Dear All, OS Version: Docker based Rancher v2.6.13 container on centOS 7 as Base. Problem-Statement: 4 Rancher cluster drivers are continuously in downloading state, Which are required for creating clusters in respective hosted kubernetes providers, as follows: 1. Alibaba ACK. 2. Baidu CCE. 3. Huawei CCE. 4. Tencent TKE. So, I checked logs of rancher container, which has following errors: 2023/10/30 093739 [ERROR] error syncing 'tencentkubernetesengine': handler mgmt-kontainer-driver-lifecycle: Get "https://drivers.rancher.cn/kontainer-engine-driver-tencent/0.3.0/kontainer-engine-driver-tencent-linux": dial tcp: lookup drivers.rancher.cn on 196.1.105.47:53: no such host, requeuing 2023/10/30 093739 [ERROR] error syncing 'huaweicontainercloudengine': handler mgmt-kontainer-driver-lifecycle: Get "https://drivers.rancher.cn/kontainer-engine-driver-huawei/0.1.2/kontainer-engine-driver-huawei-linux": dial tcp: lookup drivers.rancher.cn on 196.1.105.47:53: no such host, requeuing 2023/10/30 093739 [ERROR] error syncing 'baiducloudcontainerengine': handler mgmt-kontainer-driver-lifecycle: Get "https://drivers.rancher.cn/kontainer-engine-driver-baidu/0.2.0/kontainer-engine-driver-baidu-linux": dial tcp: lookup drivers.rancher.cn on 196.1.105.47:53: no such host, requeuing 2023/10/30 093739 [ERROR] error syncing 'aliyunkubernetescontainerservice': handler mgmt-kontainer-driver-lifecycle: Get "https://drivers.rancher.cn/kontainer-engine-driver-aliyun/0.2.6/kontainer-engine-driver-aliyun-linux": dial tcp: lookup drivers.rancher.cn on 196.1.105.47:53: no such host, requeuing Steps taken to find the root cause: [In Client Machine] 1. Checked for the domain name resolution: [root@ranchert home]# nslookup drivers.rancher.cn Server: 196.1.105.47 Address: 196.1.105.47#53 ** server can't find drivers.rancher.cn: NXDOMAIN 2. Ping the domain name: [root@ranchert home]# ping drivers.rancher.cn ping: drivers.rancher.cn: Name or service not known I checked the same commands for the same domain name in my local machine, whose output is as follows: 1. lenovo@aman:~$ ping drivers.rancher.cn ping: drivers.rancher.cn: Name or service not known 2. lenovo@aman:~$ nslookup drivers.rancher.cn Server: 127.0.0.53 Address: 127.0.0.53#53 Non-authoritative answer: drivers.rancher.cn canonical name = drivers.rancher.cn.w.kunlungr.com.
