i've an nginx container, on port 9200, that acts as load balancer. This is config file:
proxy_ignore_headers Set-Cookie; add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Headers' 'Range'; upstream backend { server 192.168.99.103:9500 weight=3; server 192.168.99.104:9500; server 192.168.99.105:9500; } server { listen 80; server_name 172.17.0.1; location = /LynyrdSkynyrdFreebirdAudio.mp4 { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Headers' 'Range'; if ($request_method = OPTIONS ) { add_header Access-Control-Allow-Methods "GET, OPTIONS"; add_header Content-Length 0; add_header Content-Type text/plain; return 200; } proxy_pass http://backend/; add_header X-Upstream $upstream_addr; } location = /LynyrdSkynyrdFreebirdVideo.mp4 { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Headers' 'Range'; if ($request_method = OPTIONS ) { add_header Access-Control-Allow-Methods "GET, OPTIONS"; add_header Content-Length 0; add_header Content-Type text/plain; return 200; } proxy_pass http://backend; add_header X-Upstream $upstream_addr; } } This container load balance requests in the following way: when arrives a request localhost:9200/LynyrdSkynyrdFreebirdVideo.mp4 or localhost:9200/LynyrdSkynyrdFreebirdAudio.mp4, it balances requests across 3 servers. These 3 servers are 3 nginx containers that acts as cache. This is config file of nginx caches:
proxy_cache_path /tmp/nginx levels=1:2 keys_zone=my_zone:10m inactive=60m; proxy_cache_key "$scheme$request_method$host$request_uri"; proxy_cache_methods GET HEAD POST; proxy_cache_valid 200 206 100m; proxy_ignore_headers Set-Cookie; add_header 'Access-Control-Allow-Origin' '*' always; add_header 'Access-Control-Allow-Headers' 'Range'; server { listen 80; server_name 172.17.0.1; #charset koi8-r; #access_log /var/log/nginx/log/host.access.log main; location / { } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} location /demo/ { proxy_cache my_zone; add_header X-Proxy-Cache $upstream_cache_status; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_pass http://172.17.0.1:8700/shaka-player-master/demo/index1.html ; } location /media { proxy_cache my_zone; add_header X-Proxy-Cache $upstream_cache_status; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_pass http://172.17.0.1:8700/shaka-player-master/media/example-av.mpd ; } location = /example-av1.mpd { add_header 'Access-Control-Allow-Origin' '*'; proxy_cache my_zone; add_header X-Proxy-Cache $upstream_cache_status; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_pass http://192.168.99.103:9600/shaka-player/media/example-av1.mpd; } location = /LynyrdSkynyrdFreebirdVideo.mp4 { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Headers' 'Range'; proxy_cache my_zone; add_header X-Proxy-Cache $upstream_cache_status; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_pass http://192.168.99.103:9600/shaka-player/media/LynyrdSkynyrdFreebirdVideo.mp4 ; } location = /LynyrdSkynyrdFreebirdAudio.mp4 { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Headers' 'Range'; proxy_cache my_zone; add_header X-Proxy-Cache $upstream_cache_status; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_pass http://192.168.99.103:9600/shaka-player/media/LynyrdSkynyrdFreebirdAudio.mp4; } } If i point to load balancer, i.e. localhost:9200/LynyrdSkynyrdFreebirdVideo.mp4 or localhost:9200/LynyrdSkynyrdFreebirdAudio.mp4, there is 404 not found. I expect that, if i point to this URL, load balancer balances request to 192.168.99.103(or 104, or 105):9500/LynyrdSkynyrdFreebirdVideo.mp4 or 192.168.99.103(or 104, or 105):9500/LynyrdSkynyrdFreebirdAudio.mp4. But in the upstream block i don't know if in server directive i can add a path.
In fact, this is, i think, the very problem: in fact, if i point to 192.168.99.103(or104, or105):9500/LynyrdSkynyrdFreebirdAudio(or Video).mp4, i get the content correctly.
