Problema: Estou executando o Wiki.js em um cluster zonal do GKE e estou encontrando um problema com minha configuração do Ingress. O controlador do Ingress retorna "Todos os serviços de backend estão em estado UNHEALTHY" e o grupo de endpoints de rede zonal mostra 0/1 endpoints operacionais. Isso acontece após editar as configurações no painel de administração do wikijs.

Ambiente:

  • Cluster Zonal do GKE
  • Versão do Wiki.js: 2.5

Situação atual:

  • Todos os pods estão funcionando
  • ainda é possível conectar-se ao wikijs através do IP do serviço
  • Grupo de endpoint de rede zonal: 0/1 operacional

Configuração atual:

Questões:

  1. O que pode estar causando o "estado NÃO ÍNTEGRA" no Ingress?
  2. Por que os pontos de extremidade da rede estão mostrando 0/1 operacional?
  3. Há alguma configuração específica do GKE que eu deva verificar?

Problema: Estou executando o WikiJS no Kubernetes (GKE) e estou encontrando problemas de permissão. O aplicativo não consegue criar o diretório de cache, gerando: "EACCES: permissão negada, mkdir '/wiki/data/cache'"

Ambiente:

  • Kubernetes: GKE
  • Versão do WikiJS: 2.5
  • Volume: PVC

Pergunta : Como posso configurar corretamente as permissões para o pod WikiJS gravar em seu diretório de dados? O volume está montado, mas o aplicativo não consegue criar os diretórios necessários.
