A dynamic build badge server that uses the Buildkite Builds API and shields.io to turn any of your build meta-data values into a readme badge. Embed your code coverage, build timings, latest commit running on production, or anything you like!

For example, say you had the following code snippet somewhere in your my-org/my-pipeline build pipeline:

buildkite-agent meta-data set coverage '95%'

To show the value from the last passing master build, you’d:

<img src="https://my-app.heroku.com/my-org/my-pipeline/coverage?label=Coverage" alt="Coverage">

which would look like:

Available parameters:

• branch - the branch to find the latest build from. Default is master.
• state - the required state of the latest build on the branch. Default is passed.
• label - the label for the badge. Default is meta-data key name.
• color - any valid SVG named color or hex value (e.g. red or ff0033). Default is green.
• style - shields.io style (e.g. flat-square)
• logo - shields.io logo (e.g. data:image/png;base64,…)
• logoWidth - shields.io logoWidth (e.g. 40)

1. Create an API token
   Create a Buildkite API Token with read_builds access so it can fetch the latest build and grab its meta-data. Copy the API key and paste it into the next step…

3. Embeddinate your badges 🎉

You can also run this via Docker using buildkite/dynamic-build-badges:

docker run -p 8080:8080 -e BUILDKITE_API_KEY=xyz buildkite/dynamic-build-badges

• Ability to specify a range parameter, and have the color change from red → green depending on the value
• Speed up badge display by removing 302 and serving it directly with shields

• git clone
• env BUILDKITE_API_KEY=xxx npm run web
