### Running Tetragon in kind

The scripts in contrib/localdev will help you run Tetragon locally in a kind
cluster. First, ensure that docker, kind, kubectl, and helm are installed on
your system. Then, run the following commands:
This command will setup tetragon, kind cluster and install tetragon in it. Ensure docker, kind, kubectl, and helm are installed.

```shell
# Build Tetragon agent and operator images
make LOCAL_CLANG=0 image image-operator

contrib/localdev/bootstrap-kind-cluster.sh

# Install Tetragon
contrib/localdev/install-tetragon.sh --image cilium/tetragon:latest --operator cilium/tetragon-operator:latest

### Local Development in Minikube

You can also run the tetragon agent directly (instead of in a pod). Here we
describe how this can be done in minikube:

```shell
minikube start --driver=kvm2
minikube mount $HOME:$HOME # so that we can use .kube/config
./tetragon-operator --kube-config ~/.kube/config
make STATIC=1 tetragon
minikube ssh -- 'sudo mkdir -p /var/run/cilium/tetragon'
minikube ssh sudo "sh -c 'NODE_NAME=minikube /home/kkourt/src/tetragon/tetragon --bpf-lib /home/kkourt/src/tetragon/bpf/objs --server-address unix:///var/run/cilium/tetragon/tetragon.sock --enable-k8s-api --k8s-kubeconfig-path /home/kkourt/.kube/config'"
```
