Description
With the number ONE Docker + Kubernetes mega-course, get ready for the future of Docker. We're glad you're here.
This is the most comprehensive and current course available for understanding and using containers from start to finish, from development and testing through server deployments and production. taught by a DevOps consultant and award-winning Docker Captain.
Just got introduced to Docker? Perfect. This lesson begins by presuming that you are unfamiliar with containers.
Or: Do you now use Docker and have to cope with practical issues? You have my support! Check out my production articles on topics like Swarm, Kubernetes, logging, rolling updates, and more.
Among the many fun activities you'll do in this course are:
- While it is being served up in a container, edit web code on your computer.
- Secure your apps with private networks that only open up the required ports.
- In the cloud, establish a 3-node Swarm cluster.
- Install Kubernetes and become familiar with the top server cluster tools.
- For integrated load balancing in your cluster, use virtual IPs.
- Boost your Dockerfiles for quicker builds and smaller deployments.
- Create and distribute your own unique application images
What is Docker?
Using OS-level virtualization, Docker's platform as a service offerings distribute software in packages known as containers. There are free and premium tiers for the service.
The Docker Engine is the name of the programme that runs the containers. Docker, Inc. created it, and it originally debuted in 2013.
An open-source container orchestration system called Kubernetes is used to automate the management, scaling, and deployment of software.
Kubernetes was first created by Google, but the Cloud Native Computing Foundation now looks after the project. The Greek word for "helmsman" or "pilot" is where the term Kubernetes comes from.
Google originally created Kubernetes as a portable, open-source, cloud-native infrastructure platform to manage their clusters.
It automates the scaling, deployment, and maintenance of containerized applications because it is a container orchestration tool. Compared to Docker Swarm, Kubernetes has a more intricate cluster topology.
Why should you learn Docker?
| Efficient Development | Docker allows you to standardize your development environments, which speeds up development and guarantees that your code will function the same across all platforms. |
| Portability | Docker allows apps and their dependencies to be packaged into containers that can then be moved effortlessly between development and production environments. |
| Scalability | Using Docker's containerized approach, you can easily scale apps to meet the ever-evolving demands of your business. |
| Isolation and Security | Because of the segregation provided by containers, programs can function safely and reliably without affecting one another. |
| Faster Deployment | Docker simplifies application delivery by reducing time spent on deployment. |
| Version Control | Docker images are like blueprints for your app, except they are versioned so you can easily roll back or switch between different versions. |
| Collaboration | Docker promotes teamwork by standardizing development and testing environments. |
| DevOps Integration | Docker was developed for use with today's DevOps workflows without causing any disruption. |
| Cloud Compatibility | Large cloud service providers back Docker, making it easier to move apps to the cloud. |
| Future-Proof Skill | Learning Docker is becoming increasingly important for developers and IT workers as the use of containers becomes more widespread. |
