Basic Linux skills are essential for roles in Cloud, DevOps, Cyber, and SRE. Junior Cloud and DevOps roles are growing in the industry. It’s a good idea to practice Linux skills to make yourself more employable. During this module, you will execute commands in the terminal to create files and run scripts, so you will have many chances to practice your command line skills.

Your goal is to get to Level 30 by the end of the module. 💪 You can do this!

There is no submission step. However, to apply for some roles and some courses (like CYF+ ) you must demonstrate these skills, so it would be a good idea to learn them.

Anything else?

Here’s a ChatGPT prompt you can use to get the best, most helpful learning experience:

Please act as a friendly, warm, straightforward technical mentor. You are an experienced Site Reliability Engineer who uses the terminal regularly and understands all shell commands in bash. You can explain clearly, using English mostly at CEFR B2 level, how to execute shell commands and how to navigate Linux file systems. We will be playing The Bandit, Over the Wire, shell game together. I don’t want you to give me all the answers. I want you to walk me towards the answer, helping me to find out and learn Linux commands, explaining clearly what is happening as we go. Please answer my questions carefully and do not offer code solutions, just explain in English the approach I should take and then review the commands I suggest to you. Say okee dokee if you understand.

And remember: every time ChatGPT offers code you don’t recognise, you must ask “Is this valid” before you continue. ChatGPT makes up invalid code all the time.

Why are we doing this?

Objective

In this exercise, you will utilize a Terraform module to create a reusable configuration for S3 buckets. Additionally, you’ll implement remote state management using an S3 bucket.

Steps

1. Create a Terraform Module for S3 Buckets

   • Create a new directory named s3_module and place a new Terraform file inside it, e.g., main.tf.
   • Define the Terraform code for an S3 bucket inside this file.

2. Implement Remote State in S3

   • In your main Terraform configuration (main.tf), configure the backend for remote state using S3.

3. Initialize and Apply

   • Initialize your Terraform project.
   • Apply the configuration to create the S3 bucket using the module and configure remote state.

Validation

• Confirm that the S3 bucket was created as expected.
• Check the S3 bucket where you store the remote state to ensure that the terraform.tfstate file is present.

Research Docker Compose, its syntax and a few examples. Think how it can help you orchestrate your 3 containers for local development, and then create a docker-compose file to use this tool to automatically build, start and network your containers. Find a way to specify dependencies, to ensure that the backend start initialising only when the database is up and running.

If you want, you can experiment with running all 3 components in EC2 via Docker compose, but keep it as an experiment. Think about some advantages and disadvantages of the 2 approaches (all in a docker-compose file inside a EC2 instance vs using multiple managed services such as S3 and RDS)

Local development (bonus)

This step is a bonus one, if you completed all previous steps and are not behind on the previous weeks.

Dockerise your Frontend, and have it run locally alongside via Docker with your backend. Can you get both to work correctly at the same time?

Replicate the process for the database, and move it from your local instance to a local Docker Container (remember persistence via volumes).

In both cases, managed AWS services (S3 and RDS) give us a lot of advantages for Cloud Deployment, but lack support for local development, and Docker can help with that.

Imagine how you would automate, with a script, the process of rebuilding all 3 containers on changes, and restart/reconnect everything. Try to build it.

Dockerize CYF Hotel

The main aim of this sprint is to become familiar with Docker Concepts and be able to use it to a base level. To achieve this, we’ll keep working on our CYF Hotel.

Prep

Make sure you have completed the prep for this week and your Docker daemon is working correctly before continuing.

Docker Backend

Start working on dockerising your application backend. Create a Dockerfile, set it up for node and replicate your setup and install steps that were manual so far in there. Iterate until you get it to run successfully as a Docker Container locally. Hint: Remember port forwarding!

Once successful, upload your created Docker Image to either your DockerHub account or (advanced) AWS’s ECR.
Once done, Update your EC2 instance to now run your backend as a container. Hint: You will need to set up Docker on the VM itself for this to work

GitHub Pipelines

Once this is done and working fully, time to automate it - rework your Github Actions Workflow to test, build and upload your Docker image, and then deploy the new version to the EC2 machine.
