| A backend service for delegation program where participating nodes report stats about their activity. | ||
|    | ||
|
|
||
| A Helm chart for uptime-service-backend AKA Delegation Program Backend | ||
|
|
||
| > **Note** Currently MF does not have chart repository. To install this chart i.e. with helmfile you need to reffer to it following ways: | ||
| **Homepage:** <https://docs.minaprotocol.com/node-operators/foundation-delegation-program> | ||
|
|
||
| ```console | ||
| # helmfile.yaml | ||
| <..> | ||
| releases: | ||
| - name: network_name | ||
| chart: git::ssh://[email protected]/MinaFoundation/helm-charts.git@uptime-service-backend?ref=main | ||

|
||
| ## Prerequisites | ||
|
|
||
| Before installing this Helm chart, you should have the following prerequisites: | ||
| Before using this Helm chart, you should have the following prerequisites: | ||
|
|
||
| - Access to Kubernetes cluster | ||
| - Helm installed on your local machine | ||
| - Basic knowledge of Kubernetes and Helm | ||
| - Access to https://github.com/MinaFoundation/helm-charts | ||
| - Optional: helmfile to install this chart | ||
| - Access to Kubernetes cluster (If needed contact your friendly neighbourhood DevOps engineer) | ||
| - Helm >= v3.14.3 | ||
| - (**Optional**) helmfile >= v0.162.0 to install this chart | ||
|
|
||
| ## Installation | ||
|
|
||
| To install this Helm chart, the easiest is to create a helmfile.yaml with needed values and run: | ||
| ```bash | ||
| $ helmfile template | ||
| $ helmfile apply | ||
| ``` | ||
| > Note: **examples** can be found in the repository | ||
| Or use helmfile only to generate resources and apply them with kubectl like so: | ||

|
|
||
| ```bash | ||
| $ helmfile template | kubectl -f - | ||
| ``` | ||
| helmfile template | ||
| helmfile apply | ||
| ``` | ||
|
|
||
| You can get some inspiration from helmfiles in `examples` folder. | ||
|
|
||
| Verify that the chart is deployed successfully: | ||
| Or use helmfile only to generate resources and apply them with kubectl like so: | ||
|
|
||
| ```bash | ||
| helmfile status #although kubectl probably would give better insights. | ||
| ``` | ||
| helmfile template | kubectl -f - | ||
| ``` | ||
|
|
||
| ## Configuration | ||
| Verify that the chart is deployed successfully: | ||
|
|
||
| To get all available values in cloned `helm-charts` do: | ||
| > Note: `kubectl` is a better suited tool for this | ||
| ```bash | ||
| helm show values ./uptime-service-backend | ||
| ``` | ||
| helmfile status | ||
| ``` | ||
