como alterar o endereço de download do contêiner de pausa padrão do Kubernetes

  • 772

Devido ao problema de rede, quero alterar o contêiner de pausa padrão do Google do endereço oficial para endereços espelhados. Estou tentando alterar o endereço do contêiner de pausa padrão no Kubernetes v1.28.3assim:

root@k8sslave01:/var/lib/kubelet# cat /var/lib/kubelet/kubeadm-flags.env
KUBELET_KUBEADM_ARGS="--container-runtime-endpoint=unix:///var/run/containerd/containerd.sock --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.9"

quando reinicio o serviço kubelet, o endereço parece não funcionar. o que devo fazer para alterar o endereço padrão do contêiner de pausa do Google? Também tentei adicionar o --pod-infra-container-image=registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.6, ainda não consegui resolver o problema, o log do kubelet mostra erro:

root@k8sslave01:/etc/containerd# systemctl status kubelet -l --no-pager

    Você precisará aplicar isso ao seu caso e não tenho contexto suficiente para o seu log de erros, mas geralmente para alterar o endereço padrão do contêiner de pausa do Google no Kubernetes, tente as seguintes etapas:

    1. Edite o arquivo de configuração do kubelet normalmente localizado em /etc/systemd/system/kubelet.service.d/10-kubeadm.confou /etc/default/kubeletdependendo da sua configuração.

    2. Adicione ou modifique a KUBELET_EXTRA_ARGSlinha para incluir o --pod-infra-container-imagesinalizador com o endereço de espelho desejado. Por exemplo:

    KUBELET_EXTRA_ARGS="--pod-infra-container-image=your-mirror-address/pause:your-version"

    Substitua your-mirror-addresspelo endereço do espelho e your-versionpela versão desejada.

    1. Salve as alterações e reinicie o serviço kubelet:
    systemctl daemon-reload
systemctl restart kubelet

    Certifique-se de que o endereço do espelho esteja acessível e que a versão especificada do contêiner de pausa esteja disponível nesse endereço. Isso deve atualizar o endereço do contêiner de pausa para pods recém-criados.

    Se o problema persistir, verifique os logs do kubelet em busca de erros ou avisos que possam fornecer insights adicionais:

    journalctl -u kubelet

    Nota. Enfrentamos um problema semelhante com um serviço HostJane implantando um aplicativo no Kubernetes e as etapas acima alteraram com êxito o endereço do contêiner de pausa. Espero que ajude.
