Cloud Foundry also supports running Docker containers. Setting up Datadog to monitor your Docker containers is done via the Dockerfile instead of a buildpack, as buildpacks are unsupported. This provides a mechanism to add the buildpack to the dockerfile.
The following example covers a simple flask app and provides more detail on how to get started.
This Dockerfile demonstrates setting up the Datadog assets, sample flask app, and an entrypoint file. As a note, the buildpack requires Python in order to work correctly.
To build your image, run the build.sh script. You can edit this script to customize the name of the resulting docker image.
Once the image is built, you need to push it to your Docker registry.
A simple flask application demonstrating examples on tracing, dogstatsd and logs. The requirements.txt file contains the dependencies.
The entrypoint file has the two Datadog scripts sourced, instead of them being run directly. By having them sourced, they aren't blocking on the main script.
The manifest file contains the minimal parameters required to push your docker app to your cloudfoundry: cf push -f manifest.yaml.
Be sure to configure your Datadog API key in the env section.
