## Overview

- [Containers](https://developers.cloudflare.com/containers/index.md): Run serverless containers alongside Workers to handle resource-intensive workloads, custom runtimes, and existing container images on Cloudflare.

## Get started

- [Get started](https://developers.cloudflare.com/containers/get-started/index.md): Deploy your first Container on Cloudflare by building an image, configuring a Worker, and routing requests to container instances.

## Concepts

- [Concepts](https://developers.cloudflare.com/containers/concepts/index.md): Understand the key ideas behind Containers, including their lifecycle and placement.
- [Lifecycle of a Container](https://developers.cloudflare.com/containers/concepts/architecture/index.md): Understand how a Container is deployed, started, routed, and shut down across Cloudflare's network.
- [Placement](https://developers.cloudflare.com/containers/concepts/placement/index.md): Control where your containers run with regional and jurisdictional constraints.

## Guides

- [Guides](https://developers.cloudflare.com/containers/guides/index.md): Task-focused guides for deploying containers, developing locally, managing images, executing commands, and connecting over SSH.
- [Deploy Containers](https://developers.cloudflare.com/containers/guides/deploy/index.md): Deploy from your machine or Workers Builds, including how images and container instances update.
- [Execute commands](https://developers.cloudflare.com/containers/guides/execute-commands/index.md): Run additional processes inside an active Container.

- [Local Development](https://developers.cloudflare.com/containers/guides/local-dev/index.md): Learn how to run Container-enabled Workers locally with `wrangler dev` and `vite dev`.
- [SSH](https://developers.cloudflare.com/containers/guides/ssh/index.md): Connect to running container instances with SSH.

## Configuration

- [Configuration](https://developers.cloudflare.com/containers/configuration/index.md): Configure Containers in Wrangler, connect them to Workers and bindings, set environment variables, tune scaling and routing, and manage rollouts.
- [Environment Variables](https://developers.cloudflare.com/containers/configuration/environment-variables/index.md): Runtime and user-defined environment variables available inside Container instances.
- [Handle outbound traffic](https://developers.cloudflare.com/containers/configuration/outbound-traffic/index.md): Intercept and handle outbound HTTP from containers using Workers.
- [Rollouts](https://developers.cloudflare.com/containers/configuration/rollouts/index.md): How container instances update after a deploy, including step percentages, grace periods, and rollout modes.
- [Scaling and Routing](https://developers.cloudflare.com/containers/configuration/scaling-and-routing/index.md): Scale Container instances using explicit IDs or the getRandom helper for stateless load balancing.
- [Connect to Workers and Bindings](https://developers.cloudflare.com/containers/configuration/workers-connections/index.md): Access KV, R2, Durable Objects, and other bindings from a container.
- [Wrangler configuration](https://developers.cloudflare.com/containers/configuration/wrangler/index.md): Configure a Container, its Durable Object binding, and its migration in Wrangler.

## API
