An error is reported when an executable file packaged by a project is executed in the alpine container

Solution:

It is judged that the lack of dependent environment leads to the unrecognization of this executable file. Install glibc to solve the problem

You can also directly change the from image to busybox: glibc

cat Dockerfile 
FROM alpine:3.14
COPY xxx /tmp/
ARG TZ="Asia/Shanghai"
ENV TZ ${TZ}
RUN  mkdir -p /opt/xxx && mv /tmp/xxx /tmp/ysera_mgtv.conf  /opt/xxx && \
     chmod 777 /opt/xxx/xxx && \
     sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories  && \
     apk add tzdata && ln -sf /usr/share/zoneinfo/${TZ} /etc/localtime  && \
     wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub && \
     wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.29-r0/glibc-2.29-r0.apk && \
     apk add glibc-2.29-r0.apk
