Script for fetching images is failing for net-istio

[kimwnasptd]

Bug Description

The script for fetching the knative images is failing because of a missing net-istio.yaml, according to the printed logs.

We need to ensure the script is able to gather all the images from Knative, as it's needed for scanning canonical/bundle-kubeflow#1029 and airgapped efforts.

For more context on how the image gathering script is working take a look in #142 (comment)

To Reproduce

./tools/get-images.sh

Environment

main and track/1.12 branches

Relevant Log Output

Error: open ./net-istio.yaml: no such file or directory

Additional Context

The script should also have a set -xe to ensure it stops on the first failure

In the end the issue is because the version that gets requested net-istio, which will be the same as Knative Serving, does not exist and thus the script fails to download it.

knative-operators/tools/get-images.sh

Line 35 in 484077a

NET_ISTIO_VERSION="${KNATIVE_SERVING_VERSION}"

Note that it's also a bug that this failed, yet the script succeeded and why we should set set -e to our bash scripts
canonical/bundle-kubeflow#1030

While not directly related to this issue, in the future we'll need to update the tests to not download upstream yamls and find images but instead parse the images used by the charms
