Introduction

Gravitational Teleport ("Teleport") is a tool for remotely accessing isolated clusters of Linux servers via SSH or HTTPS.

Unlike traditional key-based access, Teleport enables teams to easily adopt the following practices:

  • Avoid key distribution and trust on first use issues by using auto-expiring keys signed by a cluster certificate authority (CA).
  • Enforce 2nd factor authentication.
  • Connect to clusters located behind firewalls without direct Internet access via SSH bastions.
  • Record and replay SSH sessions for knowledge sharing and auditing purposes.
  • Collaboratively troubleshoot issues through session sharing.
  • Discover online servers and Docker containers within a cluster with dynamic node labels.

Teleport is built on top of the high-quality Golang SSH implementation and it is fully compatible with OpenSSH.

Installing and Running

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

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

teleport start

Building Teleport

You need to have Golang v1.5 or newer.

Clone this repository into $GOPATH/gravitational/teleport and run make.

You'll have to create /var/lib/teleport directory and then you can start Teleport as a single-node cluster in development mode: build/teleport start -d

If you want to release your own Teleport version, edit this Makefile, update VERSION and SUFFIX constants, then run make setver to update version.go

If you want to cut another binary release tarball, run make release.

NOTE: The Go compiler is somewhat sensitive to amount of memory: you will need at least 1GB of virtual memory to compile Teleport. 512MB instance without swap will not work.

Why did We Build Teleport?

Mature tech companies with significant infrastructure footprints tend to implement most of these patterns internally. Teleport allows smaller companies without significant in-house SSH expertise to easily adopt them, as well. Teleport comes with an accesible Web UI and a very permissive Apache 2.0 license to facilitate adoption and use.

Being a complete standalone tool, Teleport can be used as a software library enabling trust management in complex multi-cluster, multi-region scenarios across many teams within multiple organizations.

Status

Teleport is not ready to be used in production yet. Teleport is undergoing a comprehensive independent security audit.

Who Built Teleport?

Teleport was created by Gravitational Inc. We have built Teleport by borrowing from our previous experiences at Rackspace. It has been extracted from Gravity, our system for helping our clients to deploy and remotely manage their SaaS applications on many cloud regions or even on-premise.
