将我在搭建kubernetes集群过程中遇到的一些比较棘手的问题记录下来。
1.docker.service failed.
journalctl -xn 查看内核日志
Error starting daemon: error initializing graphdriver: driver not supported [graphdriver] prior storage driver devicemapper failed: driver not supported devmapper: Udev sync is not supported. This will lead to data loss and unexpected behavior.
解决方案:
Answer: I managed to resolve this on my side by deleting /var/lib/docker and restarting the docker service. ** I’m really not sure what caused it and it may be due to packaging issue in my case. **Note: Removing /var/lib/docker will delete all your downloaded images!
尤其注意最后一句，会将本地的镜像全部删除，因为需要最好备份工作，将镜像导出，再docker服务重新启动后再load回来。
