A bridge project between Apache SkyWalking and Kubernetes.

SWCK is a platform for the SkyWalking user that provisions, upgrades, maintains SkyWalking relevant components, and makes them work natively on Kubernetes.

• Java Agent Injector: Inject the java agent into the application pod natively.
  • Inject the java agent into the application pod.
  • Leverage a global configuration to simplify the agent and injector setup.
  • Use the annotation to customize specific workloads.
  • Synchronize injecting status to JavaAgent CR for monitoring purposes.
• Operator: Provision and maintain SkyWalking backend components.
• Custom Metrics Adapter: Provides custom metrics coming from SkyWalking OAP cluster for autoscaling by Kubernetes HPA

You can follow the Getting Started to deploy swck on a testing Kubernetes cluster quickly and try out the skywalking components end to end.

• Install the Operator
• Label the namespace with swck-injection=enabled

$ kubectl label namespace default(your namespace) swck-injection=enabled

• Add label swck-java-agent-injected: "true" to the workloads

For more details, please read Java agent injector

• To install the operator in an existing cluster, ensure you have cert-manager installed.
• Apply the manifests for the Controller and CRDs in release/config:

kubectl apply -f skywalking-swck-<SWCK_VERSION>-bin/config/operator-bundle.yaml

• Also, you could deploy the operator quickly based on Master Branch or Stable Release:

kubectl apply -k "github.com/apache/skywalking-swck/operator/config/default"

or

kubectl apply -k "github.com/apache/skywalking-swck/operator/config/default?ref=v0.8.0"

For more details, please refer to deploy operator

• Deploy the OAP server by referring to Operator Quick Start.
• Apply the manifests for an adapter in release/adapter/config:

kubectl apply -f skywalking-swck-<SWCK_VERSION>-bin/config/adapter-bundle.yaml

• Also, you could deploy the adapter quickly based on Master Branch or Stable Release:

kubectl apply -k "github.com/apache/skywalking-swck/adapter/config"

or

kubectl apply -k "github.com/apache/skywalking-swck/adapter/config?ref=v0.8.0"

For more details, please read Custom metrics adapter
