### Controller (running locally)

1. Set env $WATCH_NAMESPACE (default value is "istio-system") and $LEADER_ELECTION_NAMESPACE (default value is "istio-operator")

1. Create the `WATCH_NAMESPACE` and `LEADER_ELECTION_NAMESPACE` if they are not created yet.

```bash
kubectl create ns $WATCH_NAMESPACE --dry-run -o yaml | kubectl apply -f -

                    null,
                    type.isIncludesDependencies(),
                    type.getLanguage().id(),
                    type.getPathTypes().contains(JavaPathType.CLASSES));
            // TODO: watch out for module path
        });

        // Note: here, type decides is artifact added to "build path" (for example during resolution)

# if there is a change in requirements.in then all lock files will be updated
# accordingly.

# -e: abort script if one command fails
# -u: error if undefined variable used
# -o pipefail: entire command fails if pipe fails. watch out for yes | ...
# -o history: record shell history
set -euo pipefail -o history

# Check for required arguments
if [ -z "$1" ]; then
  echo "Usage: $0 <path_to_tensorflow_wheel> <python_version>"
  exit 1

- Kube-apiserver: Fixed a `1.27`+ regression in watch stability by serving watch requests without a `resourceVersion` from the watch cache by default, as in <`1.27` (disabling the change in PR 115096 by default). This mitigates the impact of an etcd watch bug (https://github.com/etcd-io/etcd/pull/17555). If the 1.27 change in PR 115096 to serve these requests from underlying storage is still desired despite the impact on watch stability, it can be re-enabled with a `WatchFromStorageWi...

# Controllers

Istio has a variety of [controllers](https://kubernetes.io/docs/concepts/architecture/controller/), which basically watch some inputs and do something.
This can be reading from Kubernetes and writing other objects back, writing to proxies over XDS, etc.

Unfortunately, writing controllers is very error prone, even for seemingly simple cases.
To work around this, Istio has a variety of abstractions meant to make writing controllers easier.
