In this chapter, we built and deployed our Vault Go application using Docker to Digital Ocean's cloud.

After installing the Docker tools, we saw how easy it was to package up our Go application into a Docker image and push it to Docker Hub. We created our Digital Ocean droplet using the helpful Docker app that they provide and controlled it via a web-based console. Once inside, we were able to pull our Docker image from the Docker Hub and run it inside our droplet.

Using the public IP of the droplet, we were then able to remotely access the Vault service's JSON/HTTP endpoint to hash and validate passwords.
