jmeter - 错误：不可满足的约束：curl（缺失）：为 jmeter dockerfile 构建时

问题描述

我无法构建 jmeter docker 文件，出现以下错误。

如果有任何遗漏，谁能告诉我

解决方案

该错误表示Alpine apk包管理工具无法安装curl，fontconfig其他包由于无法连接到http://dl-cdn.alpinelinux.org/alpine/v3.9/main/x86_64/主机并从那里获取文件。

确保您的主机具有 Internet，如果它确实遵循My docker 容器中的建议，则没有 Internet答案。

另请注意，目前JMeter 5.2已发布，因此我建议至少更改此行：

ENV MIRROR https://www-eu.apache.org/dist/jmeter/binaries

对此：

ENV MIRROR https://archive.apache.org/dist/jmeter/binaries

否则，即使您解决了 Internet 连接问题，您的Dockerfile也将无法工作。

您可以选择升级JMETER_VERSION以匹配最新的稳定 JMeter 版本
