Deployment

In this tutorial you will take on the role of the operations team to deploy Boundary, Vault, and Kubernetes.

Prerequisites

This tutorial requires you to have completed the Connect to Kubernetes using Boundary introduction tutorial.

Deploy Kubernetes

(Persona: operations)

minikube is a CLI tool that provisions and manages the lifecycle of single-node Kubernetes cluster locally on your system.

Deploy a Kubernetes cluser using minikube.

Open a new terminal session.
Create a new working directory in your home directory called boundary-kubernetes to complete the lab exercises. Execute all commands from this working directory unless otherwise specified.
```
$ mkdir ~/boundary-kubernetes && cd ~/boundary-kubernetes/
```

Start a Kubernetes cluster.

$ minikube start😄  minikube v1.25.2 on Darwin 12.3✨  Automatically selected the docker driver. Other choices: hyperkit, virtualbox, ssh👍  Starting control plane node minikube in cluster minikube🚜  Pulling base image ...🔥  Creating docker container (CPUs=2, Memory=8100MB) ...🐳  Preparing Kubernetes v1.23.3 on Docker 20.10.12 ...    ▪ kubelet.housekeeping-interval=5m    ▪ Generating certificates and keys ...    ▪ Booting up control plane ...    ▪ Configuring RBAC rules ...🔎  Verifying Kubernetes components...    ▪ Using image gcr.io/k8s-minikube/storage-provisioner:v5🌟  Enabled addons: storage-provisioner🏄  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

The initialization process takes several minutes as it retrieves any necessary dependencies and executes various container images.

Verify the status of the Minikube cluster.

$ minikube statusminikubetype: Control Planehost: Runningkubelet: Runningapiserver: Runningkubeconfig: Configured

Kubernetes is now set up.

Start a pod that represents a production workload a developer may need to view.
```
$ kubectl run nginx --image=nginxpod/nginx created
```

Deploy Boundary

(Persona: operations)

HashiCorp Boundary is an identity-aware proxy aimed at simplifying and securing least-privileged access to cloud infrastructure.

In this workflow you will test integrating Kubernetes with HCP Boundary.

Launch the HCP Portal and login.
From the Overview page, click Boundary in the left navigation menu.
Click Deploy Boundary.
In the Instance Name text box, provide a name for your Boundary instance.
Under the Create an administrator account section, enter the Username and Password for the initial Boundary administrator account. You will use the administrative username and password to authenticate with Boundary.
Note
The Boundary instance is publicly accessible. Be sure to use a non-standard username (e.g. not root or administrator) and create a strong password.
Click Deploy.
Wait for the instance to initialize before proceeding.
Click the copy icon for the Cluster URL in the Getting started with Boundary section.
Return to the terminal you started Kubernetes in and set the BOUNDARY_ADDR environment variable to the copied URL.
```
$ export BOUNDARY_ADDR=<actual-boundary-address>
```
HCP Boundary is now set up.

Deploy Vault

(Persona: operations)

Vault is an identity-based secrets and encryption management system. Vault can generate secrets on-demand for some systems, such as AWS, and Kubernetes.

Select the appropriate tab to deploy an HCP Vault Dedicated cluster or deploy a Vault in dev mode.

Launch the HCP Portal and login.
From the Overview page, click Vault in the left navigation menu.
From the Vault overview click Create cluster under the Start from scratch section.
Select your preferred cloud provider.
Click the Vault tier pull down menu and select Development.
Click the Cluster size pull down menu and select Extra Small.
Under the Network section, accept or edit the Network ID, Region selection, and CIDR block for the HVN.
Leave Cluster accessibility set to Public.
Security consideration
All new development tier Vault Dedicated clusters are configured with public access enabled by default. This means clients can connect from anywhere. For production tiers (starter, standard, and plus) private access will be enabled by default. This means you can only connect from a transit gateway or peered VPC (AWS) or VNet (Azure).
Under the Basics section, accept or edit the default Cluster ID (vault-cluster).
Under Templates, select Start from scratch.
Click Create cluster.
Wait for the cluster to initialize before proceeding.
Under Quick actions, click Public Cluster URL.
Return to the terminal you started Kubernetes in and set the VAULT_ADDR environment variable to the copied URL.
```
$ export VAULT_ADDR=<public_cluster_URL>
```
Return to the Overview page and click Generate token.
Within a few moments a new token will be generated.
Copy the Admin Token.
Return to the terminal you started Kubernetes in and set the VAULT_TOKEN environment variable to the copied token.
```
$ export VAULT_TOKEN=<admin_token>
```
Set the VAULT_NAMESPACE environment variable to admin.
```
$ export VAULT_NAMESPACE=admin
```

Open a new terminal window, and start a proxy to expose the Kubernetes API.

$ kubectl proxy --disable-filter=trueRequest filter disabled, your proxy is vulnerable to XSRF attacks, please be cautiousStarting to serve on 127.0.0.1:8001

Leave this terminal open with the proxy running.

Open a new terminal window, and start ngrok and create a tunnel to the proxy listening on port 8001.

Warning

ngrok is used to expose the Kubernetes API to Vault Dedicated. Using --scheme=http exposes the API without encryption to avoid TLS certificate errors.

