skaffold部署期间提取pod日志

Question

我们对使用k3s和skaffold在本地部署（到CI构建代理）的应用程序运行了一些自动化测试。

当我们运行skaffold部署-状态检查时，我们如何查看（标准输出或文件）pod日志？（我们在部署期间遇到了错误，除非我们ssh到构建代理上，否则我们无法看到这些错误。）

以下内容在部署成功后运行时会捕获日志，但如果我们在运行skaffold deploy之前运行它，则不会起作用，可能是因为它不会拾取在运行此命令后启动的任何pod：

kubectl logs \
    --namespace x \
    --follow \
    --ignore-errors \
    --max-log-requests 50 \
    --all-containers \
    --prefix \
    --timestamps \
    --selector release=y >"k8s.log" 2>&1 &

skaffold deploy--状态检查的输出如下所示：

Answer 1

@Graham Russell--statation-check应该记录失败的pod，如果它们存在的话。我唯一能想到的是pod容器终止并在skaffold可以获取日志之前被清理。

在所有部署稳定之前，目前无法将日志流式传输到std。

可以粘贴当前状态检查输出吗

Answer 2

我发现stern可以处理添加到命名空间的新pod。

因此，跑步：

stern-n名称空间。

在skaffold部署之前。
