Introduction

Teleport includes an identity-aware access proxy, a CA that issues short-lived certificates, a unified access control system and a tunneling system to access resources behind the firewall.

We have implemented Teleport as a single Go binary that integrates with multiple protocols and cloud services:

You can set up Teleport as a Linux daemon or a Kubernetes deployment.

Teleport focuses on best practices for infrastructure security:

Teleport uses Go crypto. It is fully compatible with OpenSSH, sshd servers, and ssh clients, Kubernetes clusters and more.

Follow our guide to registering your first server with Teleport Enterprise Cloud.

Docker

Deploy Teleport

If you wish to deploy Teleport inside a Docker container see the installation guide.

For Local Testing and Development

Follow the instructions in the docker/README file.

To run a full test suite locally, see the test dependencies list

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 v16.0.0 gets release v16.0.0.

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:

For an example of Dev Environment setup on a Mac, see these instructions.

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

tsh dynamically links against libfido2 by default, to support development environments, as long as the library itself can be found:

$ brew install libfido2 pkg-config  # Replace with your package manager of choice

$ make build/tsh
> libfido2 found, setting FIDO2=dynamic
> (...)

Release binaries are linked statically against libfido2. You may switch the linking mode using the FIDO2 variable:

make build/tsh FIDO2=dynamic # dynamic linking
make build/tsh FIDO2=static  # static linking, for an easy setup use `make enter`
                             # or `build.assets/macos/build-fido2-macos.sh`.
make build/tsh FIDO2=off     # doesn't link libfido2 in any way

Build output and run 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

Running Teleport in a hot reload mode

To speed up your development process, you can run Teleport using CompileDaemon. This will build and run the Teleport binary, and then rebuild and restart it whenever any Go source files change.

  1. Install CompileDaemon:

    go install github.com/githubnemo/CompileDaemon@latest

    Note that we use go install instead of the suggested go get, because we don't want CompileDaemon to become a dependency of the project.

  2. Build and run the Teleport binary:

    make teleport-hot-reload

    By default, this runs a teleport start command. If you want to customize the command, for example by providing a custom config file location, you can use the TELEPORT_ARGS parameter:

    make teleport-hot-reload TELEPORT_ARGS='start --config=/path/to/config.yaml'

Note that you still need to run make grpc if you modify any Protocol Buffers files to regenerate the generated Go sources; regenerating these sources should in turn cause the CompileDaemon to rebuild and restart Teleport.

Web UI

The Teleport Web UI resides in the web directory.

Rebuilding Web UI for development

To rebuild the Teleport UI package, run the following command:

make docker-ui

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 web README.

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

Devbox Build (experimental)

Note: Devbox support is still experimental. It's very possible things may not work as intended.

Teleport can be built using devbox. To use devbox, follow the instructions to install devbox here and then run:

devbox shell

This will install Teleport's various build dependencies and drop you into a shell with these dependencies. From here, you can build Teleport normally.

flake.nix

A nix flake is located in build.assets/flake that allows for installation of Teleport's less common build tooling. If this flake is updated, run:

devbox install

in order to make sure the changes in the flake are reflected in the local devbox shell.

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!
