EventMesh Operator Quick Start

Preparing:

• docker
• golang (version 1.19)
• kubernetes(kubectl)
  Note: There is some compatibility between kubernetes an docker, please check the version compatibility between them and download the corresponding version to ensure that they work properly together.

Quick Start

Deployment

1. Go to the eventmesh-operator directory.

cd eventmesh-operator

1. Install CRD into the specified k8s cluster.

make install

# Uninstall CRDs from the K8s cluster
make uninstall

If you get error eventmesh-operator/bin/controller-gen: No such file or directory
Run the following command:

# download controller-gen locally if necessary.
make controller-gen
# download kustomize locally if necessary.
make kustomize

Success

# run the following command to view crds information:
kubectl get crds

NAME                                      CREATED AT
connectors.eventmesh-operator.eventmesh   2023-11-28T01:35:21Z
runtimes.eventmesh-operator.eventmesh     2023-11-28T01:35:21Z

1. Create and delete CRs:
   Custom resource objects are located at: /config/samples
   When deleting CR, simply replace create with delete.

# Create CR for eventmesh-runtime、eventmesh-connector-rocketmq,Creating a clusterIP lets eventmesh-runtime communicate with other components.
make create

#success:
configmap/runtime-config created
runtime.eventmesh-operator.eventmesh/eventmesh-runtime created
service/runtime-cluster-service created
configmap/connector-rocketmq-config created
connectors.eventmesh-operator.eventmesh/connector-rocketmq created

# View the created Service.
kubectl get service
NAME                      TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)     AGE
runtime-cluster-service   ClusterIP   10.109.209.72   <none>        10000/TCP   17s

# Delete CR
make delete

1. Run eventmesh-operator create pods

make run
# success run log
go fmt ./...
go vet ./...
go run ./main.go

kubectl get pods
