Installation Guide

Cyclone has been tested with Kubernetes 1.12, 1.13 and 1.14.

Install With Helm


Cyclone can be easily installed with Helm with a version higher than 2.10, refer to helm install guide for Helm installation.

You can use helm template to generate Kubernetes manifests for Cyclone and then install it using kubectl apply, or you can use helm install to manage Cyclone installation by Tiller. You can install Tiller after Helm is ready with command:

$ helm init --history-max 200

Customizable Installation

The simplest way to install Cyclone is using Helm chart. By default, images are pulled from DockerHub, so make sure DockerHub is accessible from your cluster.

$ helm install --name cyclone --namespace cyclone-system ./helm/cyclone

If you want to use your own private registry, you can configure it as:

$ helm install --name cyclone --namespace cyclone-system --set,imageRegistry.project=release ./helm/cyclone

For more detailed configuration, please use values file, default values file is a good reference on how to write it.

$ helm install --name cyclone --namespace cyclone-system -f <path-to-your-values-file> ./helm/cyclone

If you want to release after change charts, you can upgrade with command:

$ helm upgrade cyclone ./helm/cyclone

If you want to uninstall Cyclone, you can clean up it with command:

$ helm delete --purge cyclone


Common Configurations

Parameter Description Default
imageRegistry.registry Image registry where to pull images
imageRegistry.project Project in the registry where to pull Cyclone component images caicloud
imageRegistry.libraryProject Project in the registry where to pull common images, like busybox library
serverAddress Address of the Cyclone Server (provides Restful APIs) cyclone-server.default.svc.cluster.local::7099
systemNamespace Namespace where Cyclone will be installed default

Workflow Engine Configurations

Parameter Description Default
engine.images Images used in workflow engine, for example, engine.images.gc (default alpine:3.8) defines image used for garbage collection. alpine:3.8 for engine.images.gc, docker:18.03-dind for dind
engine.gc.enabled Whether enable garbage collection true
engine.gc.delaySeconds Time to wait before cleaning up execution of a workflow. It gives users chance to check the execution details (for example, pods, data on PVC) when execution finished 300
engine.gc.retry How many times to retry (include the initial one, so 1 means no retry) when performing GC 1
engine.limits.maxWorkflowRuns Maximum number of execution records to keep for each workflow 50
engine.resourceRequirement Default resource requirements that would be applied to each stage, if non specified when execute a workflow CPU: 50m/100m, Memory: 128Mi/256Mi
engine.notification.url URL where to notify workflow execution result, it's Cyclone server by default http://cyclone-server.default.svc.cluster.local::7099/apis/v1alpha1/notifications
engine.developMode Whether it's in develop mode, in develop mode, ImagePullPolicy would be Always in the engine true
engine.executionContext.namespace If no execution context(cluster, namespace, PVC) specified when run workflow, use this namespace in control cluster cyclone-system
engine.executionContext.pvc If no execution context specified when run workflow, use this PVC cyclone-pvc-system

Cyclone Server Configurations

Parameter Description Default
server.listenAddress Address where Cyclone server will serve
server.listenPort Port that Cyclone server will serve on 7099
server.nodePort Node port that Cyclone server will expose its service from the cluster 30011
server.init.defaultTenant Whether init default tenant system in the installation true
server.init.templates Whether init stage templates true
server.openControlCluster When a tenant created, whether to open control cluster for the tenant to run workflow, to open control cluster, PVC would be created true
server.pvc.storageClass Default StorageClass used to create PVC Empty string
server.pvc.size Default PVC size if not specified 10Gi
server.resourceRequirement Resource quota applied to namespace create for tenant to run workflow CPU: 1/2, Memory: 2Gi/4Gi
server.storageWatcher.reportUrl URL to report PVC usage, it's Cyclone server by default http://cyclone-server.default.svc.cluster.local::7099/apis/v1alpha1/storage/usages
server.storageWatcher.intervalSeconds Time interval to report PVC usage 30
server.storageWatcher.resourceRequirements Resource requirements applied to the storage watcher pod CPU: 50m/100m, Memory: 32Mi/64Mi

Cyclone Web Configurations

Parameter Description Default
web.replicas Replicas of cyclone web 1
web.listenPort Port Cyclone web will listen on 80
web.nodePort Node port that Cyclone web will expose its service 30022

Build Images

If you'd like to build images from the source code, please do it as:

$ docker login <registry> -u <user> -p <pwd>
$ make push REGISTRIES=<registry>/<project>

Here / specifies the registry and project where to push your images, for example,

Then install Cyclone with Helm.

$ helm install --name cyclone --namespace cyclone-system --set imageRegistry.registry=<registry>,imageRegistry.project=<project> ./helm/cyclone
