Configure kubeconfig context

Verify cluster and namespace

Deploy sample function to test setup

Function YAML definition

Trigger YAML definition

Kubeless CLI configuration

Kubernetes manifests for controllers

Optional ConfigMaps and Secrets

kubeless function deploy <name> --runtime <runtime> --from-file <file> --handler <handler>

kubeless function ls

kubeless function call <name>

kubeless trigger create <type> <name> --function-name <function>

kubeless function logs <name>

No built-in i18n support

Message localization handled by function code

Event payloads may be language-agnostic

External services handle multi-language content

Focus on infrastructure, not content

Accessible via kubectl and CLI

HTTP triggers accessible over network

Functions can be invoked programmatically

Namespace isolation supports multi-tenant setups

Runs anywhere Kubernetes is supported

No UI provided - CLI and YAML based

Integrates with dashboards like Kubernetes Dashboard

Monitor functions via Prometheus/Grafana

Focus on API and event-based workflows

Web interfaces optional via HTTP triggers

Functions are stateless by design

Persistent state managed externally (DB, storage)

Secrets and ConfigMaps provide configuration

Scaling does not affect function state

Pods destroyed/recreated without losing data externally

Input and output via triggers

Supports JSON, HTTP, and message payloads

External databases for persistent storage

Environment variables and ConfigMaps for configuration

Logging and metrics stored in Kubernetes-compatible backends
