sh: ./elastic-agent: 尝试 运行 Alpine Linux 上的弹性代理时未找到
sh: ./elastic-agent: not found when trying to run the elastic agent on Alpine Linux
我正在尝试在 docker 容器 运行 另一个服务上配置 Elastic Agent。该容器基于 Alpine Linux，但我无法 运行 下载并解压缩代理后的 elastic-agent 代理命令：它抱怨“找不到”文件，而该文件实际上存在!
这是一个最小的可复制示例
docker run --rm -it alpine sh

我运行正在 x86_64 主机上运行，可以从内核版本或软件包存储库中看出：

我错过了什么吗？ Alpine 能否在某些情况下阻止二进制文件启动？
感谢您的帮助！
问题好像是您下载的elastic-agent的编译版本需要libc。 Alpine linux 使用 muslc.
可以使用 在 alpine 中安装 glibc。然后 elastic-agent 似乎起作用了。
FROM alpine
WORKDIR /opt
RUN wget -qO - https://artifacts.elastic.co/downloads/beats/elastic-agent/elastic-agent-7.14.2-linux-x86_64.tar.gz \
| tar xz
# Add glibc
RUN wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub \
&& wget -q https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.28-r0/glibc-2.28-r0.apk \
&& apk add glibc-2.28-r0.apk \
&& rm glibc-2.28-r0.apk
和运行生成的图像（假设它被命名为elastic）：
