Airflow shows "Log Url" localhost:8080, although I am using airflow behind nginx proxy on hostname:443 port

[raulk89]

Apache Airflow version: 1.10.11, 1.10.12

Environment: Virtual machine

• OS (e.g. from /etc/os-release): CentOS Linux release 7.8.2003 (Core)
• Kernel (e.g. uname -a): 3.10.0-1127.18.2.el7.x86_64
• Install tools: yum, pip3
• Others:

What happened: After executing DAG, I clicked on "running tasks", then opens up this page, where there is "Log Url" link. But this one does not open, since I am using it behind nginx proxy.

What you expected to happen: The "Log Url" should be "https://hostname:443/..."

How to reproduce it:

Just make sure that your ariflow webserver runs on http://localhost:8080, then
# yum install nginx

Add virtualhost conf and add the following:
You can probably get by with just using port 80 also, then you do not need ssl and certs
And then your application opens up http://hostname:80

vi /etc/nginx/conf.d/airflow_webserver_proxy.conf

server {
 listen 80;
 server_name hostname.domain.com;
 return 301 https://$host$request_uri;
}

server {
 listen 443 ssl http2;
 server_name hostname.domain.com;

 location / {
  proxy_pass http://localhost:8080;
  proxy_set_header Host $host;
 }

 ssl_certificate /etc/pki/tls/certs/<<location to .cer file>>;
 ssl_certificate_key /etc/pki/tls/private/<<location to .key file>>;

 ssl_session_timeout 60m;
 ssl_dhparam /etc/ssl/certs/<<self signed cert>>;

 ssl_protocols TLSv1.2;
 add_header Strict-Transport-Security "max-age=31536000;" always;

}

# systemctl start nginx

And then open up web browser, start a random DAG, click on "running task" and then there should be this "Log Url"

Anything else we need to know: It happens always.

Well this :443 is omitted from the URL ofcourse, since it is https default port.
So URL is:
https://hostname.domain.com/...

What is your value for base_url option in webserver section ?

[raulk89]

http://localhost:8080 I am using rbac also (airflow.cfg file rbac = True) Haven't noticed that any other link is broken except this "Log Url". Raul

@raulk89 it should be set to https://localhost:8080.

@raulk89, hi, i have the same problem. Did you solve it? I try solutions from this issues, but it doesn't help me ..

The problem is in the link's href attribute, which includes the base URL (http://localhost:8080).

<td>
  <a href="http://localhost:8080/log?execution_date=2023-07-21T00..." data-original-title="" title="">
    <span class="material-icons" aria-hidden="true">reorder</span>
  </a>
</td>

A href="/log?execution_date=2023-07-21T00..." would solve this issue.

This URL is:
