	port: 8080,
	ipWhitelist: [],
	language: "en",
	timeFormat: 24,
	units: "metric",

@raywo no

@raywo The config.js.sample was created automatically. After that i copy it to config.js and restarted container but logs show:

@raywo i tried

docker run  -d \
                        --publish 8080:8080 \
                        --restart always \

                        --volume ~/magic_mirror/modules:/opt/magic_mirror/modules \
                        --name magic_mirror \
                        bastilimbach/docker-magicmirror

docker ps

cat config.js

var config = {
	address: "localhost", // Address to listen on, can be:
	port: 8080,
	ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1", "192.168.1.176"],
	language: "en",
	timeFormat: 24,
	units: "metric",

	modules: [
		{
			module: "clock",
			position: "top_left"
		},
	]

};

When im trying to access url http://localhost:8080/ in incognito i got always “localhost didn’t send any data” and there is no information in container about trying to access pare.

@raywo I know that this is strange behaviour of MM and your fix is not according to documentation. I tried that but that fix doesn’t work at all. Additional think is that I’am running container on my mac and i cannot access MM from mac. 192.168.1.176 is my mac local ip. I want to develop new module but i don’t want to do this on rpi.

var config = {
	address: "localhost",
	port: 8080,
	ipWhitelist: [ "127.0.0.1", "::ffff:127.0.0.1", "::1", "192.168.1.176"],
	language: "en",
	timeFormat: 24,
	units: "metric",

	modules: [
		{
			module: "alert",
		},
		{
			module: "updatenotification",
			position: "top_bar"
		},
		{
			module: "clock",
			position: "top_left"
		},
	]

};

Hi i have problem with magic mirror. I started it inside docker container on rpi the MM is working ok. When i try to use docker container on mac or linux there will be no errors but also there will be no MM page under url.
