Hi!

I'm getting an error while installing mercury from docker file from https://github.com/mljar/mercury.git using instruction https://runmercury.com/docs/docker-compose/, could you pls help?

Step 8/17 : RUN mamba install --yes python=3.8 --file mercury/requirements.txt -c conda-forge

Hi @catabram,

Did you manage to solve the issue? Do you have more logs?

[catabram]

Hi Piotr!

No, haven't managed yet, but found some relevant info in mamba: https://mamba.readthedocs.io/en/latest/user_guide/troubleshooting.html#libmamba-so-2-undefined-symbol. It seems some conflicts with default mamba & conda-forge, tried recepy from here, as well python 3.8 not working now. Tried with python 3.10, got this and errors in network:

Thanks for response @catabram, looks like server is working because you have screenshot with API viewer. It is a good sign. Have you customised nginx configuration? Are you able to attach your nginx config? Because it looks like frontend is not displayed, which might be caused by improper nginx config.

@pplonski Hi! There's nginx config (I have external one insead of included in docker):

server {
  listen  80;
  server_name mercury.----host----;
  return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl;
    server_name mercury.----host----;
    server_tokens off;

    ssl_certificate /etc/nginx/ssl/mercury.----host----/fullchain.pem;
    ssl_certificate_key /etc/nginx/ssl/mercury.----host----/privkey.pem;

    }

    location /api {
        try_files $uri @proxy_api;
    }
    location /admin {
        try_files $uri @proxy_api;

Thanks for nginx config. In the screenshot you are using port 9010, in ngnix you are not setting this port ... Is it working without port number?

@pplonski Hi! The container with mercury listens to port 9010 which is proxied to port 9000 inside the container. In our environment, port 9000 is already occupied, and we use an external nginx balancer.

I believe there have been changes in the python dependencies that can no longer be installed on python version 3.8. For the same reason, mercury is not working properly.

[pplonski]

You might be right, I have reports from that docker is not working with 3.8 https://github.com/mljar/mercury/issues/385

[pplonski]

I've updated the Dockerfile, please check #385.

[boryakbrk]

I've updated the Dockerfile, please check #385.

I applied these fixes initially, we still see the broken mercury interface. There are no errors in the container logs.

[pplonski]

Please double check your nginx configuration. Have you changed the port number in docker entrypoint script https://github.com/mljar/mercury/blob/main/docker/mercury/entrypoint.sh (line 37).

[catabram]

Hi, port set to 9010 at this line
