Docker Workshop

One Day workshop on understanding Docker to package applications into containers—standardized executable components combining application source code with the operating system.

Prerequisite

Linux machine with following packages installed

Install Ubuntu 22.04 LTS from here
Install Git from your terminal by running following commands
- ```
sudo apt-get update
```
- ```
sudo apt-get install git
```
Verify the installation was successful by typing
- ```
git --version
```

GitHub account

If you don't have the account on github then create an account on GitHub
Configure SSH key by following the below steps
- Generating a new SSH key
- Adding your SSH key to the ssh-agent
- To list all contents of ssh folder
```
ls -al ~/.ssh
```
- To instal xclip
```
sudo apt install xclip
```
- Copy ssh key
```
xclip -sel clip < ~/.ssh/id_ed25519.pub
```
- Adding a new SSH key to your Github account
Create a new work directory named WORKSHOP inside the /home directory, by running following command in the terminal.
- ```
mkdir WORKSHOP
```
Fork the current repository.
Clone your forked repository inside the WORKSHOP directory.

Info: You can refer this guide to understand how to fork and clone

Docker instalation

To install docker follow the below mentioned steps.
1. Set up the repository
2. Install Docker Engine
Configure docker to run without sudo.
1. Manage Docker as a non-root user
Install Docker-compose by running the follwing command:
- The following command will download the 2.16.0 release and save the executable file at /usr/local/bin/docker-compose, which will make this software globally accessible as docker-compose:
```
sudo curl -SL https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
```
- Set the correct permissions so that the docker-compose command is executable:
```
sudo chmod +x /usr/local/bin/docker-compose
```
- To verify that the installation was successful, you can run:
```
docker-compose --version
```
  You’ll see output similar to this:
```
Output
docker-compose version 2.16.0, build 5becea4c
```
  Docker Compose is now successfully installed on your system.

Download the follwing docker images to your local machine

docker pull node:18.15.0-alpine3.17

Verify the image is pulled into your local machine
```
 docker run --rm -ti node:18.15.0-alpine3.17 node -v
```
Output: v18.15.0

docker pull postgres:14-alpine

Verify the image

docker run --rm -ti postgres:14-alpine  psql -V

Output: psql (PostgreSQL) 14.5

```
docker pull nginx:1.23.0-alpine
```

VS Code setup

What will you learn by the end of this workshop?
