So I recently got introduced to Tensor Flow and a whole lot of other platforms that requires me to install Docker on my machine, and yeah had a bit of challenges finding the right resources to make my journey, then came this tutorial I found on Digital Ocean community, awesome stuff!!! #UnsongHero… Lol
And just incase you wondering what Docker is, here is a brief definition:
Docker is an application that makes it simple and easy to run application processes in a container, which are like virtual machines, only more portable, more resource-friendly, and more dependent on the host operating system.
Okay now since we done with that, we may get to installing Docker…
Step 1 — Installing Docker
The Docker installation package available in the official Ubuntu 16.04 repository may not be the latest version. To get the latest and greatest version, install Docker from the official Docker repository. This section shows you how to do just that.
But first, let’s update the package database:
sudo apt-get update
Now let’s install Docker. Add the GPG key for the official Docker repository to the system:
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
Add the Docker repository to APT sources:
sudo apt-add-repository 'deb https://apt.dockerproject.org/repo ubuntu-xenial main'
Update the package database with the Docker packages from the newly added repo:
sudo apt-get update
Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:
apt-cache policy docker-engine
You should see output similar to the follow:
docker-engine: Installed: (none) Candidate: 1.11.1-0~xenial Version table: 1.11.1-0~xenial 500 500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages 1.11.0-0~xenial 500 500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages
docker-engine is not installed, but the candidate for installation is from the Docker repository for Ubuntu 16.04. The
docker-engine version number might be different.
Finally, install Docker:
sudo apt-get install -y docker-engine
Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it’s running:
sudo systemctl status docker
The output should be similar to the following, showing that the service is active and running:
● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2016-05-01 06:53:52 CDT; 1 weeks 3 days ago Docs: https://docs.docker.com Main PID: 749 (docker)
Installing Docker now gives you not just the Docker service (daemon) but also the
docker command line utility, or the Docker client.
Hope you found that useful and thanks to Digital Ocean community for the resources. And for the next tutorial we will explore how to use the
