Provider Attributes and Pricing Adjustments

Attribute Adjustments

• Conduct the steps in this section on the Kubernetes control plane from which the provider was configured in prior steps

• Adjust the following key-values pairs as necessary within the provider-storage.yaml file created below:

  • Update the values of the capabilities/storage/2/class key to the correct class type (I.e. beta2). Reference the Storage Class Types doc section for additional details.

  • Update the region value from current us-west to an appropriate value such as us-east OR eu-west

• Ensure that necessary environment variables are in place prior to issuing

Caveat on Attributes Updates in Active Leases

• If your provider has active leases, attributes that were used during the creation of those leases cannot be updated

• Example - if a lease was created and is active on your provider with key=region and value=us-east- it would not be possible to update the region attribute without closing those active leases prior

Helm Chart Update

cd ~

helm repo update

Capture and Edit provider.yaml File

• In this section we will capture the current provider settings and add necessary persistent storage elements

• NOTE - the bidpricestoragescale setting in the provider.yaml file will be ignored if the bid pricing script is used.

Capture Current Provider Settings and Write to File

cd ~

helm -n nexqloud-services get values nexqloud-provider > provider.yaml

Update provider.yaml File With Persistent Storage Settings

• Open the provider.yaml file with your favorite editor (I.e. vi or vim) and add the following

attributes:
<keep the existing ones and add the following ones:>
  - key: capabilities/storage/1/class
    value: beta2             # set your storage class here: beta1, beta2 or beta3!
  - key: capabilities/storage/1/persistent
    value: true

And add this attribute if you are not using the bid pricing script:

bidpricestoragescale: "0.00016,beta2=0.00016" # set your storage class here: beta1, beta2 or beta3!

Finalized provider.yaml File

• Post additions discussed above, your provider.yaml file should look something like this:

---
from: "$ACCOUNT_ADDRESS"
key: "$(cat ~/key.pem | openssl base64 -A)"
keysecret: "$(echo $KEY_PASSWORD | openssl base64 -A)"
domain: "$DOMAIN"
node: "$NODE"
withdrawalperiod: 24h
attributes:
  - key: region
    value: "<YOUR REGION>"   # set your region here, e.g. "us-west"
  - key: host
    value: nexqloud
  - key: tier
    value: community
  - key: organization
    value: "<YOUR ORG>"      # set your organization name here
  - key: capabilities/storage/1/class
    value: beta2             # set your storage class here: beta1, beta2 or beta3!
  - key: capabilities/storage/1/persistent
    value: true

bidpricestoragescale: "0.00016,beta2=0.00016" # set your storage class here: beta1, beta2 or beta3!

Upgrade the Helm Install

# Make sure you have "provider.yaml" previously created!
helm upgrade --install nexqloud-provider nexqloud/provider -n nexqloud-services -f provider.yaml

Expected/Example Output

NAME: nexqloud-provider
LAST DEPLOYED: Wed May 11 13:45:56 2022
NAMESPACE: nexqloud-services
STATUS: deployed
REVISION: 1
TEST SUITE: None

Verify Provider Settings

• Issue the following command to verify values applied by Helm

helm -n nexqloud-services get values nexqloud-provider

Example/Expected Output

helm -n nexqloud-services get values nexqloud-provider

USER-SUPPLIED VALUES:
attributes:
- key: region
  value: europe
- key: host
  value: nexqloud
- key: tier
...
...
bidpricestoragescale: "0.00016"
domain: REDACTED
from: nexqloud1REDACTED
image:
  tag: 0.1.0
...

Provider Status

• Note - the Helm upgrade will spawn a new provider pod

• Possible the prior provider pod may show with a status of deleting on initial view and then would eventually disappear from output

kubectl get pods -n nexqloud-services

Expected/Example Output

root@node1:~/helm-charts/charts# kubectl get pods -n nexqloud-services

NAME                                 READY   STATUS    RESTARTS   AGE
nexqloud-provider-6bf9986cdc-btvlg      1/1     Running   0          3m13s
