Workstation access

Start, stop, connect to, and diagnose a workstation: start/stop, shell, tmux, logs, and troubleshoot.

These commands manage a workstation’s lifecycle and connect to a running one. The access commands (shell, tmux, logs, troubleshoot) resolve the target’s address and login user from its status, and select a default workstation when you omit the name (the only, or alphabetically first, Running workstation).

rl workstation start / stop / restart

Power one or more workstations imperatively: the command equivalent of setting spec.stopped (and, for restart, spec.restartNonce) in a manifest. Target them by name, several names, or a label selector with -l. Alias: ws.

rl workstation start my-box
rl workstation stop my-box other-box
rl ws stop -l tier=dev            # every matching workstation
rl workstation restart my-box
rl ws restart -l tier=dev         # one logical restart across the whole set

A stopped workstation is halted but nothing is lost: its disk, installed tools, and state all persist; it rests in the Stopped phase until you start it again.

restart takes a workstation down and brings it back up — a real power cycle, not a reload of its configuration. It works on a stopped workstation too, which simply starts. When it targets several workstations they all share one restart, so re-running the same command is what triggers the next one.

FlagDescription
-l, --selector <k=v>Label selector (key=value[,key=value]) instead of name(s).
-n, --namespace <ns>Namespace.
-A, --all-namespacesOperate across all namespaces.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

rl workstation get-resolved-configuration <name>

Print the merged effective configuration a workstation resolves to: the answer to “what configuration will my workstation actually get?”.

rl workstation get-resolved-configuration my-box
rl ws get-resolved-configuration my-box -o json

The configuration is resolved on demand from the workstation, every WorkstationConfig layered onto it (explicit spec.configs[] references and selector matches), and any CloudIdentity governing it — by the same resolver the control plane uses to configure the workstation. It is not read from status.

FlagDescription
-o, --output <format>yaml (default) or json.
-n, --namespace <ns>Namespace.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

The document has four top-level keys:

KeyDescription
workstation<namespace>/<name>, so a pasted document says what it is about.
effectiveConfigHashThe configuration fingerprint the control plane wants, read from status.config.effectiveHash. Empty means the workstation has not been set up yet.
appliedConfigsEach config that shaped the workstation: its name, its source (explicit for a spec.configs[] reference, selector for a label match), and the config-layer priority it was applied at (lower applies first, so a higher priority wins).
effectiveThe whole merged spec — including everything status never carried: environment, files, scripts, sources, devtools, toolconfigs, and dotfiles.
appliedConfigs:
- name: ai-box
  priority: 200
  source: explicit
- name: base
  priority: 100
  source: selector
effective:
  devtools:
  - name: nodejs
  packages:
  - git
  shell: /bin/bash
  uid: 1000
  user: dev
effectiveConfigHash: 8f2c1a9e4d6b...
workstation: local/my-box

effective is the whole spec the workstation is set up to match, so a real document is longer than this: alongside what you declared, it carries the defaults Ringleader resolved for you (the login user and shell, the diagnostics settings, the node key authorized on the workstation, the agent version it should run).

Safe to paste into a ticket

This is the effective spec, not what is finally delivered to the workstation, so ${secret:NAME} references are printed verbatim. The command resolves no secret values and needs no access to any Secret.

A workstation homed at a control plane you are logged into is resolved by that control plane, so the answer is the one its control loop uses on the workstation — not a local approximation.

rl shell [workstation] [command...]

Open a shell on a workstation over SSH using the node key.

rl shell my-box                 # interactive shell
rl shell my-box -- uname -a     # run a remote command
rl shell                        # the default Running workstation
FlagDescription
-w, --workstation <name>Target workstation (alias --name).
-n, --namespace <ns>Namespace.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

Arguments after -- are run as the remote command verbatim; with none, you get an interactive shell.

Remote-command semantics

rl shell my-box -- <cmd> hands <cmd> to ssh, which behaves exactly as it does for ssh my-box <cmd>. Two consequences surprise people, and neither is specific to Ringleader:

  • Your local shell expands the arguments first. rl shell my-box -- ls ~ sends your machine’s home directory to the workstation. Quote it (rl shell my-box -- ls '~') to let the remote shell expand it, or use an absolute path.

