Overview

This README aims to allow the setup of a development local environment as quick as possible. It uses predefined configuration files that are maintained with the source code as well as Docker to run ancillary services (such as databases).

Dependencies

• Go 1.12+

Debugging

This guide can be used to run all of the Ziti applications via command line or in the debugger of an IDE.

Get Started

Checkout & Build

1. Checkout the ziti repository from github.com/openziti/ziti
   • git clone https://github.com/openziti/ziti.git
2. Change into the ziti dirrectory
   • cd ziti
3. Build
   • go build ./ziti-controller
   • go build ./ziti-router
   • go build ./ziti/cmd/ziti

Starting the Controller

If you wish to start the controller with the Ziti Fabric and Ziti Edge enabled:

ziti-controller run etc/ctrl.with.edge.yml

If you wish to start the Ziti Fabric standalone:

ziti-controller run etc/ctrl.yml

Please note that if you start the controller without the Ziti Edge enabled, the Ziti SDK, and edge router functionality will not be usable. The controller can be started and stopped both ways without issue.

Starting Routers

The Ziti Fabric requires at least one router (fabric router or edge router). There are four predefined configuration files for running routers in etc/ named 001.yml to 004.yml.

Each configuration file refers to certificate and private keys kept in etc/ca/intermediate/certs and etc/ca/intermediate/private/. The steps for starting the router is to first register the router then start it.

Register:

ziti-fabric create router etc/ca/intermediate/certs/XXX-client.cert.pem

Where XXX is replaced with 001 through 004.

Run:

ziti-router run etc/XXX.yml

Where XXX is replaced with 001 through 004.

Starting Router As An Edge Router

Edge routers are routers that have the Edge functionality enabled and allow Ziti SDK enabled application to connect to Ziti. Starting an edge eouter requires that the controller be running with the Edge functionality enabled. This requires the use of the ctrl.with.edge.yml configuration to run the controller (see example above).

To start an edge router the Edge REST API will be used to prime the enrollment process and the ziti-router enroll command will be used to finalize the process. The enrollment command will handle adding the fabric and edge router entries necessary. Using the ziti-fabric create router command should not and can not be run.

There is only one example configuration file for an edge router: etc/edge.router.yml. Additional configuration files can be created by copying and altering the file. Specifically the identity section needs to point to unique file locations that do not collide with other identity file and the listening ports need to not be in use.

Authenticate w/ the Ziti Edge API

Please note that this is not a complete API reference and all of these request have analogous commands in the Ziti CLI via the ziti binary.

POST /authenticate?method=password
{
    "username": "admin",
    "password": "admin"
}

Authentication will return a session token that should be supplied either as a cookie (also returned) or a HTTP header called zt-session. All subsequent requests will either need to set the HTTP set zt-session or provide the cookie in every request.

Create An Edge Router

POST /edge-routers
{
  "name": "My Edge Router",
}

Retrieve the Edge Router Enrollment Token

GET /edge-routers/<id>

...where id is provided in the response to creating an edge router. It can be re-retrieved by listing the existing edge routers via GET /edge-routers. The response from retrieving a edge router should contain an enrollment JWT in the enrollmentJwt field. Retain the enrollment JWT in a text file named enrollment.jwt.

Enroll the Edge Router

ziti-router enroll --jwt <path to enrollment.jwt> etc/edge.router.yml

...where path to enrollment.jwt is the enrollment JWT for the edge router.

Start Ziti Edge Router

ziti-router run etc/edge.router.yml

Further Exploration

At this point the controller should be running with some number of routers running. It is now possible to explore the Ziti Fabric capabilities via the ziti-fabric executable.

If the controller was started with the Edge functionality enabled the Ziti Edge API can be explored. A POSTMAN collection can be found in github.com/openziti/edge/controller/postman and the Ziti SDK can be found in netfoundry/sdk-golang. Additionally the ziti-enroller and ziti-tunnel command in this repository contain reference implementations.
