I am trying to deploy my application into Rancher managed kubernetes cluster RKE. I have created pipeline in gitlab using auto devops. But when the helm chart is trying to deploy I get this error. Error: Kubernetes cluster unreachable: Get "http://localhost:8080/version?timeout=32s": dial tcp 127.0.0.1:8080: connect: connection refused

Below is my deploy script:

deploy:
  stage: deploy
  image: cdrx/rancher-gitlab-deploy
  only:
    - master
  script:
    - apk --no-cache add curl
    - curl -L https://get.helm.sh/helm-v3.3.0-rc.1-linux-amd64.tar.gz > helm.tar.gz
    - tar -zxvf helm.tar.gz
    - mv linux-amd64/helm /usr/local/bin/helm
    - helm install mychart ./mychart

Could someone help me in resolving this issue

what is the api url you gave in Gitlab autodevops setup ? – Tarun Khosla
sounds like it doesn't know how to connect to your RKE cluster – Rico
Hello, have you managed to solve your issue with the help of Rico's comment? – Dawid Kruk
I already configured the integration with RKE cluster by adding the api url,token of the cluster in gitlab project settings..not sure what else has to be configured.still getting same error – merla
The issue is fixed after explicitly adding environment variable to deploy script. Thanks for the help – merla

I've bumped into the same issue when installing rancher on K3s, setting KUBECONFIG helped.

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

This anwser solved the issue for me. If you're not running on microk8s, like me, omit the prefix

[microk8s] kubectl config view --raw > ~/.kube/config
