🚀 Terraform Commands for DevOps Engineers 🌍

Mastering Terraform can greatly enhance your infrastructure management. Here’s a quick reference to essential Terraform commands:

1️⃣ terraform init - Initialize a Terraform working directory.

2️⃣ terraform validate - Check the configuration for syntax errors.

3️⃣ terraform plan - Generate and show an execution plan.

4️⃣ terraform apply - Apply the changes required to reach the desired state.

5️⃣ terraform destroy - Destroy the Terraform-managed infrastructure.

6️⃣ terraform show - Show the current state or a saved plan.

7️⃣ terraform output - Extract the value of an output variable from the state file.

8️⃣ terraform state - Advanced state management commands:
- terraform state list - List resources in the state.
- terraform state show - Show a resource in the state.
- terraform state rm - Remove a resource from the state.

9️⃣ terraform fmt - Reformat configuration files to the canonical format.

1️⃣0️⃣ terraform taint - Manually mark a resource for recreation.

1️⃣1️⃣ terraform untaint - Manually unmark a resource as tainted.

1️⃣2️⃣ terraform import - Import existing infrastructure into your Terraform state.

1️⃣3️⃣ terraform refresh - Update the state file with the real infrastructure.

📘 Helpful Links:
- Terraform Documentation: https://www.terraform.io/docs/index.html
- Terraform Best Practices: https://www.terraform-best-practices.com

Basic 📱 Git Flow in DevOps ♾ CI-CD!

1️⃣. Developer Creates Feature Branch: The developer creates a new feature branch and is used to work on a new feature or a specific task.

2️⃣. Developer Writes Code: The developer writes the necessary code for the feature in their local development environment.

3️⃣. Developer Commits Changes: Once the developer is satisfied with the changes, they commit the changes to the feature branch in the local Git repository.

4️⃣. Developer Creates Pull Request: The developer pushes the committed changes by creating a pull request to merge the feature branch into the main branch.

5️⃣. Code Review by Team: The pull request initiates a code review process where team members review the changes.

6️⃣. Approval of Pull Request: After addressing any feedback and making necessary adjustments, the pull request is approved by the reviewers.

7️⃣. Merge to Main Branch: The approved pull request is merged into the main branch of the Git repository.

8️⃣. Triggers CI/CD Pipeline: This automation ensures that the changes are continuously integrated and deployed.

9️⃣. Then we follow the procedure for building and testing the code, deploying to staging env. Once the tests in the staging environment pass, a manual approval is required to deploy the changes to the production environment. Once the code is deployed to production env, the prod env is monitored using Prometheus to track the performance and health of the application. The collected metrics are visualized using Grafana. Finally alerts are configured.

🐧 The Linux file system isn't just a bunch of folders - it's the organizational bedrock of your entire system.

Mastering it can take your tech career to the next level. Here's why:
⏩ 𝗞𝗲𝘆 𝗗𝗶𝗿𝗲𝗰𝘁𝗼𝗿𝗶𝗲𝘀 & 𝗧𝗵𝗲𝗶𝗿 𝗥𝗼𝗹𝗲𝘀:
➡️ Root (/): The central hub, connecting everything.
➡️ Bin & Sbin: Essential tools for basic system operation and advanced tasks.
➡️ Etc: Configuration files that make your system tick.
➡️ Home: Your personal storage space for files and documents.
➡️ Var: Holds dynamic data like logs and emails, constantly changing.
➡️ Usr: A vast library of applications, libraries, and data used by the system.
➡️ Lib & Opt: Support files for other programs and optional software.
➡️ Tmp: Temporary storage for the system's ongoing work.
➡️ Boot & Dev: Responsible for booting the system and interacting with hardware.
➡️ Proc & Root: Special directories for system information and the root user.
➡️ Run & Srv: Temporary files for running processes and data for system services.
➡️ Sys & Mnt: Virtual system info and mount points for external storage.
➡️ Media: Where removable media like CDs and cameras connect.

⏩ 𝗪𝗵𝘆 𝗦𝗵𝗼𝘂𝗹𝗱 𝗬𝗼𝘂 𝗖𝗮𝗿𝗲?
Linux powers countless technologies, and familiarity with its file system gives you an edge in various tech fields:
✔️ Software Engineering: Navigating codebases and system files with ease.
✔️ DevOps: Automating tasks and managing infrastructure efficiently.
✔️ Data Engineering: Working with data stored on Linux systems.
✔️ AI: Understanding where data and resources are located.
✔️ System Administration: Maintaining and troubleshooting Linux systems like a pro.

⏩ 𝗞𝗻𝗼𝘄𝗶𝗻𝗴 𝘁𝗵𝗲 𝗳𝗶𝗹𝗲 𝘀𝘆𝘀𝘁𝗲𝗺:
🔶 Saves you time by finding files quickly.
🔶 Empowers you to troubleshoot issues effectively.
🔶 Makes you a valuable asset to any team.

⏩ 𝗚𝗼 𝗕𝗲𝘆𝗼𝗻𝗱 𝘁𝗵𝗲 𝗕𝗮𝘀𝗶𝗰𝘀:
This is just a starting point. Dive deeper, explore each directory, and unlock your tech potential. Share your questions in the comments, and let's learn together!

