Create a Podman container

Install Podman

Podman is an easy and safe way for running containers. In Ubuntu or Debian it can be installed with:

sudo apt install podman

Create the container

podman run -d \
--name linux-cli --hostname linux-cli \
docker.io/dashohoxha/linux-cli:latest

podman ps
note

The command above is downloading a pre-made image from docker hub: docker.io/dashohoxha/linux-cli:latest

If you want, you can build the image yourself (although it may take longer).

How to build your own image:
  1. Download the Dockerfile, or copy/paste it from here:

    Dockerfile
    FROM ubuntu:24.04

    ### install systemd
    RUN apt update && \
    apt upgrade --yes && \
    apt install --yes systemd && \
    systemctl set-default multi-user.target

    CMD ["/sbin/init"]

    RUN yes | unminimize

    RUN DEBIAN_FRONTEND=noninteractive \
    apt install --yes \
    task-mate-desktop \
    ubuntu-mate-core \
    task-ssh-server

    RUN apt install --yes \
    mandoc less info plocate bash-completion \
    wbritish highlight elinks ncal tree \
    nano jed vim emacs netcat-openbsd \
    iputils-ping traceroute iputils-tracepath \
    rsync aspell lynx highlight git tmux

    ### enable dark background for vim
    RUN sed -i /etc/vim/vimrc -e 's/^"set background=dark/set background=dark/'

    ### set a better prompt for the root
    RUN PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u\[\033[01;33m\]@\[\033[01;36m\]\h \[\033[01;33m\]\w \[\033[01;35m\]\$ \[\033[00m\]' && \
    echo "PS1='$PS1'" >> /root/.bashrc

    ### add user (user1, pass1) and improve its prompt
    RUN useradd -m -s /bin/bash -G sudo user1 && \
    echo user1:pass1 | chpasswd && \
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;33m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ \[\033[01;32m\]' && \
    echo "PS1='$PS1'" >> /home/user1/.bashrc && \
    x='"\033[00m"' && echo "trap 'echo -ne $x' DEBUG" >> /home/user1/.bashrc
  2. Build the image:

    podman build --rm -t localhost/linux-cli:latest .
  3. Create and start the container:

    podman run -d \
    --name linux-cli --hostname linux-cli \
    localhost/linux-cli:latest

Using the container

  • To get a shell as user1 inside the container, use this command:

    podman exec -it -u user1 -w /home/user1 linux-cli bash
  • For convenience, create an alias like this:

    alias linux-cli='podman exec -it -u user1 -w /home/user1 linux-cli bash'

    Now, whenever you type linux-cli you will get a shell inside the container.

    note

    Append this alias to ~/.bashrc to make it persistent.

info
  • Inside the container, use sudo su to get root access. The default password of user1 is pass1.

  • If you need to recreate the container, you should remove the existing one first:

    podman rm -fi linux-cli
