This topic describes how to configure the Staticfile buildpack and use it to push static content to the web. It also shows you how to serve a simple “Hello World” page using the Staticfile buildpack.
Note: BOSH configured custom trusted certificates are not supported by the Staticfile buildpack.
Staticfile buildpack: The buildpack that provides runtime support for staticfile apps and apps with backends hosted elsewhere. To find which version of NGINX the current Staticfile buildpack uses, see the Staticfile buildpack release notes.
Elastic Runtime requires a file named
Staticfile in the root directory of the app to use the Staticfile buildpack with the app.
NGINX requires 20 MB of RAM to serve static assets.
When using the Staticfile buildpack, we recommend pushing apps with the
-m 64M option to reduce RAM allocation from the default 1 GB allocated to containers by default.
Follow the procedure below to create and push a single page app using the Staticfile buildpack.
|1||Create and move into a root directory for the sample app in your workspace:
$ mkdir sample $ cd sample
$ echo 'Hello World' > index.html
|3|| Create an empty file named
$ touch Staticfile
|4|| Use the
For more information, see the Login section of the Getting Started with the cf CLI documentation.
$ cf login
|5|| Push the sample app:
$ cf push hello -m 64M
|6||Find the URL of the app in the output.
A fragment of output is shown below:
Creating app hello in org sample-org / space sample-space as firstname.lastname@example.org... OK … requested state: started instances: 1/1 usage: 64M x 1 instances urls: hello.example.com
|7||Navigate to the URL to see the sample app running.|
This section describes various ways you can configure the Staticfile buildpack options and how to push your Staticfile app.
This table describes some of the aspects of the Staticfile buildpack that you can configure.
|Alternative root||Allows you to specify a root directory other than the default, which is
|Directory list||An HTML page that displays a directory index for your site. A sample of a directory list is shown below.
If your site is missing an index.html, your app displays a directory list instead of the standard 404 error page.
|SSI||Server Side Includes (SSI) allows you to show the contents of files on a web page on the web server. For general information about SSI, see the Server Side Includes entry on Wikipedia.|
that look like
|GZip file serving and compressing||The gzip_static
and gunzip modules are enabled by default. This allows NGINX to serve files stored in compressed GZ format, and to uncompresses them for clients that do not support compressed content or responses.
You may want to disable compression in particular circumstances, for example if serving to very old browser clients.
|Basic authentication||Allows you to place simple access controls on your app.
|Proxy support||Allows you to use a proxy to download dependencies during staging.|
|Force HTTPS||A way to enforce that all requests are sent through HTTPS. This redirects non-HTTPS requests as HTTPS requests. For an example of when to avoid forcing HTTPS, see About FORCE_HTTPS with Reverse Proxies.|
|Dot Files||By default, hidden files (those starting with a
|HTTP Strict Transport Security||Causes NGINX to respond to all requests with the header
|Custom Location configuration||To customize the
|Custom NGINX configuration||Additional NGINX configuration can be applied, such as mapping file extensions to mime types. See the NGINX documentation for examples.|
In the root directory of your app, create an empty file named
$ touch Staticfile
