Deep dives
Kubernetes and Swarm for Container Orchestration
This podcast episode explores the topic of container orchestration, specifically focusing on Swarm and Kubernetes. The host emphasizes the importance of learning both orchestrators and discusses the pros and cons of using each one. The speaker mentions that the Docker Mastery course has been updated to include Kubernetes, providing comprehensive training on Docker, Compose, Swarm, and Kubernetes in a single course. The episode also highlights the upcoming conferences and workshops the host will be attending. Furthermore, it is mentioned that considering other orchestrators besides Kubernetes, such as Amazon ECS or Nomad, is important and beneficial. The speaker encourages listeners to understand various options and not blindly choose Kubernetes due to its current popularity. Finally, the speaker announces the upcoming release of Kubernetes Mastery, a course dedicated solely to Kubernetes.
Container Security and Best Practices
The podcast episode discusses various container security measures such as AppArmor, SELinux, SecComp, and Docker capabilities. The speaker emphasizes the importance of enabling SELinux and AppArmor if they are available on your system. It is mentioned that Docker automatically uses SecComp and that capabilities in Docker are still in early stages. The speaker recommends consulting the Ask Me Anything documentation for a comprehensive security list. The episode highlights the significance of implementing security measures in containers to protect against potential vulnerabilities.
Choosing the Right Cloud Provider for Containers
The podcast episode touches upon the considerations when selecting a cloud provider for container deployments. The speaker mentions popular options like AWS, Google Cloud, and DigitalOcean. They point out that specific preferences often already exist within organizations and vary based on requirements. The speaker highlights that companies tend to gravitate towards Azure or AWS for container deployments, while DigitalOcean is popular among developers. However, the ultimate choice depends on specific needs and a company's existing infrastructure and expertise.
Load Balancing with Traffic
The episode briefly mentions traffic as a recommended load balancer for containers. The speaker expresses their preference for traffic due to its suitability for container environments and auto SSL capability. They mention that traffic is designed specifically for containers, simplifying load balancing and enabling automatic SSL certificates. While other load balancer options like HAProxy or Nginx are stable, traffic is seen as easier to use, particularly for those focusing on container-based applications.
Getting Started with Docker Swarm and Kubernetes
The episode highlights the benefits of using Docker Swarm and Kubernetes for container orchestration. It suggests starting with Docker Swarm for those who are new to containers, emphasizing its ease of use and compatibility with Docker. The speaker mentions that Docker Mastery course provides an extensive guide to using Swarm. Additionally, the episode announces the upcoming launch of Kubernetes Mastery, a comprehensive course dedicated solely to Kubernetes. It indicates that using both orchestrators and understanding their differences allows for better decision-making when choosing the appropriate tool based on project requirements.
In this episode from my YouTube Live show, I talk more about Swarm and Kubernetes for Container Orchestration, and how I believe you should learn both. I answer questions from my Live YouTube audience and share some pros and cons of using each of the orchestrators. I recently updated my Docker Mastery course to include Kubernetes, so now you can get the best training on Docker, Compose, Swarm, and Kubernetes in a single course. Docker Mastery now includes over 15 hours of video. You can get discount coupons for all my courses at bret.show/courses
