Connect to TSB with tctl

In this page you'll learn to connect to TSB with the tctl CLI and some basics of using the CLI.

Before you start:
Install the TSB management plane (On-Premise Only)
Download Tetrate Service Bridge CLI (tctl)
✓ Get your TSB's organization name - you can find this logging in to the TSB UI.

TSB provides a UI, but most examples in this site - and most scripting and automation - will use the tctl CLI. This document will cover how to get logged in so you can use the CLI, as well as steps to update your credentials.

Overview

There are three ways to configure tctl: using tctl login, downloading the a credential bundle from the UI, or to manually configure it. Each method is described in detail in the rest of this document.

  1. The preferred method is connecting to TSB with tctl login, using the default profile:
tctl config clusters set default --bridge-address $TSB_ADDRESS
tctl login
Organization: tetrate
Tenant:
Username: admin
Password: *****
Login Successful!
# We're ready to go:
tctl get tenants
Output
NAME          DISPLAY NAME    DESCRIPTION
tetrate Tetrate Default tenant
  1. A second easy way to connect with tctl is to download the bundle from the TSB UI and tctl config import it:
tctl config profiles import ~/Downloads/tctl-<your username>.config.yaml
tctl config profiles set-current <your username>-tsb
# We're ready to go:
tctl get tenants
Output
NAME          DISPLAY NAME    DESCRIPTION
tetrate Tetrate Default tenant
  1. And finally you can create your own user, cluster, and profile (with slightly different flags for LDAP vs OIDC) to log in:
tctl config clusters set tsb-how-to-cluster --bridge-address $TSB_ADDRESS
# For OIDC
tctl config users set tsb-how-to-user --org $TCTL_LOGIN_ORG --token $TSB_BEARER_TOKEN --refresh-token $TSB_REFRESH_TOKEN
# Or for LDAP
# tctl config users set tsb-how-to-user --org $TCTL_LOGIN_ORG --username $TCTL_LOGIN_USERNAME --password $TCTL_LOGIN_PASSWORD
tctl config profiles set tsb-how-to --cluster tsb-how-to-cluster --username tsb-how-to-user
tctl config profiles set-current tsb-how-to
# We're ready to go:
tctl get tenants
Output
NAME          DISPLAY NAME    DESCRIPTION
tetrate Tetrate Default tenant

If you logged in with a username and password, you should tctl login to exchange your password for a set of OIDC tokens. After this you can use tctl at will. For example to discover tenants in TSB, simply execute tctl get tenants.

Log in with tctl login

The easiest way to get connected to TSB is to use the tctl login command, which will handle exchanging credentials for OIDC tokens for you, and ensure no plaintext passwords are persisted to disk.

To do this, first we need to configure tctl with the address of our TSB instance. It's easiest to use the default profile for this - if you don't want to use the default profile, skip ahead to the Configure tctl Manually section.

Get TSB's Address

If your kubeconfig is pointed at the management plane cluster, you can get the address from the Kubernetes service:

export TSB_ADDRESS=$(kubectl get svc -n tsb envoy --output jsonpath='{.status.loadBalancer.ingress[0].ip}'):8443

Many organizations will expose TSB's UI (and therefore API) via DNS; you should use that instead of the raw IP address.

Configure the default profile

With TSB's address in hand, we'll configure tctl to connect to it:

tctl config clusters set default --bridge-address $TSB_ADDRESS

Log in with OIDC

To log in with OIDC, we can use the OIDC device code flow, which is built into tctl:

tctl login --use-device-code
Organization: tetrate
Tenant:
Code: GGBD-NJPR
Open browser page https://www.google.com/device and enter the code

Login Successful!
OIDC in the browser

This will open up your browser for you to complete the OIDC login flow and generate tokens.

Log in with Username and Password

Log in, providing your username and password:

tctl login
Organization: tetrate
Tenant:
Username: admin
Password: *****
Login Successful!

Download tctl Config from TSB

tctl works with a config file to connect to a TSB instance, similar to kubeconfig for connecting to a Kubernetes API server. The easiest way to get connected with tctl is to download that config file from the TSB UI, following the instructions in the webpage. To get to those credentials, log in to the TSB UI in your browser, then in the top right corner click on your user name and under select Actions > Show token information > Download tctl Config. This will download a file named tctl-<your username>.config.yaml. You can then import this into tctl, saving it permanently:

tctl config profiles import /path/to/tctl-<your username>.config.yaml
tctl config profiles set-current <your username>-tsb
note

tctl stores configuration in your file system's default configuration directory (as determined by Golang). This would be $HOME/.config/tetrate/tctl/tctl_config on Linux, $HOME/Library/Application\ Support/tetrate/tctl/tctl_config on Darwin, or %AppData%/tetrate/tctl/tctl_config on Windows. This is where your password or tokens would persist. When you import a config file, tctl adds the credentials from that file to the existing credentials in its configuration directory.

Configure tctl Manually

TSB Organization Name

In the examples below, it is assumed that you have saved your organization name saved in the environment variable $TCTL_LOGIN_ORG. If you just completed the demo installation, the demo organization name is tetrate. You can execute the following to save the value in the environment variable: export TCTL_LOGIN_ORG=tetrate.

To log in with tctl, you must first configure a cluster (tctl config clusters), then a user (tctl config users), then combine the two into a profile, which you will be able to use to persist your settings, just like a kubeconfig profile (tctl config profiles set-current ...). With that profile, you can use the tctl login command to configure the credentials and persist to disk any tokens we need to continue to connect to TSB.

