The image is available on cgr.dev:

docker pull cgr.dev/chainguard/teleport:latest

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

2. 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

3. 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

Note: As Chainguard provides only :latest tag for public images you cannot use the :latest tag for teleportVersionOverride variable as its only accepts semver type of version number. Due to that limitation you should clone this image with semver tag and use it in the helm install command. https://github.com/gravitational/teleport/blob/1e92d5e90223fc69ca75d00da4c350808dc56c2a/examples/chart/teleport-cluster/charts/teleport-operator/templates/_helpers.tpl#L38-L40 Or you could use helm –version X for Teleport version.
