nginx reverse proxy folder 403 error - nginx

Question

I am running nginx as reverse proxy directly installed on the server. To access different webapps I am using sub folders. Two webapps are running in docker containers (pydio and cops).
For pydio this location commands are working; same one for cops is not working.
location ^~ /pydio {
client_max_body_size 20G;
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
send_timeout 300;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://127.0.0.1:82;
proxy_redirect off;
}
I tried different settings found by searching - none worked.
This is the latest version which results in a 403 error:
location ^~ /ebooks(.*)$ {
client_max_body_size 1G;
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
send_timeout 300;
rewrite ^/ebooks(/.*)$ $1 break;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://192.168.100.67:83$1/;
proxy_redirect off;
autoindex on;
}
And this entry in my error.log:
[error] 29235#29235: *1 directory index of "/var/www/ebooks/" is forbidden, client: 87.174.111.111, server: myadress.de, request: "GET /ebooks/ HTTP/1.1", host: "myadress.de"
When I hit 192.168.100.67:83 directly in my browser everything is working fine.
The folder /var/www/ebooks has www-data:www-data and 750 rights and it is linked with the container by the running command:
docker run ... -v /var/www/ebooks:/config ... according to this https://hub.docker.com/r/lsioarmhf/cops/
Hope I made my problem clear and you will help me. Thanks
good an bad news.
After testing a little more I found setting passing the command to docker correctly.
location ^~ /ebooks {
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
send_timeout 300;
rewrite ^/ebooks(/.*)$ $1 break;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_pass http://127.0.0.1:83$1;
proxy_redirect off;
}
But cops page is only displayed in a basic way (background color changes but matrix not shown)
This is error log entry:
an upstream response is buffered to a temporary file /var/lib/nginx/proxy/1/00/0000000001 while reading upstream, client: 11.114.211.38, server: myadress.de, request:: "GET /ebooks/resources/jQuery/jquery-1.11.1..js?v=1.0.1 HTTP/1.1", upstream: "http://127.0.0.1:83/resources/jQuery/jquery-1.11.1.min.js", host: "myadress.de", referrer: "https://myadress/ebooks/"
To give you a complete picture. This is nginx config of cops container.
server {
listen 80 default_server;
# listen 443 ssl;
server_name _;
# ssl_certificate /config/keys/cert.crt;
# ssl_certificate_key /config/keys/cert.key;
access_log /config/log/nginx/access_cops.log;
error_log /config/log/nginx/error_cops.log;
root /var/www/localhost/cops;
index index.php;
#Useful only for Kobo reader
location /cops/ {
rewrite ^/download/(\d+)/(\d+)/.*\.(.*)$ /fetch.php?data=$1&db=$2&type=$3 last;
rewrite ^/download/(\d+)/.*\.(.*)$ /fetch.php?data=$1&type=$2 last;
break;
}
#Can break loading the images - if you don't see anything, comment
location ~ ^/images.*\.(gif|png|ico|jpg)$ {
expires 31d;
}
#Can also break loading the images, comment if it happens
location ~ .(js|css|eot|svg|woff|ttf)$ {
expires 31d;
}
#Not necessarily correct, it depends on distro.
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass 127.0.0.1:9000;
}
location /books {
root /;
internal;
}
}
Any ideas if I am missing something?
