nginx not configured

[samyhocine]

Hi,

I'm on Win10 Home and I use docker Toolbox.

I've followed the installation guide but I'm facing an issue. Working on since two days but didn't find a way to solve it :/

When I connect to "http://192.168.99.100:8080" on Google Chrome I have the nginx homepage with this message:

"Welcome to nginx!
If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

For online documentation and support please refer to nginx.org.
Commercial support is available at nginx.com.

Thank you for using nginx."

So nothing has been configured and I can't access the login page.

How is it so ?

The build went well and everything is green "done" when doing docker-compose up -d

For information:

I've modified the file docker-compose.yml (because I'm using Docker Toolbox)

cvat_proxy:
...
    environment:
        CVAT_HOST: "192.168.99.100"

And also updated the cvat-ui/package.json file with:

"scripts": {
    "build": "webpack --max-old-space-size=8192 --config ./webpack.config.js",

To increase the available mem space because of an issue I had during the build: "JavaScript heap out of memory" (issue solved with this update)

Best regards,

Samy

Is this a trivial problem ?

@samyhocine Hi, sorry for the late response. We did't try to build and use CVAT with docker toolbox, but could you please run the following command and attach cvat_proxy.conf file?

docker cp cvat_proxy:/etc/nginx/conf.d/default.conf cvat_proxy.conf

[samyhocine]

@azhavoro thanks for your feedback.

This line didn't help unfortunately. I tried this command before a:

docker-compose up -d

And before a "rebuilt": docker-compose build

The cvat_proxy.conf file (markdown is a bit lost with the syntax analysis :/)

server { listen 80; server_name _ default; return 404; }

server { listen 80; server_name 192.168.99.100;

location ~* /api/.*|git/.*|tensorflow/.*|auto_annotation/.*|analytics/.*|static/.*|admin|admin/.*|documentation/.*|dextr/.*|reid/.*  {
    proxy_pass              http://cvat:8080;
    proxy_pass_header       X-CSRFToken;
    proxy_set_header        Host $http_host;
    proxy_pass_header       Set-Cookie;
}
location / {
    # workaround for match location by arguments
    error_page 418 = @annotation_ui;

    if ( $query_string ~ "^id=\d+.*" ) { return 418; }

    proxy_pass              http://cvat_ui;
    proxy_pass_header       X-CSRFToken;
    proxy_set_header        Host $http_host;
    proxy_pass_header       Set-Cookie;
}

# old annotation ui, will be removed in the future.
location @annotation_ui {
    proxy_pass              http://cvat:8080;
    proxy_pass_header       X-CSRFToken;
    proxy_set_header        Host $http_host;
    proxy_pass_header       Set-Cookie;
}

}`

@samyhocine could you post output from docker-compose config and docker ps also?

[samyhocine]

@azhavoro here we go :)

docker_ps_res.txt

dockercompose_config_res.txt

[azhavoro]

It's very strange, everything looks ok ... nginx homepage points that it uses default config, but config is properly configured. Could you attach your docker-compose.yml? I'll try to reproduce the issue on windows.

[samyhocine]

Thanks a lot :)

Attached docker-compose.yml (.txt for the upload)

I have the same issue from Ubuntu 18.04 VM, so I follow...

[azhavoro]

@samyhocine @yohayonyon Hi, could you please attach the output from the following commands
docker exec -it cvat_proxy -T and docker exec -it cvat_ui -T? Also docker logs cvat_proxy and docker logs cvat_ui may be helpful. Thanks.

[azhavoro]

One more question: is the admin page http://192.168.99.100:8080/admin reachable?

[samyhocine]

@azhavoro

docker_exec_it_cvat_proxy_T.txt

docker_exec_it_cvat_ui_T.txt

docker_logs_cvat_proxy.txt

docker logs cvat_ui returns Nothing

Yes, http://192.168.99.100:8080/admin is reachable. I can see the Django administration login panel.

[azhavoro]

@samyhocine sorry, right command is docker exec -it cvat_proxy nginx -T and docker exec -it cvat_ui nginx -T

[samyhocine]

Sorry @azhavoro

I've just switched on Windows 10 Pro.

Maybe @yohayonyon would like to continue

Thanks again @azhavoro for your time ;)

[azhavoro]

@samyhocine I think it's not related with docker toolbox, there is the same issue on ubuntu #1287. Looks like that cvat_ui not properly configured by some reason and returns default nginx page. Unfortunately I cannot reproduce the issue at the moment...

[samyhocine]

Oh ok :/

I will clone the git and try it on my Windows 10 Pro

[samyhocine]

@azhavoro I've installed cvat on Windows 10 Pro using Docker Desktop and it's working.

Maybe it's docker related and not cvat related ?
My processor (if it's useful): AMD Ryzen 5 2600

@yohayonyon for the next move ? :)

[yohayonyon]

1. <machine_name>:8080/admin - django login screen was reached. I managed to log in with the superuser credentials that I had defined.

2. docker exec -it cvat_proxy nginx -T - cvat_proxy.txt

3. docker exec -it cvat_ui nginx -T - cvat_ui.txt

4. docker exec -it cvat_ui cat /usr/share/nginx/html/index.html - index.html.txt

Seems similar to issue #1287.

[azhavoro]

@yohayonyon thanks, yes it's the same issue, could you please rebuild cvat_ui image with the command docker-compose build --no-cache cvat_ui and attach full build log? Thanks.

[yohayonyon]

So far it is stuck there...

#1261

@nmanovic , I have found two issues with the deployment:

• nginx proxy cannot work by default with long domain names (e.g. ec2-x-xx-xx-xxxx.us-east-2.compute.amazonaws.com). Need to specify a directive to resolve the issue. If you have the problem it is easy do diagnose. Just run docker logs cvat_proxy and you will see the recommendation from nginx.
• When cvat-ui is complied there is a problem with memory consumed by nodejs. Some problems can be solved by use NODE_OPTIONS=--max_old_space_size=200 environment variable. But webpack consumes too much memory. It leads to "JavaScript heap out of memory" problem (webpack/webpack#6389).

Our team will do the best to resolve the issue ASAP.

P.S. I tried to reproduce the issue on t2.micro with 1G RAM.

[muhammadhusein]

I also have the same problem, I'm using ubuntu OS 18.04 ...
how do i fix it?
Please..

[lbj96347]

@muhammadhusein I have met the same issue when I install CVAT on Ubuntu OS 18.04. When I type curl http://localhost:8080/admin , I'm not able to reach django admin.

I realized that cvat_ui may not ready for using. So I ran docker-compose build --no-cache cvat_ui again. After that I try to run docker-compose up -d, it works now.

[luvwinnie]

it shows the same problem in macOS Catalina....., the root path goes to the Nginx default page.. Did anyone have the solution?
