Cluster Secrets Buildkite Plugin

A Buildkite plugin used to fetch secrets from Buildkite Secrets,

Storing Secrets

There are two options for storing and fetching secrets.

You can create a secret in your Buildkite cluster(s) from the Buildkite UI following the instructions in the documentation here.

One at a time

Create a Buildkite secret for each variable that you need to store. Paste the value of the secret into buildkite.com directly.

A pipeline.yml like this will read each secret out into a ENV variable:

steps:
  - command: echo "The content of ANIMAL is \$ANIMAL"
    plugins:
      - cluster-secrets#v1.0.0:
          variables:
            ANIMAL: llamas
            FOO: bar

Multiple

Create a single Buildkite secret with one variable per line, encoded as base64 for storage.

For example, setting three variables looks like this in a file:

Foo=bar
SECRET_KEY=llamas
COFFEE=more

Then encode the file:

cat data.txt | base64

Next, upload the base64 encoded data to buildkite.com in your browser with a key of your choosing - like llamas. The three secrets can be read into the job environment using a pipeline.yml like this:

steps:
  - command: build.sh
    plugins:
      - cluster-secrets#v1.0.0:
          env: "llamas"
