Eu atualizei o cluster Kubernets (3 mestres, 3 bancos de dados de servidores etcd) de 1.18para v1.19.13e ETCD para 3.4.13. como os servidores API não são estáveis, continue trocando de servidor etcd diferente, porque esse cluster não está funcionando corretamente. esses clusters rodando no CentOS Steam 8. Este cluster funcionou antes da atualização, somente após a atualização eu vi esse problema.
Alguma ajuda para resolver esse problema? Existe algum problema com esta versão?