⚡ 𝗠𝗮𝘀𝘁𝗲𝗿𝗶𝗻𝗴 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝗗𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁 𝗦𝘁𝗿𝗮𝘁𝗲𝗴𝗶𝗲𝘀! ⚡

Kubernetes offers a variety of deployment strategies to ensure smooth and efficient application updates. Here are some of the key strategies every DevOps engineer should know:

1️⃣ 𝑹𝒆𝒄𝒓𝒆𝒂𝒕𝒆 𝑫𝒆𝒑𝒍𝒐𝒚𝒎𝒆𝒏𝒕
Process: Terminates all old pods before creating new ones.
Use Case: Suitable for stateful applications where downtime is acceptable.

2️⃣ 𝑹𝒐𝒍𝒍𝒊𝒏𝒈 𝑼𝒑𝒅𝒂𝒕𝒆
Process: Gradually replaces old pods with new ones.
Use Case: Ideal for stateless applications to ensure zero downtime during updates.

3️⃣ 𝑩𝒍𝒖𝒆-𝑮𝒓𝒆𝒆𝒏 𝑫𝒆𝒑𝒍𝒐𝒚𝒎𝒆𝒏𝒕
Process: Runs two identical environments (blue and green) and switches traffic from blue to green.
Use Case: Ensures quick rollback if issues are detected, perfect for critical applications.

4️⃣ 𝑪𝒂𝒏𝒂𝒓𝒚 𝑫𝒆𝒑𝒍𝒐𝒚𝒎𝒆𝒏𝒕
Process: Releases new versions to a small subset of users before full rollout.
Use Case: Mitigates risk by testing updates on a limited scale.

🔖What is Kubernetes, and how does it work?

Kubernetes (K8s) is an open-source platform designed to manage containerized applications at scale.

It automates deployment, scaling, and management, making it easier to handle complex, distributed applications in dynamic environments.

‼️𝗦𝗼 𝗵𝗼𝘄 𝗱𝗼𝗲𝘀 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝘄𝗼𝗿𝗸?

A Kubernetes 𝗰𝗹𝘂𝘀𝘁𝗲𝗿 consists of a set of worker machines, called 𝗻𝗼𝗱𝗲𝘀, that run containerized applications.

The worker nodes host 𝗣𝗼𝗱𝘀, which are the components of your application workload. The 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝗽𝗹𝗮𝗻𝗲 oversees the nodes and Pods, managing deployment, scaling, and maintenance.

In production environments, the control plane is distributed across multiple servers for fault-tolerance and high availability.

‼️𝗞𝟴𝘀 𝗵𝗮𝘀 𝗺𝗮𝗻𝘆 𝗰𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀, 𝘀𝗼𝗺𝗲 𝗼𝗳 𝘁𝗵𝗲 𝗺𝗼𝘀𝘁 𝗸𝗲𝘆 𝗶𝗻𝗰𝗹𝘂𝗱𝗲:

🔸 Node: machines (physical or virtual) where Kubernetes runs workloads

🔸 Pod: the smallest deployable unit, encapsulating one or more containers

🔸 Service: abstracts and exposes Pods via a stable IP or DNS, enabling communication

🔸 Control plane: the brain of the cluster, consisting of key components like:

🔸 API server: the main entry point for all cluster management requests

🔸 Scheduler: assigns Pods to Nodes based on resource availability

🔸 Controller manager: runs controllers to maintain the desired state of the cluster

🔸 etcd: stores cluster configuration and state as a distributed key-value store

ℹ️ 𝗖𝗼𝗿𝗲 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀:

🔹 Auto-scaling: adjusts workloads dynamically

🔹 Self-healing: detects and replaces failed containers

🔹 Load balancing: distributes traffic to maintain reliability

🔹 Multi-cloud support: works seamlessly across environments

🔹 Declarative configurations: use YAML/JSON files to manage states

ℹ️ 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝗶𝘀 𝗰𝗼𝗺𝗺𝗼𝗻𝗹𝘆 𝘂𝘀𝗲𝗱 𝗶𝗻 𝗮 𝘄𝗶𝗱𝗲 𝗿𝗮𝗻𝗴𝗲 𝗼𝗳 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀. 𝗔 𝗳𝗲𝘄 𝗼𝗳 𝘁𝗵𝗲 𝗺𝗼𝘀𝘁 𝗰𝗼𝗺𝗺𝗼𝗻 𝗶𝗻𝗰𝗹𝘂𝗱𝗲:

Microservices deployment: simplifies managing and scaling containerized microservices

CI/CD pipelines: automates build, test, and deployment workflows

Cloud-native apps: powers dynamic and portable cloud-based applications

Batch processing: handles large-scale data and computational jobs efficiently

Event-driven applications: enables real-time data processing and IoT solutions

Scaling stateful applications: supports persistent storage for databases and critical workloads

Kubernetes brings scalability, reliability, and automation to containerized applications. While it has a steep learning curve and adds complexity, its benefits make it indispensable for managing modern, distributed systems.
