  1. By default, pd uses nslookup for domain name resolution during startup, but the nslookup included in the 6.5.0 pd image is not available by default;
  2. According to the official website, modify the startUpScriptVersion configuration to use dig for domain name resolution during startup. In this case, the domain name can be resolved, but wget (the path of wget contains the domain name) is not available during the startup process;
  3. During the troubleshooting process, it was found that commands like ping are also unavailable.
