A basic setup for HashiCorp Vault to handle application secrets in Golang. We are going to use Docker to run the HashiCorp Vault server. After that, we will manually set it up so our Golang application connects to it.
In this example we are going to use Docker to run the HashiCorp Vault server. After that, we will manually set it up so our Golang application connects to it. This is my personal suggestion.

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
Run Go Service in Docker. Why use Docker at all? By using Docker, you can create a neat deploy system for yourself. You can easily change the port for Go web server without changing the Go code itself. You can run multiple different databases at the same time.
Recently while working on an API that interfaced with a database, I mistakenly updated our ORM package to the latest version. The code…
