Developing Applications with Cloud Foundry Overview:
The hands-on Developing Applications with Cloud Foundry course provides you with the concepts and hands-on experience needed to work with and deploy applications–typically written in Java/Spring-on Cloud Foundry.
You will learn and gain familiarity in the following:
- Cloud Foundry concepts:
- Applications
- Buildpacks
- Manifests
- Organizations
- Spaces
- Users
- Roles
- Domains
- Routes
- Services
- How to push applications to Cloud Foundry (various languages)
- Services
- User provided services
- Manifests
- YAML
- Environment variables
- Auto-configuration
- Logging and loggregator
- VCAP_SERVICES and VCAP_APPLICATION
The course will provide hands on experience using Pivotal Web Services, the local command line interface, and the Eclipse Cloud Foundry plugin. You will gain hands on experience in pushing apps to Cloud Foundry, accessing logs, scaling. You will learn about marketplace services and will gain experience with one or more examples. You will explore topics directly related to Spring application development in the cloud, such as Auto-configuration and Spring Cloud.
Who Should Attend:
- Application developers seeking introductory understanding of Cloud Foundry and hands-on experience using it to deploy, manage, and scale applications.
Developing Applications with Cloud Foundry Prerequisites:
Before attending this class, you must have the following:
