Docker container running latest-full returns blank web page #2273

Closed instantdreams closed 1 year ago

instantdreams commented 1 year ago

Describe the bug Starting the docker container results in a running container, but accessing the server web page at http://[server]:61208/ results in a blank web page with the following HTML:

<!DOCTYPE html>
<html>

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Glances</title>

    <link rel="icon" type="image/x-icon" href="favicon.ico" />
    <script>
      window.__GLANCES__ = {
        'refresh-time': '2'
      }
    </script>
    <script src="glances.js" defer></script>

</head>

<body>
  <div id="app"></div>
</body>
</html>

To Reproduce Steps to reproduce the behavior:

  1. Create a docker-compose.yml file with the following content:

    version: "3.5"
services:
glances:
image: nicolargo/glances:latest-full
container_name: ${CONTAINER_NAME}
hostname: ${CONTAINER_NAME}.${HOSTNAME}
network_mode: host
privileged: true
pid: host
# ports:
#   - 61208:61208 # web ui
environment:
  - TZ=${TZ}
  - GLANCES_OPT=--webserver --config /glances/conf/glances.conf
volumes:
  - ${DIRECTORY_CONF}:/glances/conf
  - /var/run/docker.sock:/var/run/docker.sock:ro
restart: unless-stopped

  2. Create a .env file with the following content:

    CONTAINER_NAME=glances
HOSTNAME=[server]
TZ=[timezone]
DIRECTORY_CONF=/srv/glances/conf

  3. Launch container with the following command:

    docker compose --file /srv/glances/docker-compose.yml up --detach

Expected behavior The Glances webserver to render a web page with full monitoring details.

Screenshots n/a, text is more suitable and can be indexed and searched.

Additional context I have four headless servers running versions of Debian:

Here are their relative operating systems:

Running this without a conf file or with a conf file results in the same result. I've read the documentation, and I've searched the Google Groups and github issues with no significant luck.

What am I missing?

RazCrimson commented 1 year ago

@instantdreams Is this issue happening on all four of your machines?

I am not able to replicate this on my end.

Also can you also share the details regarding which browser was used? Did you try with multiple browsers (if you did please mention the names too)?

instantdreams commented 1 year ago

It's happening on all four machines.

I've tried with latest Chrome and latest Firefox.

nicolargo commented 1 year ago

@instantdreams as @RazCrimson i can not reproduce the issue on my side.

Can you please try to clean your browser cache (using CTRL+F5) ?

If it did not work, edit your docker-compose.yml file in order to enable the debgug mode:

GLANCES_OPT=--webserver --config /glances/conf/glances.conf -d

Then restart the container and pastebin us the glances.log file.

Thanks !

instantdreams commented 1 year ago

Will do.

instantdreams commented 1 year ago

I fully refreshed an instance of Edge and all four work now!

Here's the log from one of them: https://pastebin.com/4rv5ieRn

instantdreams commented 1 year ago

I think this issue was caused by shifting from image joweisberg/glances to image nicolargo/glances.

Lesson learned, fully refresh the browser with ctrl+shift+r after any significant update.

brunohenriquy commented 7 months ago

I am having the same issue, tried to reboot the server several times, cleared browser cache, tried on several browsers.

I can access the api, it returns data, but not the main page.

I've switched to a docker container, now it is running well.
