在Docker容器中添加GPG密钥导致“没有找到有效的OpenPGP数据” [英] Adding GPG key inside docker container causes "no valid OpenPGP data found"

问题描述

我正在尝试在Docker容器中安装New Relic的系统监控，但是 apt-key add - 失败，没有有效的OpenPGP数据发现。

I'm trying to install New Relic's system monitoring inside a docker container, but the apt-key add - fails with no valid OpenPGP data found.

有完整的 Dockerfile ：

FROM ubuntu
MAINTAINER Matej Koubik

RUN echo deb http://apt.newrelic.com/debian/ newrelic non-free >> /etc/apt/sources.list.d/newrelic.list
RUN wget -O- https://download.newrelic.com/548C16BF.gpg | apt-key add -
RUN apt-get update
RUN apt-get install newrelic-sysmond
RUN nrsysmond-config --set license_key=...
RUN /etc/init.d/newrelic-sysmond start

推荐答案

通过@xdays解决问题，但也围绕ssl提供的保护。您可以安装 ca-certificates 包，然后发出你的wget语句，它应该使用ssl。

The solution provided by @xdays works around the problem, but also works around the protection that ssl is providing. You could install the ca-certificates package before issuing your wget statement and it should work with ssl.

在调用wget之前添加以下行：

Add the following line before your call to wget:

RUN apt-get install -y ca-certificates wget
