- What will you gain from the training?
Training objectives
During the workshops, participants will understand and learn practically how to prepare, implement, and manage applications running on Kubernetes - the most popular orchestrator for containerized applications.
In addition, attendees will acquire expertise in industry-leading methodologies for Cloud-Native application development
Participants will enhance their proficiency in utilizing Kubernetes communication tools through hands-on experience with a genuine Kubernetes cluster comprising multiple nodes.
Skills
Upon course completion, participants will possess the following competencies
- Demonstrated mastery of Kubernetes terminology
- Comprehensive understanding of Kubernetes cluster architecture
- Proficiency in executing practical directives for navigating the Kubernetes Command-Line Interface (CLI)
- Ability to proficiently prepare and deploy applications
- Competence in ensuring optimal application availability
- Skill in configuring zero-downtime upgrades
- Capacity to scale applications to requisite instance numbers
- Familiarity with delineated patterns governing the deployment of multiple containers within a pod
- Aptitude for strategizing recurring operations within the Kubernetes cluster
- Proficiency in debugging applications within the Kubernetes environment
- Ability to expose applications beyond the Kubernetes cluster
- Ability to leverage Helm charts for streamlined package management on Kubernetes
- Is this training for you?
Audience profile
The training is intended for programmers, system engineers, and architects who want to learn how to properly deploy and manage applications on Kubernetes.
Requirements
Basic command-line navigation skills are required. In case you bring your own laptop, please ensure that ssh client is installed.During the training, we will be creating/editing files on the server. Editors such as 'nano' and 'vim' will be available for editing purposes. Additionally, participants will have the option to mount a directory with tasks locally via ssh (e.g., VSCode offers suitable extensions for this purpose) and use their favorite editor from their local machine.
