image 별도로 push 방법

sudo ./kk artifact image push -f config-sample.yaml -a artifact-3.0.7.tar.gz

[ERROR] Harbor에 image push 할 때 Unauthorized 에러 발생 때

  • 다시 로그인
    1

    docker login [your.host.com]:port -u username -p password

Cluster 설치

1

sudo ./kk create cluster -f config-sample.yaml -a artifact-3.0.7.tar.gz

Install operating system packages

1

sudo ./kk create cluster -f config-sample.yaml -a artifact-3.0.7.tar.gz --with-packages

--skip-push-images를 추가하면 harbor에 image를 push하는 과정으로 생략할 수 있다.

1

sudo ./kk create cluster -f config-sample.yaml -a artifact-3.0.7.tar.gz --skip-push-images

kubekey command 참고

Cluster 설치하면서 log 확인

1

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f
