Boundary



Boundary is an identity-aware proxy that provides a simple, secure way to access hosts and critical systems on your network.



With Boundary you can:



* Integrate with your IdP of choice using OpenID Connect, enabling users to securely sign-in to their Boundary environment

* Provide just-in-time network access to network resources, wherever they reside 

* Manage session credentials via a native static credential store, or dynamically generate unique per-session credentials by integrating with HashiCorp Vault

* Automate discovery of new endpoints

* Manage privileged sessions using Boundary’s session controls

* Standardize your team's access workflow with a consistent experience for any type of infrastructure across any provider



Boundary is designed to be straightforward to understand, highly scalable, and 

resilient. It can run in clouds, on-prem, secure enclaves and more, and does not require

an agent to be installed on every end host, making it suitable for access to managed/cloud services and container-based workflows in addition to traditional host systems and services.

For more information, refer to "[What is Boundary?](https://developer.hashicorp.com/boundary/docs/overview/what-is-boundary)" on the Boundary website.



## Getting Started



Boundary consists of two server components: 



* **Controller**, which serves the API and coordinate session requests

* **Workers**, which perform session handling



A real-world Boundary installation will likely consist of one or more

controllers paired with one or more workers. A single Boundary binary can act

in either, or both, of these two modes.



Additionally, Boundary provides a Desktop client and CLI for end-users to request and establish 

authorized sessions to resources across a network.

Boundary does _not_ require software to be installed on your hosts and services.



## Requirements



Boundary has two external dependencies: 

- A SQL database

- At least one KMS



### SQL database

The database contains Boundary's configuration and session information. The 

controller nodes must be able to access the database. 



Values that are secrets (e.g credentials) are encrypted in the database. Currently, PostgreSQL is supported as a database and has been tested with Postgres 12 and above.



Boundary uses only common extensions and both hosted and self-managed instances are supported. In most instances, all that you need is a database endpoint and the appropriate credentials.



### KMS 

Boundary uses KMS keys for various purposes, such as protecting secrets, authenticating workers, recovering data, encrypting values in Boundary’s configuration, and more. Boundary uses key derivation extensively to avoid key sprawl of these high-value keys.



You can use [any cloud KMS or Vault's Transit Secrets Engine to satisfy the KMS requirement](https://developer.hashicorp.com/boundary/docs/configuration/kms). 



## Trying out Boundary



Running Boundary in a more permanent context requires a few more steps, such

as writing some simple configuration files to tell the nodes how to reach their

database and KMS. The steps below, along with the extra information needed

for permanent installations, are detailed in our [Installation Guide](https://developer.hashicorp.com/boundary/docs/install-boundary/install).



> ⚠️  Do _not_ use the `main` branch except for dev or test cases. Boundary 0.10 introduced release branches which should be safe to track, however, migrations in `main` may be renumbered if needed. The Boundary team will not be able to provide assistance if running `main` over the long term results in migration breakages or other bugs.



### Download and Run from Release Page



Download the latest release of the server binary and appropriate desktop

client(s) from our [downloads page](https://developer.hashicorp.com/boundary/downloads)



## Quickstart with Boundary Dev



Boundary has a `dev` mode that you can use for testing. In `dev` mode, you can start both a

controller and worker with a single command, and they have the

following properties:



* The controller starts a PostgreSQL Docker container to use as storage.

  This container will be shut down and removed, if possible, when the

  controller is shut down gracefully.

* The controller uses an internal KMS with ephemeral keys



### Building from Source

If you meet the following local requirements, you can quickly get up and running with Boundary:

- Go v1.21 or greater

- Docker

- Either the [Boundary UI dependencies](https://github.com/hashicorp/boundary-ui#prerequisites)

  for locally building the ui assets

  or [gh cli](https://cli.github.com) for downloading pre-built ui assets.



Simply run:



  ```make install```



This will build Boundary. (The first time this is run it will fetch and compile

UI assets; which will take a few extra minutes.) Once complete, run Boundary in

`dev` mode:



  ```$GOPATH/bin/boundary dev```



Please note that development may require other tools; to install the set of

tools at the versions used by the Boundary team, run:



  ```make tools```



Without doing so, you may encounter errors while running `make install`. It is important

to also note that using `make tools` will install various tools used for Boundary

development to the normal Go binary directory; this may overwrite or take precedence

over tools that might already be installed on the system.



### Start Boundary



Start the server binary with:



  ```boundary dev```



This will start a Controller service listening on `http://127.0.0.1:9200` for

incoming API requests and a Worker service listening on `http://127.0.0.1:9202`

for incoming session requests. It will also create various default resources and

display various useful pieces of information, such as a login name and password

that can be used to authenticate.



### Configuring Resources



For a simple test of Boundary in `dev` mode you don't generally need to

configure any resources at all! But it's useful to understand what `dev` mode

did for you so you can then take further steps. By default, `dev` mode will

create:



* The `global` Scope for initial authentication, containing a Password-type

  Auth Method, along with an Account for login.

* An organization Scope under `global`, and a project Scope inside the

  organization.

* A Host Catalog with a default Host Set, which itself contains a Host with the

  address of the local machine (`127.0.0.1`)

* A Target mapping the Host Set to a set of connection parameters, with a

  default port of `22` (e.g. SSH)



You can go into Boundary's web UI or use its API to change these

default values, for instance if you want to connect to a different host or need

to modify the port on which to connect.



### Making the Connection



Next, let's actually make a connection to your local SSH daemon via Boundary:



1. Authenticate to Boundary; using default `dev` values, this would be `boundary

   authenticate password -auth-method-id ampw_1234567890 -login-name admin

   -password password`. (Note that if you do not include the `password` flag you

   will be prompted for it.)

2. Run `boundary connect ssh -target-id ttcp_1234567890`. If you want to adjust

   the username, pass `-username ` to the command.



Check out the possibilities for target configuration to test out limiting (or increasing) the

number of connections per session or setting a maximum time limit; try canceling

an active session from the sessions page or via `boundary sessions`, make your

own commands with `boundary connect -exec`, and so on.



### Going Further



This example is a simple way to get started but omits several key steps that

could be taken in a production context:



* Using a firewall or other means to restrict the set of hosts allowed to

  connect to a local service to only Boundary Worker nodes, thereby making

  Boundary the _only_ means of ingress to a host

* Using the [Boundary Terraform provider](https://registry.terraform.io/providers/hashicorp/boundary/latest) to easily integrate Boundary with your

  existing code-based infrastructure

* Pointing a BI tool (PowerBI, Tableau, etc.) at Boundary's data warehouse to

  generate insights and look for anomalies with respect to session access
