Docker Build Example: How to Go From Slow To Fast Docker Builds

In this post, we will see a docker build example of a node js API application starting from slow and ending up in a ~10x faster build. I have already talked about the reasons to use docker for development environment. I have also mentioned how docker changed the way we software engineers work and multi-stage docker build in past posts. For this one let’s focus on the docker build example with faster build in mind.

Information before jumping in

1. Familiarity with Docker and the docker build process is required
2. All examples are based on Docker version 19.03.13, build 4484c46d9d on a Mac
3. The Currency API app is used for this docker build example

Docker Explained: Docker Architecture | Docker Registries

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

In this video lesson you will learn:

• What is Docker Host
• What is Docker Engine
• Learn about Docker Architecture
• Learn about Docker client and Docker Daemon
• Docker Hub and Registries
• Simple demo to understand using images from registries

#docker #docker hub #docker host #docker engine #docker architecture #api

What's new in the go 1.15

Go announced Go 1.15 version on 11 Aug 2020. Highlighted updates and features include Substantial improvements to the Go linker, Improved allocation for small objects at high core counts, X.509 CommonName deprecation, GOPROXY supports skipping proxies that return errors, New embedded tzdata package, Several Core Library improvements and more.

As Go promise for maintaining backward compatibility. After upgrading to the latest Go 1.15 version, almost all existing Golang applications or programs continue to compile and run as older Golang version.

Docker: Define, Build and Run

In this blog post, I’m going to share my experience with using docker to create a container for my application.

What is Docker?

Docker is an open platform for developing, shipping, and running applications. It packages up an application or service with all of its dependencies into a standardized unit a.k.a “Image”

Why use Docker?

There are a lot of individual machines and VM running with different OSes and it’s hard to stay up to date with the operating systems as well as their dependencies. This is where Docker shines and solves that problem. Docker streamlines the development lifecycle by providing standardized environments using local containers.
