Error from server (NotFound)

Oi Jackson, boa tarde. Tudo bem?

Qual a saída do seu comando kubectl describe sts sistema-noticias-statefulset?

Respondendo a segunda pergunta: não fui eu que adicionei. Esse 0 foi adicionado pelo próprio Kubernetes como um índice para indicar que esse é o primeiro Pod desse conjunto.

Pelo que vi ficou faltando uma letra n na palavra imagens durante a declaração do seu statefulset.

Como está o seu arquivo de definição do statefulset e dos volumes de imagens?

Obrigado Daniel, faltava a letra n, você está certo, por esse motivo que o Kubernetes não estava criando o índice pod como você me explicou, porém agora o status esta peding

Eu já conseguir identificar um erro de digitação no arquivo imagens-pvc.yaml, eu corrigir o erro, deletei o arquivo e criei novamente e funcionou!! Obrigado Daniel pela ajuda!!!

Disponha Jackson. Bons estudos :)
