🐙 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

Install Script (Linux/macOS)

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

Homebrew (Linux/MacOS)

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

AUR (Arch User Repository)

yay -S argonaut-bin

Nix

With Nix and Flakes enabled, you can run or install Argonaut directly from the repository.

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";
  };
  # ...
}

Docker

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.

Download a binary

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")

Configuration Options

[appearance]

Option	Description	Default
theme	Color theme name (see available themes below)	tokyo-night

Available themes:

• Dark themes: catppuccin-mocha, dracula, gruvbox-dark, monokai, nord, one-dark, oxocarbon, solarized-dark, tokyo-night, tokyo-storm
• Light themes: catppuccin-latte, gruvbox-light, one-light, onehalf-light, solarized-light
• Accessibility: colorblind-safe, grayscale-lowchroma, high-contrast
• Special: inherit-terminal (uses your terminal's ANSI color palette)

You can also change the theme at runtime using the :theme <name> command.

[appearance.overrides]

Override individual theme colors with hex values. Available color keys:

• accent, warning, dim, success, danger, progress, unknown, info, text, gray
• selected_bg, cursor_selected_bg, cursor_bg, border, muted_bg, shade_bg, dark_bg

[sort]

Option	Description	Default
field	Sort field (name, sync, health)	name
direction	Sort direction (asc, desc)	asc

You can also change sorting at runtime using the :sort <field> <direction> command.

[k9s]

Integration settings for k9s, the Kubernetes TUI.

Option	Description	Default
command	Path to k9s executable	k9s
context	Override Kubernetes context when launching k9s	(none)

Press K on a resource in the tree view to open it in k9s.

[diff]

Settings for diff viewing and formatting.

Option	Description	Default
viewer	Interactive diff viewer command. Use {left} and {right} as placeholders for file paths.	(none)
formatter	Non-interactive diff formatter piped through before display	(none, falls back to delta if installed)

Examples:

[diff]
# Use VS Code as diff viewer
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.

[port_forward]

Settings for port-forward mode (when ArgoCD CLI is configured with server: port-forward).

Option	Description	Default
namespace	Kubernetes namespace where ArgoCD is installed	argocd
