We will be using AWS CLI throughout this post for Creating role ( aws iam create-role ) Attaching policy to the role ( aws iam attach-role-policy ) Deploying Lambda function ( aws lambda create-function ) Invoking the lambda function ( aws lambda invoke ) Our lambda function will return a account detail json as below.

This involves below steps Launching an EC2 instance SSH to EC2 Installing Docker on EC2 Starting Docker service Pulling image from docker hub Running the docker image on EC2 Testing the application For this post, I have created docker image of a GO rest api and pushed to my docker hub repository.

Go middleware are like filters which gets executed for performing pre and/or post processing of the request. middleware or the filters implementation is achieved through http handler wrappers. HttpHandler wrappers are the functions which takes http.Handler as input and returns http.Handler as output. Defining Middleware Here we have defined a simple log request middleware, which takes one argument and returns one argument and of the same type http.

We will explore below topics What is gosec? Installing gosec Running security checks for a GO code Analyzing gosec reports SonarCloud Integration with gosec Companies using gosec What is gosec? gosec is a static code analyzer tool for inspecting go application code for security problems.

Let’s read further… Assuming that you have got docker, git and GO installed on your machine so that you can build your GO app locally and then create a docker image. Multi Stage Build We will be creating a multi stage build.

The complete source code is available on my github repo.I have created 3 branches, each branch representing different flavour of writing service. GO api source code Ok, let’s go ahead… GO - WebService GO package net/http does the job for us. It stars the sever and ready to receive request at /hello with http.
