这是我没有得到的jar文件。它说丢失了lib/glowroot-embedded-collector.jar
,即使该位置上存在{1>}。

这是我的docker文件内容:

请让我知道这个问题。 jar位于lib/glowroot-embedded-collector.jar
答案 0 :(得分:1)
在Dockerfile中,您具有:
ADD /opt/glowroot/lib/glowroot-embedded-collector.jar glowroot-embedded-collector.jar
这会将jar文件复制到根目录中,因此可以在以下位置找到它:/glowroot-embedded-collector.jar
当您说lib / glowroot-embedded-collector.jar可用时,是指在主机上还是在容器内?因为基于您的Dockerfile,我认为它不能存在于容器中。
也许尝试以这种方式更改ADD语句:
ADD /opt/glowroot/lib/glowroot-embedded-collector.jar lib/glowroot-embedded-collector.jar
