SENSOR container not initializing/installing properly.

[lnxredir]

I'm getting the following errors on the sensor container:

> sensor1@0.0.1 start

> node index.js

TypeError: Cannot read properties of undefined (reading 'value')

    at IncomingMessage.<anonymous> (/code/index.js:65:80)

    at IncomingMessage.emit (node:events:525:35)

    at endReadableNT (node:internal/streams/readable:1359:12)

    at process.processTicksAndRejections (node:internal/process/task_queues:82:21)

The installation was done using the official method, the web container displays this: Invalid Host header My docker compose version is: v2.14.2 and my docker version is: 20.10.22

[rob-mosher]

Thank you for your detailed bug report, @lnxredir

What OS and version of that OS are you using?

[lnxredir]

Ah, sorry, forgot about that. Ubuntu Server 20.04

[rob-mosher]

All good! Are you using a GUI, and is so, which? What was your process for installing Docker?

[lnxredir]

No GUI involved, just doing the curl https://raw.githubusercontent.com/oslabs-beta/docker-watch-app/main/install.yaml | docker-compose -p dockerwatch -f - up -d command as shown, I then try check the logs (using portainer and cli) and get the issue above, weird eh?

[rob-mosher]

Thank you. If you could also share your process for installing Docker it would be helpful in assisting. Our product depends on Docker being installed, as it utilizes the docker socket, typically found at /var/run/docker.sock on *nix-based OS's.

Ingestion of the metrics will require a web browser, which likely requires a GUI unless you have port forwarding manually configured in some way. I suppose CURLing localhost could work but the graphs would likely not be legible as we're using React.

[lnxredir]

It's fine, the process I used is the official docker installation method, using the latest version, I have other containers that use the privileged flag and they work fine, maybe my version of docker is too recent?

[rob-mosher]

Thank you. I'm spinning up an Ubuntu Server 20.04 VM to experiment on. Will follow up.

[lnxredir]

Thank you so much for the support man, if there's anything I can help with or information to give just hit me up.

[lnxredir]

Ah, something I just remembered, if I run the install using docker-compose I get this error: ERROR: Version in "None" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under theserviceskey, or omit theversionkey and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

I already know about this from other compose files that require new compose versions, if I run it using docker compose instead, it runs normally but the error persists.

EDIT The same error persists if I downgrade the docker version, allowing the old docker-compose command to work.

[rob-mosher]

Thank you for the additional information. I'll try with docker-compose and docker compose to see where it gets me.

[rob-mosher]

I've installed the Ubuntu 20.04 VM and am troubleshooting.

For next steps, from the terminal, what response do you get when running curl localhost:8854/api/v1/containers? It should be something like

[{"name":"/dockerwatch-db-1","id":"c478dd5a57e08b53c12a04a27f97753040e6d916cd205f107885ec5d043621a9"}]

Also, I wish to correct myself that the stats can be viewed from any other host on your network/subnet by visiting your host-ip on port 8855 via a web broswer. We may lock this down (or make it on option) in future versions.

Continuing to investigate the sensor1 issue.

[lnxredir]

From this specific command I got a few more options on my output, Ill just post the relevant ones.

{"name":"/dockerwatch-db-1","id":"3e026b58cfc61fb6db3a79dbfb9f70b9906e17b5dbe69217183bf9c1c5be4cb4"} {"name":"/dockerwatch-web-1","id":"9282d3e10b35e0515deab3f8836514fe7d65078da3b9f2ad61e9965da8a9d601"} {"name":"/dockerwatch-api-1","id":"9d699284c68737a4fc1b1b47850456f0f2f81d2d3c19e342a0714ebf86088122"}

Note that docker-sensor is not present on the list.

[rob-mosher]

Thank you. I was able to get the sensor working on my VM, however it is throwing the following errors:

TypeError: Cannot read properties of undefined (reading 'value')
    at IncomingMessage.<anonymous> (/code/index.js:65:80)
    at IncomingMessage.emit (node:events:525:35)
    at endReadableNT (node:internal/streams/readable:1359:12)
    at process.processTicksAndRejections (node:internal/process/task_queues:82:21)

I believe the next course of action is the Docker Watch team adjusting the software so that it works on Ubuntu 20.04 (the VM I just spun up), and from there taking further steps with you. It's possible that resolving the issue I'm able to produce may resolve your issue, but if not we'll take next steps with you from there. I'll coordinate with the team on Tuesday for next steps, as we are observing MLK day tomorrow.

Adding bug tag to issue.

[lnxredir]

Okay, thanks man, really appreciate all the support! Thanks for everything, Ill wait for a response back and happy MLK day for you and the team. Cheers!

[rob-mosher]

Thanks very much for your patience, @lnxredir ! Spoke with the team and the next window we have to continue troubleshooting this is on Sunday. We will follow up with you then.

[lnxredir]

Small update, I managed to get the sensor working properly, I did a 'wipe' of everything related to dockerwatch and re-run the compose and it's now up, now however the web container shows Invalid Host header.

And again, thanks for the support and sorry if I'm bothering the team too much.

[rob-mosher]

Thank you so much for your coordination on this @lnxredir, and we appreciate your patience. I've created a temporary branch for troubleshooting the most recent issue you reported. I believe that setting --allowed-hosts all in the package.json file may resolve the issue. Please purge docker-watch from your system and run the below, which includes these temporary changes:

git clone --single-branch --branch bugfix/issue-41 https://github.com/oslabs-beta/docker-watch-app.git
cd docker-watch-app
docker compose -p dockerwatch -f install.yaml up -d

[lnxredir]

Hey, thanks for the response! The webpage opens correctly now, however the sensor container is displaying an error still (different error than last time at least) and the web page shows no graphs.

It repeats this message over and over, here's a screenshot of the webpage.
