For installation of Docker on Windows 10 with Hyper-V capacity ( Check if Hyper-V is available by using Speccy ) If Win 10 + Hyper-V
=> Docker Desktop
( https://hub.docker.com/editions/community/docker-ce-desktop-windows)
Without Hyper-V or with another version of Windows
=> Docker Toolbox
( https://docs.docker.com/toolbox/overview/ )

For Mac users, it's there => ( https://docs.docker.com/docker-for-mac/install/ )

Ubuntu from Repository:

Updating:

sudo apt-get update

Installation from repository:

sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common

Official Docker GPG key :

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Let's check the fingerprint:

sudo apt-key fingerprint 0EBFCD88

it must look like this ->

pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <docker@docker.com>
sub   rsa4096 2017-02-22 [S]

This command line will install latest stable release of Docker:

sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

Docker installed! Let's check this!!! =>

sudo docker run hello-world
container doesn't exist locally, it'll be downloaded the first time we run it

Linux Post-install

Avoid using sudo command each time you want to use a docker command, by including actual user to a docker group

Create group: sudo groupadd docker

Put user into the new docker group: sudo usermod -aG docker $YOUR_USER

Log out from your session et log in. Now, we'll test a command line without sudo docker run hello-world

If there's a warning about ~/.docker/ permissions -> Remove folder ~/.docker/ or change rights and permissions on it
sudo chown "$USER":"$USER" /home/"$USER"/.docker -R sudo chmod g+rwx "$HOME/.docker" -R

Docker compose

Linux only! If you have Mac OS or Windows, with Docker Desktop, Docker Compose is already installed
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Now, give rights to execute
sudo chmod +x /usr/local/bin/docker-compose

and let's try it!!
docker-compose --version

In case of a problem due to path, we can create a symbolic link
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

We'll need a Docker Hub account also, it's a container repository where we can keep our own images: https://hub.docker.com/

And if you need to deploy your app, several options are there!!

• Amazon Web Services (Need a credit card to activate free services)
• Google Cloud
• Microsoft Azure (Need a credit card to activate free services)
• Heroku (Free)
• Jelastic Cloud (A 14 days free trial)
