Skills Gained
- The fundamental uses of container technology and the architectural principles of how to apply containers to technical challenges.
- Create containers with both packaged solutions and custom software.
- Use the Docker and Kubernetes CLI environments to deploy solutions in local (Docker) and cluster (Kubernetes) environments.
- How stateful services – such as databases, streaming solutions , and other specialty applications – can be deployed in highly-available configurations with redundancy and service-discovery/load-balancing.
- How other components – can be used to integrate services within the Kubernetes platform.
- How Docker and technologies such as Jenkins can be used to continuously test and build containers based on changes to source code.
