High Availability Deployment with K8S

agentUniverse provides standard working environment images specifically designed to support containerized deployments on Kubernetes (K8S) clusters. This guide will demonstrate how to utilize these images to deploy and set up a cluster within a K8S environment. You can get the full list of tags on this site. Official K8S Documentation: Kubernetes Setup Documentation

1. Resource Configuration

Firstly, you need to configure the necessary resource files. Below is an example YAML configuration file used to define the required Namespace, Deployment, and Service resources:

apiVersion: v1
kind: Namespace
metadata:
  name: agent-namespace
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: agentuniverse-deployment
  namespace: agent-namespace
  labels:
    app: agentuniverse
spec:
  replicas: 3
  selector:
    matchLabels:
      app: agentuniverse
  template:
    metadata:
      labels:
        app: agentuniverse
    spec:
      containers:
      - name: agentuniverse-container
        image: registry.cn-hangzhou.aliyuncs.com/agent_universe/agent_universe:0.0.9_centos8
        ports:
        - containerPort: 8888
        command: ["/bin/bash", "-c"]
        args: ["git clone [email protected]:antgroup/agentUniverse.git; mv agentUniverse/sample_standard_app /usr/local/etc/workspace/project; /bin/bash --login /usr/local/etc/workspace/shell/start.sh"]
        # Uncomment and replace "XXX" with your key to configure the agent
        # env:
        # - name: OPENAI_API_KEY
        #   value: "XXX"
---
apiVersion: v1
kind: Service
metadata:
  name: agentuniverse-service
  namespace: agent-namespace
spec:
  selector:
    app: agentuniverse
  ports:
  - protocol: TCP
    port: 9999
    targetPort: 8888

1.1 Setting Environment Variables for AgentUniverse Project

Method 1 (Recommended)

In the resource configuration file, uncomment the env section and replace value with your key. For additional security considerations, it's recommended to use officially recommended K8S methods, such as ConfigMap. Pliase refer to the ConfigMap Configuration Documentation for more details.

Method 2

Please refer to the description at the beginning of the configuration file: Quick Start Guide

2. Building Resources

Create and apply the aforementioned configuration file:

kubectl apply -f agentuniverse.yaml

3. Verifying Resources

Verify that all resources have been correctly deployed:

kubectl get all -n agent-namespace

Resource Deployment Status

4. Accessing AgentUniverse Services from Inside the Cluster

To access AgentUniverse services from within the cluster, use the following command line example:

kubectl exec -it [Pod Name] -n agent-namespace -- curl http://agentuniverse-service:9999

4.1 Examples

4.1.1 Connectivity Test

kubectl exec -it agentuniverse-deployment-55cfd778d-g7d9d -n agent-namespace -- curl http://agentuniverse-service:9999/echo

Connectivity Test

4.1.2 Q&A Test

kubectl exec -it agentuniverse-deployment-55cfd778d-g7d9d -n agent-namespace -- curl -X POST -H "Content-Type: application/json" -d '{"service_id":"demo_service","params":{"input":"(18+3-5)/2*4=?"}}' http://agentuniverse-service:9999/service_run
