Decrease your Dockerfile build time by enabling BuildKit

I am going to advertise a not well-known parameter that can accelerate your docker builds significantly.

It is called BuildKit.

When BuildKit is enabled, it skips all unused stages and builds each line or layer in parallel to accelerate build times, while the traditional build command does all of these serially.

It was an experimental feature of Docker for a long time. But since 18.09 or higher versions, you can enable it either by setting

export DOCKER_BUILDKIT=1

or you can modify your** /etc/docker/daemon.json **to enable it by default as following

{ "features": { "buildkit": true } }

Showcase

Assume that you have a Dockerfile as following.

FROM golang:1.13.5 AS builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -ldflags="-w -s" -o main .
FROM scratch
WORKDIR /app
COPY --from=builder /app/configs/ ./configs/
COPY --from=builder /app/main ./main
EXPOSE 3200
ENTRYPOINT ["/app/main"]

I have built this Dockerfile in both traditional and BuildKit way.

Standard Docker build time

docker build -t go-dockerbuild .  
0.09s user 0.07s system 0% cpu 1:33.46 total

BuildKit build time

DOCKER_BUILDKIT=1 docker build -t go-dockerbuildkit .  
0.28s user 0.22s system 0% cpu 1:00.01 total

It saved me 33 seconds which means %35 decrease in build time. It is just awesome . Especially in the world of microservices and continuous deployment , it is a significant improvement.

To sum up, BuildKit is one of the best practices of Docker now , it is highly recommended and performant.

Playground Games and Turn 10 Studios respectively improved time on Visual Studio 2019

The C++ team at Visual Studio has delivered substantial build and link time improvements throughout Visual Studio 2019. This blog is Part 2 of a series of blogs showcasing real-world results of our efforts. See how the Gears 5 team benefited from iteration build time improvements in Part 1.

How to Install and Configure Chrony

It is essential to keep the correct time on a server. This is especially true when it comes to processing financial transactions or other vital functions which need to be handled in a specific order. Using the Network Time Protocol (or NTP), computers can synchronize their internal clock times with the internet standard reference clocks. In essence, NTP is a hierarchy of servers. The higher the Stratum number of a server, the more accurate the timing is and the lower the Stratum number of a server is, the lower the accuracy and time stability. Stratus are defined by the distance from the initial reference clock.

Python Datetime Tutorial: Manipulate Times, Dates, and Time Spans

Dealing with dates and times in Python can be a hassle. Thankfully, there’s a built-in way of making it easier: the Python datetime module.

datetime helps us identify and process time-related elements like dates, hours, minutes, seconds, days of the week, months, years, etc. It offers various services like managing time zones and daylight savings time. It can work with timestamp data. It can extract the day of the week, day of the month, and other date and time formats from strings.

The Best Way to Build a Chatbot in 2021

A useful tool several businesses implement for answering questions that potential customers may have is a chatbot. Many programming languages give web designers several ways on how to make a chatbot for their websites. They are capable of answering basic questions for visitors and offer innovation for businesses.

With the help of programming languages, it is possible to create a chatbot from the ground up to satisfy someone’s needs.

Plan Out the Chatbot’s Purpose

Before building a chatbot, it is ideal for web designers to determine how it will function on a website. Several chatbot duties center around fulfilling customers’ needs and questions or compiling and optimizing data via transactions.

Some benefits of implementing chatbots include:

  • Generating leads for marketing products and services
  • Improve work capacity when employees cannot answer questions or during non-business hours
  • Reducing errors while providing accurate information to customers or visitors
  • Meeting customer demands through instant communication
  • Alerting customers about their online transactions

Some programmers may choose to design a chatbox to function through predefined answers based on the questions customers may input or function by adapting and learning via human input.
