Production Guide

This guide provides more in-depth details for running Teleport in Production.


Designing Your Cluster

Before installing anything there are a few things you should think about.

Firewall Configuration

Teleport services listen on several ports. This table shows the default port numbers.

Port Service Description Ingress Egress
3080 Proxy HTTPS port clients connect to. Used to authenticate tsh users and web users into the cluster. Allow inbound connections from HTTP and SSH clients. Allow outbound connections to HTTP and SSH clients.
3023 Proxy SSH port clients connect to after authentication. A proxy will forward this connection to port 3022 on the destination node. Allow inbound traffic from SSH clients. Allow outbound traffic to SSH clients.
3022 Node SSH port to the Node Service. This is Teleport's equivalent of port 22 for SSH. Allow inbound traffic from proxy host. Allow outbound traffic to the proxy host.
3025 Auth SSH port used by the Auth Service to serve its Auth API to other nodes in a cluster. Allow inbound connections from all cluster nodes. Allow outbound traffic to cluster nodes.
3024 Proxy SSH port used to create "reverse SSH tunnels" from behind-firewall environments into a trusted proxy server.


We have a detailed installation guide which shows how to install all available binaries or install from source. Reference that guide to learn the best way to install Teleport for your system and the come back here to finish your production install.

Filesystem Layout

By default a Teleport node has the following files present. The location of all of them is configurable.

Default path Purpose
/etc/teleport.yaml Teleport configuration file.
/usr/local/bin/teleport Teleport daemon binary.
/usr/local/bin/tctl Teleport admin tool. It is only needed for auth servers.
/usr/local/bin/tsh Teleport CLI client tool. It is needed on any node that needs to connect to the cluster.
/var/lib/teleport Teleport data directory. Nodes keep their keys and certificates there. Auth servers store the audit log and the cluster keys there, but the audit log storage can be further configured via auth_service section in the config file.

Running Teleport in Production

Systemd Unit File

In production, we recommend starting teleport daemon via an init system like systemd. If systemd and unit files are new to you, check out this helpful guide. Here's an example systemd unit file for the Teleport Proxy, Node and Auth Service.

There are a couple of important things to notice about this file:

  1. The start command in the unit file specifies --config as a file and there are very few flags passed to the teleport binary. Most of the configuration for Teleport should be done in the configuration file.

  2. The ExecReload command allows admins to run systemctl reload teleport. This will attempt to perform a graceful restart of Teleport but it only works if network-based backend storage like DynamoDB or etc 3.3 is configured. Graceful Restarts will fork a new process to handle new incoming requests and leave the old daemon process running until existing clients disconnect.

Start the Teleport Service

You can start Teleport via systemd unit by enabling the .service file with the systemctl tool.

# sudo cp teleport/examples/systemd/teleport.service /etc/systemd/system
$ cd /etc/systemd/system

# Use your text editor of choice to create the .service file
# Here we use vim
$ vi teleport.service

# use the file linked above as is, or customize as needed
# save the file
$ systemctl enable teleport
$ systemctl start teleport

# show the status of the unit
$ systemctl status teleport

# follow tail of service logs
$ journalctl -fu teleport

# If you modify teleport.service later you will need to
# reload the systemctl daemon and reload teleport
# to apply your changes
$ systemctl daemon-reload
$ systemctl reload teleport

You can also perform restarts or upgrades by sending kill signals to a Teleport daemon manually.

Signal Teleport Daemon Behavior
USR1 Dumps diagnostics/debugging information into syslog.
TERM, INT or KILL Immediate non-graceful shutdown. All existing connections will be dropped.
USR2 Forks a new Teleport daemon to serve new connections.
HUP Forks a new Teleport daemon to serve new connections and initiates the graceful shutdown of the existing process when there are no more clients connected to it. This is the signal sent to trigger a graceful restart.

