Management Plane Installation

This page will show you how to install the Tetrate Service Bridge management plane in a production environment.

Before you start, make sure that you've:

✓ Checked the requirements
✓ Checked TSB management plane components
✓ Checked types of certificates and internal certificates requirements
✓ Checked firewall information
✓ If you are upgrading from previous version, also check PostgreSQL backup and restore
✓ Downloaded Tetrate Service Bridge CLI (tctl)
✓ Synced the Tetrate Service Bridge images

Management Plane Operator​

To keep installation simple but still allow a lot of custom configuration options we have created a management plane operator. The operator will run in the cluster and bootstraps the management plane as described in a ManagementPlane Custom Resource. It watches for changes and enacts them. To help in creating the right Custom Resource Document (CRD) we have added the ability to our tctl client to create the base manifests which you can then modify according to your required set-up. After this you can either apply the manifests directly to the appropriate clusters or use in your source control operated clusters.

Operators

If you would like to know more about the inner workings of Operators, and the Operator Pattern, review the Kubernetes documentation

Create the manifest allowing you to install the management plane operator from your private Docker registry:

tctl install manifest management-plane-operator \
  --registry <registry-location> > managementplaneoperator.yaml

The managementplaneoperator.yaml file created by the install manifest command can be applied directly to the appropriate cluster by using the kubectl client:

kubectl apply -f managementplaneoperator.yaml

After applying the manifest you will see the operator running in the tsb namespace:

kubectl get pod -n tsb

Example output:

NAME                                            READY   STATUS    RESTARTS   AGE
tsb-operator-management-plane-d4c86f5c8-b2zb5   1/1     Running   0          8s

Configuring Secrets​

The management plane components need some secrets for both internal and external communication purposes. Following are a list of secrets that you need to create.

Secret nameDescription
admin-credentialsTSB will create a default admin user with name: admin and this is the password's one way hash for this special account. These credentials are kept outside of your IdP while any other credentials must be stored in your IdP.
tsb-certsTLS certificate that has type kubernetes.io/tls. Must have tls.key and tls.cert value. The TLS certificates can be self signed or issued by public CA.
postgres-credentialsContains:
 1. Postgres username and password.
 2. The CA certificate to verify Postgres connections when Postgres is configured to present a self-signed certificate. TLS verification only happens if you set sslMode in Postgres settings to verify-ca or verify-full. See PostgresSettings for more details.
 3. Client certificate and private key if Postgres is configured with mutual TLS.
elastic-credentialsElasticsearch username and password.
es-certsThe CA certificate to validate Elasticsearch connections when Elasticsearch is configured to present a self-signed certificate.
ldap-credentialsOnly set if using LDAP as Identity Provider (IdP). Contain LDAP binddn and bindpassword.
custom-host-caOnly set if using LDAP as IdP. The CA certificate to validate LDAP connections when LDAP is configured to present a self-signed certificate.
iam-oidc-client-secretOnly set if using OIDC with any IdP. Contain OIDC client-secret and device-client-secret.
azure-credentialsOnly set if using OIDC with Azure AD as IdP. Client secret to connect to Azure AD for team and user synchronization.
xcp-central-certXCP central mTLS or TLS certificate. The requirement of this secret is depend on whether you use mTLS or JWT with TLS for XCP authentication. Go to Internal certificate requirements for more details.
mpc-certsOnly set if using mTLS for XCP authentication. Go to Internal certificate requirements for more details.

Using tctl to Generate Secrets​

These secrets can be generated in the correct format by passing them as command-line flags to the tctl management-plane-secrets command.

XCP central certificate with cert-manager

In case you have installed cert-manager in the management plane cluster, you can have tctl automatically provision certificates for secure communication with control planes. To do this, add an --xcp-certs flag to the install manifest management-plane-secrets command. This will create a certificate Issuer along with xcp-central-cert and mpc-certs certificates.

The following command will generate managementplane-secrets.yaml that contains Elasticsearch, Postgres, OIDC and admin credentials along with TSB TLS certificate.

tctl install manifest management-plane-secrets \
    --elastic-password <elastic-password> \
    --elastic-username <elastic-username> \
    --oidc-client-secret "<oidc-client-secret>" \
    --postgres-password <postgres-password> \
    --postgres-username <postgres-username> \
    --tsb-admin-password <tsb-admin-password> \
    --tsb-server-certificate "$(cat foo.cert)" \
    --tsb-server-key "$(cat foo.key)" > managementplane-secrets.yaml

See the CLI reference documentation for all available options such as providing CA certificates for Elasticsearch, PostgreSQL and LDAP. You can also check the bundled explanation from tctl by running this help command:

tctl install manifest management-plane-secrets --help

Applying secrets​

Once you've created your secrets manifest, you can add to source control or apply it to your cluster.

