My first experiment with Docker after reading Jessie’s Docker Containers on the Desktop.
Table of Contents
The Console
Try Ubuntu image:
docker pull ubuntu
docker run ubuntu # Runs Ubuntu and exits
docker run [--interactive -i] [--tty -t] ubuntu
Install Kakoune inside the Docker container:
apt update
apt install git pkg-config libncursesw5-dev
git clone https://github.com/mawww/kakoune repositories/github.com/mawww/kakoune
cd repositories/github.com/mawww/kakoune/src
make install
kak
exit
Exited Ubuntu.
docker run --interactive --tty ubuntu
Ubuntu:
kak
# bash: kak: command not found
Kakoune is not installed??
Docker’s like Git

When you use
docker runto start a container, it actually creates a new container based on the image you have specified.
You need to commit the changes you make to the container and then run it.
Exited Ubuntu.
docker ps [--all -a]
# CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
# dbf27ffc058d ubuntu "/bin/bash" About an hour ago Exited (0) About a minute ago shinichi
docker attach shinichi
# You cannot attach to a stopped container, start it first
docker start shinichi
docker attach shinichi
Exited Ubuntu.
docker commit shinichi shinichi
Just testing:
docker run --interactive --tty shinichi
Exited Ubuntu.
docker ps [--latest -l]
# CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
# 15529bec5b53 shinichi "/bin/bash" About a minute ago Exited (0) About a minute ago tashigi
