|
OSToy is a Node.js application that deploys to a {product-title} cluster to help explore the functionality of Kubernetes.
|
||
|
|
|
||
|
|
This application has a user interface where you can:
|
||
|
|
|
||
|
|
* Write messages to the log (stdout / stderr)
|
||
|
|
* Intentionally crash the application to view self-healing
|
||
|
|
* Toggle a liveness probe and monitor OpenShift behavior
|
||
|
|
* Read ConfigMaps, secrets, and environment variables
|
||
|
|
* Read and write files when connected to shared storage
|
||
|
|
* Check network connectivity, intra-cluster DNS, and intra-communication with the included microservice
|
||
|
|
* Increase the load to view automatic scaling of the pods by using the HPA
|
||
|
|
//* Connect to an AWS S3 bucket to read and write objects
