方法大致有二

• 手动导入ca-bundle.crt

cat ca.crt >> /etc/pki/tls/certs/ca-bundle.crt

如果是其他Linux发行版，该文件的位置可能是下面这些，视情况而定：

/etc/ssl/certs/ca-certificates.crt
/etc/ssl/ca-bundle.pem
/etc/ssl/cert.pem
/usr/local/share/certs/ca-root-nss.crt

• 通过 ca-certificates

 yum install -y ca-certificates
sudo cp ca.crt /usr/local/share/ca-certificates/kubernetes.crt
sudo update-ca-certificates


# Updating certificates in /etc/ssl/certs...
# 1 added, 0 removed; done.
# Running hooks in /etc/ca-certificates/update.d....
# done.
