using reverse proxy

[ploef]

Hi,

Did you try to get this container running behind an reverse proxy (apache or nginx). I just can't get this to work (keep getting 404's).

I found this on the tailon website but it is not working. Perhaps it is because it;s running inside docker container?

location /tailon/ws {
proxy_pass http://localhost:8888/tailon/ws;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}

location /tailon {
  proxy_pass http://localhost:8888;
}

Regards,
Peter

It appears to work like this:
default.conf

server {
    listen       8084;
    server_name  sago_proxy;

location / {
  proxy_pass      http://localhost:8080;
  proxy_redirect  http://localhost:8080/ /;
  proxy_read_timeout 60s;

  # May not need or want to set Host. Should default to the above hostname.
  proxy_set_header          Host            $host;
  proxy_set_header          X-Real-IP       $remote_addr;
  proxy_set_header          X-Forwarded-For $proxy_add_x_forwarded_for;
}

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

Running tailon:
docker run -it -v /var/log:/data --user=1000 -p 8080:8080 sago007/docker_tailon

Running nginx:
docker run -it --rm -v /ABSOLUTE/PATH/TO/FOLDER/WITH/DEFAULT.CONF:/etc/nginx/conf.d --net host -t nginx:1.10

Can be accessed with http://localhost:8084/

If you want a subfolder you need a rewrite rule.
This default.conf:
default.conf

server {
    listen       8084;
    server_name  sago_proxy;

location /tailon/ {
  rewrite ^/tailon(/.*)$ $1 break;
  proxy_pass      http://localhost:8080;
  proxy_redirect  http://localhost:8080/ /;
  proxy_read_timeout 60s;

  # May not need or want to set Host. Should default to the above hostname.
  proxy_set_header          Host            $host;
  proxy_set_header          X-Real-IP       $remote_addr;
  proxy_set_header          X-Forwarded-For $proxy_add_x_forwarded_for;
}

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

Means that http://localhost:8084/tailon/ works.

In your case you properly need a rule like:
rewrite ^/tailon/ws(/.*)$ $1 break;

Thanks! I'm going to give it a try and will let you know how it worked out.

This is almost working. I tries both rewrite rules. The first one doesn't work with the second one I only
got one 404 left:

GET http://sago_proxy/logs/ws/info?t=1467136255761 404 (Not Found)

server {

listen 80;
server_name sago_proxy;

location /logs/ {
  #rewrite ^/logs(/.*)$ $1 break;
  rewrite ^/logs/ws(/.*)$ $1 break;
  proxy_pass      http://localhost:8888;
  proxy_redirect  http://localhost:8888/ /;
  proxy_read_timeout 60s;

# May not need or want to set Host. Should default to the above hostname.
  proxy_set_header          Host            $host;
  proxy_set_header          X-Real-IP       $remote_addr;
  proxy_set_header          X-Forwarded-For $proxy_add_x_forwarded_for;
}

}

It should be noticed that you can also start with a different mount dir like this:
docker run -it -v /var/log:/data --user=1000 -p 8080:8080 sago007/docker_tailon /tailon/run.sh -r '/tailon/'
That way you can add the same arguments as in the example and you can avoid the rewrite rules.

I would not normally recommend this road as I believe the proxy should hide these details but it is an option.
