我将我的docker镜像从php:7.1.11-apache升级到php:7.2.0-apache(FROM debian:stretch-slim)后，google-fluentd软件包未找到/安装。
当我尝试在GKE中构建docker镜像并安装google fluentd (https://dl.google.com/cloudagents/install-logging-agent.sh)时，输出如下:
W: GPG error: http://packages.cloud.google.com/apt google-cloud-logging-wheezy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3746C208A7317B0F
W: The repository 'http://packages.cloud.google.com/apt google-cloud-logging-wheezy InRelease' is not signed.
当我运行容器镜像时，由于未安装该软件，出现了以下错误：
/bin/sh: 1: /etc/init.d/google-fluentd: not found
按照指南https://cloud.google.com/logging/docs/agent/installation，我发现支持Debian 8。
您知道是否有任何解决此问题的变通方法或修复方法吗？
谢谢。
