Question

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

运行skaffold deploy --status-check时如何查看（stdout或文件）pod日志？（在部署过程中，我们遇到了一些错误，除非我们使用ssh到构建代理程序，否则这些错误是看不到的。）

以下内容在成功部署后运行时会捕获日志，但是如果我们在运行skaffold deploy之前运行它，这将不起作用，大概是因为它没有拾取运行后启动的任何Pod该命令：

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

skaffold deploy --status-check的输出看起来像这样：

Answer 1

我发现stern可以应付添加到名称空间的新容器。

因此，运行：

stern -n namespace . >my.log &

在skaffold deploy完成之前。

Answer 2

@Graham Russell --status-check应该记录已失败的Pod。我唯一能想到的就是Pod容器被终止并且在skaffold可以抓住日志之前被清理了。

当前无法在所有部署稳定之前将日志流传输到std。

您可以粘贴当前的status-check输出

在skaffold部署期间提取pod日志
