Unable to install Git in Dockerfile

I am trying to run my Dockerfile but somehow I am unable to install Git. The problem is that installing it via “zypper” causes an error.

My Dockerfile looks like this:

RUN mkdir -p $HOME/images/lib/ && cd $HOME/images/lib/

RUN zypper update && zypper upgrade -y && zypper install -y git

#RUN apt-get update && apt-get upgrade -y && apt-get install -y git

RUN git clone URL

And when I run it I get the error:

Step 6/7 : RUN zypper update && zypper upgrade -y && zypper install -y git
—> Running in 02b2f3dff125
/bin/sh: zypper: not found
The command ‘/bin/sh -c zypper update && zypper upgrade -y && zypper install -y git’ returned a non-zero code: 127

I am using OpenSuse Linux VM to do this. LEAP 15.4.

My Docker version is:

Any help would be appreciated.

What is the base image? Have you installed zypper in the image before using it? The error message says zypper is not found.

PS.: Please, use code blocks (</> button) for terminal outputs and codes instead of quotes next time, so we can read and understand the question better.

The package manager you need to use depends on the os of the base image, not on the os of the host.

In order to use zypper as package manager, your Dockerfile must use a base image that actually provides it, like opensuse/leap:15 or opensuse/tumbleweed:latest.

Yes, I found this out the hard way. I was assuming since I was on OpenSuse, using zypper command would be the way to go. apk get and apk update does work.