Pick a name for your profile

tctl has a default profile just like kubectl which you can use for the commands below, or you can pick your own. For this how-to, create a profile named tsb-how-to (but any name works, including default).

Configure the tctl Cluster

Both the UI and TSB's APIs are exposed on the same address and port. To configure tctl, you will need that address to get started.

Get TSB's Address

If your kubeconfig is pointed at the management plane cluster, you can get the address from the Kubernetes service:

export TSB_ADDRESS=$(kubectl get svc -n tsb envoy --output jsonpath='{.status.loadBalancer.ingress[0].ip}'):8443

Many organizations will expose TSB's UI (and therefore API) via DNS; you should use that instead of the raw IP address.

Create a tctl Cluster

Once you have obtained the address ($TSB_ADDRESS) you can create a cluster in tctl's config. Name the cluster tsb-how-to-cluster:

tctl config clusters set tsb-how-to-cluster --bridge-address $TSB_ADDRESS
tctl Object Names

You could use the same name for the cluster as for the profile itself (e.g. tctl config clusters set tsb-how-to --bridge-address $TSB_ADDRESS). This example uses a different name to make it easier to follow along.

Set tctl's User

First you need to know the username you are logging in with. This will depend on exactly how TSB is installed: if you're using OIDC, this will be your corporate email; if you're using LDAP it'll be your usual LDAP login username; finally you can log in with TSB's default administrative account, if it's not disabled in your installation.

Login for OIDC Users

To log in to TSB with OIDC credentials, log in to the TSB UI in your browser, then in the top right corner click on your user name and under select Actions > Show token information. From that page, copy down the Bearer Token and Refresh Token, exporting them as TSB_BEARER_TOKEN and TSB_REFRESH_TOKEN:

export TSB_BEARER_TOKEN=HHVMW2.qhf9jBL1fMCazBe1umanDr5sNEuFcKtClAUxeWA...redacted
export TSB_REFRESH_TOKEN=AJWXL6VmGUmvYfn43601RG.Bw+xr0IVQ43swidqAt1tHf...redacted
tctl config users set tsb-how-to-user \
--org $TCTL_LOGIN_ORG \
--token $TSB_BEARER_TOKEN \
--refresh-token $TSB_REFRESH_TOKEN

Login for LDAP (username + password) Users

For LDAP logins, you need a username and password; you can configure these and environment variables, or pass them in via the CLI:

export TCTL_LOGIN_USERNAME=demo-user@tetrate.io
export TCTL_LOGIN_PASSWORD=<your password>
tctl config users set tsb-how-to-user \
--org $TCTL_LOGIN_ORG \
--username $TCTL_LOGIN_USERNAME \
--password $TCTL_LOGIN_PASSWORD
Username + Password Logins Write Password to disk

When you configure a user with a username and password, that password is written to disk. To ensure that credential is not saved to disk, you need to tctl login after setting up your cluster, user, and profile.

Login for the Admin User

You can log in as the default administrative user with the same username and password scheme as an LDAP account:

export TCTL_LOGIN_USERNAME=admin # this is hard-coded
export TCTL_LOGIN_PASSWORD=<your password> # you created this during management plane install
tctl config users set tsb-how-to-user \
--org $TCTL_LOGIN_ORG \
--username $TCTL_LOGIN_USERNAME \
--password $TCTL_LOGIN_PASSWORD
warning

It is recommend that you disable the admin user in all deployments of TSB. The primary use case for the admin user is for a platform owner to log in and configure their IdP so the rest of the organization can log in with OIDC or LDAP.

Finally, because this is a username and password login, you need to tctl login to exchange the password for a token for future access and to ensure the password is not saved to disk.

Create your tctl Profile

A profile ties a cluster and a user together so that they can be used to connect to a TSB instance. Connect the cluster and user you just created together into a profile:

tctl config profiles set tsb-how-to --cluster tsb-how-to-cluster --username tsb-how-to-user

Use the new Profile

Configure tctl to use the profile you just created to connect to TSB:

tctl config profiles set-current tsb-how-to

At this point, you're good to go: tctl has TSB's location and your credentials - you can use it to interact with TSB!

Verify the Config

As a sanity check, after finishing the following steps you can list your tctl profiles, and you should see something like:

tctl config profiles list
Output
CURRENT   NAME         CLUSTER             ACCOUNT
default default default
* tsb-how-to tsb-how-to-cluster tsb-how-to-user

Using tctl to find your Tenant

The final bit of setup you can do to make your life easier with tctl is to fill in your tenant, if you have not already done so. Use tctl to ask TSB which tenants exist. For most users, there will be exactly one result returned - which is the tenant you want to be using. For users with multiple tenants, you'll need to talk with your platform team to determine which is the correct to use for you.

tctl get tenants
Output
NAME          DISPLAY NAME    DESCRIPTION
tetrate Tetrate Default tenant

With your tenant in hand, you can save it to your user:

tctl config users set tsb-how-to-user --tenant <your tenant>

Log in with tctl

When you log in with username and password, both are persisted to disk. This is not desirable, as your password is stored in plaintext. To remove the password from tctl's config file, you can use tctl login, which will exchange your credentials for a set of OAuth tokens and write those to disk instead.
