Release Notes for v1.3.2​

Breaking Changes​

  • Before upgrading, ensure existing Codezero instance is fully stopped (run czctl stop)

Release Notes for v1.2.2​

Features​

  • Check for git repository root when creating development profiles [#2413]
  • Enable Desktop application's ability to auto-launch the Codezero daemon.
  • Prompt user if namespace is missing, rather than throw an error.

Release Notes for v1.2.1​

BREAKING CHANGES​

  • Close the existing Codezero background process before upgrading (czctl stop). In case of issues, the old background service can be shutdown using: sudo npx pm2 kill.

Features​

Release Notes for v1.2.0​

BREAKING CHANGES​

  • Please use czctl start instead of sudo czctl init when starting up the CLI. The start command does not need to be run with sudo explicitly, as the command will prompt you for your password if permission elevation is required.

New Features​

  • This release introduces a daemon service on your local machine to manage the long-running session (in preparation for [#21]).
  • Added czctl start and czctl stop commands (init is now an alias of start) to manage the daemon's lifecycle.
  • Volume mount command: now works on Linux without sudo. [#25]
  • Auto-Restart interceptor tunnel to avoid tunnel timeout. [#26]
  • sudo is no longer required to start up the CLI. [#23]
  • Added --save-profile flag to teleport, intercept and mount commands to prepare for use of Development Profiles.

Bug Fixes​

  • Fixed podless services with no endpoint causing crash
  • Fixed issue when registering configuration watcher
  • Fixed intercept session cleanup on close
  • Fixed NVM environments unable to reliably initialize the CLI [#23]

Note (Known Issue): Intercept currently does NOT work with Node 17.x on macOS. [#24]

Release Notes for v1.1.1​

Bug Fixes​

  • Update package.json "pack" script to avoid conflict with brew installation (#2071)

Release Notes for v1.1.0​

New Features​

  • Volume mount command: You can now mount persistent volumes that any workload has mounted: czctl [workload] mount [workload name] [mount root] -n [namespace] Where the workload is cronjob, deployment, job, pod, or statefulset (Mounting all volumes in a namespace is not supported), the workload name is the name of the workload, the mount root is a local directory where the volumes should be mounted, and the namespace is the namespace where the workload resides.

Note: On Linux: you will need to use sudo -E to run the czctl workload mount command.

Note: On first read or write to a mounted volume there will be a delay, but on subsequent writes performance will be improved.

Note: Make sure you have a teleport session open before using the mount command: czctl [workload] teleport [workload name] -n [namespace]

Note (Known Issue): If you have mounted some volumes, do not use czctl session close --all as this will close teleport before trying to unmount volumes. If you end up in this state, re-teleport and explicitly close the mount session first and then the teleport session.

Release Notes for v1.0.4​

New Features​

  • Support for intercepting all traffic (#1997)

Bug Fixes​

  • Environment monitor now checks process rather than the file to determine if a session is open (#2000)

Release Notes for v1.0.3​

Bug Fixes​

  • Increased timeouts for pod-less decoy (#1982)

Release Notes for v1.0.2​

Bug Fixes​

New Features​

  • Support teleporting to headless and podless services

Known Issues​

  • Cannot intercept a headless and podless service

Release Notes for v0.2.8​

New Features​

  • Support for headless services
  • Increase the timeout of the teleport tunneller.
  • Stability Improvements

Release Notes for v0.2.7​

BREAKING CHANGES​

  • Any scripting that assumes that all namespaces will be teleported needs to be modified to use the new flags to add namespaces other than the one being referenced in the teleport command. The --all flag allows you to connect to all namespaces. You can also add more namespaces with additional -a namespace1 -a namespace2

Bug Fixes​

  • Fix for teleport cleanup

Migration notes from v0.2.6 to v0.2.7​

To upgrade from 0.2.6 to 0.2.7 you will need to:

  1. Close your current sessions: czctl session close --all
  2. Restore your /etc/hosts and remove the Kubernetes services referenced there. You can copy ~/hosts.original to /etc/hosts or edit the /etc/hosts file directly using sudo. Make sure that ~/hosts.original is correct before using it to restore things using sudo cp ~/hosts.original /etc/hosts. If the hosts.original files is not correct, then edit the /etc/hosts file directly (use sudo to edit this file with your favourite editor: sudo vi /etc/hosts
  3. Remove ~/hosts.original

You can do this before or after installing the new @c6o/cli version 0.2.7: npm update -g @c6o/cli, npm install -g @c6o/cli@0.2.7 or npm install -g @c6o/cli@latest

To make sure you have the right version, use czctl version . The output should look something like this:

> czctl version
@c6o/cli/0.2.7 darwin-arm64 node-v16.2.0

Release Notes for v0.2.6​

BREAKING CHANGES​

  • There are changes to the teleport binary that need to be applied, so existing users MUST re-run sudo czctl init.

Bug Fixes​

  • Fix error messaging to users of unsupported Node versions (less than 13.x)
  • Fixed some czctl deployment arguments not being properly recognized [#1834, #1837]

New Features​

  • Teleport provides feedback to the user once all connections are fully setup [#1766, #1827]
  • Teleport auto-detects when new intercepts are added/removed, so restart is no longer required [#1808]
  • Extended teleport to work with other workloads (pods, cronjobs, jobs, statefulsets) [#1778]

Outstanding Issues​

  • NodesJS < 13.x is not supported.
  • Cannot intercept more than 4 services simultaneously from the same machine.
  • Cannot teleport to headless services yet

[!WARNING] We expect the cli commands to change in the next release. We are considering reversing the commands from <resource> <action> to <action> <resource> and dropping the term intercept. For instance, you will run: czctl teleport deployment ... and czctl teleport service ... and the parameters will change depending on the resource. We may also use a generic term like connect so as not to confuse our tool with tools like goteleport.com.

Release Notes for v0.2.5​

BREAKING CHANGES​

  • czctl service intercept port flags changed. -p is now -r for remote and -o is now -l for local.
  • We have removed having to run sudo each time you teleport. Now, after installing the CLI, a user must run sudo czctl init once and from then on, sudo is no longer required. [#1744]

Bug Fixes​

  • Fix Teleport hanging forever on Node 14.x
  • Fix Teleport environment file flag to support absolute paths.
  • Fix intercept's ngrok tunnels closing unexpectedly.
  • Fix various CLI error messages and suggestions to display more useful information.
  • Fix namespaces and service names being passed through and displayed as 'undefined'

New Features​

  • Support multiple users intercepting the same service(s). Requires users to use the same header key but different values. [#1711, #1757]
  • Cluster based session management, so user can list and clean up sessions created by other users. [#1688]
  • Allow intercepting up to 4 services simultaneously per machine. [#1783]
  • sudo -E is no longer required for czctl teleport. [#1744]
  • Teleport no longer requires the environment file flag (-f).

Outstanding Issues​

  • NodesJS less than 13.x is not supported.
  • Cannot intercept more than 4 services simultaneously from the same machine.
  • Teleport must be run after all intercepts. Please stop and run teleport after any czctl service intercept calls to take the new intercept into account locally.
  • Teleport should provide feedback to the user, so they know when all services have been fully setup.
