How ACK One Enables Multi‑Cluster GitOps and Unified Alert Management

ACK One Overview

ACK One is Alibaba Cloud’s distributed cloud container platform for hybrid‑cloud, multi‑cluster, and distributed‑computing scenarios. It provides a single control plane to manage Kubernetes clusters on Alibaba Cloud, edge locations, customer data centers, and other clouds.

Multi‑Cluster Capabilities

Unified control enables consistent application distribution, traffic routing, operations, and security across all managed clusters.

GitOps‑Based Application Distribution

GitOps treats a Git repository as the single source of truth for deployment manifests. The desired state in Git is continuously reconciled with the actual state in target clusters.

Low learning curve for developers familiar with Git.

Versioned manifests, fast rollback, auditability.

Security relies only on Git repository permissions.

Automatic synchronization between Git and clusters.

ArgoCD Integration

ArgoCD is an open‑source CNCF project that runs as a controller inside a Kubernetes cluster, watches the live state, and aligns it with the desired state stored in Git.

ACK One GitOps Implementation

ACK One embeds an ArgoCD instance and extends it with multi‑cluster support, including high‑availability deployments and cross‑cluster application distribution.

Native ArgoCD CLI and UI.

Automatic registration of managed clusters as ArgoCD target clusters.

Support for ArgoCD ApplicationSet for multi‑cluster distribution.

Out‑of‑the‑box, no‑ops required.

Example Workflow

Enable ArgoCD on the hub cluster:

aliyun adcp UpdateHubClusterFeature --ClusterId <your_clusterid> --EnableArgoCD true

Add a Git repository to ArgoCD:

argocd repo add https://code.aliyun.com/shuwei.hsw/echo-server.git --name echo-server
argocd repo list

Create a GitOps application:

argocd app create echo-server \
  --repo https://code.aliyun.com/shuwei.hsw/echo-server.git \
  --path helm/echo-server \
  --dest-namespace echo-server-cli \
  --dest-server https://47.97.xx.xx:6443

Deploy an ApplicationSet for multi‑cluster distribution:

cat <<EOF | kubectl apply -f -
apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: echo-server
spec:
  generators:
  - list:
      elements:
      - cluster: ack
        url: https://47.97.xx.xx:6443
      - cluster: idc
        url: https://47.97.xx.xx:6443
  template:
    metadata:
      name: '{{cluster}}-echo-server'
    spec:
      project: default
      source:
        repoURL: https://code.aliyun.com/shuwei.hsw/echo-server.git
        targetRevision: main
        path: manifests/directory/{{cluster}}
      destination:
        server: '{{url}}'
        namespace: multi-echo-server
EOF

View the applications in the native ArgoCD UI.

Unified Alert Management

ACK One extends the single‑cluster ACK alert system to a multi‑cluster context. The control instance defines alert rules, propagates them to child clusters, and continuously monitors consistency. It supports differentiated configurations such as GPU‑specific alerts, cluster‑specific thresholds, and custom contacts.

Summary

The release adds two major features: GitOps‑based multi‑cluster application distribution and unified alert management. ACK One can manage Kubernetes clusters in any region or infrastructure, providing consistent APIs for compute, networking, storage, security, monitoring, logging, jobs, applications, and traffic.
