What happened:

As soon as there is a DeployItem for the container deployer, the container deployer enters a loop of reconcile events. Even after the DeployItem has been successfully processed and the corresponding Pod has gone, there are lots of log entries like this:

   {
        "level": "info",
        "ts": "2023-07-28T13:46:38.735Z",
        "logger": "deployer.container.podReconciler",
        "msg": "history: deployitem update",
        "reconciledResource": {
            "name": "container-1-container-deployer-2n7lc",
            "namespace": "example"
        },

    },
    {

        "ts": "2023-07-28T13:46:39.668Z",
        "logger": "deployer.container",

How to reproduce it (as minimally and precisely as possible):

Deploy an Installation with a container DeployItem, for example test/integration/testdata/container-deployer/installation-1.

Anything else we need to know?:

The PodReconciler does not only get events from the PodEventHandler, but also regularly watches DeployItems. Therefore, it receives all events itself, which it triggers for the container deployer. This results in a loop of events.

Probably, the issue occurs only if the landscaper host and resource cluster are the same. If these are different clusters, the PodReconciler would watch the host cluster, whereas the DeployItems are on the resource cluster. (But I did not verify this.)

Environment:

• Landscaper version: v0.73.0
• Kubernetes version (use kubectl version):
• Others:
