Create a Service Account in Keycloak

Set up a Keycloak service account using the Keycloak administration console or the Keycloak REST API. A service account can be used to get a long-lived token that is used by automation tools.

In Keycloak, service accounts are associated with a client. See Service Accounts for more information from the Keycloak documentation.

Procedure

Follow the steps in only one of the following sections, depending on if it is preferred to use the Keycloak REST API or the Keycloak administration console UI.

Log in to the administration console.

See Access the Keycloak User Management UI for more information.
Click Clients under the Manage header of the navigation panel on the left side of the page.

  The Client Protocol must be openid-connect and the Root URL can be left blank.

3. Click on Add mapper then on By configuration.
4. Change the Mapper Type to Hardcoded Role.

9. Click on the role called shasta admin.
10. Click the Assign button.

Use the Keycloak REST API

(ncn-mw#) Create the get_master_token function to get a token as a Keycloak master administrator.

MASTER_USERNAME=$(kubectl get secret -n services keycloak-master-admin-auth -ojsonpath='{.data.user}' | base64 -d)
MASTER_PASSWORD=$(kubectl get secret -n services keycloak-master-admin-auth -ojsonpath='{.data.password}' | base64 -d)
SITE_DOMAIN="$(craysys metadata get site-domain)"
SYSTEM_NAME="$(craysys metadata get system-name)"
AUTH_FQDN="auth.cmn.${SYSTEM_NAME}.${SITE_DOMAIN}"

function get_master_token {
  curl -ks -d client_id=admin-cli -d username="${MASTER_USERNAME}" --data-urlencode password="${MASTER_PASSWORD}" \
      -d grant_type=password "https://${AUTH_FQDN}/keycloak/realms/master/protocol/openid-connect/token" | \
  jq -r .access_token
}

(ncn-mw#) Create the client by doing a POST call for a JSON object.

The clientId should be changed to the name for the new service account.

curl -is -H "Authorization: Bearer $(get_master_token)" -H "Content-Type: application/json" -d '
{
  "clientId": "my-test-client",
  "standardFlowEnabled": false,
  "implicitFlowEnabled": false,
  "directAccessGrantsEnabled": false,
  "serviceAccountsEnabled": true,
  "publicClient": false,
  "protocolMappers": [
    {
      "name": "admin-role",
      "protocol": "openid-connect",
      "protocolMapper": "oidc-hardcoded-role-mapper",
      "consentRequired": false,
      "config": {
        "role": "shasta.admin"
      }
    }
  ]
}
' \
"https://${AUTH_FQDN}/keycloak/admin/realms/shasta/clients"

Output similar to the following is expected:

HTTP/2 201
location: https://auth.cmn.system1.us.cray.com/keycloak/admin/realms/shasta/clients/bd8084d2-08bf-45cb-ab94-ee81e39921be
