The root directory of the cluster Docker. The default value is `/var/lib/docker`. If the actual directory is different from the default one, specify the root directory of Docker.
cluster_id
Cluster ID. If it is not specified, a default ID will be generated during installation (we recommend that you specify a cluster ID, as the generated default ID is less readable).
network
Private network or public network (default).
api_network
Private network or internet (default) for TencentCloud API.
./tencentcloud-cls-k8s-install.sh --secretid xxx --secretkey xx --region ap-guangzhou --network internet --api_region ap-guangzhou
5. Viewing

After the successful installation, view the tencent-cloud-cls-log Helm package.
helm list -n kube-system
5.2 View the components.
kubectl get pods -o wide -n kube-system |grep tke-log-agent
kubectl get pods -o wide -n kube-system |grep cls-provisioner
Run the above commands to check whether all components start properly. In normal cases, a tke-log-agent collection Pod and a cls-provisioner Pod will start on each host.
6. LogListener configuration

kubectl edit ds tke-log-agent -n kube-system
