Docker Install For Me

While you can find articles and vast amounts of tutorials on how to install Docker. This is another one of those for my own purpose, if you find it helps you that's great and have yourself a good day. Most things here will be straight lifted from Docker's guide to install Docker on Ubuntu > Here

Let's start basically copy pasting the commands into terminal on Ubuntu 22.04.

 sudo apt-get update

 sudo apt-get install \
    ca-certificates \
    curl \
    gnupg

This gets us to use Docker's repository over HTTPS with the "apt" command

sudo install -m 0755 -d /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg

Adding Docker’s official GPG key

echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Setting up the Docker repository

sudo apt-get update

Updating the apt-get package index since we added Docker in

The next command installs the Docker on to your machine.

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

To install the latest version

Now verify that Docker installed correctly.

sudo docker run hello-world

Hello world docker container test, it print out hello world as confirmation it was installed correctly.

Now let's make sure that Docker starts with the system after reboot.

sudo systemctl enable docker.service

sudo systemctl enable containerd.service

If you want to stop this behaviour use "disable" where "enable" is.

With that out of the way you should now have Docker installed and ready for containerizations.

If any of this helped I'm glad.
