4.3.0

This is a major Teleport release with a focus on new features, functionality, and bug fixes. It’s a substantial release and users can review 4.3 closed issues on Github for details of all items. We would love your feedback - please pick a time slot for a remote UX feedback session if you’re interested.

New Features

Web UI

Teleport 4.3 includes a completely redesigned Web UI. The new Web UI expands the management functionality of a Teleport cluster and the user experience of using Teleport to make it easier and simpler to use. Teleport's new terminal provides a quick jumping-off point to access nodes and nodes on other clusters via the web.

Teleport's Web UI now exposes Teleport’s Audit log, letting auditors and administrators view Teleport access events, SSH events, recording session, and enhanced session recording all in one view.

Teleport Plugins

Teleport 4.3 introduces four new plugins that work out of the box with Approval Workflow. These plugins allow you to automatically support role escalation with commonly used third party services. The built-in plugins are listed below.

Improvements

  • Added the ability for local users to reset their own passwords. #2387
  • Added user impersonation (kube_users) support to Kubernetes Proxy. #3369

Documentation

Upgrade Notes

Always follow the recommended upgrade procedure to upgrade to this version.

New Signing Algorithm

If you’re upgrading an existing version of Teleport, you may want to consider rotating CA to SHA-256 or SHA-512 for RSA SSH certificate signatures. The previous default was SHA-1, which is now considered to be weak against brute-force attacks. SHA-1 certificate signatures are also no longer accepted by OpenSSH versions 8.2 and above. All new Teleport clusters will default to SHA-512 based signatures. To upgrade an existing cluster, set the following in your teleport.yaml:

teleport:
    ca_signature_algo: "rsa-sha2-512"

Rotate the cluster CA, following these docs.

Web UI

Due to the number of changes included in the redesigned Web UI, some URLs and functionality have shifted. Refer to the following ticket for more details. #3580

RBAC for Audit Log and Recorded Sessions

Teleport 4.3 has made the audit log accessible via the Web UI. Enterprise customers can limit access by changing the options on the new event resource.

# list and read audit log, including audit events and recorded sessions
- resources: [event]
  verbs: [list, read]
Kubernetes Permissions

The minimum set of Kubernetes permissions that need to be granted to Teleport proxies has been updated. If you use the Kubernetes integration, please make sure that the ClusterRole used by the proxy has sufficient permissions.

Path prefix for etcd

The etcd backend now correctly uses the “prefix” config value when storing data. Upgrading from 4.2 to 4.3 will migrate the data as needed at startup. Make sure you follow our Teleport upgrade guidance.

Note: If you use an etcd backend with a non-default prefix and need to downgrade from 4.3 to 4.2, you should backup Teleport data and restore it into the downgraded cluster.

New Features

Teleport for IoT

With Teleport 4.0, nodes gain the ability to use reverse tunnels to dial back to a Teleport cluster to bypass firewall restrictions. This allows connections even to nodes that a cluster does not have direct network access to. Customers that have been using Trusted Clusters to achieve this can now utilize a unified interface to access all nodes within their infrastructure.

FedRamp Compliance

With this release of Teleport, we have built out the foundation to help Teleport Enterprise customers build and meet the requirements in a FedRAMP System Security Plan (SSP). This includes a FIPS 140-2 friendly build of Teleport Enterprise as well as a variety of improvements to aid in complying with security controls even in FedRAMP High environments.

Improvements

Bug Fixes

  • Switched to xdg-open to open a browser window on Linux. #2536
  • Increased SSO callback timeout to 180 seconds. #2533
  • Set permissions on TTY similar to OpenSSH. #2508

The lists of improvements and bug fixes above mention only the significant changes, please take a look at the complete list on Github for more.

Upgrading

Teleport 4.0 is backwards compatible with Teleport 3.2 and later. Follow the recommended upgrade procedure to upgrade to this version.

Note that due to substantial changes between Teleport 3.2 and 4.0, we recommend creating a backup of the backend datastore (DynamoDB, etcd, or dir) before upgrading a cluster to Teleport 4.0 to allow downgrades.