  • The command runs in a non-login, non-interactive shell. /etc/profile, /etc/profile.d/* and ~/.profile are not sourced, so anything exported from a profile fragment is missing. That covers a PATH entry added by a devtool, the forwarded SSH agent’s SSH_AUTH_SOCK, and shell integrations such as fzf. Environment variables you declare under environment: in a WorkstationConfig are the exception: Ringleader also writes them to /etc/environment, which PAM reads for every SSH session, so those are set either way. Wrap the command in a login shell when you need the rest:

    rl shell my-box -- bash -lc 'node --version'

git over SSH in a remote command

Ringleader forwards your local SSH agent into the workstation and exports SSH_AUTH_SOCK for login shells. A non-interactive remote command therefore does not see the agent, and git clone git@github.com:… will fail. Until this is fixed, run it under a login shell as shown above: rl shell my-box -- bash -lc 'git -C /home/dev/repo pull'.

Using ssh directly

rl is a convenience wrapper, not a walled garden. While the daemon is running it maintains a real OpenSSH configuration for every workstation you can reach, and rewrites it in real time as workstations are created, started, stopped, and deleted. Point your own ~/.ssh/config at it, and every OpenSSH-speaking tool reaches a workstation with no rl in the loop.

Add this as the first line of ~/.ssh/config (create the file if it does not exist, with mode 600):

Include ~/.ringleader/ssh/config

That is all. With a running daemon and a Running workstation named my-box in namespace dev, all of these now work:

ssh my-box                                  # or my-box.dev, or my-box.dev.ringleader
ssh my-box uname -a
scp report.csv my-box:/home/dev/
rsync -av ./src/ my-box:/home/dev/src/
sftp my-box
git clone my-box:/home/dev/repo.git

So do the tools that read ~/.ssh/config for you: VS Code and Cursor Remote-SSH, JetBrains Gateway, and Ansible.

Each workstation gets three Host aliases: the bare name (my-box), the namespace-qualified name (my-box.dev), and a fully-qualified form (my-box.dev.ringleader). The .ringleader suffix is a deliberately non-resolvable pseudo-TLD, so the qualified alias can never shadow a real hostname.

Put the Include above everything else

OpenSSH uses the first value it obtains for each parameter, so an Include placed after your own Host * block is silently overridden by it. In particular, a Host * block that sets IdentityFile will make ssh offer the wrong key and fail to authenticate. Put the Include line above every Host and Match block in ~/.ssh/config.

For the same reason, note that the bare alias claims the workstation’s name in your SSH namespace: a workstation called prod would shadow a Host prod of your own. Use the <name>.<namespace>.ringleader spelling when in doubt.

What Ringleader manages for you

The Include pulls in ~/.ringleader/ssh/*.conf, one file per workstation. Every file is owned by the daemon and regenerated on change. Never edit them: your edits will be overwritten, and deleting a workstation prunes its file.

Each block carries:

  • the workstation’s current address, port, and login user, refreshed when they change;
  • Ringleader’s node key as the IdentityFile, with IdentitiesOnly yes so none of your own keys are offered;
  • a per-workstation known_hosts file with the host key pinned once the daemon has confirmed it, so your own ~/.ssh/known_hosts is never touched and recreating a workstation under the same name cannot produce a host-key-changed warning;
  • connection multiplexing (ControlMaster), so repeated commands reuse one connection instead of re-handshaking. (Not on Windows: Win32-OpenSSH does not support it.)

The configuration is only as fresh as the daemon: if rl daemon is not running, the files are frozen at their last state, and an address that changed since then will not connect. Check with rl daemon status.

rl code [workstation]

Open a workstation in a desktop editor over Remote-SSH: VS Code, Cursor, or VS Code Insiders. Also available as rl workstation code.

rl code my-box
rl code my-box --editor cursor
rl code my-box --path /home/dev/other-repo
rl code my-box --print            # show the command, launch nothing

The workstation is addressed by its collision-proof <name>.<namespace>.ringleader alias, and the folder opened is the first spec.sources[] path of the resolved configuration — override it with --path. With no sources, a window connects to the host with no folder open. The editor is autodetected in the order code, cursor, code-insiders; pin one with --editor.

