chezmoi includes support for Doppler using the doppler CLI to expose data through the doppler and dopplerProjectJson template functions.


Doppler is in beta and chezmoi's interface to it may change. Note: Doppler only supports secrets in the UPPER_SNAKE_CASE format.

Log in using:

$ doppler login

It is now possible to interact with the doppler CLI in two different, but similar, ways. Both make use of the command doppler secrets download --json --no-file behind the scenes but present a different experience.

The doppler function is used in the following way:

{{ doppler "SECRET_NAME" "project name" "config" }}

All secrets from the specified project/config combination are cached for subsequent access and will not requery the doppler CLI for another secret in the same project/config. This caching mechanism enhances performance and reduces unnecessary CLI calls.

The dopplerProjectJson presents the secrets as json structured data and is used in the following way:

{{ (dopplerProjectJson "project" "config").PASSWORD }}

Additionally one can set the default values for the project and config (aka environment) in your config file, for example:

    project = "my-project"
    config = "dev"
With these default values, you can omit them in the call to both doppler and dopplerProjectJson, for example:
{{ doppler "SECRET_NAME" }}
{{ dopplerProjectJson.SECRET_NAME }}

It is important to note that neither of the above parse any individual secret as json. This can be achieved by using the fromJson function, for example:

{{ (doppler "SECRET_NAME" | fromJson).created_by.email_address }}
{{ (dopplerProjectJson.SECRET_NAME | fromJson).created_by.email_address }}
Obviously the secret would have to be saved in json format for this to work as expected.
