kubectl in the docker container is not able to communicate to kind cluster.

What you expected to happen:

It is expected to run ct install in docker container with k8s cluster on the host machine.

How to reproduce it:

• kind create cluster
• checkout to the charts repo with ct.yaml
• docker run -it --workdir=/data --volume ~/.kube/config:/root/.kube/config:ro --volume $(pwd):/data quay.io/helmpack/chart-testing:v3.5.0 ct install
