[DBS-1882] Exception

[suprovsky]

Describe the bug
Lynis does not detect a configuration file of Redis as it's not default one because all instances of Redis are run as Docker containers.

Version

• Ubuntu 24.04 LTS amd64
• Lynis 3.1.2

Expected behavior
A clear and concise description of what you expected to happen.

Output

Additional context
You can reproduce this with the following setup on Docker:
docker-compose.yml:

services:
  redis:
    image: rapidfort/redis:7.2
    healthcheck:
      test: redis-cli PING | grep PONG
      interval: 10s
      timeout: 2s
      retries: 10
    restart: always
    env_file:
      - ./.env
    environment:
      - REDIS_PASSWORD=${REDIS_PASSWORD}
      - REDISCLI_AUTH=${REDIS_PASSWORD}
    volumes:
      - redis-data:/bitnami/redis/data:rw
volumes:
  redis-data:

.env

REDIS_PASSWORD=testpw

The volume must have 1001:1001 permissions set in the volume, otherwise it won't start.
I do it in a way where I add command: sleep infinity to a service and then after upping services I do docker exec -i -u 0 containername chown -R 1001:1001 /bitnami/redis/data

[konstruktoid]

That means there needs to be some kind of container test as well, similar to

$ for p in $(pgrep redis); do if grep -q docker "/proc/${p}/cgroup"; then echo "${p} is in a container"; fi; done
46716 is in a container

And then this can scale of course (ignore or find config in container etc etc)