For production workloads, use a private peering or transit gateway connection with trusted certificates.

$ ngrok http --scheme=http 127.0.0.1:8001

Example output:

ngrok                                                                                                                                                              (Ctrl+C to quit)Session Status                onlineAccount                       username (Plan: Free)Update                        update available (version 3.0.5, Ctrl-U to update)Version                       3.1.1Region                        United States (us)Latency                       32.791235msWeb Interface                 http://127.0.0.1:4040Forwarding                    http://d12b-34-567-89-10.ngrok.io -> 127.0.0.1:8001Connections                   ttl     opn     rt1     rt5     p50     p90                              0       0       0.00    0.00    0.00    0.00

Leave this terminal open with ngrok running.

Copy the ngrok forwarding address.
Return to the terminal you started Kubernetes in and set an environment variable for the ngrok forwarding address.
```
$ export KUBE_API_URL=<actual-address-from-ngrok>
```
Vault Dedicated is now set up.

Learn the current terminal window open.

In a new terminal, start Vault in dev mode.

$ vault server -dev -dev-root-token-id=root==> Vault server configuration:            Api Address: http://127.0.0.1:8200                     Cgo: disabled         Cluster Address: https://127.0.0.1:8201            Go Version: go1.19.1            Listener 1: tcp (addr: "127.0.0.1:8200", cluster address: "127.0.0.1:8201", max_request_duration: "1m30s", max_request_size: "33554432", tls: "disabled")               Log Level: info                  Mlock: supported: false, enabled: false         Recovery Mode: false               Storage: inmem               Version: Vault v1.13.0-dev1, built 2022-09-26T14:39:49Z            Version Sha: 2a7c3f2f76e6fd6a7f8622ea68d82bcf9dcf9686==> Vault server started!

Return to the terminal you started Kubernetes in and set the VAULT_ADDR environment variable.
```
$ export VAULT_ADDR='http://127.0.0.1:8200'
```
Set the VAULT_TOKEN environment variable.
```
$ export VAULT_TOKEN=root
```

Open a new terminal window, and start a proxy to expose the Kubernetes API.

$ kubectl proxy --disable-filter=trueRequest filter disabled, your proxy is vulnerable to XSRF attacks, please be cautiousStarting to serve on 127.0.0.1:8001

Leave this terminal open with the proxy running.

Return to the terminal you started Kubernetes in and set an environment variable for the Kubernetes API URL.
```
$ export KUBE_API_URL=http://127.0.0.1:8001
```

Vault is now set up.

Deploy an HCP Boundary worker

An HCP worker deployed on the same network as Vault is required for integrating private Vault clusters with HCP Boundary. To learn more about setting up self-managed workers, refer to the Self-Managed Worker Registration with HCP Boundary tutorial.

Download the Boundary Enterprise binary

Download the Boundary Enterprise binary to the ~/boundary-kubernetes/ directory.

You can manually download the latest binary for your operating system by navigating to the Boundary releases page. The example below demonstrates downloading the binary using the command line.

Note

The binary version should match the version of the HCP control plane. Check the version of the control plane in the HCP Boundary portal, and download the appropriate version using wget. The example below installs the 0.13.2 version of the Boundary Enterprise binary.

Below is an example of downloading and unzipping the Boundary Enterprise binary on Ubuntu, MacOS, and Windows.

The following command downloads the Boundary Enterprise binary and unzips it to the current directory.

$ wget -q https://releases.hashicorp.com/boundary/0.13.2+ent/boundary_0.13.2+ent_linux_amd64.zip ;\sudo apt-get update && sudo apt-get install unzip ;\unzip *.zip

Once downloaded, verify the version of the boundary binary.

$ ./boundary versionVersion information:  Build Date:          2023-08-04T12:29:52Z  Git Revision:        b1f75f5c731c843f5c987feae310d86e635806c7  Metadata:            ent  Version Number:      0.13.2+ent

The following command downloads the Boundary Enterprise binary and unzips it to the current directory.

$ wget -q https://releases.hashicorp.com/boundary/0.13.2+ent/boundary_0.13.2+ent_darwin_amd64.zip ;\/usr/bin/unzip *.zip

Once downloaded, verify the version of the boundary binary.

$ ./boundary versionVersion information:  Build Date:          2023-08-04T12:29:52Z  Git Revision:        b1f75f5c731c843f5c987feae310d86e635806c7  Metadata:            ent  Version Number:      0.13.2+ent

The following command downloads the Boundary Enterprise binary and unzips it to the current directory.

$ Invoke-WebRequest -OutFile worker.zip https://releases.hashicorp.com/boundary/0.13.2+ent/boundary_0.13.2+ent_windows_amd64.zip ;Expand-Archive -Path worker.zip -DestinationPath .

Once downloaded, verify the version of the boundary binary.

$ .\boundary.exe versionVersion information:  Build Date:          2023-06-07T16:41:10Z  Git Revision:        fb4ed58459d555d480e70ddc20d2639c26ad0f8f  Metadata:            ent  Version Number:      0.13.2+ent

Ensure the Version Number matches the version of the HCP Boundary control plane. They should match in order to get the latest HCP Boundary features.

