🐙 Argonaut — Argo CD TUI

Argonaut is a keyboard-first terminal UI for Argo CD, built with Bubbletea. Browse apps, scope by clusters/namespaces/projects, stream live resource status, trigger syncs, inspect diffs in your favorite pager, and roll back safely — all without leaving your terminal.

❤️ 🐶 Inspired by the great UX of k9s — but for Argo CD.

📦 Prerequisites

Argo CD CLI installed
Delta installed for enhanced diffs (optional, falls back to git)

🚀 Installation methods

<details> <summary>Install Script (Linux/macOS)</summary>

curl -sSL https://raw.githubusercontent.com/darksworm/argonaut/main/install.sh | sh

The install script automatically detects your system (including musl vs glibc on Linux) and downloads the appropriate binary from the latest release.

You can also install a specific version:

curl -sSL https://raw.githubusercontent.com/darksworm/argonaut/main/install.sh | sh -s -- v1.13.0

</details> <details> <summary>Homebrew (Linux/MacOS)</summary>

brew tap darksworm/homebrew-tap
brew install darksworm/tap/argonaut

</details> <details> <summary>AUR (Arch User Repository)</summary>

yay -S argonaut-bin

</details> <details> <summary>Nix</summary> With Nix and Flakes enabled, you can run or install Argonaut from nixpkgs or directly from the repository.

nixpkgs

Argonaut is currently available on the unstable channel of nixpkgs. So you can install it using

nix-env -iA nixos.argonaut

On other systems (macOS, non-NixOS Linux):

nix-env -iA nixpkgs.argonaut

or by adding it to your systemPackages.

environment.systemPackages = with pkgs; [ argonaut ];

Run Directly

To run Argonaut without permanently installing it, use the nix run command:

nix run github:darksworm/argonaut

Development Shell

To enter a development shell with Argonaut and its dependencies (like Go, Delta, and Argocd) available for development, use the nix develop command:

nix develop github:darksworm/argonaut

Flakes

If you are using Flakes to manage your systems add this to your Flake:

inputs = {
  argonaut = {
    url = "github:darksworm/argonaut";
    inputs.nixpkgs.follows = "nixpkgs";
  };
  # ...
}

</details> <details> <summary>Docker</summary>

Pull the image:

docker pull ghcr.io/darksworm/argonaut:latest

Run with mounted Argo CD config (as your host user to preserve permissions):

docker run -it --rm \
  -u $(id -u):$(id -g) \
  -v ~/.config/argocd:/home/appuser/.config/argocd:ro \
  ghcr.io/darksworm/argonaut:latest

The container needs access to your Argo CD configuration for authentication. The :ro flag mounts it as read-only for security.

</details> <details> <summary>Download a binary</summary>

You can download binaries and packages in from the latest release.

⚡ Quickstart

# Log in to your Argo CD server
argocd login

# Start Argonaut
argonaut

✨ Highlights

Instant app browsing with live updates (NDJSON streams)
Scoped navigation: clusters → namespaces → projects → apps
Command palette (:) for actions: sync, diff, rollback, resources, etc.
Live resources view per app with health & sync status
External diff integration: prefers delta, falls back to git --no-index diff | less
Guided rollback with revision metadata and progress streaming
Keyboard-only workflow with Vim-like navigation

Advanced Features

Client certificate authentication

Argonaut supports client certificate authentication. You just need to pass a couple arguments to the argonaut command:

argonaut --client-cert=/path/to/cert --client-cert-key=/path/to/key

Self-signed certificates

If your Argo CD server uses a self-signed certificate, you can provide a custom CA certificate to trust:

argonaut --ca-cert=/path/to/ca.crt

Port-forward mode

If your Argo CD server isn't directly accessible (e.g., running in a private cluster), Argonaut can connect via kubectl port-forward:

# Configure ArgoCD CLI for port-forward mode
argocd login --port-forward --port-forward-namespace argocd

# Start Argonaut (automatically detects port-forward mode)
argonaut

Requirements:

kubectl configured with access to the cluster
ArgoCD server pod running in the target namespace

Custom namespace: If ArgoCD is installed in a different namespace, add to your config:

# ~/.config/argonaut/config.toml
[port_forward]
namespace = "my-argocd-namespace"

⚙️ Configuration

Argonaut stores its configuration in a TOML file at ~/.config/argonaut/config.toml (or $XDG_CONFIG_HOME/argonaut/config.toml).

You can override the config path with the ARGONAUT_CONFIG environment variable.

Example Configuration

[appearance]
theme = "tokyo-night"

[appearance.overrides]
# Override individual theme colors (hex format)
# accent = "#ff79c6"
# success = "#50fa7b"

[sort]
field = "name"      # name, sync, health
direction = "asc"   # asc, desc

[k9s]
command = "k9s"           # Path to k9s executable
context = ""              # Override Kubernetes context for k9s

[diff]
viewer = ""               # Interactive diff viewer (e.g., "code --diff {left} {right}", "meld {left} {right}")
formatter = ""            # Diff formatter command (e.g., "delta --side-by-side")

[http_timeouts]
request_timeout = "10s"   # Timeout for HTTP requests (increase for large deployments)

# Start in apps view instead of clusters (supports :command syntax)
default_view = "apps"

viewer = "code --diff {left} {right} --wait"

# Use meld as diff viewer
viewer = "meld {left} {right}"

# Use delta with custom options
formatter = "delta --side-by-side --line-numbers"

If no viewer is set, diffs are shown in an internal pager. If no formatter is set but delta is installed, it will be used automatically.
