Extra configuration for fission-all

Parameter Description Default
createNamespace If true, create fission-function and fission-builder namespaces true
logger.influxdbAdmin Log database admin username admin
logger.fluentdImageRepository Logger fluentbit image repository index.docker.io
logger.fluentdImage Logger fluentbit image fluent/fluent-bit
logger.fluentdImageTag Logger fluentbit image tag 1.0.4
nats.enabled Nats streaming enabled true
nats.authToken Nats streaming auth token defaultFissionAuthToken
nats.clusterID Nats streaming clusterID fissionMQTrigger
natsStreamingPort Nats streaming service port 31316
azureStorageQueue.enabled Azure storage account name false
azureStorageQueue.key Azure storage account name ""
azureStorageQueue.accountName Azure storage access key ""
kafka.enabled Kafka trigger enabled false
kafka.brokers Kafka brokers uri broker.kafka:9092
kafka.version Kafka broker version nil
heapster Enable Heapster (only enable this in clusters where heapster does not exist already) false

Please note that deploying of Azure Storage Queue or Kafka is not done by Fission chart and you will have to explicitly deploy them.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release --set image=custom/fission-bundle,imageTag=v1 fission-all

If you're using minikube, set serviceType and routerServiceType to NodePort:

$ helm install --name my-release --set serviceType=NodePort,routerServiceType=NodePort fission-all

You can also set parameters with a yaml file (see values.yaml for what it should look like):

$ helm install --name my-release -f values.yaml fission-all
You can’t perform that action at this time.
