Error: "flag provided but not defined"

[schenklklopfer]

I try to start your tool providing username and password for my selfhosted ntfy instance.
All I get is this error: flag provided but not defined

I tried several things but the error is always the same.
Maybe I just do not understand how to set this settings correctly.

Here the docker-compose.yml parts I use:

...
  grafana-ntfy:
    image: academo/grafana-ntfy:latest
    restart: unless-stopped
    expose:
      - 8080 #only accesible to other containers
    networks:
      - metrics
    command:
      - "-username 'grafana' -password 'super-secure-pw' -ntfy-url 'https://selfhosted-ntfy-server.tld/grafana'"

The message I get in full term is:

flag provided but not defined: -username 'grafana' -password 'super-secure-pw' -ntfy-url 'https://selfhosted-ntfy-server.tld/grafana'
Usage of /usr/local/bin/grafana-ntfy:
  -addr string
    	The address to listen on (default ":8080")
  -allow-insecure
    	Allow insecure connections to ntfy-url
  -debug
    	print extra debug information
  -ntfy-url string
    	The ntfy url including the topic. e.g.: https://ntfy.sh/mytopic
  -password string
    	The ntfy password
  -port int
    	DEPRECATED. Use listenAddr. The port to listen on (default 8080)
  -username string
    	The ntfy username

What is wrong here?

Hi there.

You are passing wrong the command, in docker-compose you need to pass each space-separated parameter as an element, so instead of (here you are passing a single big param with all the content inside escaped)

command:
      - "-username 'grafana' -password 'super-secure-pw' -ntfy-url 'https://selfhosted-ntfy-server.tld/grafana'"

you should use

    command:
      - "-username"
      - "grafana"
      - "-password"
      - "super-secure-pw"
      - "-ntfy-url"
      - "https://selfhosted-ntfy-server.tld/grafana"

or you can also not use an array for the command and pass a string directly

    command: -username grafana -password super-secure-pw -ntfy-url https://selfhosted-ntfy-server.tld/grafana

You can see how it works in the docker docs

I tried those commands I gave you here locally and they all work fine

I also updated the readme to avoid confusing people with the format in the future
