#Cloud Foundry Static Buildpack
Working on a pure front-end only web app or demo? It is easy to share it via your Cloud Foundry:
cf push my-site -m 64M -b https://github.com/cloudfoundry/staticfile-buildpack.git
Your Cloud Foundry might already have this buildpack installed (see Upload section for administration):
$ cf buildpacks
Getting buildpacks...
buildpack position enabled locked filename
staticfiles 1 true false staticfile-buildpack-v0.4.2.zip
java_buildpack 2 true false java-buildpack-offline-v2.4.zip
...
You only need to create a Staticfile
file for Cloud Foundry to detect this buildpack:
touch Staticfile
cf push my-site -m 64M
Why -m 64M
? Your static assets will be served by Nginx and it only requires 20M [reference]. The -m 64M
reduces the RAM allocation from the default 1G allocated to Cloud Foundry containers. In the future there may be a way for a buildpack to indicate its default RAM requirements; but not as of writing.
By default, the buildpack will serve index.html
and all other assets from the root folder of your project.
In many cases, you may have an alternate folder where your HTML/CSS/JavaScript files are to be served from, such as dist/
or public/
.
To configure the buildpack add the following line to your Staticfile
:
root: dist
Protect your website with a user/password configured via environment variables.
Convert the username / password to the required format: http://www.htaccesstools.com/htpasswd-generator/
For example, username bob
and password bob
becomes bob:$apr1$DuUQEQp8$ZccZCHQElNSjrg.erwSFC0
.
Create a file in the root of your application Staticfile.auth
. This becomes the .htpasswd
file for nginx to project your site. It can include one or more user/password lines.
bob:$apr1$DuUQEQp8$ZccZCHQElNSjrg.erwSFC0
Push your application to apply changes to basic auth. Remove the file and push to disable basic auth.
If your site doesn't have a nice index.html
, you can configure Staticfile
to display a Directory Index of other files; rather than show a relatively unhelpful 404 error.
Add a line to your Staticfile
that begins with directory:
directory: visible
You can customise the Nginx configuration further, by adding nginx.conf
and/or mime.types
to your root folder.
If the buildpack detects either of these files, they will be used in place of the built-in versions. See the default nginx.conf and mime.types files for inspiration.
Everyone can automatically use this buildpack if your Cloud Foundry Administrator uploads it.
Releases are publicly downloadable.
To initially install, say v0.5.1:
wget https://github.com/cloudfoundry/staticfile-buildpack/releases/download/v0.5.1/staticfile-buildpack-v0.5.1.zip
cf create-buildpack staticfiles_buildpack staticfile-buildpack-v0.5.1.zip 1
Subsequently update the buildpack, say v0.9.9:
wget https://github.com/cloudfoundry/staticfile-buildpack/releases/download/v0.9.9/staticfile-buildpackv0.9.9.zip
cf update-buildpack staticfiles_buildpack -p staticfile-buildpackv0.9.9.zip
- Update git submodules
git submodule update --init --recursive
- Get latest buildpack dependencies
BUNDLE_GEMFILE=cf.Gemfile bundle
- Build the buildpack
BUNDLE_GEMFILE=cf.Gemfile bundle exec buildpack-packager [ --cached | --uncached ]
- Use in Cloud Foundry
Upload the buildpack to your Cloud Foundry and optionally specify it by name
cf create-buildpack custom_node_buildpack node_buildpack-offline-custom.zip 1
cf push my_app -b custom_node_buildpack
Buildpacks use the Machete framework for running integration tests.
To test a buildpack, run the following command from the buildpack's directory:
BUNDLE_GEMFILE=cf.Gemfile bundle exec buildpack-build
More options can be found on Machete's Github page.

This buildpack is based heavily upon Jordon Bedwell's Heroku buildpack and the modifications by David Laing for Cloud Foundry nginx-buildpack. It has been tuned for usability (configurable with Staticfile
) and to be included as a default buildpack (detects Staticfile
rather than the presence of an index.html
). Thanks for the buildpack Jordon!
