Application

Generic helm chart for applications which are:

  • stateless
  • create only namespace scoped resources (e.g. it doesn't need CRB - cluster role bindings)
  • don't need privileged containers
  • don't call the underlying Kubernetes API or use the underlying etcd as a database by defining custom resources
  • run either as deployment or cronjob

Installing the Chart

To install the chart with the release name my-application in namespace test:

helm repo add stakater https://stakater.github.io/stakater-charts
helm repo update
helm install my-application stakater/application --namespace test

Uninstall the Chart

To uninstall the chart:

helm delete <name-of-the-chart>

Parameters

Name Description Value

namespaceOverride Override default release namespace with a custom value application
labels.group Label to define application group com.stakater.platform

Naming convention for ConfigMap, Secret, SealedSecret and ExternalSecret

Name format of ConfigMap, Secret, SealedSecret and ExternalSecret is {{ template "application.name" $ }}-{{ $nameSuffix }} then:

  • {{ 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,configMap.files, sealedSecret.files and externalSecret.files

For example if we have 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 variable in 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

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

  livenessProbe:
    enabled: false

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
