Cardano-events Helm chart

Build docker images

Here we are going to build the Docker image for Cardano-events (https://github.com/tango-crypto/cardano-events)

Build the Docker image

$ cd cardano-api
$ docker build -t javiertc86/cardano-events:latest .

Push the Docker image to the repository

$ docker push javiertc86/cardano-events:latest

The next step is to install Helm. Helm is a package manager for Kubernetes that simplifies the deployment and management of applications on Kubernetes clusters.

To Install Helm on Mac and Linux follow the instructions below:

MacOS:

Install using Homebrew:

brew install helm

Linux:

Download the Helm binary:

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

For more details, refer to the official Helm Installation Guide.

Secrets encoding

Kubernetes requires secret data to be base64 encoded to ensure that it can handle arbitrary binary data in a text-based format. This encoding ensures data integrity during transport and storage.

echo -n 'your-secret-value' | base64

Example:

echo -n 'v8hlDV0yMAHHlIurYupj' | base64
# Output: djhoblRWMHlNQUhIbEl1cll1cGo=

Create secrets.yamlwith the encoded values:

apiVersion: v1
kind: Secret
metadata:
  name: cardano-events-secret
  annotations:
    meta.helm.sh/release-name: cardano-events
    meta.helm.sh/release-namespace: default
  labels:
    app.kubernetes.io/managed-by: Helm
type: Opaque
data:
  DB_USER: XXX
  DB_PWD: XXX
  OGMIOS_HOST: XXX
  KAFKA_HOST: XXX
  REDIS_HOST: XXX
  SCYLLA_CONTACT_POINTS: XXX
  DB_HOST: XXX

To view secrets:

$ kubectl get secrets

To describe secret:

$ kubectl describe secret

To view the values of the secret:

$ kubectl get secret cardano-events-secret -o yaml

Installing Helm Chart

Install the Helm chart in the default namespace

git clone https://github.com/tango-crypto/cardano-events-helm-chart.git
cd cardano-events-helm-chart
$ helm install cardano-events .

Uninstall any previous failed release

$ helm uninstall cardano-events

List running pods:

$ kubectl get pods
NAME                                                  READY   STATUS    RESTARTS   AGE
cardano-events-cardano-events-helm-chart-fd99f75bb-98cb9    1/1     Running   0          9m47s

Get logs:

$ kubectl logs -f cardano-events-cardano-events-helm-chart-fd99f75bb-98cb9
