Helm chart multi-tenancy configuration

caution

Multi-tenancy is currently only available for Camunda 8 Self-Managed with authentication enabled through Identity.

To configure multi-tenancy you must enable the multi-tenancy flag either in the Helm charts or via environment variables.

When using Helm charts, you can enable multi-tenancy globally with the flag global.multitenancy.enabled. Visit the Helm chart configuration for additional details.

danger

Disabling multi-tenancy can lead to unexpected behavior if previously enabled with active tenants

Troubleshooting​

Zeebe is unable to retrieve jobs for a tenant, unable to assign a task to yourself, or Operate retry is not functioning​

If multi-tenancy is enabled, you may encounter the following issues:

  • Zeebe is unable to retrieve jobs for a tenant when canceling or retrying via Operate or Tasklist.
  • You see the error Task could not be assigned - Service is not reachable when attempting to assign a task to yourself in Tasklist.
  • Retry operations in Operate do not function as expected.

These issues typically occur because the Zeebe client used by Operate and Tasklist does not have access to the required tenant(s). This access must be explicitly granted.

How to fix it​

You can resolve these issues by ensuring the Zeebe application is assigned to the tenant where the task or job resides. To do this:

  1. Log in to Camunda Identity.
  2. In the left-hand menu, go to Tenants.
  3. Click on the tenant that is experiencing the issue.
  4. Navigate to the Applications tab.
  5. Ensure that the checkbox for Zeebe is selected.
  6. Click Save if any changes were made.

Once the Zeebe application is assigned to the tenant, you should be able to:

  • Assign tasks to yourself in Tasklist.
  • Successfully retry jobs in Operate.
  • Retrieve jobs from the correct tenant context.
