As a result, pushing a large object ## with Git (i.e. a single large file) can lead to a 411 error. In theory you can get ## around this by tweaking this configuration file and either: ## - installing an old version of Nginx with the chunkin module [2] compiled in, or ## - using a newer version of Nginx. ## ## At the time of writing we do not know if either of these theoretical solutions works. ## As a workaround users can use Git over SSH to push large files. ## ## [0] https://git.kernel.org/cgit/git/git.git/tree/Documentation/technical/http-protocol.txt#n99 ## [1] https://github.com/agentzh/chunkin-nginx-module#status ## [2] https://github.com/agentzh/chunkin-nginx-module ## ## ################################### ## SSL configuration ## ################################### ## ## See installation.md#using-https for additional HTTPS configuration details. upstream gitlab { server unix:/home/git/gitlab/tmp/sockets/gitlab.socket fail_timeout=0; } ## Normal HTTP host server { listen 0.0.0.0:80; listen [::]:80 default_server; server_name YOUR_SERVER_FQDN; ## Replace this with something like gitlab.example.com server_tokens off; ## Don't show the nginx version number, a security best practice ## Redirects all traffic to the HTTPS host root /nowhere; ## root doesn't have to be a valid path since we are redirecting rewrite ^ https://$server_name$request_uri? permanent; } ## HTTPS host server { listen 0.0.0.0:443 ssl; listen [::]:443 ssl default_server; server_name YOUR_SERVER_FQDN; ## Replace this with something like gitlab.example.com server_tokens off; root /home/git/gitlab/public; ## Increase this if you want to upload large attachments ## Or if you want to accept large git objects over http client_max_body_size 20m; ## Strong SSL Security ## https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html & https://cipherli.st/ ssl on; ssl_certificate /etc/nginx/ssl/gitlab.crt; ssl_certificate_key /etc/nginx/ssl/gitlab.key; # GitLab needs backwards compatible ciphers to retain compatibility with Java IDEs ssl_ciphers "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4"; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:10m; ## [WARNING] The following header states that the browser should only communicate ## with your server over a secure connection for the next 24 months. add_header Strict-Transport-Security max-age=63072000; add_header X-Frame-Options SAMEORIGIN; add_header X-Content-Type-Options nosniff; ## [Optional] If your certficate has OCSP, enable OCSP stapling to reduce the overhead and latency of running SSL. ## Replace with your ssl_trusted_certificate.
