Description

In attempting to use the minikube image build command on a local dockerfile I am seeing the following:

$ minikube image build .
error checking context: 'no permission to read from '/var/lib/minikube/build/build.87560460/Dockerfile''.

This is the dockerfile I am trying to build (from skaffold/examples/microservices/base/Dockerfile):

$ cat Dockerfile 
FROM gcr.io/distroless/base
# Define GOTRACEBACK to mark this container as using the Go language runtime
# for `skaffold debug` (https://skaffold.dev/docs/workflows/debug/).
ENV GOTRACEBACK=single
CMD ["./app"]

os: linux (debian-rodete) minikube_version: v1.23.2

$ minikube version

This occurs for me when using using both docker and KVM virtualization (--vm-driver=docker & --vm-driver=kvm2)

NOTE: My linux user id is in both kvm and libvirt groups and the kvm2 driver is working properly:

$ sudo virsh net-list --all
 Name          State    Autostart   Persistent
------------------------------------------------
 default       active   yes         yes
 mk-minikube   active   yes         yes

Any idea why I might be seeing this permission denied issue? Am I perhaps using minikube image build . incorrectly with my current env/vm-driver setup? I can see the directory referenced in the permission denied error - /var/lib/minikube/build/build.87560460/Dockerfile in the minikube vm (below output from --vm-driver=kvm2) but not the Dockerfile:

$ minikube ssh
...
$ pwd
/var/lib/minikube/build
$ ls
build.2571535838  build.2571535838.tar

Research direction
Investigate the permission denied error when running 'minikube image build'. The error indicates that the minikube process cannot read the Dockerfile inside the build directory. Examine the logs from both kvm2 and docker drivers (linked in issue). Check the file permissions and ownership of the build artifacts inside the minikube VM. Consider if the issue is related to how the build context is copied or extracted. See comments from maintainers for potential hints.
