Study Notes
Containerization and Kubernetes
- Containerization using Docker has made running apps simpler, but as projects grow in size and complexity, managing them with Docker can become a real pain.
- Kubernetes (k8s) is a powerful platform for container orchestration that can solve many problems, but it introduces a new level of complexity.
Docker Pros and Cons
- Docker is great for running containers on a single host, allowing multiple isolated applications on a single machine.
- Docker has many free and open-source tools, such as Docker Compose and Portainer, that enhance workflow and management.
- However, Docker can be problematic for smaller home labs using Raspberry Pi's or Intel NUCs, especially when adding multiple servers, as it requires managing conflicts and resources for all containers.
Kubernetes Advantages
- Kubernetes provides features to manage deployment, storage, networking, and secrets, making it a more versatile and powerful tool than Docker.
- Kubernetes allows for high availability, replication, and scaling of containers, making it suitable for organizations looking to deploy containers at scale.
- Kubernetes is not just for large organizations; it can also be used in home labs to manage resources and provide high availability.
Kubernetes Challenges
- Getting started with Kubernetes is not as difficult as people believe, with tools like k3s and microk8s making it easy to set up a high-available cluster.
- However, Kubernetes has a steep learning curve due to its complex architecture, many moving parts, and required knowledge of networking, security, and storage.
- Troubleshooting issues in Kubernetes can be difficult, especially for those new to the technology.
Real-World Experience with Kubernetes
- The author has experienced many problems with Kubernetes, including replication, storage, and networking issues.
- Despite the challenges, the author believes Kubernetes has a place in home labs, especially as projects grow in size and complexity.
- The author continues to use Docker for simple applications but uses Kubernetes for more complex projects that require high availability and replication.
Additional Kubernetes Tools and Features
- Argo CD can be used to deploy applications in Kubernetes, providing automation and simplification.
- Helm is another tool that can be used to deploy complex applications in Kubernetes with versioning support.
- Other tools and features in Kubernetes include search manager for SSL certificates, traffic, and load balancing, as well as storage options like persistent volumes and claims.
Takeaways
- Kubernetes is a powerful tool for container orchestration, but it requires a significant investment of time to learn and master.
- Docker is suitable for simple applications, but as projects grow in complexity, Kubernetes can provide the necessary tools and features to manage resources and provide high availability.
- Gaining hands-on experience with Kubernetes in a home lab can develop valuable skills that are in high demand in the IT industry.