Notes on compatibility

Teleport has always validated host certificates when a client connects to a server, however prior to Teleport 4.0, Teleport did not validate the host the user requests a connection to is in the list of principals on the certificate. To ensure a seamless upgrade, make sure the hosts you connect to have the appropriate address set in public_addr in teleport.yaml before upgrading.

This release of Teleport brings new features, significant performance and usability improvements as well usual bugfixes.

During this release cycle, the Teleport source code has been audited for security vulnerabilities by Cure53 and this release (2.6.0) contains patches for the discovered problems.

New Features

  • Support for DynamoDB for storing the audit log events. #1755
  • Support for Amazon S3 for storing the recorded SSH sessions. #1755
  • Support for rotating certificate authorities (CA rotation). [#1899] (gravitational#1899)
  • Integration with Linux PAM (pluggable authentication modules) subsystem. #742 and #1766
  • The new CLI command tsh status shows users which Teleport clusters they are authenticated with. #1628

Additionally, Teleport 2.6.0 has been submitted to the AWS marketplace. Soon AWS users will be able to create properly configured, secure and highly available Teleport clusters with ease.

Configuration Changes

  • Role templates (depreciated in Teleport 2.3) were fully removed. We recommend migrating to role variables which are documented here

  • Resource names (like roles, connectors, trusted clusters) can no longer contain unicode or other special characters. Update the names of all user created resources to only include characters, hyphens, and dots.

  • advertise_ip has been deprecated and replaced with public_addr setting. See #1803 The existing configuration files will still work, but we advise Teleport administrators to update it to reflect the new format.

  • Teleport no longer uses boltdb back-end for storing cluster state by default. The new default is called dir and it uses simple JSON files stored in /var/lib/teleport/backend. This change applies to brand new Teleport installations, the existing clusters will continue to use boltdb.

  • The default set of enabled cryptographic primitives has been updated to reflect the latest state of SSH and TLS security. #1856.

2.5.0

This is a major release of Teleport. Its goal is to make cloud-native deployments easier. Numerous AWS users have contributed feedback to this release, which includes:

New Features

  • Auth servers in highly available (HA) configuration can share the same /var/lib/teleport data directory when it's hosted on NFS (or AWS EFS). #1351

  • There is now an AWS reference deployment in examples/aws directory. It uses Terraform and demonstrates how to deploy large Teleport clusters on AWS using best practices like auto-scaling groups, security groups, secrets management, load balancers, etc.

  • The Teleport daemon now implements built-in connection draining which allows zero-downtime upgrades. See documentation.

  • Dynamic join tokens for new nodes can now be explicitly set via tctl node add --token. This allows Teleport admins to use an external mechanism for generating cluster invitation tokens. #1615

  • Teleport now correctly manages certificates for accessing proxies behind a load balancer with the same domain name. The new configuration parameter public_addr must be used for this. #1174.

Improvements

  • Switching to a new TLS-based auth server API improves performance of large clusters. #1528

  • Session recordings are now compressed by default using gzip. This reduces storage requirements by up to 80% in our real-world tests. #1579

  • More user-friendly authentication errors in Teleport audit log helps Teleport admins troubleshoot configuration errors when integrating with SAML/OIDC providers. #1554, #1553, #1599

  • tsh client will now report if a server's API is no longer compatible.

Bug Fixes

  • tsh logout will now correctly log out from all active Teleport sessions. This is useful for users who're connected to multiple Teleport clusters at the same time. #1541

  • When parsing YAML, Teleport now supports -- list item separator to create multiple resources with a single tctl create command. #1663

  • Fixed a panic in the Web UI backend #1558

Behavior Changes

Certain components of Teleport behave differently in version 2.5. It is important to note that these changes are not breaking Teleport functionality. They improve Teleport behavior on large clusters deployed on highly dynamic cloud environments such as AWS. This includes:

  • Session list in the Web UI is now limited to 1,000 sessions.
  • The audit log and recorded session storage has been moved from /var/lib/teleport/log to /var/lib/teleport/log/<auth-server-id>. This is related to #1351 described above.
  • When connecting a trusted cluster users can no longer pick an arbitrary name for them. Their own (local) names will be used, i.e. the cluster_name setting now defines how the cluster is seen from the outside. #1543
