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

setting it like this doesnt connect

csd4ni3lOP•15mo ago

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

csd4ni3lOP•15mo ago

why? port is exposed

dash:
        image: mauricenino/dashdot:latest
        restart: unless-stopped
        privileged: true
        ports:
        - '6734:3001'
        environment:
            - DASHDOT_ENABLE_CPU_TEMPS=true
            - DASHDOT_ALWAYS_SHOW_PERCENTAGES=true
            - DASHDOT_CPU_POLL_INTERVAL=500
            - DASHDOT_RAM_POLL_INTERVAL=500
            - DASHDOT_NETWORK_POLL_INTERVAL=500
            - DASHDOT_SPEED_TEST_INTERVAL=60
        volumes:
        - /:/mnt/host:ro

dash:
        image: mauricenino/dashdot:latest
        restart: unless-stopped
        privileged: true
        ports:
        - '6734:3001'
        environment:
            - DASHDOT_ENABLE_CPU_TEMPS=true
            - DASHDOT_ALWAYS_SHOW_PERCENTAGES=true
            - DASHDOT_CPU_POLL_INTERVAL=500
            - DASHDOT_RAM_POLL_INTERVAL=500
            - DASHDOT_NETWORK_POLL_INTERVAL=500
            - DASHDOT_SPEED_TEST_INTERVAL=60
        volumes:
        - /:/mnt/host:ro

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

csd4ni3lOP•15mo ago

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

csd4ni3lOP•15mo ago

it works with internal port(the connect), but then fails to embed so it seems like, the connection is done on the backend and not in browser, and embed is done in browser only which is very bad which means its impossible to get this working it would only work if i set a custom dash dns record trying that out

Manicraft1001•15mo ago

No, it would also work if you used the IPv4. But a custom DNS record will work as well

csd4ni3lOP•15mo ago

so i was right only works with dns because docker compose assigns a whole new network and on that network my ip is a lot different and yes, ipv4 did not work

Manicraft1001•15mo ago

It should. Did you check the log?

csd4ni3lOP•15mo ago

this does not work

csd4ni3lOP•15mo ago

this does

csd4ni3lOP•15mo ago

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

Manicraft1001•15mo ago

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

csd4ni3lOP•15mo ago

(after dns record)

csd4ni3lOP•15mo ago

adguard home

csd4ni3lOP•15mo ago

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. 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

Manicraft1001•15mo ago

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

csd4ni3lOP•15mo ago

yes, docker compose does that by default. just wanted to say that you should point that out in docs if its not already

is this enough in installation?

Just create a pull request and we'll give feedback there
