Run 0.7.0 and 1.1.1 at the same time

[hendrikmaus]

I want to start the migration phase from v0.7.0 to v1+ by running both versions of the controller side-by-side in the same namespace. I used the community Helm chart's nameOverride to create a unique set of resources which can live next to the previous ones 👍🏻 however the v1 controller keeps reading the ConfigMap of the v0.7:

The v0.7 controller does not disocver the new ConfigMap.

Is there a way to explicitly tell the v1 controller which ConfigMap to use?

[ryota-sakamoto]

For now, there is no way to use any ConfigMap in the controller.

[hendrikmaus]

I reckon the only option is to run the two versions in two different namespaces?

[ryota-sakamoto]

yes, but I will take #77, so you will be able to use another ConfigMap name after implementing it.

[hendrikmaus]

👍🏻 I saw you self-assigned the issue, hence I'll not work on it.

[ryota-sakamoto]

#286 is merged, but not released yet.

[hendrikmaus]

Thank you, I will give it a spin.
