Error with polarstack-daemon.
I install polardb by install.sh and I have modify env.yaml according to my own configuration. However, pod created by polarstack-daemon can't work properly. Here is the log of the pod.

please make sure that all the hosts can be logined by ssh without password. such as ssh host1(without needing to input password of root)
https://github.com/ApsaraDB/PolarDB-Stack-Operator/blob/master/docs/install_quick.md 每台机器互相之间已经配置好免密 ssh, 每台主机都可在当前root用不下通过ssh hostx的方式登录自己， 例如在主机1上， ssh host1, 在主机2上ssh host2， 以此类推
I have solved it now. And I find another reason: PublicKeyFilePath is hard coded in PolarDB-Stack-Daemon's sshtuil.go. The path happends to be /root/.ssh/id_ed25519 in my machine instead of /root/.ssh/id_rsa, which cause this problem.😑
