# Octopus



**Octopus is no longer being actively maintained.**



[![Build Status](http://drone-pandaria.cnrancher.com/api/badges/cnrancher/octopus/status.svg)](http://drone-pandaria.cnrancher.com/cnrancher/octopus)

[![Go Report Card](https://goreportcard.com/badge/github.com/cnrancher/octopus)](https://goreportcard.com/report/github.com/cnrancher/octopus)



Octopus is a light-weight and cloud-native device management system for Kubernetes and k3s, it does not need to replace any basic components of the Kubernetes cluster. After Octopus deployed, the cluster can have the ability to manage edge devices as custom k8s resources.

## Idea



Like a real octopus, Octopus consists of the `brain` and `limbs`. The `brain` only needs to deploy one or automatically select a leader in HA mode. It only needs to process relatively concentrated information, such as verifying the existence of nodes and the existence of device models (types). Limbs need to be deployed on each edge node that can be connected to the device, and they communicate with the actual device through the device adaptor (Adaptors). Therefore, Octopus uses a DeviceLink YAML file (a custom-defined k8s object) to configure and manage its device connections.



For more details please refer to the [official documentation](https://cnrancher.github.io/docs-octopus/eng/).

## Quick-start



There are two ways to deploy the Octopus, for quick-start, you can use the manifest YAML file to bring up the Octopus. The installer YAML file is under the [deploy/e2e](./deploy/e2e) directory on Github.

```shell script

# install octopus

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus/master/deploy/e2e/all_in_one.yaml



# install ui

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus-api-server/master/deploy/e2e/all_in_one.yaml



# install adaptors

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus/master/adaptors/modbus/deploy/e2e/all_in_one.yaml

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus/master/adaptors/opcua/deploy/e2e/all_in_one.yaml

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus/master/adaptors/mqtt/deploy/e2e/all_in_one.yaml

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus/master/adaptors/ble/deploy/e2e/all_in_one.yaml

$ kubectl apply -f https://raw.githubusercontent.com/cnrancher/octopus/master/adaptors/dummy/deploy/e2e/all_in_one.yaml

```



Optionally, you can use this [repository](https://github.com/cnrancher/octopus-chart) hosts official Helm charts for Octopus. These charts are used to deploy Octopus to the Kubernetes/k3s Cluster.

```shell script

# add octopus helm repo

$ helm repo add octopus http://charts.cnrancher.com/octopus

$ helm repo update



# create octopus-system namespace

$ kubectl create ns octopus-system



# install octopus, ui and adaptors

$ helm install --namespace octopus-system octopus octopus/octopus

```
