About Multi-container Pod YAML Generator

A multi-container Pod runs a main application container together with one or more sidecars that share its network and storage. The Multi-container Pod YAML Generator writes that Pod from a form so you do not have to recall the core/v1 schema.

You set the Pod name and namespace, add a main container, and append sidecars - each with a name, image and optional ports. The resulting YAML is a valid core/v1 Pod.

Names are validated as RFC 1123 labels and container names must be unique. Problems are reported in a clear panel. Everything runs locally and nothing is uploaded.

Features

  • Main + sidecars - any number of containers.
  • Ports - optional container ports per container.
  • core/v1 - correct Pod schema.
  • Validation - RFC 1123 name and unique container names.
  • Copy / Download / Print - get pod.yaml wherever you need it.

How to Use

  1. Name the Pod. Type a valid RFC 1123 name.
  2. Add the main container (name + image).
  3. Add sidecars as needed.
  4. Watch the preview and export.

Examples

Example 1 - app + log sidecar. main web, sidecar fluentd.

Example 2 - app + proxy. main api, sidecar envoy.

Example 3 - ports. main nginx port 80.

Example 4 - three containers. app, sidecar sync, sidecar metrics.

Benefits

  • Correct schema - valid core/v1 Pod.
  • Sidecar pattern - main + helpers.
  • Validated - names and uniqueness checked.
  • Clean output - empty fields omitted.
  • Private - everything runs in the browser.
  • Copy, download or print - get the manifest where you need it.

Frequently Asked Questions

What is a multi-container Pod?
A Pod can run several containers that share storage and network. The sidecar pattern adds helper containers (logging, proxy, sync) alongside the main application container.
What container types are supported?
A main container (the application) and one or more sidecars. Functionally they are both plain containers in the Pod spec; the type only helps you group them in the form.
How are ports handled?
Each container can declare one or more container ports. Leave it blank if the container does not expose a port.
Is the name validated?
Yes. The Pod name must be a valid RFC 1123 label (lowercase letters, numbers and hyphens) and each container name must be unique.
Does this connect to a cluster?
No. Everything is assembled in your browser and nothing is uploaded.
Can I download it?
Yes. Copy the YAML, download pod.yaml, or print it.
