/kubesphere-all-v2.1.1/k8s/roles/download/defaults/main.yml 中的download_validate_certs = True 报Failed to validate the SSL certificate for kubernetes-release.pek3b.qingstor.com:443. Make sure your managed systems have a valid CA certificate installed. You can use validate_certs=False if you do not need to confirm the servers identity but this is unsafe and not recommended. Paths checked for this platform: /etc/ssl/certs, /etc/pki/ca-trust/extracted/pem, /etc/pki/tls/certs, /usr/share/ca-certificates/cacert.org, /etc/ansible. The exception msg was: EOF occurred in violation of protocol (_ssl.c:618).
