argo9s

A K9s-inspired terminal UI for monitoring Argo CD Applications in real time.

Screenshots

Offline demo (no cluster): argo9s --demo

Regenerate assets (needs VHS):

make build
PATH="$(go env GOPATH)/bin:$PATH" vhs docs/screenshots/demo.tape

Features

• Two backends: Kubernetes (kubeconfig / in-cluster) or Argo CD HTTP API (URL + token)
• Named connections in ~/.argo9s/config.yaml with startup picker (kubernetes, argocd-test, argocd-prod, …)
• Real-time watch of Applications (CRD watch or API stream/poll)
• Unified + type views: Applications, ApplicationSets, AppProjects
• K9s-style UX: j/k, / filter, : commands, ? help
• Project / name / sync filters
• Graph view (g): Argo UI–style tree (resource-tree API or live RS/Pods)
• Actions (when not read-only): sync, refresh, suspend/resume, delete
• Read-only by default
• --demo: offline sample apps for screenshots / VHS recordings
• --no-color: monochrome TUI (also NO_COLOR=1 or noColor: true in config)

Install

Homebrew

brew install vvrnv/tap/argo9s

Go

go install github.com/vvrnv/argo9s/cmd/argo9s@latest

Binary

Download from the releases page.

Build from source

git clone https://github.com/vvrnv/argo9s.git
cd argo9s
make build
./bin/argo9s

Releases are published automatically on v* tags via GoReleaser (GitHub Release + Homebrew formula in vvrnv/homebrew-tap).

Connections

1) CLI (one-shot Argo CD API)

argo9s --server https://argocd.example.com --auth-token "$TOKEN"
argo9s --server https://argocd.example.com --auth-token "$TOKEN" --insecure
# token also from ARGOCD_AUTH_TOKEN

2) Config profiles + picker

argo9s config init          # writes example ~/.argo9s/config.yaml
# edit connections, put tokens in env vars
export ARGOCD_TEST_TOKEN=...
export ARGOCD_PROD_TOKEN=...
argo9s                      # picker: kubernetes / argocd-test / argocd-prod
argo9s --connection argocd-prod
argo9s --pick               # force picker

Example ~/.argo9s/config.yaml:

defaultConnection: kubernetes
connections:
  - name: kubernetes
    type: kubernetes
  - name: argocd-test
    type: argocd
    server: https://argocd.test.example.com
    tokenEnv: ARGOCD_TEST_TOKEN
    readOnly: false
  - name: argocd-prod
    type: argocd
    server: https://argocd.prod.example.com
    tokenEnv: ARGOCD_PROD_TOKEN
    readOnly: true

readOnly on a connection overrides the global readOnly. CLI --readonly still wins when passed explicitly.

3) Kubernetes / in-cluster (original mode)

argo9s --connection kubernetes
argo9s --context my-cluster -n argocd

Navigation

CLI (autosync / sync)

# need writable connection (readOnly: false) or --readonly=false
argo9s --connection argocd-test --readonly=false app autosync on  guestbook
argo9s --connection argocd-test --readonly=false app autosync off guestbook
argo9s --connection argocd-test --readonly=false app resume  guestbook
argo9s --connection argocd-test --readonly=false app suspend guestbook
argo9s --connection argocd-test --readonly=false app sync    guestbook
argo9s --connection argocd-test --readonly=false app refresh guestbook --hard

| ctrl+d | Delete (confirm) | | ? | Help | | Q / :q | Quit |

Filters

:name guestbook       # filter by name substring
:n mpi                # short form
:name clear

:project default      # Applications in AppProject "default"
:p staging
:project clear

:sync outofsync       # only OutOfSync (yellow)
:sync synced
:outofsync
:sync clear

/text is a live substring filter across name/namespace/project/status.

Colors: Synced+Healthy = green · OutOfSync = yellow · Progressing = blue · Degraded = red · Unknown = gray
Disable: --no-color, NO_COLOR=1, or argo9s config set noColor true.

Graph view

1. Select an Application
2. Press g (or :graph)
3. Navigate nodes with j/k, esc to go back

Layout matches Argo CD UI (left → right):

app ── cm
    ├─ svc
    └─ deploy ── rs ── pod

Managed resources come from status.resources; ReplicaSets/Pods are loaded live from the cluster via ownerReferences.

Commands

Config

Stored at ~/.argo9s/config.yaml:

argo9s config view
argo9s config set readOnly false
argo9s config set noColor true
argo9s config set namespace argocd
argo9s config set allNamespaces true

How it works

Two backends, same TUI:

• Kubernetes — dynamic client watches Argo CD CRDs (applications / applicationsets / appprojects). Mutating actions patch the Application CR (refresh annotation, .operation.sync, syncPolicy).
• Argo CD HTTP API — list/watch via the server API (token auth); sync/refresh/suspend go through the same API. Preferred for full resource trees across destination clusters.
