在docker容器中添加GPG密钥会导致"找不到有效的OpenPGP数据"

Question

我正在尝试在Docker容器中安装New Relic的系统监控,但是apt-key add -失败了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

Answer 1

@xdays提供的解决方案解决了这个问题,但也解决了ssl提供的保护问题.您可以ca-certificates在发出wget语句之前安装软件包,它应该与ssl一起使用.

在调用wget之前添加以下行:

RUN apt-get install -y ca-certificates wget

Answer 2

我在安装docker的时候遇到了这个问题。

跑步 sudo apt install apt-transport-https ca-certificates curl software-properties-common

你可以参考这里。

进而 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Answer 3

似乎问题是wget,添加--no-check-certificate到你的wget,一切都很好.

# wget --no-check-certificate -O- https://download.newrelic.com/548C16BF.gpg | apt-key add -
