ebman

A k9s-style TUI for AWS Elastic Beanstalk. Triage red envs, stream logs, edit option settings, deploy new versions — all from the keyboard. If you've used k9s with Kubernetes, the muscle memory carries: : for commands, / to filter, Enter to drill in, ? for context-aware help.

Captured from ebman --demo, the synthetic-fleet mode that ships with the binary. Regenerate the gif with vhs demo.tape after a code change.

Install

Homebrew (macOS / Linux):

brew install tombaldwin/tap/ebman

Cargo:

cargo install ebman

Pre-built binary: download the tarball for your platform from the GitHub Releases page, verify the *.sha256 next to it, extract, and put ebman on your PATH.

Tested on Rust 1.94.1+ (the AWS SDK sets the floor). macOS (Apple Silicon + Intel) and Linux x86_64. AWS SDK uses the standard credentials chain (AWS_PROFILE / AWS_REGION env, ~/.aws/credentials, instance role, etc.).

For the prettier glyph set (Powerline pill chain, Nerd Font tab icons), see docs/fonts.md. The default icons = "unicode" works fine in any terminal.

Quickstart

ebman                                  # launch the TUI
ebman --read-only                      # disable all write surfaces (audit-friendly)
ebman --demo                           # synthetic fleet (no AWS calls) — for screenshots / VHS
ebman --version
ebman --help

Once running, press ? for a per-context keymap (Detail, DLQ, Action menu, Saved-configs overlay all have scoped help).

Triage workflow

Production env goes red at 3am. From your terminal:

1. ebman — launch; prod-api shows up tinted red in the table
2. /prod-api ↵ — jump to it
3. ! — open :why: recent events / alarms / instance health / last deploys, all in one overlay
4. :diff prod-api staging-api — confirm staging is still on the previous version
5. :rollback — redeploy the last-known-good version label, with a 5-second undo window
6. Action + outcome land in ~/.cache/ebman/audit.log

Five keystrokes to triage, one command to fix. The AWS-console alternative is a minimum of five page-loads, two tabs, and zero audit trail.

Built for operators who triage EB envs daily and don't want the AWS console round-trip — or the eb deploy ; aws elasticbeanstalk describe-events --max-items 50 | jq ... shell-pipeline every time something goes red.

Highlights

• Live env table with sort / filter / group-by-app / health sparkline / severity tints / mouse support.
• Per-env drill-down — tabs for Health / Events / Instances / Metrics / Queue / Logs / Config.
• Red-env triage — :why opens a one-screen diagnostic: recent events + alarms + instance health + last deploys, with a DLQ peek for Worker envs.
• Incident mode — :incident START "headline" freezes deploys fleet-wide, pins a header banner with a running clock, and audit-logs the window; :event-tail streams EB events across every env in one overlay; ebman audit replay <line-id> re-runs an audited action for post-incident review.
• Honest health — envs with alarms in ALARM, DLQs with messages, or stale platforms surface on the row itself, not behind a tab.
• Forensics — :diff env-A env-B for option-setting deltas, :lineage for the deploy timeline, :alarm-history NAME for CW state transitions, :config-diff-local against a local EB CLI saved config.
• Daily-driver writes — env vars, tags, deploys (label / local zip / S3, with --preview), saved configs, CW alarms CRUD, ALB scheme, instance type, capacity, deployment policy, plus a generic :set-option escape hatch.
• Worker / SQS — DLQ viewer with resend, typed-name purge, bulk delete, peek-and-tail.
• SSM — :ssh i-abc opens an embedded session; :ssm-run "<cmd>" fans a shell command across the env's instances.
• Multi-account / multi-region — :region all parallel queries, :account NAME via sts:AssumeRole, :find-env / :org-health walk every ~/.aws profile + configured account.
• Bulk ops — space multi-selects, then :batch-* fans out in parallel with audit + pending-pill rows.
• Safety + audit — --read-only flag, typed-name confirms, per-env / per-account read-only pins, full audit log at ~/.cache/ebman/audit.log.
• Headless / scriptable — --control-socket PATH, ebman envs --json, ebman action rebuild --env NAME, ebman ctl screen / state / cmd <:cmd>.
• Agent-native (MCP) — ebman mcp serve exposes the read surface (envs, lint, drift, option settings, events, versions, cost) as MCP tools, so Claude Code or any MCP client can query your fleet first-class instead of shelling out and re-parsing. --allow-writes adds opt-in, two-phase deploy / restart / rebuild / terminate / set_option (the tool returns a plan, then confirm_action dispatches) — honouring the same safety pins, read-only, and a cross-process incident freeze the TUI uses, and auditing every dispatch.

Why ebman?

You probably already have one of these:

ebman is k9s-for-EB: keyboard-driven, drill-down-first, focused on operators who triage red envs daily and want one screen for "what's wrong" and "what changed". The nearest peer in the broader Rust-TUI / k9s-style space is e1s (k9s-for-ECS); ebman is broader on the write surface and adds multi-account fan-out, an audit log, per-env safety pins, and an embedded SSM-session pane.

Documentation

• Keys — normal mode, detail view tabs, DLQ viewer.
• Command reference — every :command grouped by job (navigation, per-env, write, multi-account, bulk).
• Configuration — ~/.config/ebman/config.toml, plugin commands, project-local pinning.
• Fonts — installing a Nerd Font for the Powerline glyph set.
• Headless interface — --control-socket + ebman ctl for scripts / CI; the CLI subcommands; shell completion (ebman completions); and the ebman mcp serve MCP server (read tools + opt-in two-phase writes) for Claude Code and other agents — run ebman mcp setup for the exact registration commands.
• Safety, privacy, what's stored locally — read-only mode, audit log, bug-report scrubbing.
• Architecture — module map, how a keystroke becomes an AWS call, and the invariants the compiler doesn't enforce.
• Development — build / test / clippy + distribution notes.
• Contributing — setup, the pre-PR checklist, and what makes a change easy to accept.
