I tried to containerise a GoLang HTTP server

Introduction

Hi this is Akshay Rao currently working in Annotation.Inc. In this blog I tried to host a simple HTTP server written in GoLang.

Let's Start

We will require docker to be installed in PC.
Go to the project and create a Dockerfile.
Now we will have to write commands which can will launch the app when the Image is ran.


FROM golang:1.16-alpine - this will pull the official base image of golang

RUN mkdir /app

ADD . /app

WORKDIR /app

RUN go build project.go or go build project .

CMD [“/app/project”]

In golang first we compile program and obtain a executable file, then we can run this executable file on any OS.

Build the image “docker build -t /name of the image/ .”( docker build -t first-go-project .)
To check the image has been created or not use “docker image ls”
Then run docker run -p 8080:8080 -it /docker image/

Conclusion

Open localhost:8080 u will be able to see the docker image is running.

if u get stuck the with this error
Use the command “go env -w GO111MODULE=off”
Thank you
