📣 Docker 🐬 basics for beginners


🖥 Let's learn how we can develop, deploy and run applications easily with Docker!

➡️If you Google Docker, you will find that Docker is a software platform that uses an OS-level virtualization to create self-contained containers.
➡️You may have created multiple Virtual Machines with Oracle VM or Vagrant before. Docker is something like that (but better, but more about that later).
➡️With Docker, we select an image (think about Docker images as recipes) and download it. Then, we create an instance of that image or container, pretty similar to a Virtual Machine.

🛡 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 𝗣𝗼𝗱 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗔𝗱𝗺𝗶𝘀𝘀𝗶𝗼𝗻 🛡

➡️ Within Kubernetes, containerized applications are managed as logical units called 𝐏𝐨𝐝𝐬. In any deployment environment, these 𝐏𝐨𝐝𝐬' security is vital. Kubernetes provides various security controls, such as 𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐒𝐭𝐚𝐧𝐝𝐚𝐫𝐝𝐬 (𝐏𝐒𝐒) and 𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐝𝐦𝐢𝐬𝐬𝐢𝐨𝐧 (𝐏𝐒𝐀), to efficiently manage the permissions and capabilities of Pods. These controls ensure that Pods operate with the minimum required access. This approach minimizes the risk of a compromised Pod affecting other resources.

➡️ While 𝐏𝐨𝐝𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲𝐏𝐨𝐥𝐢𝐜𝐲 served its purpose, the new controls offer a more streamlined and accessible approach to enforcing security policies on Pods. 𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐝𝐦𝐢𝐬𝐬𝐢𝐨𝐧 introduces predefined security contexts and customization capabilities, enhancing flexibility, control, and ease of use.Understanding the significance of Pod security is fundamental to managing and operating Kubernetes clusters effectively and securely.

➡️ 𝗨𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴 𝗣𝗼𝗱 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗔𝗱𝗺𝗶𝘀𝘀𝗶𝗼𝗻
𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐝𝐦𝐢𝐬𝐬𝐢𝐨𝐧 is a feature introduced in Kubernetes to enforce clear and consistent isolation levels for Pods. It builds upon the Kubernetes Pod Security Standards, guidelines that govern how Pods behave and interact with other resources.

By applying security restrictions at the Kubernetes namespace level when Pods are created, 𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐝𝐦𝐢𝐬𝐬𝐢𝐨𝐧 provides a mechanism to ensure that Pods operate with only the necessary permissions. This enhances security and aligns with broader best practices in software deployment, minimizing the risk of unauthorized access or compromised resources.
The importance of 𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐝𝐦𝐢𝐬𝐬𝐢𝐨𝐧 lies in its ability to make security a fundamental and integral part of the Kubernetes ecosystem. Rather than treating security as an afterthought, 𝐏𝐨𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐝𝐦𝐢𝐬𝐬𝐢𝐨𝐧 ensures that it is part of the design and operation of every Pod.

➡️ 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲𝘀 𝗯𝗲𝘁𝘄𝗲𝗲𝗻 𝗣𝗼𝗱 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗔𝗱𝗺𝗶𝘀𝘀𝗶𝗼𝗻 𝗮𝗻𝗱 𝘁𝗵𝗲 𝗱𝗲𝗽𝗿𝗲𝗰𝗮𝘁𝗲𝗱 𝗣𝗼𝗱𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆𝗣𝗼𝗹𝗶𝗰𝘆
Kubernetes version 1.21 significantly shifted from PodSecurityPolicy (PSP) to Pod Security Admission. While PSP intended to enforce security settings on Pods, it was deprecated due to its complexity and lack of flexibility.
Pod Security Admission introduces a more streamlined approach, utilizing labels to define admission control modes at the namespace level. These labels dictate the action the control plane takes if a potential violation is detected, such as rejection (enforce), audit annotation (audit), or user-facing warning (warn).

⚙️ Terraform with Azure DevOps CI/CD Pipelines 👾


In this article, we will look at how to run Terraform in an Azure DevOps pipeline, step-by-step. We will go from the start of the process showing how to create an Azure DevOps instance and project, how to setup Terraform in Azure DevOps, and how to create Terraform configuration files for the infrastructure and pipelines using YAML, sharing some examples and best practices along the way.

When it comes to writing a Dockerfile 🐬, there are a few best practices to keep in mind:

1️⃣. Use official base images: Starting with an official base image from Docker Hub is recommended. These images are maintained and regularly updated by the community, ensuring stability and security.

2️⃣. Keep it minimal: Only include the necessary dependencies and files in your Docker image. This helps keep the image size small and improves build times.

3️⃣. Use explicit versioning: Specify the versions of the software and libraries you're using in your Dockerfile. This helps ensure consistency and avoids unexpected changes in behavior.

4️⃣. Leverage caching: Docker builds can be faster by leveraging Docker's layer caching mechanism. Place frequently changing instructions towards the end of your Dockerfile to avoid invalidating the cache unnecessarily.

5️⃣. Separate build and runtime stages: If possible, split your Dockerfile into separate stages for building and running the application. This can help reduce the size of the final image and improve security.

6️⃣. Use COPY instead of ADD: When copying files into your Docker image, prefer the COPY instruction over the ADD instruction. COPY is simpler and doesn't have the additional functionality of ADD, which can lead to unexpected behavior.

7️⃣. Clean up after each step: To minimize the size of your Docker image, remove unnecessary files and cleanup after each step in your Dockerfile. This can be done using the RUN instruction with appropriate cleanup commands.

💎 DevOps vs DevSecOps

Think of a software development team working together to make a product quickly and smoothly. That's DevOps. Now, imagine adding someone to the team who makes sure the product is safe from hackers and other dangers. That's DevSecOps.

🔸 DevOps: In software development, DevOps is like a team of people who work together with development and operations team to make software releases fast and work without any problems. They use tools and teamwork to make sure everything runs smoothly.

🔸 DevSecOps: DevSecOps builds upon DevOps principles by integrating security practices into every stage of the software lifecycle. It proactively addresses security concerns by incorporating security tools and processes, ensuring that vulnerabilities are identified and remediated early in development.

In Summary: DevOps makes software quickly and smoothly, while DevSecOps adds security to make sure the software is safe from cyber threats. Both are important for making good quality software.
