Nginx isn't starting

[peterclemenko]

On the latest master Nginx isn't starting on windows

[peterclemenko]

current docker stack services, it's been like this since I tried 30 minutes ago

[peterclemenko]

Walkoff appears to have been broken on Windows since beta 1 was released. Can this please be fixed so it can be stable tagged as working on Windows? I'm trying to build an app that uses Walkoff as the automation layer and even if I can manage to get it working temporarily, it's unshippable if there is no stable dependency that runs.

[iadgovuser11]

Does this still tie in with the last issue? We had changed the windows setup to mirror the linux setup so try using the walkoff.ps1 installation. The installation instructions need to be updated and the old windows_setup.ps1 need to be deleted apologies for the oversight. You should be able to use the bootloader using the same commands at the Linux version if you use walkoff.ps1. So for example walkoff.ps1 up --build and walkoff.ps1 down should work. Let us know if this solves the problem or its something else.

[peterclemenko]

I'm not sure if this ties in to the last issue or not. walkoff.ps1 isn't working. This report is based on walkoff.ps1

[peterclemenko]

Looking at the logs from #239, I wonder if it's a symptom of the same issue.

[adpham95]

The logs from #239 are due to running walkoff_setup.ps1 instead of walkoff.ps1 (there was an errant :5000 left over in the command retrieving the host's DockerNAT IP) - I'll push that deletion to master soon.

For this one, could you post the results of docker service ps service_name --no-trunc for the services that are at 0/1?

• walkoff_resource_nginx
• walkoff_core_umpire
• walkoff_core_api_gateway

Additionally, are you using Docker for Windows (Hyper-V backend) or the older Docker Toolbox for Windows (Virtualbox backend)? @iadgovuser11 and I are using the former for testing on Windows. I can try and get the latter set up to try and replicate if that is the case.

[peterclemenko]

I'm on the hyper v backend.

[peterclemenko]

Not sure what's breaking these

[iadgovuser11]

Try walkoff.ps1 up --build it should re-download and build the images that are missing

[peterclemenko]

Already tried that with no luck.

[peterclemenko]

Interestingly enough, walkoff.ps1 down seems to be rebuiliding everything and not working either. Seems like down isn't actually executing, and executes the same as up

[adpham95]

Could you provide the output for what you're seeing? I'm unable to replicate that behavior on Windows.

[peterclemenko]

Yeah, correction on the down one, that was my misreading it. Sorry, I'm out of it today.

Build didn't fix the problem though.

[adpham95]

While the walkoff_resource_registry service is running, In PowerShell, can you run curl http://localhost:5000/v2/_catalog | Select-Object -ExpandProperty Content and send the output?

Additionally, the images that the docker service ps gave you, are those present when you do docker images?

[peterclemenko]

I'm in the process of doing it. Also, I notice the following at the end of every time I start walkoff.ps1 with up.

2019-09-06 06:44:12,579 - UMPIRE - INFO:Docker connection closed.

could the docker connection closing cause part of this?

[iadgovuser11]

the docker connection closed is standard bootloader output. It just means the bootloader connection closed.

i can open localhost:5000 in a browser, the page is blank. no error though.

[adpham95]

So it looks like it's failing somewhere in the build process - only walkoff_app_sdk is showing up. When you do walkoff.ps1 up --build --debug what output do you see?

[peterclemenko]

This is the build output
out.txt

[peterclemenko]

I attached the build output above

[adpham95]

Sorry, I'm kind of at a loss. Nothing in that build output suggests that it's having trouble building or pushing, but your docker images and curl output show that all of the images are missing except app_sdk. Was the behavior the same (docker service ps showing missing images) after that latest build?

Is there anything that might be cleaning up images on your system? If you manually build something and then push it to WALKOFF's registry while it's running, does it show up in docker images and the registry catalog? For example:

# Inside the WALKOFF directory
docker build -f api_gateway/Dockerfile -t 127.0.0.1:5000/api_gateway .
docker push 127.0.0.1:5000/api_gateway
.\walkoff.ps1 down --debug
.\walkoff.ps1 up --debug 

[peterclemenko]

So doing that I now have the nginx and web interface

[peterclemenko]

So it's working now. I'm not sure if I should close the issue or not, but my gut tells me there's a deeper issue here.

[peterclemenko]

So I just did a clean install and I had to do the manual build and push again. Shouldn't this be automated?

[adpham95]

I just moved my development environment out of a Ubuntu VM and into Windows. Even on a clean install it still builds and pushes as expected in the walkoff.ps1 script, so I'm not really sure what the issue might be on your end. We're wrapping up some efforts for a release over the next few days, I'll get back to this once we release.

