10-alpine
       environment:
         - POSTGRES_USER=synapse
         - POSTGRES_PASSWORD=xxxxxxxxxxxxxxxxxxxxxxxxxxxx
       volumes:
         - ./schemas:/var/lib/postgresql/data

   I'm not that familiar with docker-compose, but does this mean you are building your own docker image?

       build:
           context: ./
           dockerfile: Dockerfile
   

   I'd suggest you are adding a library that is linked against the wrong version of python.

     synapse-db:
       image: postgres:10-alpine
   

   I don't know if it matters, but the synapse image was switched to debian in #7839

   The build section is only triggerd by using docker-compose build. If you provide an image inside the yml file the build section will be skipped.

   I took this compose file from

   https://github.com/matrix-org/synapse/blob/b2b86990705de8a099093ec141ad83e09f182034/contrib/docker/docker-compose.yml

   @clokep Hm...the error occurs inside the synapse container, not the synapse-db container...Even if I choose

   image: postgres:10

   it doesn't work.

   I'd suggest asking on #synapse:matrix.org if anyone is using docker compose with Synapse and have a working config. If so, it'd be great to update the one in our contrib directory.

   @clokep Talking on #synapse:matrix.org the problem seems to be this mount:

     - ./etc:/etc
   

   which seemed to work with the alpine image, but not the debian one. So I think this can be closed. Thank you all.
