Installing Docker Engine 19.03 on Raspberry Pi 3 in 2 Minutes

Estimated Reading Time: 6 minutes

Docker is officially supported both on Raspberry Pi 3 and 4. Installing Docker is just a matter of single-liner command. All you need to do is a simple curl command:

curl -sSL https://get.docker.com/ | sh

to get Docker binaries installed flawlessly. Isn’t it damn simple?

Raspbian is a free operating system based on Debian optimized for the Raspberry Pi hardware. An operating system is the set of basic programs and utilities that make your Raspberry Pi run. However, Raspbian provides more than a pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your Raspberry Pi.

Docker today support the latest Raspbian Buster release. If you really want to play around with stable release of Docker for Raspbian Buster, then head over to this link.

Under this blog post, I will showcase how to install latest Docker Engine 19.03.1 on Raspbian OS Buster release flawlessly.

Prerequisite

  • Flash Raspbian OS on SD card

If you are in Mac, you might need to install Etcher tool. If on Windows, install SDFormatter to format SD card as well as Win32installer to flash Raspbian ISO image onto the SD card. You will need SD card reader to achieve this.

Booting up Raspbian OS

Just use the same charger which you use for your mobile to power on Raspberry Pi box. Connect HDMI port to your TV or display. Let it boot up.

The default username is pi and password is raspberry.

Enable SSH to perform remote login

To login via your laptop, you need to allow SSH service running. You can verify IP address command via ifconfig command.

Unboxing 3.5” Touch Screen RPi LCD for Raspberry Pi 3 in 2 Minutes

Estimated Reading Time: 3 minutes
A 3.5” LCD mounted directly into Raspberry Pi showing Docker Installables

If you have ever conducted Docker on Raspberry Pi workshop during the Meetup event, you surely understand the pain in bringing up working infrastructure. Especially when you are dependent upon WiFi network of the hosting company, it becomes difficult as in every new Meetup venue, you need to plug your HDMI-equipped monitor into the Raspberry Pi using a standard HDMI cable and then configuring IP address so as to get it discovered over findPi Mobile application.

The HDMI cable is one of the most important piece of equipment that you can use with your Raspberry Pi, which means that in theory you can connect it to a wide selection of televisions and even modern desktop computer monitors. But in case HDMI cable is not available, then you might have to rely on alternative way of getting display device to configure Pi systems.

RPi LCD comes to the rescue..

Raspberry Pi Touchscreen LCD provides you with the ability to create a standalone device that can be utilized as a custom tablet or an all-in-one interactive interface for a future project using your Raspberry Pi 3. This small 3.5-inch touch screen module is designed especially for Raspberry Pi, using the latest Linux Core system. This is ideal for DIY anywhere, anytime and does not require any separate power source or case to hold it. The module sits right on top of Pi and an ideal alternative solution for HDMI monitors. The screen also comes with a stylus to interact with the small screen.

Features:

  1. Designed for Raspberry Pi, an ideal alternative solution for HDMI monitor
  2. Supports all revision of Raspberry Pi (directly-pluggable models)
  3. Works with Raspbian/Ubuntu directly
  4. Comes with full set of screws and nuts for assembly
  5. 320×480 resolution, better display
  6. Lightweight and easy to install

Preparing Your Setup

To configure RPi LCD for Raspberry Pi, first login to your Pi system:

Visit https://www.waveshare.com/wiki/Main_Page and search for “RPi LCD” for your specific model which you have purchased. In my case, it was 3.5” LCD monitor, hence I went ahead and selected it to open the below link:

https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(B)

Run the below command:

sudo raspi-config

Select Boot Options > Desktop Autologin

As soon as you select Desktop Autologin, it will ask to select “Finish” and the system will go for reboot.

Clone the Repository

git clone https://github.com/waveshare/LCD-show.git

Execute the script

./LCD35B-show

After system rebooting, the RPi LCD is ready to use.

In my next blog post, I will showcase how I used 3.5” LCD screen directly mounted over Celestron Telescope to view moon’s surface flawlessly.
