Setting Secrets

reading time 3 minutes

You can easily use the Doppler CLI to create and update secret values.

Setting

The doppler secrets set command allows you to set one or more secrets at a time:

doppler secrets set KEY1="123"
doppler secrets set KEY1="123" KEY2="456"

You can also set the value of a secret to be a file:

doppler secrets set SSH_KEY="$(cat ./id_rsa)"

By default, the CLI will output the key and values on completion which is useful for confirming the value was set as expected.

However, if setting secrets using a script, you'll want prevent this output by using the --silent flag:

doppler secrets set KEY1="123" --silent

Uploading

When starting out with Doppler, you've likely got an existing app config file (e.g. .env or config.json) and you can use the doppler secrets upload command to populate the secrets for a new project without leaving the terminal.

# ENV and JSON formats supported
doppler secrets upload sample.env
doppler secrets upload secrets.json

Now you know how to set secrets using the Doppler CLI.
