I'm installing minikube as part of below Dockerfile:

FROM jenkins/jnlp-agent-alpine
RUN curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && \
        install minikube-linux-amd64 /home/jenkins/minikube -o jenkins -g jenkins -m 777 && \         
        rm minikube-linux-amd64

Once image is built and run:

$docker build -t app:latest .
$docker run -it app:latest bash

#minikube` binary exists

bash-5.1$ls -l minikube 
-rwxrwxrwx    1 jenkins  jenkins   74953166 Jul 19 15:44 minikube

#however running the binary `minikube` returns `No such file or directory` error:

bash-5.1$ ./minikube 
bash: ./minikube: No such file or directory

As part of debugging, I made jenkins user owner of minikube and set its permissions to be 777, though it still didn't help.

Why does No such file or directory error pop and how to solve it?

The minikube binary is linked against the GNU C library, but your image is based on Alpine which uses musl. Running minikube fails because the dynamic linker it specifies (/lib64/ld-linux-x86-64.so.2) isn’t present.

If you want to use minikube, you need to either find a musl-based build (or a static build), or switch to a base image which uses the GNU C library.

I was able to run minikube using below command inside the container:

/lib/ld-musl-x86_64.so.1 minikube
