Linux Mint Cinamon

Below are the notes to get it going on my Mint server(s). Cribbed from the web, and recorded here for my own future use:

//https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#uninstall-old-versions

//docker.io was the ubuntu maintained image - to avoid name conflict with their ui docker.
// Now the image is docker.ce, so no conflict, therefore
sudo apt-get remove docker docker-engine docker.io
sudo apt-get update
sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

// confirm
sudo apt-key fingerprint 0EBFCD88

      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88

// if you get a warning about mir, its related to the below, which is harmless.
export DISPLAY=:0

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

// If that failed then do, because trusty is the actual name we need then
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   trusty \
   stable"

// Note you can directly update the list as well via below - so you can tidy it up
sudo vi /etc/apt/sources.list.d/additional-repositories.list

sudo apt-get update
sudo apt-get install docker-ce

// if fails on libsystemd-journal0, http://packages.ubuntu.com/trusty/i386/libsystemd-journal0/download
edit as sudo /etc/apt/sources.list
add line below:
deb http://cz.archive.ubuntu.com/ubuntu trusty main

Then
sudo apt-get update
sudo apt-get install docker-ce


sudo docker run hello-world
sudo groupadd docker
sudo usermod -aG docker $USER
//logout and in again
groups
docker run hello-world

// Any problems, then change persmissions of your .docker dir
sudo chown "$USER":"$USER" /home/"$USER"/.docker -R
sudo chmod g+rwx "/home/$USER/.docker" -R

// make it start on reboot
sudo systemctl enable docker
