Prerequisites
The following are prerequisites to use Azure DevOps extension.
Conjur setup
Conjur (OSS or Enterprise or Cloud) and the Conjur CLI are installed in the environment and running in the background.
This section describes how to set up the API Authentication for Conjur OSS or Enterprise
- Define the API Authentication policy
- Create a policy that defines the API Authentication, for example BotApp.
- !policy
id: BotApp
body:
# Define a human user, a non-human identity that represents an application, and a secret
- !user Dave
- !host myDemoApp
- &variables
- !variable secretVar
- !variable some-other-secret
- !permit
# Give permissions to the human user to update the secret and fetch the secret.
role: !user Dave
privileges: [read, update, execute]
resource: *variables
- !permit
# Give permissions to the non-human identity to fetch the secret.
role: !host myDemoApp
privileges: [read, execute]
resource: *variables
- Save the policy as BotApp.yml, and load it to root:
conjur policy load -b root -f /path/to/file/authn-iam.yml
Set the secret
a. Generate a secret
Generate a value for your application’s secret:
secretVal=$(openssl rand -hex 12 | tr -d '\r\n')
This generates a 12-hex-character value.
b. Store the secret
Store the generated value in Conjur:
conjur variable set -i BotApp/secretVar -v ${secretVal}
A policy predefined variable named BotApp/secretVar is set with a random
generated secret.
This section describes how to set up the API Authentication for Conjur Cloud
Pre-requisite:
- Conjur cloud
- Pcloud
- Conjur cloud cli
Refer the tutorial for Conjur Cloud Setup
- Manage Conjur Cloud users
- Set up the Conjur Cloud CLI
- Log in to Conjur Cloud
- Sync Privilege Cloud Safe to Conjur
To create a simple host that authenticates using an API key:
Create a policy for the host:
- !host
id: <host name>
annotations:
authn/api-key: true
Save the policy as myapp-host.yaml.
Load the policy file into the data policy branch:
conjur policy load -b data -f myapp-host.yaml
To grant permissions on secrets:
- !grant
role: !group delegation/consumers
member: !host /data/myapp
Save the file as grant_permissions.yml.
Load the policy to data/vault/secrets-safe:
conjur policy load -b data/vault/secrets-safe -f grant_permissions.yml
This section describes how to set up JWT Authentication for Conjur Cloud
To create a policy using JWT for conjur cloud, certain attributes are needed which can be taken from Access Token
Sample Access Token Microsoft Entra ID:
{
"typ":"JWT",
"alg":"RS256",
"x5t":"YTceO5IJyyqR6jzDS5iAbpe42Jw",

Conjur OSS and Enterprise JWT Authentication
- Define the JWT Authentication policy
- Create a policy that defines JWT Authentication auth-jwt.yml
- !policy
id: conjur/authn-jwt/azure
body:
- !webservice
#Mandatory variable: The JWT provider URI
#Uncomment either 'provider-uri' OR 'jwks-uri'
#- !variable
# id: provider-uri
- !variable
id: jwks-uri
#Optional variables
#Uncomment one or all of the following optional variables.
#Note: If you uncomment 'token-app-property' you must also uncomment 'identity-path',
#and vice versa;
- !variable
id: token-app-property
- !variable
id: identity-path
- !variable
id: issuer
#Group of applications that can authenticate using this JWT Authenticator