[peterclemenko]

Alright, I'm going to look in to this on my end. A hack might be needed, if I can fix it on my end, I'll send a pull request.

[peterclemenko]

Also, I have a theory that #245 might be related to this as well. If something is screwed up with the way it works on my machine (which is weird because docker usually works, but for some reason it stopped working right around the time the bootloader got implemented), it might be causing some kind of issue with how the push is handled. I don't know what would cause it though, as I'm running the latest docker for windows in a relatively vanilla windows 10.

[peterclemenko]

Wait a second, just tested development branch and it seems to work out of the box.

#245 still seems to be a problem though. I'm wondering if it's related.

[peterclemenko]

I'm going to close this issue for now. #245 seems to be having similar issues but for everything but bootloader and the api gateway. I have no idea why.

[peterclemenko]

Wait, I think I was wrong.

[peterclemenko]

Yeah, I was wrong, it's still broken. I need to tear in to this.

[peterclemenko]

Out of curiosity, what version of windows are you running, is it the latest patch set? Also are you running the latest docker for windows. I'm doing all that, also I'm running it from both my d drive and my desktop.

I use this to set up my desktop when I create a new one. I do add a few things after that (mainly games), but this is the bulk of it.

So on latest master and dev I've been able to replicate this and umpire is doing the same thing as gateway.

I've done this on two windows 10 boxes. A desktop and a laptop. The laptop I can at least work around it by manually pushing, but the desktop manually pushing gives me an internal server error.

Are you still experiencing the same issue? To follow up from a few months ago, it was tested on three machines, one on 1809, one on the latest build of Win10 at the time, and another on the fast ring insider build of Win10 20H1 at the time. All had the latest version of Docker for Windows at the time.

Not trying to deflect but it still feels like the issue is more likely to be in configuration of Docker or network settings.

My debug steps would be:

• Check docker stack services walkoff for failing services
• Check docker service ps servicename --no-trunc for the exit codes for a failing service
• Check docker service logs -f servicename for the logs on a failing service.

Can only really get an idea of what's going on with all three of those from a particular failed deployment.

So I was able to get it to work on Linux, however it appears the latest builds are not properly building using the ps1 script in git. It actually errors out when trying to run it on my end. First it refuses to create walkoff network, then it refuses to build other images and stand them up. It seems that the core images are the ones not loading up. I can test again and post logs, I'll open another issue for it.

I have no idea what's causing it. It's even happening on a fresh windows 10 install for me with nothing but the stuff in the install script here:
https://github.com/aoighost/newwin10installscript

using windows terminal and powershell core from the script

I know you're not trying to deflect, it seems like it works for everyone but me. If I can find out what's causing it, it would make my life a lot easier. For now though I'm exploring kubernetes and argo as an alternative for walkoff for my project. I can't keep putting off dev for this.

Hi @AoiGhost,
I'm running WALKOFF on CentOS and I just ran into the same issue as you. There's no way I can explain it and it drove me crazy for days! Clean install over and over again and I just couldn't get it to work. Exact same configuration somewhere else and it works.

Thanks to all of your investigation, I fixed it following your steps :

docker build -f umpire/Dockerfile -t 127.0.0.1:5000/walkoff_core_umpire .
docker push 127.0.0.1:5000/walkoff_core_api
docker build -f umpire/Dockerfile -t 127.0.0.1:5000/walkoff_core_umpire .
docker push 127.0.0.1:5000/walkoff_core_umpire
docker build -f socketio/Dockerfile -t 127.0.0.1:5000/walkoff_core_socketio .
docker push 127.0.0.1:5000/walkoff_core_socketio
./walkoff.sh up --build

I cannot explain it either. It was working fine the day before, the next day I couldn't anymore. Well, if anybody knows someday.. anyway, thanks to all of you!

I faced a similiar issue on Debian 9.

Nginx was failing on

2020/08/27 09:11:59 [emerg] 1#0: host not found in upstream "core_api" in /opt/bitnami/nginx/conf/server_blocks/walkoff.conf:10
nginx: [emerg] host not found in upstream "core_api" in /opt/bitnami/nginx/conf/server_blocks/walkoff.conf:10

I ran

docker build -f umpire/Dockerfile -t 127.0.0.1:5000/walkoff_core_umpire .
docker build -f api/Dockerfile -t 127.0.0.1:5000/walkoff_core_api .
docker build -f socketio/Dockerfile -t 127.0.0.1:5000/walkoff_core_socketio .
./walkoff.sh up

core_api was then failing and another bug, but not directly related - #272

Rebuilding the images helped 🎉
Thanks!

So I've moved to Shuffle which supports walkoff apps and is actively developed, in case anyone is looking for help with this

@AoiGhost see #273

This fixed the problem for me.