Vault Injection

If you're using Vault injection for certain components, remove the applicable secrets from the manifest that you've created before applying it to your cluster.

kubectl apply -f managementplane-secrets.yaml

Management Plane Installation​

Now you're ready to deploy the management plane.

To deploy the management plane you need to create a ManagementPlane custom resource in the Kubernetes cluster that describes the management plane.

Organization name

Organization is a root of the TSB object hierarchy. A TSB Management plane can only have one organization.

To login with tctl, you will need to specify organization name and it must match with <organization-name> that you set in the ManagementPlane CR below. Organization name has to be lowercase to comply with RFC standards.

If not specified, the default value is tetrate and it cannot be changed after creation.

Below is a ManagementPlane custom resource (CR) that describes a basic management plane. Save this managementplane.yaml and adjust it according to your needs:

XCP authentication

Starting TSB 1.5, default authentication method for XCP central and edge traffic is JWT. If you want to keep using mTLS you have to set spec.components.xcp.centralAuthModes.mutualTls to true. To migrate from mTLS to JWT follow steps described in here

About ES selfsigned certs

If you are using selfsigned certs for ES, you may encounter an issue with oap pod and oap-deployment not able to start. To solve this, provide a certificate signed by a well known Certificate Authority and set selfSigned: false in the ManagementPlane CR. If your organization acts a signer, then you will need to give the pods privileged access in the container security context.

The following example uses OIDC as identity provider.

apiVersion: install.tetrate.io/v1alpha1
kind: ManagementPlane
metadata:
  name: managementplane
  namespace: tsb
spec:
  hub: <registry-location>
  organization: <organization-name>
  dataStore:
    postgres:
      host: <postgres-hostname-or-ip>
      port: <postgres-port>
      name: <database-name>
  telemetryStore:
    elastic:
      host: <elastic-hostname-or-ip>
      port: <elastic-port>
      version: <elastic-version>
      selfSigned: <is-elastic-use-self-signed-certificate>
      protocol: <http or https. default to https if not set>
  identityProvider:
    oidc:
      clientId: <oidc-client-id>
      # authorization code flow for TSB UI login
      providerConfig:
        dynamic:
          configurationUri: <oidc-well-known-openid-configuration>
      redirectUri: <oidc-callback>
      scopes:
      - email
      - profile
      - offline_access
  # Customize token issuer to use signing key that you have created before.
  tokenIssuer:
    jwt:
      expiration: 1h
      issuers:
      - name: https://jwt.tetrate.io
        # Signing key stored in Kubernetes secret.
        signingKey: private.key
      # Kubernetes secret name where you store IAM signing key.
      signingKeysSecret: iam-signing-key
  components:
    internalCertProvider:
      certManager:
        managed: INTERNAL

If you are not using Azure AD an the OIDC Identity provider, follow the steps in Users Synchronization to see how you can create organizations and sync your users and teams into TSB

For more information on what each of these sections describes and how to configure them, please check out the following links:

Edit the relevant sections, save your configured custom resource to a file and apply it to your Kubernetes cluster.

kubectl apply -f managementplane.yaml

Note: TSB will automatically do this every hour, so this command only needs to be run once after the initial installation.

Verifying Installation​

To verify your installation succeeded, log in as the admin user. Try to connect to the TSB UI or login with the tctl CLI tool.

The TSB UI is reachable on port 8443 of the external IP as returned by the following command:

kubectl get svc -n tsb envoy

To configure tctl's default config profile to point to your new TSB cluster do the following:

tctl config clusters set default --bridge-address $(kubectl get svc -n tsb envoy --output jsonpath='{.status.loadBalancer.ingress[0].ip}'):8443

Now you can log in with tctl and provide the organization name and admin account credentials. The tenant field is optional and can be left blank at this point and configured later, when tenants are added to the platform.

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

Go to Connect to TSB with tctl for more details on how to configure tctl.
