Percona for MongoDB Docker with Secrets

MongoDB Percona Server for MongoDB

I’m attempting to create a Percona for MongoDB container with Docker compose. I want to use secrets and looking through the Percona Dockerfiles I see that specifying the _FILE suffix of a variable allows this just like the regular mongo image.

However, if I launch the percona image with a secret added to the service (regardless of any other settings), it fails to launch and gives me this error:

Error response from daemon: getent unable to find entry "1001" in passwd database

The compose file is simply:

version: '3.9'
services:
  settings_db:
    image: percona/percona-server-mongodb:6.0.4-3
    container_name: test_percona
    secrets:
      - source: mongo_auth
        target: mongo_auth

secrets:
  mongo_auth:
    environment: SETTINGS_DB_PASSWORD

Every combination of changing the user, uid and gid on the secret or the service seem to have no effect (changing the user alters the error to say what you set instead of 1001).

Recently, I discovered that this is directly caused by using environment on the secret. If I use file instead, then this error does not occur. However, I am looking to use environment variables to inject the password from a common .env file.

Has anyone seen this issue before? I appreciate any insight
