Connecting to RabbitMQ server from Golang with self-signing SSL certificates. We are going to create a Golang client to connect to our RabbitMQ server through TLS. For that, we will have to create self-signed SSL certificates and share those between the Golang application and the RabbitMQ server.
In this example we are going to create a Golang client to connect to our RabbitMQ server through TLS. For that, we will have to create self-signed SSL certificates and share those between the Golang application and the RabbitMQ server.
Create the Dockerfile below in your system and run
docker build --no-cache . command. This will output the content of all the required certificate files in terminal. Manually create the files and keep them somewhere for now. For more details, visit Using tls-gen's Basic Profile link.

We are going to create a Docker container that will act as an executable to process some image files. We are going to use Go (Golang) to write an image processing program. For this, we would be working with Docker VOLUME, ENTRYPOINT, and other Dockerfile instructions.
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…
