uninitialized constant ActiveSupport::XmlMini::IsolatedExecutionState

Bug report

krane blows up on deploy since last night. Possibly related to Rails 7.0.0 release? See similar: https://github.com/rails/rails/issues/43889

-> Need to require top level active_support in krane too? I'm not too familiar with Ruby or gem myself.

Expected behavior: krane doesnt blow up

Actual behavior: krane blows up

Version(s) affected: Both 2.3.0 & 2.3.4 are affected.

Steps to Reproduce

Run krane deploy:

$ krane deploy ${NAMESPACE} ${KUBE_CONTEXT} -f ./k8s/overlays/${ENVIRONMENT}/kustomized/${ENVIRONMENT}.yml --global-timeout=${KRANE_GLOBAL_TIMEOUT} ${KRANE_EXTRA_ARGS}

We worked around this issue by explicitly installing older activesupport before krane in our dockerfiles:

...
    gem install activesupport -v 6.1.4.3 && \
    gem install krane:2.3.4

Seems to work fine as a workaround, dunno if there are any fun side-effects.

The blew up our updates as well. I consider it a critical issue because it breaks clean installs of krane.

I just want to voice my support for this. It broke our deployments after update of shipit-engine. krane is not usable with activesupport 7.

Isn't https://github.com/Shopify/krane/pull/861 fixing this?

[benlangfeld]

@simi Indeed. Y'all just need to upgrade krane. This issue can be closed.
