## Deploy Sedna

Simply you can use the node which `cloudcore` of `kubeedge` is deployed at.

The shell commands below should to be executed in this node and **one terminal session** in case keeping the shell variables.

### Download source
```shell
git clone http://github.com/kubeedge/sedna.git
cd sedna
git checkout main
```

### Create CRDs

```shell
# create these crds including dataset, model, joint-inference etc.
kubectl create -f build/crds/
```

### Deploy GM

#### Prepare GM config
The content of `build/gm/gm-config.yaml`:
```yaml
kubeConfig: ""
master: ""
namespace: ""
localController:
server: http://localhost:9100
```
1. `kubeConfig`: config to connect k8s, default `""`
1. `master`: k8s master addr, default `""`
1. `namespace`: the namespace GM watches, `""` means that gm watches all namespaces, default `""`.
1. `localController`:
- `server`: to be injected into the worker to connect LC.

Edit the config file if you wish.

Note: if you just want to use the default values, don't need to run the below commands.
```shell
# edit build/gm/gm-config.yaml, here using sed command.
# alternative you can edit the config file manully.
GM_CONFIG_FILE=build/gm/gm-config.yaml
# here edit it with another LC bind ports if you wish or it's conflict with your node environment since LC is deployed in host namespace.
LC_BIND_PORT=9100
LC_SERVER="http://localhost:$LC_BIND_PORT"
# setting lc server
sed -i "s@http://localhost:9100@$LC_SERVER@" $GM_CONFIG_FILE
```

#### Run GM as a K8S Deployment:

We don't need to config the kubeconfig in this method said by [accessing the API from a Pod](https://kubernetes.io/docs/tasks/access-application-cluster/access-cluster/#accessing-the-api-from-a-pod).

1\. Create the cluster roles in order to GM can access/write the CRDs:
```shell
# create the cluster role
kubectl create -f build/gm/rbac/
```

2\. Deploy GM as deployment:
#### Deploy Sedna

Currently we need to deploy GM to a k8s node which edge node can access to.

In this example the node `sedna-control-plane` has a internal-ip 172.18.0.2, and `edge-node` can access it.

So we can set `GM_NODE_NAME=sedna-control-plane` in below instructions:

#### Debug
1\. Check the GM status:
```shell
kubectl get deploy -n sedna gm
```

### Deploy LC
Prerequisites:
1. Run GM successfully.
2\. Check the LC status:
```shell
kubectl get ds lc -n sedna
```

1\. Deploy LC as k8s daemonset:
3\. Check the pod status:
```shell
gm_node_port=$(kubectl -n sedna get svc gm -ojsonpath='{.spec.ports[0].nodePort}')
# fill the GM_NODE_NAME's ip which edge node can access to.
# such as gm_node_ip=192.168.0.9

# SEDNA_GM_NODE=sedna-control-plane
