FLower image hosted by docker outputs error 'failed to create shim task'

[brunolnetto]

Describe the bug

I use this repository content as reference for flower hosting. Since I am new to the tool, I wrote docker-compose file below to host on my machine:

services:
  redis:
    image: redis:7
    ports:
      - "6379:6379"

  flower:
      image: mher/flower:latest
      command: ['flower', '--broker=redis://redis:6379', '--port=5555']
      ports:
        - "5555:5555"
      depends_on:
        - redis

I got following error: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "flower": executable file not found in $PATH: unknown

To Reproduce

Steps to reproduce the behavior:

1. Go to repository https://github.com/brunolnetto/flower-strauss/blob/main/docker-compose.yaml and clone it OR create a file docker-compose.yaml with above content;
2. Host with Docker Desktop for linux users OR run command docker compose up --build -d on linux terminal;
3. See above reported message;

Expected behavior
I expected to host flower monitoring without hassle.
