        with:
          url: ${{ secrets.CONJUR_URL }}
          account: cyberarkdemo
          authn_id: ${{ secrets.CONJUR_AUTHN_ID }}
          secrets: db/sqlusername|sql_username;db/sql_password
      # ...

Conjur Setup

JWT Authenticator is required at Conjur server. You may wish to refer to official doc

The sample policy below validates GitHub repository & workflow

1. Sample authenticator policy
2. Sample app id policy
3. Sample secret values and commands:

conjur policy load -f ./policy/github-authn-jwt.yml -b root
conjur policy load -f ./policy/github-app-id.yml -b root

conjur variable set -i conjur/authn-jwt/github/issuer -v "https://token.actions.githubusercontent.com"
conjur variable set -i conjur/authn-jwt/github/jwks-uri -v "https://token.actions.githubusercontent.com/.well-known/jwks"
conjur variable set -i conjur/authn-jwt/github/token-app-property -v "workflow"
conjur variable set -i conjur/authn-jwt/github/enforced-claims -v "workflow,repository"
conjur variable set -i conjur/authn-jwt/github/identity-path -v "/github-apps"

Arguments

Required

• url - this is the path to your Conjur instance endpoint. e.g. https://conjur.cyberark.com:8443
• account - this is the account configured for the Conjur instance during deployment.
• authn_id - this is the ID of Authn-JWT at Conjur
• secrets - a semi-colon delimited list of secrets to fetch. Refer to Secrets Syntax in the README below for more details.

Optional

• certificate - if using a self-signed certificate, provide the contents for validated SSL.

Not required

• host_id - this is the Host ID granted to your application by Conjur when created via policy. e.g. host/db/github_action
• api_key - this is the API key associated with your Host ID declared previously.

Secrets Syntax

{{ conjurVariable1|envVarName1;conjurVariable2 }}

The secrets argument is a semi-colon (;) delimited list of secrets. Spaces are NOT SUPPORTED. The list can optionally contain the name to set for the environment variable.

Example

db/sqlusername|sql_username;db/sql_password

In the above example, the first secret section is db/sqlusername|sql_username. The | separates the Conjur Variable ID from the environment variable that will contain the value of the Conjur Variable's value.

The second secret section is db/sql_password. When no name is given for the environment variable, the Conjur Variable Name will be used. In this example, the value would be set to SQL_PASSWORD as the environment variable name.

Security

Protecting Arguments

It is recommended to set the URL, Host ID, and API Key values for the Action to function as secrets by going to Settings > Secrets in your GitHub repository and adding them there. These can then be called in your workflows' YAML file as a variable: ${{ secrets.SECRETNAME }}

Masking

The CyberArk Conjur Secret Fetcher GitHub Action utilizes masking prior to setting secret values to the environment. This prevents output to the console and to logs.