Adding Nodes to the Cluster

We've written a dedicated guide on Adding Nodes to your Cluster which shows how to generate or set join tokens and use them to add nodes.

Security Considerations

SSL/TLS for Teleport Proxy

TLS stands for Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL). Teleport requires TLS authentication to ensure that communication between nodes, clients and web proxy remains secure and comes from a trusted source.

During our quickstart guide we skip over setting up TLS so that you can quickly try Teleport. Obtaining a TLS certificate is easy and is free with thanks to Let's Encrypt.

If you use certbot, you get this list of files provided:


The files that are needed for Teleport are these:

https_key_file: /path/to/certs/privkey.pem
https_cert_file: /path/to/certs/fullchain.pem

If you already have a certificate these should be uploaded to the Teleport Proxy and can be set via https_key_file and https_cert_file. Make sure any certificates files uploaded contain a full certificate chain, complete with any intermediate certificates required - this guide may help.

# This section configures the 'proxy service'
    # Turns 'proxy' role on. Default is 'yes'
    enabled: yes

    # The DNS name the proxy HTTPS endpoint as accessible by cluster users.
    # Defaults to the proxy's hostname if not specified. If running multiple
    # proxies behind a load balancer, this name must point to the load balancer
    # (see public_addr section below)

    # TLS certificate for the HTTPS connection. Configuring these properly is
    # critical for Teleport security.
    https_key_file: /var/lib/teleport/webproxy_key.pem
    https_cert_file: /var/lib/teleport/webproxy_cert.pem

When setting up on Teleport on AWS or GCP, we recommend leveraging their certificate managers.

When setting up Teleport with a Cloud Provider, it can be common to terminate TLS at the load balancer, then use an autoscaling group for the proxy nodes. When setting up the proxy nodes start Teleport with:

teleport start --insecure --roles=proxy --config=/etc/teleport.yaml

See Teleport Proxy HA for more info.

CA Pinning

Teleport nodes use the HTTPS protocol to offer the join tokens to the auth server. In a zero-trust environment, you must assume that an attacker can hijack the IP address of the auth server.

To prevent this from happening, you need to supply every new node with an additional bit of information about the auth server. This technique is called "CA pinning". It works by asking the auth server to produce a "CA pin", which is a hashed value of its private key, i.e. it cannot be forged by an attacker.

To get the current CA pin run this on the auth server:

$ tctl status
User CA  never updated
Host CA  never updated
CA pin   sha256:7e12c17c20d9cb504bbcb3f0236be3f446861f1396dcbb44425fe28ec1c108f1

The CA pin at the bottom needs to be passed to the new nodes when they're starting for the first time, i.e. when they join a cluster:

Via CLI:

$ teleport start \
   --roles=node \
   --token=1ac590d36493acdaa2387bc1c492db1a \
   --ca-pin=sha256:7e12c17c20d9cb504bbcb3f0236be3f446861f1396dcbb44425fe28ec1c108f1 \

or via /etc/teleport.yaml on a node:

  auth_token: "1ac590d36493acdaa2387bc1c492db1a"
  ca_pin: "sha256:7e12c17c20d9cb504bbcb3f0236be3f446861f1396dcbb44425fe28ec1c108f1"
    - ""


If a CA pin is not provided, Teleport node will join a cluster but it will print a WARN message (warning) into its standard error output.


The CA pin becomes invalid if a Teleport administrator performs the CA rotation by executing tctl auth rotate.

Secure Data Storage

By default the teleport daemon uses the local directory /var/lib/teleport to store its data. This applies to any role or service including Auth, Node, or Proxy. While an Auth node hosts the most sensitive data you will want to prevent unauthorized access to this directory. Make sure that regular/non-admin users do not have access to this folder, particularly on the Auth server. Change the ownership of the directory with chown

$ sudo teleport start

If you are logged in as root you may want to create a new OS-level user first. On Linux, create a new user called <username> with the following commands:

$ adduser <username>
$ su <username>