Write the worker config

Next, create a new file named hcp-worker.hcl in the ~/boundary-kubernetes/ directory.

$ touch ~/boundary-kubernetes/hcp-worker.hcl

Open the file with a text editor, such as Vi.

Paste the following configuration into the worker config file:

disable_mlock = truehcp_boundary_cluster_id = "<cluster-id>"listener "tcp" {  address = "127.0.0.1:9202"  purpose = "proxy"}worker {  auth_storage_path = "/home/myusername/boundary/hcp-worker"  tags {    type = ["worker", "dev"]  }}

Update the cluster id in the hcp-worker.hcl file:

The <cluster-id> on line 3 can be determined from the UUID in the HCP Boundary Cluster URL. For example, if your Cluster URL is:

https://c3a7a20a-f663-40f3-a8e3-1b2f69b36254.boundary.hashicorp.cloud, then the cluster id is c3a7a20a-f663-40f3-a8e3-1b2f69b36254

The auth_storage_path should match the full path to the ~/boundary-kubernetes/hcp-worker directory, such as /home/myusername/boundary/hcp-worker.

disable_mlock = truehcp_boundary_cluster_id = "<cluster-id>"listener "tcp" {  address = "127.0.0.1:9202"  purpose = "proxy"}worker {  auth_storage_path = "/Users/myusername/boundary-kubernetes/hcp-worker"  tags {    type = ["worker", "dev"]  }}

Update the cluster id in the hcp-worker.hcl file:

The <cluster-id> on line 3 can be determined from the UUID in the HCP Boundary Cluster URL. For example, if your Cluster URL is:

https://c3a7a20a-f663-40f3-a8e3-1b2f69b36254.boundary.hashicorp.cloud, then the cluster id is c3a7a20a-f663-40f3-a8e3-1b2f69b36254

The auth_storage_path should match the full path to the ~/boundary-kubernetes/hcp-worker directory, such as /Users/myusername/boundary-kubernetes/hcp-worker.

disable_mlock = truehcp_boundary_cluster_id = "<cluster-id>"listener "tcp" {  address = "127.0.0.1:9202"  purpose = "proxy"}worker {  auth_storage_path = "C:/Users/myusername/boundary-kubernetes/hcp-worker"  tags {    type = ["worker", "dev"]  }}

Update the cluster id in the hcp-worker.hcl file:

The <cluster-id> on line 3 can be determined from the UUID in the HCP Boundary Cluster URL. For example, if your Cluster URL is:

https://c3a7a20a-f663-40f3-a8e3-1b2f69b36254.boundary.hashicorp.cloud, then the cluster id is c3a7a20a-f663-40f3-a8e3-1b2f69b36254

The auth_storage_path should match the full path to the ~/boundary-kubernetes/hcp-worker directory, such as C:/Users/myusername/boundary-kubernetes/hcp-worker.

Save this file.

Start the worker

With the worker config defined, start the worker server. Provide the full path to the worker config file (such as /home/myusername/boundary/hcp-worker.hcl).

The worker will start and begin attempting to connect to the upstream Controller.

The worker also outputs its authorization request as the Worker Auth Registration Request token. This will also be saved to a file, auth_request_token, defined by the auth_storage_path in the worker config.

Note the Worker Auth Registration Request: value. This value can also be located in the ~/boundary-kubernetes/hcp-worker/auth_request_token directory. Copy this value.

Register the worker with HCP

HCP workers can be registered using the Boundary CLI or Admin Console Web UI.

Authenticate to HCP Boundary as the admin user.

Log in to the HCP portal.
From the HCP Portal's Boundary page, click Open Admin UI - a new page will open.
Enter the admin username and password you created when you deployed the new instance and click Authenticate.

Once logged in, navigate to the Workers page.

Notice that only HCP workers are listed.

Click New.

HCP Workers

Scroll down to the bottom of the New Worker page and paste the Worker Auth Registration Request key you copied earlier.

Click Register Worker.

HCP Workers

Click Done and notice the new worker on the Workers page.

HCP Workers

Ensure that the BOUNDARY_AUTH_METHOD_ID and BOUNDARY_ADDR variables are set.

$ export BOUNDARY_AUTH_METHOD_ID=copied-value-from-boundary-ui; export BOUNDARY_ADDR=copied-value-from-hcp-portal

Log into the CLI, providing the admin login name and admin password when prompted.

$ boundary authenticatePlease enter the login name (it will be hidden):Please enter the password (it will be hidden):Authentication information:  Account ID:      acctpw_VOeNSFX8pQ  Auth Method ID:  ampw_ZbB6UXpW3B  Expiration Time: Mon, 13 Feb 2023 12:35:32 MST  User ID:         u_ogz79sV4sTThe token was successfully stored in the chosen keyring and is not displayed here.

Next, export the Worker Auth Request Token value as an environment variable.

$ export WORKER_TOKEN=<Worker Auth Registration Request Value>

The token is used to issue a create worker request that will authorize the worker to Boundary and make it available. Currently worker creation is only supported for workers with an authorization token.

Now, create the HCP worker:
