## Skoala 0.40.x Upgrade Notes

### Affected Versions

You may be affected if you upgrade from any version to 0.40.x.

### Impact

The 0.40.x version includes updates to related Custom Resource Definitions (CRDs).
Since the custom resources in the `crds` directory of the skoala-init Chart do not automatically update
with installation, the updated CRD for this release is the gateway-api CRD, and the BackendTLSPolicy
upgrade requires manual intervention. Due to compatibility issues within the community regarding this update,
[refer to the relevant issue on kubernetes-sigs](https://github.com/kubernetes-sigs/gateway-api/issues/3086).

### Steps to upgrade

Please follow these steps to manually update the gateway CRD files that need upgrading:

1. Delete BackendTLSPolicy:

    ```shell
    kubectl delete crds `kubectl get crds | grep -E "backendtlspolicies.gateway.networking.k8s.io"`
    ```

2. Manually update the gateway-related CRD files:

    ```shell
    # CRD related to projectcontour
    kubectl apply -f skoala-init/charts/contour-provisioner/crds/contour.yaml
    # CRD related to gateway-api
    kubectl apply -f skoala-init/charts/contour-provisioner-prereq/crds/gateway-api.yaml
    ```

    and earlier. This is due to changes in the open-source component repository address
    related to the gateway. To ensure a smooth upgrade process, make sure to manually
    delete the old `gateway-api-admission-xxxxx` Job before proceeding with the update.

!!! note "Important Note"

    When the Microservice Engine version is greater than `v0.24.2`, there are incompatible updates
    for versions `v0.24.2` and earlier. Since the gateway involves changes in the open-source component
    repository addresses, it is necessary to manually delete the old `gateway-api-admission-xxxxx` Job
    before performing the upgrade. Then proceed with the normal upgrade process.

## 2023-08-03

!!! note "Important Note"

    Starting from Microservice Engine version `v0.24.2`, there is an incompatible update for versions `v0.24.2` and earlier. This is because the gateway involves a change in the address of the open-source component repository. Therefore, before updating, you need to manually delete the existing `gateway-api-admission-xxxxx` Job and then proceed with the normal upgrade process.
