## Workload
|
||||
|
||||
Workload to test application behavior while making changes on infrastructure.
|
||||
|
||||
Ingress is not included and have to be added on top.
|
||||
Feel free to customize *replicas* and *content-git-repo* in *config* folder.
|
||||
Ingress fqdn has to be configured by either:
|
||||
|
||||
Git will be displayed in an iframe with node name on top.
|
||||
* modifying file *ingress-patch-route-name.yaml*
|
||||
* using this repo as kustomize source and override inn the same way than *ingress-patch-route-name.yaml*
|
||||
|
||||
*replicas* and *content-git-repo* in *config* folder can be customized by modifying files or applying kustomize patch
|
||||
|
||||
Content git will be displayed in an iframe with node name on top. If it's empty, it will display a blank page with node name.
|
||||
|
||||
Node name is displayed on the top of the page and also in kube-node.json and on kube-node.txt
|
||||
|
||||
Thanks to https://github.com/amoldalwai/RoadFighter.git for having something fun to display.
|
||||
|
||||
## Analyse script
|
||||
|
||||
A script is given to test inngress availability.
|
||||
analyse.sh {ingress fqdn} [keep_results]
|
||||
|
||||
Option *keep_results* does not ovewrite file on startup.
|
||||
|
||||
Information is displayed in csv format: "Date (Epoch)";"Request duration";"HTTP Response code";"App availability";"Event";"Response content"
