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>

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
