Installing Docker

Docker will be used to pull docker image from NGINX Plus private registry and then push it to a local registry.

Note

This already installed in your lab deployment.

Make sure you’re login to APP node then change directory to setup:

$ cd /home/ubuntu/setup

 1#!/bin/bash
 2set -x
 3sudo apt-get update
 4sudo apt-get install -y ca-certificates curl gnupg lsb-release
 5
 6sudo mkdir -p /etc/apt/keyrings
 7curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
 8echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 9
10sudo apt-get update
11sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
12
13sudo addgroup ubuntu docker
14sudo su ubuntu

Let’s execute the script:

$ bash docker.sh

At this point, Docker should be successfully installed & ready to use.
