Lab 4 - Setting Up Continuous Integration with Jenkins - Page 2 - Error while building

Get the following error message when trying to build the docker compose.

Package 'docker-ce-cli' has no installation candidate

Screenshot of the Lab Page 2 and the Error Output are attached with this message.

I guess the package docker-ce-cli isn’t there in the image?

    @ericegan I guess I’ve figured out the issue. The package docker-ce-cli isn’t available for the arm64 arch. I tried to execute the steps inside the docker image manually and after I reached the step where I need to install the docker-ce-cli package, it failed, as expected.
    I listed the packages, and figured out the arch is different. I am on arm64. But the docker image is a amd64, do you think it should still work?

    Or maybe the Dockerfile line which adds the repository to the image, needs to be ammended,

    1. RUN add-apt-repository \
    2. "deb [arch=amd64] https://download.docker.com/linux/debian \
    3. $(lsb_release -cs) stable”

    It clearly says arch=amd64 in there.

    I modied the Dockerfile and used the correct arch for my laptop here, the issue did not happen.
    I have attached the terminal output from the run with arch set to amd64 with this ticket.

    The output from the terminal where I set the arch to arm64 is below:

    1. root@cf3526be43ee:/# add-apt-repository "deb [arch=arm64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
    2. root@cf3526be43ee:/# apt-get update && apt-get install -y docker-ce-cli

    So I guess this works for me for now.

  • Hi @Shivinder , I have seen more than one issue when working with arm based systems (in more than just this course). So you may expect some trouble, perhaps in performance and other stuff.

    Regards,
    Luis.
