Reusable Helm charts for different application deployment patterns at JupiterOne

Installing the Chart

To configure the jupiterone-apps helm repo, you'll want to run the following commands:

helm repo add jupiterone-apps https://jupiterone.github.io/apps-helm-charts
helm repo update

Installation Example

To install the chart with the release name: jupiterone-persister-example in namespace jupiterone-persister-example with custom configuration specified, run the following commands:

helm install jupiterone-persister-example jupiterone-apps/application --create-namespace --namespace jupiterone-persister-example --values ./values.yaml 

Uninstallation Example

To uninstall the chart:

helm delete <name-of-the-chart> -n namespace

Unit Tests

Suites live under charts/application/tests/, one file per template area, and run with the helm-unittest plugin. Fixtures shared with the PR render/Pluto/kubeconform loop live under charts/application/tests/fixtures/.

helm plugin list | grep -q unittest || helm plugin install https://github.com/helm-unittest/helm-unittest --version v1.0.3
helm unittest charts/application

Naming convention for ConfigMap and Secrets

Naming convention of type ConfigMap and Secrets is as follows: {{ template "application.name" $ }}-{{ $nameSuffix }}

• {{ template "application.name" }} is a helper function that outputs .Values.applicationName if exist else return chart name as output
• nameSuffix is the each key in secret.files and configMap.files

For example, if we have the following values file:

applicationName: helloworld # {{ template "application.name" $ }}

configMap:
  files:
    config: # {{ $nameSuffix }}
      key: value

then the configmap name will be helloworld-config

Consuming environment variable in application chart

In order to use environment variables in a deployment or cronjob, you will have to provide environment variable in key/value pair in env value. where key being environment variable key and value varies in different scenarios

• For simple key/value environment variable, just provide value: <value>

   env:
      KEY:
        value: MY_VALUE
  

• To get environement variable value from ConfigMap

  Suppose we have configmap created from applicaion chart

  applicationName: my-application
  configMap:
    enabled: true
    files:
      application-config:
        LOG: DEBUG
        VERBOSE: v1
  

  To get environment variable value from above created configmap, we will need to add following

  env:
   APP_LOG_LEVEL:
    valueFrom:
      configMapKeyRef:
        name: my-application-appication-config
        key: LOG
  

  To get all environment variables key/values from ConfigMap, where configmap key being key of environment variable and value being value

    envFrom:
     application-config-env:
       type: configmap
       nameSuffix: application-config
  

  you can either provide nameSuffix which means name added after prefix <applicationName>- or static name with name of configmap.

• To get environment variable value from Secret

  Suppose we have secret created from application chart

   applicationName: my-application
   secret:
     enabled: true
     files:
        db-credentials:
          PASSWORD: skljd#2Qer!!
          USER: postgres
  

  To get environment variable value from above created secret, we will need to add following

    env:
       KEY:
        valueFrom:
         secretKeyRef:
           name: my-application-db-credentials
           key: USER
  

  To get environement variable value from Secret, where secret key being key of environment variable and value being value

  envFrom:
    database-credentials:
       type: secret
       nameSuffix: db-credentials
  

  you can either provide nameSuffix which means name added after prefix <applicationName>- or static name with name of secret

  Note: first key after envFrom is just used to uniquely identify different objects in envFrom block. Make sure to keep it unique and relevant

Configuring probes

By default probe handler type is httpGet. You just need to override port and path as per your need.

  livenessProbe:
    enabled: true
    httpGet:
      path: '/path'
      port: 8080

In order to use exec handler, you can define field livenessProbe.exec in your values.yaml.

  livenessProbe:
    enabled: true
    exec:
      command:
        - cat
        - /tmp/healthy

To disable liveness or readiness probe, set value of enabled: to false.

  livenessProbe:
    enabled: false
