Error connecting to k8s cluster: Get "https://172.26.0.18/version"

Hello World!

I'm following https://github.com/txn2/kubefwd#docker and while kubefwd mostly works for me, there are other times when it doesn't, like so:

% docker run -it --rm --privileged --name the-project \
    -v "$(echo $HOME)/.kube/":/root/.kube/ \
    txn2/kubefwd services -n the-project

I've tried to mount my google-cloud-sdk, however now it's missing python...

Is there another way to handle that error? as API IS reachable:

/ # curl -skI https://172.26.0.18/version | head -1
HTTP/2 403 
/ # 

Please advise.

I have not used the kubefwd docker container with gcloud. I suggest creating a new container with kubefwd and Python installed.

[a1exus]

% cat Dockerfile 
FROM google/cloud-sdk:alpine as cloud-sdk
COPY --from=cloud-sdk /google-cloud-sdk/ /google-cloud-sdk/ 

FROM python:alpine as python
COPY --from=python /usr/local /usr/local

FROM txn2/kubefwd:latest
% 

also, I found these useful as well:

% grep -A3 environment docker-compose.yml 
    environment:
      - CLOUDSDK_PYTHON="/usr/local/bin/python"
      - CLOUDSDK_CONFIG="/google-cloud-sdk/config"
      - PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/google-cloud-sdk/bin
