Since Docker is the future (satire) I decided to try it out.

If everything is alright you should be able to install the latest version just by running the following, otherwise check the documentation. Don’t forget to replace username with your actual username.

$ wget -qO- https://get.docker.com/ | sh
sudo usermod -aG docker username

To verify if the installation worked well run

sudo docker run hello-world

The command above downloads a test image and runs in its container

Personally, I’ve encountered an error running this command and I had to restart the system to make it work after trying some other commands found on StackOverflow to fix this.

FATA[0000] Post http:///var/run/docker.sock/v1.18/containers/create: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS? 

Ubuntu is like Windows, small problem: restart, serious problem: reinstall (/s)

Run WordPress in Docker (WP setup will be available at 127.0.0.1)

docker pull tutum/wordpress
docker run -p 80:80 tutum/wordpress

That’s pretty awesome and fast, though don’t know yet how to make any changes on it or where are the files actually located.

Useful Docker commands

Show running containers

sudo docker ps

Show all images in your local repository

sudo docker images

Run a container from a specific image

sudo docker run -i -t <image_id || repository:tag> -bash

Start a existing container

sudo docker start -i <image_id>

Exit without shutting down a container

[Ctrl-p] + [Ctrl-q]

Upgrade Docker

wget -N https://get.docker.com/ | sh

Stop all containers

docker stop $(docker ps -a -q)

Remove all containers

docker rm $(docker ps -a -q)

TBC.
