Chainguard Image for teleport

Teleport is an access management platform designed to provide secure and unified access to various infrastructure resources such as SSH, Kubernetes clusters, databases, and web applications

Chainguard Images are regularly-updated, minimal container images with low-to-zero CVEs.

Download this Image

This image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/teleport:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard registry.

Usage

There are several ways of installing and configuring Teleport. To access the whole available installation methods and configurations, visit the Teleport Installation documentation.

For example this guide shows how to run Teleport in a Docker container: https://goteleport.com/docs/installation/#example-of-running-a-teleport-container

  1. Run teleport configure from the Teleport container to generate a configuration file. This sets the container's name to localhost so your browser can trust the Proxy Service's self-signed TLS certificate:
docker run --hostname localhost --rm \
  --entrypoint=/usr/local/bin/teleport \
  cgr.dev/chainguard/teleport:latest configure --roles=proxy,auth > ~/teleport/config/teleport.yaml
  1. Start the Teleport container:
docker run --hostname localhost --name teleport \
  -v ~/teleport/config:/etc/teleport \
  -v ~/teleport/data:/var/lib/teleport \
  -p 3025:3025 -p 3080:3080 \
  cgr.dev/chainguard/teleport:latest
  1. From there, open another terminal and make sure your Teleport container's web API is functioning as intended:
curl --insecure https://localhost:3080/webapi/ping

You should see JSON output similar to the following:

{
  "auth": {
    "type": "local",
    "second_factor": "otp",
    "preferred_local_mfa": "otp",
    "local": {
      "name": ""
    },
    "private_key_policy": "none",
    "device_trust_disabled": true,
    "has_motd": false
  },
  "proxy": {
    "kube": {
      "enabled": true,
      "listen_addr": "0.0.0.0:3080"
    },
    "ssh": {
      "listen_addr": "0.0.0.0:3080",
      "tunnel_listen_addr": "0.0.0.0:3080",
      "web_listen_addr": "0.0.0.0:3080"
    },
    "db": {
      "postgres_listen_addr": "0.0.0.0:3080",
      "mysql_listen_addr": "0.0.0.0:3080"
    },
    "tls_routing_enabled": true
  },
  "server_version": "12.1.5",
  "min_client_version": "11.0.0",
  "cluster_name": "localhost",
  "automatic_upgrades": false
}

Also you could install Teleport on Kubernetes using Helm. For more information, visit the Teleport Helm Chart documentation.

All you need to do is to add the Helm repository and install the Teleport Helm chart:

helm repo add teleport https://charts.releases.teleport.dev
helm repo update

Then install the Teleport Helm chart:

helm install teleport-cluster teleport/teleport-cluster \
  --create-namespace \
  --version 15.4.0 \
  --set image=cgr.dev/chainguard/teleport

What are Chainguard Images?

Chainguard Images are a collection of container images designed for security and minimalism.

Many Chainguard Images are distroless; they contain only an open-source application and its runtime dependencies. These images do not even contain a shell or package manager. Chainguard Images are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a secure software supply chain.

The main features of Chainguard Images include:

-dev Variants

As mentioned previously, Chainguard’s distroless Images have no shell or package manager by default. This is great for security, but sometimes you need these things, especially in builder images. For those cases, most (but not all) Chainguard Images come paired with a -dev variant which does include a shell and package manager.

Although the -dev image variants have similar security features as their distroless versions, such as complete SBOMs and signatures, they feature additional software that is typically not necessary in production environments. The general recommendation is to use the -dev variants only to build the application and then copy all application artifacts into a distroless image, which will result in a final container image that has a minimal attack surface and won’t allow package installations or logins.

That being said, it’s worth noting that -dev variants of Chainguard Images are completely fine to run in production environments. After all, the -dev variants are still more secure than many popular container images based on fully-featured operating systems such as Debian and Ubuntu since they carry less software, follow a more frequent patch cadence, and offer attestations for what they include.
