About argocd-advanced

argocd-advanced is a routing skill for advanced and automation-oriented ArgoCD tasks, directing users to focused reference material. Its coverage includes multi-cluster deployments, image updates, cluster bootstrapping, and application onboarding.

Key features

01Route tasks to relevant reference material
02Cover ApplicationSet multi-cluster propagation
03Guide image updates and Git write-back
04Provide cluster bootstrapping and app onboarding workflows
05Flag common configuration pitfalls and version requirements

Use cases

01Propagate applications across multiple clusters
02Automate image updates for ArgoCD-managed workloads
03Add a Kubernetes cluster to a GitOps environment
04Deploy a new workload from a template

ArgoCD Advanced

Routing entrypoint for advanced/automation-oriented ArgoCD operations. Each sub-area has its own deep reference, preserved verbatim from the pre-consolidation skills, under References/.

Scope routing

If you need to…	Read
Implement multi-cluster app propagation with ApplicationSet generators (list / cluster / git / matrix / merge / SCM / pull-request / plugin)	`References/applicationset.md` plus `References/applicationset/` for deep-dive reference docs
Automate container image updates for ArgoCD-managed workloads (update strategies, ImageUpdater CRD, git write-back)	`References/image-updater.md` + `References/image-updater/` + `References/ArgocdImageUpdater/` + `Samples/image-updater/`
Bootstrap a new Kubernetes cluster into the multi-repo GitOps environment	`References/cluster-bootstrapping.md` + `References/cluster-bootstrapping/` + `References/ArgocdClusterBootstrapping/`
Onboard a new workload via the standardized ApplicationSet template	`References/application-install.md` + `Workflows/application-install/` + `Tools/application-install/`

Decision tree

Need new cluster registered with ArgoCD?           -> cluster-bootstrapping
Need new service deployed to existing clusters?    -> application-install
Need to fan one app definition across N clusters?  -> applicationset
Need images to roll forward automatically?         -> image-updater

Gotchas

ApplicationSet generators are ordered. With matrix/merge generators, the parent generator's result is the input to the child — get the order wrong and you get an empty parameter set with no error.
Image Updater + git write-back requires a write credential. A read-only repo cred will silently leave images stuck on the original version. Check Image Updater pod logs for permission denied on push.
Bootstrap cluster secrets must carry the labels your ApplicationSet generators select on. A cluster registered without the expected label key/value is invisible to existing ApplicationSets — and there is no error, just zero apps.
application-install ships a your organization/ExampleApp-specific template. The Workflows assume the multi-repo layout. If you're not in that environment, treat it as a reference pattern, not a runnable recipe.
CRD versions matter. ApplicationSet ships with ArgoCD 2.3+; certain generators (SCM, pull request) need 2.5+. Read References/applicationset.md Version Compatibility before adopting.

Develop and host Miaoda (Spark/Miaoda) apps: app creation, local full-stack development, cloud generation and iteration, creative design (UI mockups / interactive prototypes / wireframes / landing pages / dashboards / slide decks / visual exploration), integration of AI-related capabilities, Feishu platform capabilities, or other external capabilities; log/Trace/monitoring metric/PV/UV queries; environment variable management; app collaborators and collaboration permissions; app roles and members; and automation triggers (scheduled / record changes / Webhook / Feishu approvals). Use when users want to develop or create a system, tool, platform, or app; develop locally or in the cloud, modify, deploy, publish, launch, or get a shareable link; create a page or website with HTML and deploy it to Miaoda; design, create a mockup, prototype, wireframe, PPT, deck, or visual exploration; or mention Miaoda/Spark/Miaoda apps (links like `/app/app_xxx` or `/page/<token>`, runtime domains like *.aiforce.cloud), app databases, app file storage, open API Keys, visibility, app collaborators/developer permissions, app roles/role members, production logs, API request volume, error volume, latency, traffic, environment variables, or setting up automation tasks, scheduled triggers, or approval-triggered automation for Miaoda apps. Not for regular cloud drive file uploads (lark-drive), Feishu document editing (lark-doc), or native slide creation (lark-slides).

azure-prepare

Prepare azd-based Azure projects for deployment: generates azure.yaml, infrastructure (Bicep/Terraform), and Dockerfiles for the Azure Developer CLI (azd) workflow. USE ONLY when the user explicitly wants to use azd as the deployment tool, or the project already has an azure.yaml file. DO NOT USE FOR: non-azd deployments, Python App Service code-only deploys (use python-appservice-deploy), or cross-cloud migration (use azure-cloud-migrate). WHEN: prepare app for azd, create azure.yaml, set up azd infrastructure, modernize app for Azure with azd, deploy with azd, function app, timer trigger, service bus trigger, event-driven function, managed identity, generate Bicep, generate Terraform, create and deploy to Azure.

Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.

azure-ai

Use for Azure AI: Search, Speech, OpenAI, Document Intelligence. Helps with search, vector/hybrid search, speech-to-text, text-to-speech, transcription, OCR.
