Installing protoc

Run brew install protobuf or make install-protobuf

Running the chaos dogfood server & client locally using Colima

Setup

(0) Ensure Colima is running

From the root directory, make sure you have already setup Colima: chaos-controller >> make colima-start

(1) Build the gRPC client and server images

Go into the dogfood directory to use its Makefile, and build the two images: chaos-controller >> cd dogfood chaos-controller/dogfood >> make colima-build-dogfood

They will be pushed your local docker repository as k8s.io/chaos-dogfood-client & k8s.io/chaos-dogfood-server.

(2) Deploy a gRPC client and server to Colima

Create the chaos-demo namespace (if necessary) and kubectl apply both Helm charts with this target: chaos-controller/dogfood >> make install

Development

(3) See your pods

Get pod name (such as chaos-dogfood-client-84596b6c5-8kdxl or chaos-dogfood-server-5fdcff889f-hblj2): chaos-controller/dogfood >> kubectl -n chaos-demo get pods -o wide

Sample kubectl output:

NAME                                    READY   STATUS        RESTARTS   AGE
chaos-dogfood-client-59bccfd49c-rn5wl   1/1     Running       0          41s
chaos-dogfood-server-854cc5f49d-gjbnc   1/1     Running       0          4s

chaos-controller/dogfood >> kubectl -n chaos-demo logs -l app=chaos-dogfood-client

Might output:

(4) Apply your disruptions

You can kubectl apply -f examples/<disruption.yaml> for any example/ disruption files. For gRPC disruption, you can follow these detailed steps.

Clean up

• Run make uninstall to kubectl delete both charts as well as remove the namespace.
