Added train-ticket.

[JacksonArthurClark]

Be sure to put our train-ticket in TargetMicroservices for testing.

[yinfangchen]

How does Helm find the chart of the train-ticket? (same question for the flight-tickect)
It seems that I do not see the train-ticket repo/chart path in this commit.

[yinfangchen]

I tried it in the CloudLab and validated that the path cannot be found : )

(aiopslab-py3.11) yinfang@node0:~/AIOpsLab$ python3 -m aiopslab.service.apps.train_ticket

[JacksonArthurClark]

Did you clone train ticket into TargetMicroservices?

[yinfangchen]

Which Train-Ticket shall I put? The train-ticket in https://github.com/xlab-uiuc/agent-ops-benchmarks?
I thought you might have some customized version somewhere.

[JacksonArthurClark]

@yinfangchen the xlab fork: https://github.com/xlab-uiuc/train-ticket

[yinfangchen]

OKay, got it. Let me try.

Did you encounter this? It seems that there is no PV for the nacosdb.

[JacksonArthurClark]

@yinfangchen

kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml
kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

Similar setup with openebs that we use for other services.

[yinfangchen]

Shall I run these two commands?

kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml
kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

[JacksonArthurClark]

@yinfangchen Yes, that will set up openebs so the PVCs will work.

[yinfangchen]

@JacksonArthurClark, great I am able to see the running train-ticket on my side now! Shall we

1. put the train-ticket (submodule?) in the correct position
2. embed the two lines of kubectl script into the code if this is a universal problem

[JacksonArthurClark]

@yinfangchen Let's keep it as a submodule
