monday

Monday is a CLI tool that unifies microservice development by running local applications and forwarding remote services from Kubernetes or SSH. It supports hot-reload, port-forwarding with auto-reconnect, and hostname-based traffic routing—reducing setup friction across developer teams.

What monday is

Written in Go, Monday manages local app execution (with environment variables and build steps) and establishes port-forwards to Kubernetes pods (via label selectors) or remote hosts over SSH/TCP. Configuration is YAML-based; the tool handles network interface manipulation and supports a terminal UI for monitoring.

Quickstart

Get the monday source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/eko/monday.gitcd monday# follow the project's README for install & configuration

Best use cases

Multi-service local development with hybrid Kubernetes dependencies

Run 2–3 services locally (Go, Node, Rust) while forwarding 5+ others from a staging Kubernetes cluster, all defined in one YAML config. Ideal for teams working on microservice architectures where full local replication is impractical.

Standardizing developer onboarding and environment setup

Replace ad-hoc bash scripts and README instructions with a single monday.yaml that all developers execute. Ensures consistent versions, environment variables, and port mappings across the team.

Hot-reload development workflows with automatic reconnection

Local services auto-restart on file changes; Kubernetes port-forwards auto-reconnect on network hiccups. Reduces manual intervention and context-switching during active development.

Implementation considerations

  • Requires sudo/root access to edit /etc/hosts and manage network interfaces; coordinate with security/infrastructure teams on developer machine policies.
  • Kubernetes credentials and context names must be pre-configured in kubectl; ensure kubeconfig is accessible and contexts are named consistently across the team.
  • YAML configuration can grow complex with many projects; plan directory structure (monday.localapps.yaml, monday.forwards.yaml) early to avoid maintenance burden.
  • Hot-reload watches file changes; use .env files or build artifacts to avoid rebuilding on every keystroke in large projects.
  • Port binding on localhost and hostname routing via /etc/hosts works on macOS/Linux; test thoroughly on non-standard setups (WSL, containers, VPNs).

When to avoid it — and what to weigh

  • Single monolithic application development — If your team builds and runs a single app, Monday's coordination overhead adds no value. A simple shell script or make target is more appropriate.
  • No Kubernetes or SSH infrastructure — Monday's core value is orchestrating local + remote services. Without a cluster or SSH-accessible services, it becomes a local app runner—use alternatives like nodemon, air, or entr instead.
  • Windows-primary development environment — Distribution and usage examples focus on macOS/Linux; network interface manipulation (hostname routing, IP binding) is Unix-centric. Windows support is unknown; may require heavy workarounds.
  • Strict security isolation requirements — Monday requires sudo/root access to manipulate host files and network interfaces. If your organization forbids developer sudo, deployment is blocked. Production use is unsupported by design.

Security considerations

Monday requires sudo/root to manipulate /etc/hosts and network interfaces; runs arbitrary commands from YAML (setup, build, run) with inherited user privileges. No built-in secrets management; relies on .env files or external tools. Kubernetes port-forwards inherit current user's kubeconfig credentials. SSH forwarding uses local SSH agent. Not designed for production; security posture for development-only use is Unknown. Audit YAML configs for command injection; validate SSH key access and kubeconfig permissions.

Alternatives to consider

Tilt

Cloud-native dev orchestration with built-in container/Kubernetes integration, richer UI, and more mature ecosystem. Better for teams already invested in containerization; steeper learning curve than Monday's YAML.

Skaffold + local services

Google-backed tool for Kubernetes workflows; handles build, push, deploy pipelines. Does not natively manage local app execution; requires separate tooling for mixed local/remote setups.

Make + shell scripts + kubefwd

Lightweight, no dependencies. Requires manual coordination; widely portable. Suitable for small teams with simpler microservice topologies; less convenient than Monday's unified config.

monday FAQ

Can I run Monday in a CI/CD pipeline or production?
No. Monday is designed for local development. It requires sudo, manipulates host files, and runs local binaries—unsuitable for automated or production environments. Use kubectl port-forward, Istio, or service mesh for prod scenarios.
What happens if a Kubernetes port-forward drops?
Monday auto-reconnects by re-establishing the kubectl port-forward. Connection interruption may occur briefly; no manual restart required. Auto-reconnect behavior is enabled by default.
Does Monday work on Windows?
Not clearly stated in documentation. Installation examples and network manipulation code are Unix-focused. Windows support via WSL or native binary is Unknown; requires testing or maintainer confirmation.
How do I handle secrets in Monday configuration?
Store secrets in .env files (referenced via env_file key) or use environment variable expansion. Monday does not manage secrets; integrate with external tools (HashiCorp Vault, AWS Secrets Manager, etc.) at the shell level.
