配置国内镜像加速源

sudo mkdir -p /etc/rancher/k3s/
sudo tee /etc/rancher/k3s/registries.yaml <<'EOF'
mirrors:
  docker.io:
    endpoint:
      - "https://registry.cn-hangzhou.aliyuncs.com"
      - "https://docker.m.daocloud.io"
  registry.k8s.io:
    endpoint:
      - "https://registry.cn-hangzhou.aliyuncs.com"
      - "https://k8s.m.daocloud.io"
  ghcr.io:
    endpoint:
      - "https://ghcr.m.daocloud.io"

systemctl restart k3s
