heroku-buildpack-nginx

This is the official dokku buildpack for static websites, powered by nginx.

Usage

All static files that you want to serve should be in the root directory of your repository. No need to use a separate www folder. buildpack-nginx will automatically download the buildpack, download NGINX, compile it, and install it. The next time you push your project, the buildpack will reuse the precompiled binaries.

Dokku

To trigger detection of this buildpack you need to add a dotfile:

Add an empty file called .static to your root directory of your web project (regardless if you use a custom value for NGINX_ROOT)

Heroku

Heroku users can use this buildpack by running the following command:

heroku buildpacks:set https://github.com/dokku/buildpack-nginx.git

Configuration

Custom nginx root

You can override the nginx root via setting the NGINX_ROOT environment variable. This should be a relative path in your repository.

# where the app is named `static-app`
# and the root dir is _site
dokku config:set static-app NGINX_ROOT=_site

Default to index for history routing

By default, this buildpack will 404 if a requested file is not found. For static sites that use the browser's history router to show the correct context, setting the NGINX_DEFAULT_REQUEST to a specific file will override this.

# where the app is named `static-app`
# and the desired default response is index.html
dokku config:set static-app NGINX_DEFAULT_REQUEST=index.html

Custom nginx directives

You can configure following nginx directives via environment variables.

NGINX_WORKERS : worker_processes directive
NGINX_WORKER_CONNECTIONS : worker_connections directive
NGINX_CLIENT_BODY_TIMEOUT : client_body_timeout directive
NGINX_CLIENT_MAX_BODY_SIZE : client_max_body_size directive (in MB)

# where the app is named `static-app`
dokku config:set static-app NGINX_WORKERS=4 \
                            NGINX_WORKER_CONNECTIONS=1024 \
                            NGINX_CLIENT_BODY_TIMEOUT=5 \
                            NGINX_CLIENT_MAX_BODY_SIZE=1

Custom nginx config file

You may completely override the built-in nginx config by placing an app-nginx.conf.sigil file in the root, modeled after our own conf/app-nginx.conf.sigil. This will be used inside of the container, and not by the host Dokku instance. See the sigil project for more information concerning the sigil format.

Custom MIME types

Files will be served with a Content-Type according to a list of supported MIME types at conf/mime.types. If you need to serve files of a MIME type not included in the list, you can provide your own mime.types file in the root.
