Introduction

Teleport is the easiest, most secure way to access all your infrastructure. Teleport is an identity-aware, multi-protocol access proxy which understands SSH, HTTPS, RDP, Kubernetes API, MySQL, MongoDB and PostgreSQL wire protocols.

On the server-side, Teleport is a single binary which enables convenient secure access to behind-NAT resources such as:

• SSH nodes - SSH works in browsers too!
• Kubernetes clusters
• PostgreSQL, MongoDB, CockroachDB and MySQL databases
• Internal Web apps
• Windows Hosts
• Networked servers

Teleport is trivial to set up as a Linux daemon or in a Kubernetes pod. It's rapidly replacing legacy sshd-based setups at organizations who need:

• Developer convenience of having instant secure access to everything they need across many environments and cloud providers.
• Audit log with session recording/replay for multiple protocols
• Easily manage trust between teams, organizations and data centers.
• Role-based access control (RBAC) and flexible access workflows (one-time access requests)

In addition to its hallmark features, Teleport is interesting for smaller teams because it facilitates easy adoption of the best infrastructure security practices like:

• No need to manage shared secrets such as SSH keys: Teleport uses certificate-based access with automatic certificate expiration time for all protocols.
• Two-factor authentication (2FA) for everything.
• Collaboratively troubleshoot issues through session sharing.
• Single sign-on (SSO) for everything via Github Auth, OpenID Connect, or SAML with endpoints like Okta or Active Directory.
• Infrastructure introspection: Use Teleport via the CLI or Web UI to view the status of every SSH node, database instance, Kubernetes cluster, or internal web app.

Teleport is built upon the high-quality Golang SSH implementation. It is fully compatible with OpenSSH, sshd servers, and ssh clients.

Installing and Running

| Follow the Installation Guide

Download the latest binary release, unpack the .tar.gz and run sudo ./install. This will copy Teleport binaries into /usr/local/bin.

Then you can run Teleport as a single-node cluster:

sudo teleport start

In a production environment, Teleport must run as root. For testing or non-production environments, run it as the $USER:

chown $USER /var/lib/teleport

• In this case, you will not be able to log in as another user.

Docker

| Follow the Docker-Compose Getting Started Guide

Deploy Teleport

If you wish to deploy Teleport inside a Docker container:

# This command will pull the Teleport container image for version 8
docker pull public.ecr.aws/gravitational/teleport:8

View latest tags on Amazon ECR Public | gravitational/teleport

For Local Testing and Development

Follow the instructions in the [docker/README](docker/README.md) file.

To run a full test suite locally, see [the test dependencies list](BUILD_macos.md#local-tests-dependencies)

Building Teleport

The teleport repository contains the Teleport daemon binary (written in Go) and a web UI written in Javascript (a git submodule located in the webassets/ directory).

If your intention is to build and deploy for use in a production infrastructure a released tag should be used. The default branch, master, is the current development branch for an upcoming major version. Get the latest release tags listed at https://goteleport.com/download/ and then use that tag in the git clone. For example git clone https://github.com/gravitational/teleport.git -b v9.1.2 gets release v9.1.2.

Dockerized Build

It is often easiest to build with Docker, which ensures that all required tooling is available for the build. To execute a dockerized build, ensure that docker is installed and running, and execute:

make -C build.assets build-binaries

Local Build

Dependencies

Ensure you have installed correct versions of necessary dependencies:

• Go version from go.mod
• If you wish to build the Rust-powered features like Desktop Access, see the Rust and Cargo version in build.assets/Makefile (search for RUST_VERSION)
• For tsh version > 10.x with FIDO support, you will need libfido and openssl 1.1 installed locally

For an example of Dev Environment setup on a Mac, see [these instructions](BUILD_macos.md).

Perform a build

Important

• The Go compiler is somewhat sensitive to the amount of memory: you will need at least 1GB of virtual memory to compile Teleport. A 512MB instance without swap will not work.
• This will build the latest version of Teleport, regardless of whether it is stable. If you want to build the latest stable release, run git checkout and git submodule update --recursive to the corresponding tag (for example,
• run git checkout v8.0.0) before performing a build.

Get the source

git clone https://github.com/gravitational/teleport.git
cd teleport

To perform a build

make full

To build tsh with Apple TouchID support enabled:

Important

tsh binaries with Touch ID support are only functional using binaries signed with Teleport's Apple Developer ID and notarized by Apple. If you are a Teleport maintainer, ask the team for access.

make build/tsh TOUCHID=yes

To build tsh with libfido:

  make build/tsh FIDO2=dynamic

• On a Mac, with libfido and openssl 1.1 installed via homebrew

  export PKG_CONFIG_PATH="$(brew --prefix [email protected])/lib/pkgconfig"
  make build/tsh FIDO2=dynamic
  

Build output and running locally

If the build succeeds, the installer will place the binaries in the build directory.

Before starting, create default data directories:

sudo mkdir -p -m0700 /var/lib/teleport
sudo chown $USER /var/lib/teleport

Web UI

The Teleport Web UI resides in the Gravitational Webapps repo.

Rebuilding Web UI for development

To clone this repository and rebuild the Teleport UI package, run the following commands:

git clone [email protected]:gravitational/webapps.git
cd webapps
make build-teleport

Then you can replace Teleport Web UI files with the files from the newly-generated /dist folder.

To enable speedy iterations on the Web UI, you can run a local web-dev server.

You can also tell Teleport to load the Web UI assets from the source directory. To enable this behavior, set the environment variable DEBUG=1 and rebuild with the default target:

# Run Teleport as a single-node cluster in development mode:
DEBUG=1 ./build/teleport start -d

Keep the server running in this mode, and make your UI changes in /dist directory. For instructions about how to update the Web UI, read the webapps README file.

Updating Web UI assets

After you commit a change to the webapps repo, you need to update the Web UI assets in the webassets/ git submodule.

Run make update-webassets to update the webassets repo and create a PR for teleport to update its git submodule.

You will need to have the gh utility installed on your system for the script to work. For installation instructions, read the GitHub CLI installation documentation.

Managing dependencies

All dependencies are managed using Go modules. Here are the instructions for some common tasks:

Add a new dependency

Latest version:

go get github.com/new/dependency

and update the source to use this dependency.

To get a specific version, use go get github.com/new/dependency@version instead.

Set dependency to a specific version

go get github.com/new/dependency@version

Update dependency to the latest version

go get -u github.com/new/dependency

Update all dependencies

go get -u all

Debugging dependencies

Why is a specific package imported?

go mod why $pkgname

Why is a specific module imported?

go mod why -m $modname

Why is a specific version of a module imported?

go mod graph | grep $modname

Why did We Build Teleport?

The Teleport creators used to work together at Rackspace. We noticed that most cloud computing users struggle with setting up and configuring infrastructure security because popular tools, while flexible, are complex to understand and expensive to maintain. Additionally, most organizations use multiple infrastructure form factors such as several cloud providers, multiple cloud accounts, servers in colocation, and even smart devices. Some of those devices run on untrusted networks, behind third-party firewalls. This only magnifies complexity and increases operational overhead.

We had a choice, either start a security consulting business or build a solution that's dead-easy to use and understand. A real-time representation of all of your servers in the same room as you, as if they were magically teleported. Thus, Teleport was born!