Remote-SSH shells out to the system ssh and reads your own ~/.ssh/config, so this needs the Ringleader include wired in (rl ssh-config install — see Using ssh directly). A missing or misplaced include is warned about, not fatal.

The first connect downloads a server

On first connect VS Code downloads its own server (~100 MB) into the workstation from update.code.visualstudio.com. A workstation with restricted outbound access may sit at “Setting up SSH Host” until that fetch can complete.
FlagDescription
-w, --workstation <name>Workstation to open (defaults to the sole Ready one; required when several are).
--editor <name>code, cursor, or code-insiders. Default: autodetect in that order.
--path <dir>Absolute folder to open on the workstation, overriding the resolved source path.
--printPrint the command that would run, one argument per line, and launch nothing.
-n, --namespace <ns>Namespace.
-A, --all-namespacesResolve across all namespaces.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

rl tmux [workstation]

Attach to a persistent tmux session on the workstation (tmux new-session -A -s ringleader). On a transport drop it reconnects automatically after a backoff, ideal for long-running work over a flaky connection.

rl tmux my-box
FlagDescription
-w, --workstation <name>Target workstation (alias --name).
-n, --namespace <ns>Namespace.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

rl logs <workstation>

Stream the in-VM ringleader-agent logs (or a managed service’s logs), like kubectl logs. It automatically picks the systemd journal or the durable log file on the workstation.

rl logs my-box -f                 # follow
rl logs my-box --tail 200
rl logs my-box --since 30m
rl logs my-box --source service:code-server
FlagDescription
-f, --followStream new lines as they arrive.
--tail <N>Show only the last N lines (0 = all).
--since <duration>Window to show (e.g. 30m, 1h; journal only).
--source <source>agent (default) or service:<name>.
-n, --namespace <ns>Namespace.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

rl troubleshoot <workstation>

Gather a diagnostic bundle: the controller-side view (phase, conditions, last update), live system probes (OS, docker, disk, user, agent), and the in-VM agent’s provisioning timeline.

Run with no workstation to dump local status (daemon, origins/auth, version, host) instead. Either form takes --diagnostics to write a self-contained zip you can send for support, containing no tokens, secrets, or private keys.

For the whole diagnosis workflow — and how to capture and share a bundle from the desktop apps — see the Troubleshooting section and Generate a diagnostics bundle.

rl troubleshoot                          # local status to stdout
rl troubleshoot my-box                   # diagnose one workstation
rl troubleshoot my-box --failed          # only failed steps
rl troubleshoot my-box --kind devtool --since 1h
rl troubleshoot my-box --json            # machine-readable ledger
rl troubleshoot --diagnostics            # local-only zip
rl troubleshoot --all --diagnostics      # zip PLUS every workstation
rl troubleshoot my-box --diagnostics=out.zip
rl troubleshoot my-box --report-only     # only the in-VM diagnostic ledger
FlagDescription
--diagnostics[=PATH]Write a self-contained diagnostics zip (default ./ringleader-diagnostics-<timestamp>.zip).
--allWith --diagnostics: also include every workstation in the zip (an error without --diagnostics).
--failedShow only failed timeline steps.
--kind <kind>Filter the timeline by kind (user, package, devtool, tool-config, script, security-update, self-update).
--target <substring>Filter the timeline by target (substring match).
--since <duration>Steps started within this window (e.g. 30m, 1h).
--reconcile latestShow only the steps from the most recent configuration pass.
--limit <N>Show only the most recent N steps (0 = remote default).
--report-onlyPrint only the in-VM diagnostic ledger (no controller view or host probes).
--jsonEmit the in-VM diagnostic ledger report as JSON.
-n, --namespace <ns>Namespace.
--as <subject>Impersonate a subject.
--home <dir>Data directory.

Note

rl troubleshoot <workstation> --report-only pulls just the in-VM diagnostic ledger over the daemon’s SSH connection (no controller view or host probes) and renders it with the same formatter the in-VM agent uses.
