Cant cd to cloned repo via Dockerfile

I’m creating a Dockerfile, but seem to be having some issues navigating to the folder of a cloned repo

My file contains the below

FROM ubuntu:latest
MAINTAINER cagnulein

ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Europe/Moscow
ENV MAKEFLAGS -j8
WORKDIR /usr/local/src

RUN apt-get update && apt-get install -y tzdata
RUN apt -y update
RUN apt -y upgrade
RUN apt update -y && apt-get install -y git qt5-default libqt5bluetooth5 libqt5widgets5 libqt5positioning5 libqt5xml5 qtconnectivity5-dev qtpositioning5-dev libqt5charts5-dev libqt5charts5 qt5-default libqt5networkauth5-dev libqt5websockets5* libxcb-randr0-dev libxcb-xtest0-dev libxcb-xinerama0-dev libxcb-shape0-dev libxcb-xkb-dev build-essential
RUN cd ~
RUN git clone https://github.com/cagnulein/qdomyos-zwift.git
RUN ls -alh
RUN cd ~/qdomyos-zwift

I successfully clone the repo, and can confirm the folder exists, but I can’t seem to navigate to it as I get the following

#13 [ 9/15] RUN ls -alh
#13 sha256:4b5dfb1969e228b79ed0f0d06393eddbc97c0197582b068ad75b1e5672597867

#14 0.437 /bin/sh: 1: cd: can't cd to /root/qdomyos-zwift
#14 ERROR: executor failed running [/bin/sh -c cd ~/qdomyos-zwift]: exit code: 2

Any ideas?

Tried

WORKDIR ~
RUN git clone https://github.com/cagnulein/qdomyos-zwift.git
RUN ls -alh
WORKDIR ~/domyos-zwift
RUN git submodule update --init src/smtpclient/

which fails with

#13 0.466 fatal: not a git repository (or any of the parent directories): .git
#13 ERROR: executor failed running [/bin/sh -c git submodule update --init src/smtpclient/]: exit code: 128

    ~ is a shorthand for $HOME, the user’s home directory. In this case this is /root. But as your ls command shows, the repo’s directory is in the current directory. If you do pwd, you will see the current directory is not /root. Instead do cd qdomyos-zwift so that it is relative to the current directory.

    Notice in your example that you already have seen the mechanism to set the current directory: WORKDIR.

    Replace all of your RUN cd ... statements with WORKDIR /path instead. That’s the correct way to set the current directory in a Dockerfile.

    If you need to be in another place at the end of your build, remember to add a WORKDIR toward the end of the file to leave that as the working directory in the final image.

    Your cd manipulations seem confused and completely unnecessary. Probably try something along the lines of

    WORKDIR /usr/local/src

RUN apt-get update && apt-get install -y tzdata
# RUN apt -y update  # no need, you just did
RUN apt -y upgrade
# RUN apt update -y &&  # no need, you just did
RUN apt-get install -y git qt5-default libqt5bluetooth5 
     libqt5widgets5 libqt5positioning5 libqt5xml5 
     qtconnectivity5-dev qtpositioning5-dev libqt5charts5-dev 
     libqt5charts5 qt5-default libqt5networkauth5-dev 
     libqt5websockets5* libxcb-randr0-dev libxcb-xtest0-dev 
     libxcb-xinerama0-dev libxcb-shape0-dev libxcb-xkb-dev 
     build-essential
RUN git clone https://github.com/cagnulein/qdomyos-zwift.git
WORKDIR /usr/local/src/qdomyos-zwift

    … assuming you would like to continue to run some commands in the directory you just cloned.
