mirrord uses your machine's default kubeconfig for access to the Kubernetes API.

VS Code Extension

Installation

Get the extension here.

How To Use

• Click "Enable mirrord" on the status bar
• Start debugging your project
• Choose pod to impersonate
• The debugged process will be plugged into the selected pod by mirrord

IntelliJ Plugin

Installation

Get the plugin here.

How To Use

• Click the mirrord icon in the Navigation Toolbar
• Start debugging your project
• Choose a namespace and pod to impersonate
• The debugged process will be plugged into the selected pod by mirrord

CLI Tool

Installation

You can use either

brew install metalbear-co/mirrord/mirrord

or

curl -fsSL https://raw.githubusercontent.com/metalbear-co/mirrord/main/scripts/install.sh | bash

or using Nix (not official, community maintained):

# Using nix-env (legacy)
nix-env -iA nixpkgs.mirrord

# Using nix profile (recommended)
nix profile install nixpkgs#mirrord

or on Windows using Chocolatey:

choco install --pre mirrord

How To Use

mirrord exec <process command> --target <target-path>

e.g.

mirrord exec node app.js --target pod/my-pod

How It Works

When you select a pod to impersonate, mirrord launches a pod on the same node as the pod you selected. The new pod is then used to connect your local process and the impersonated pod: it mirrors incoming traffic from the pod to your process, routes outgoing traffic from your process through the pod, and does the same for file reads, file writes, and environment variables. You can read more about it here.

Additional capabilities

Container run inside the pod launched by mirrord requires additional Linux capabilities:

• CAP_NET_ADMIN and CAP_NET_RAW - for modifying routing tables
• CAP_SYS_PTRACE - for reading target pod environment
• CAP_SYS_ADMIN - for joining target pod network namespace

However, you can disable any subset of those in the configuration. This will possibly limit mirrord functionalities or even make it unusable in some setups.

MIRRORD_AGENT_DISABLED_CAPABILITIES=CAP_NET_RAW,CAP_SYS_PTRACE mirrord exec node app.js --target pod/my-pod

Using mirrord with AI coding agents

mirrord works first-class with Claude Code, Cursor, Codex CLI, Gemini CLI, and other AI coding agents, letting them run and verify generated code against real cluster services without deploying.
