# Ubuntu

### Installation Guide

1. Update the apt package index and install packages to allow apt to use a repository over HTTPS

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

2\. Add Docker’s official GPG key:

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

3\. Verify that the key has the fingerprint`9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88`, by searching for the last 8 characters of the fingerprint.

```
sudo apt-key fingerprint 0EBFCD88
```

> 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]

4\. Set up the docker repository

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

5\. Update the apt package index, and install the latest version of Docker Engine and containerd

```
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
```

6\. Create the docker group.

```
sudo groupadd docker
```

7\. Add user to the docker group.

```
sudo usermod -aG docker $USER
```

8\. Log out and log back in so that your group membership is re-evaluated.

9\. To confirm that Docker has been installed, check the docker version using

```
docker --version
```
