i have dash. like this in my docker compose where i also have homarr:

dash:
    image: mauricenino/dashdot:latest
    restart: unless-stopped
    privileged: true
    ports:
    - '6734:3001'
    volumes:
    - /:/mnt/host:ro

dash:
    image: mauricenino/dashdot:latest
    restart: unless-stopped
    privileged: true
    ports:
    - '6734:3001'
    volumes:
    - /:/mnt/host:ro

dash:
    image: mauricenino/dashdot:latest
    restart: unless-stopped
    privileged: true
    ports:

    - /:/mnt/host:ro

setting it like this doesnt connect

C

csd4ni3lOP•10/1/23, 8:08 AM

setting it internally, does not embed the stats, cause that dns record for dash doesnt exist outside of docker network.

You should set it to the absolute IP address. Both Homarr and your browser must be able to connect

M

Manicraft1001•10/1/23, 9:03 AM

Your browser can't connect to localhost nor the internal docker hostname

why?

C

csd4ni3lOP•10/1/23, 9:03 AM

port is exposed

Because localhost means the local host. The client tries to connect to itself. Unless your running Homarr and Dash. on the same machine as your browser is, this won't work

Ccsd4ni3l port is exposed

M

Manicraft1001•10/1/23, 9:04 AM

Then just use the IP and port instead of localhost or the internal Docker hostname

C

csd4ni3lOP•10/1/23, 9:05 AM

yes, i am doing exactly that right now, but i will use a raspi later

C

csd4ni3lOP•10/1/23, 9:06 AM

C

csd4ni3lOP•10/1/23, 9:06 AM

C

csd4ni3lOP•10/1/23, 9:07 AM

it works with internal port(the connect), but then fails to embed

C

csd4ni3lOP•10/1/23, 9:07 AM

so it seems like, the connection is done on the backend and not in browser, and embed is done in browser only

C

csd4ni3lOP•10/1/23, 9:07 AM

which is very bad

C

csd4ni3lOP•10/1/23, 9:07 AM

which means its impossible to get this working

C

csd4ni3lOP•10/1/23, 9:08 AM

it would only work if i set a custom dash dns record

Ccsd4ni3l it would only work if i set a custom dash dns record

C

csd4ni3lOP•10/1/23, 9:14 AM

trying that out

Ccsd4ni3l it would only work if i set a custom dash dns record

M

Manicraft1001•10/1/23, 9:15 AM

No, it would also work if you used the IPv4.

M

Manicraft1001•10/1/23, 9:15 AM

But a custom DNS record will work as well

C

csd4ni3lOP•10/1/23, 9:16 AM

so

C

csd4ni3lOP•10/1/23, 9:16 AM

i was right

C

csd4ni3lOP•10/1/23, 9:16 AM

only works with dns

C

csd4ni3lOP•10/1/23, 9:16 AM

because

C

csd4ni3lOP•10/1/23, 9:16 AM

docker compose assigns a whole new network

C

csd4ni3lOP•10/1/23, 9:16 AM

and on that network

C

csd4ni3lOP•10/1/23, 9:16 AM

my ip is a lot different

C

csd4ni3lOP•10/1/23, 9:17 AM

and yes, ipv4 did not work

Ccsd4ni3l and yes, ipv4 did not work

M

Manicraft1001•10/1/23, 9:17 AM

It should. Did you check the log?

C

csd4ni3lOP•10/1/23, 9:18 AM

this does not work

C

csd4ni3lOP•10/1/23, 9:18 AM

this does

C

csd4ni3lOP•10/1/23, 9:18 AM

C

csd4ni3lOP•10/1/23, 9:18 AM

as i said, your backend connects to the ip which is bad

Ccsd4ni3l Click to see attachment

M

Manicraft1001•10/1/23, 9:18 AM

No, it won't. Your client doesn't know this hostname

Ccsd4ni3l Click to see attachment

C

csd4ni3lOP•10/1/23, 9:18 AM

(after dns record)

C

csd4ni3lOP•10/1/23, 9:19 AM

adguard home

C

csd4ni3lOP•10/1/23, 9:20 AM

so, the problem is that your backend connects, and finds the ip from docker dns, but for browser to connect, it needs a custom dns record to work from its dns.
Backend doesnt connect with ipv4 because docker creates an isolated network for each docker compose setup which cant connect to local ips.
Browser could connect to that.

C

csd4ni3lOP•10/1/23, 9:22 AM

Backend:

can connect to docker services.
can't connect to local ipv4 because of network isolation
Frontend(Browser):
can't connect to docker services
can connect to local ipv4 because its on the router

M

Manicraft1001•10/1/23, 9:22 AM

Yes, that is true, if you use network isolation.

MManicraft1001 Yes, that is true, if you use network isolation.

C

csd4ni3lOP•10/1/23, 9:23 AM

yes, docker compose does that by default.

C

csd4ni3lOP•10/1/23, 9:23 AM

just wanted to say that you should point that out

C

csd4ni3lOP•10/1/23, 9:23 AM

in docs if its not already

is this enough in installation?
