Docker copy fails with permission denied

[prary]

Running CLUSTER_TYPE=minikube MINIKUBE_PROFILE=ci MOLECULE_USE_DEV_IMAGES=true MOLECULE_SCENARIO="jaeger-test" make molecule-test
fails with following error.
'''
docker cp "/home/arya/.kube/config" molecule-volume-helper:/data/kubeconfig
ERRO[0000] Can't add file /home/arya/.kube/config to tar: open /home/arya/.kube/config: permission denied
'''

kiali/make/Makefile.molecule.mk

Line 149 in 2c22b05

$(DORP) cp "${MOLECULE_KUBECONFIG}" molecule-volume-helper:/data/kubeconfig

Temporary fix for me was to copy

cp .kube/config ~/config
docker cp config molecule-volume-helper:/data/kubeconfig

Looks like you just have a permissions restriction on your /home/arya/.kube/config file.

That's what I thought, have tried with chmod+777 but it fails with same error. Not sure why?

Moving this to "Discussions" - doesn't seem to be an issue with anything in Kiali

sudo addgroup --system docker
sudo adduser $USER docker
newgrp docker
sudo snap disable docker
sudo snap enable docker

you can try it and see docker work normal, i think it's snap design error
