Docker错误: /usr/local/bin/docker-entrypoint:第7行: /usr/local/bin/env2yaml:无法执行二进制文件

Question

我正在尝试使用centos:7作为PPC64LE架构上的基础镜像来构建logstash 7.6.0镜像。

FROM centos:7
COPY bin/docker-entrypoint /usr/local/bin/
COPY env2yaml/env2yaml /usr/local/bin/
ENTRYPOINT ["/usr/local/bin/docker-entrypoint"]

镜像已成功构建，但会出现以下错误：

[root@p006vm32 logstash]# docker run -it logstash:7.6.0
/usr/local/bin/docker-entrypoint: line 7: /usr/local/bin/env2yaml: cannot execute binary file

Answer 1

给定env2yaml是一个go可执行文件，它假定您已经将其编译为ppc64le可执行文件。

之后，通过在COPY之后在Dockerfile文件中包含以下内容来启用执行权限

RUN chmod a+x /usr/local/bin/env2yaml
