[Bug] Cannot create more than one offer #1040

Closed Zvirovyi closed 2 months ago

Zvirovyi commented 3 months ago

When i do model.create_offer multiple times, i get exception:

kubernetes.client.exceptions.ApiException: (0)
Reason: [Errno 2] No such file or directory

Code example:

@pytest.mark.group(1)
@pytest.mark.abort_on_fail
async def test_cos(ops_test: OpsTest):
    await ops_test.model.deploy(
        "cos-lite",
        trust=True,
    )
    await ops_test.model.create_offer("grafana:grafana-dashboard", "grafana-dashboards") // this executes successfully
    await ops_test.model.create_offer("loki:logging", "loki-logging") // and this causes error
    await ops_test.model.create_offer("prometheus:receive-remote-write", "prometheus-receive-remote-write")
