Docker Deployment

New repo here: https://github.com/hashicorp-education/learn-boundary-target-aware-workers

This directory contains an example deployment of Boundary using docker-compose and Terraform. The lab environment is meant to accompany the Hashicorp Learn Boundary target-aware workers tutorial.

In this example, Boundary is deployed using the hashicorp/boundary Dockerhub image. The Boundary service ports are forwarded to the host machine to mimic being in a "public" network. Boundary is provisioned via Terraform to include targets for popular databases:

• postgres
• redis
• mysql

All of these targets are on containers that are not port forwarded to the host machine in order to mimic them residing in a private network. Boundary is configured to reach these targets via Docker DNS (domain names defined by their service name in docker-compose). Clients can reach these targets via Boundary, and an example is given below using the redis-cli.

Getting Started

There is a helper script called run in this directory. You can use this script to deploy, login, and cleanup.

Start the docker-compose deployment:

./run all

To login your Boundary CLI:

./run login

To stop all containers and start from scratch:

./run cleanup

Login to the UI:

• Open browser to localhost:9200
• Login Name: user1
• Password: password
• Auth method ID: find this in the UI when selecting the auth method or from TF output

$ boundary authenticate password -login-name user1 -password password -auth-method-id <get_from_console_or_tf>

Authentication information:
  Account ID:      apw_gAE1rrpnG2
  Auth Method ID:  ampw_Qrwp0l7UH4
  Expiration Time: Fri, 06 Nov 2020 07:17:01 PST
  Token:           at_NXiLK0izep_s14YkrMC6A4MajKyPekeqTTyqoFSg3cytC4cP8sssBRe5R8cXoerLkG7vmRYAY5q1Ksfew3JcxWSevNosoKarbkWABuBWPWZyQeUM1iEoFcz6uXLEyn1uVSKek7g9omERHrFs

Connect to Private Redis

Once the deployment is live, you can connect to the containers (assuming their clients are installed on your host system). For example, we'll use redis-cli to ping the Redis container via Boundary:

$ boundary connect -exec redis-cli -target-id ttcp_Mgvxjg8pjP -- -p {{boundary.port}} ping
PONG

Explore the other containers such as Postgres and Mysql (default passwords are set via env vars in the docker-compose.yml file).

$ boundary connect postgres -target-name postgres -target-scope-name databases -username postgres -- -l
Password for user postgres:

           |          |          |            |            | postgres=CTc/postgres
 test1     | postgres | UTF8     | en_US.utf8 | en_US.utf8 |
(4 rows)

$ boundary connect postgres -target-name postgres -target-scope-name databases -username postgres -- -l
psql: error: server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.

The mysql target is purposefully misconfigured with worker filters and corrected in the tutorial.
