In order to send requests to the Amazon API via REST, you have to sign them to make identifiable. Your environment must have cURL and OpenSSL command line tools installed. Your AWS Identity and Access Management (IAM) user/ IAM instance profile of your Amazon EC2 instance must have IAM policy that allows executing “ssm:getparameters”. In the end I will attach the script that performs the whole process. Below I will briefly go through all the steps and highlight the details you should know. Moreover, there are no posts on how it works with AWS EC2 i nstance profile credentials (the ones we inherit from the Amazon EC2 instance) and nothing on how to do all of that for AWS SSM API. The issue (and the reason why I am writing this post) was, that there are not many tutorials in the Internet on how to do that with cURL. The only solution left was to communicate with Amazon API via Representational state transfer (REST) with cURL. Installing AWS CLI would mean bringing in Python with all its dependencies - not an option. Base image used was busybox and it was making the situation even more complicated. The container was quite tiny and had no AWS CLI on it. For me it was the moment when I had to extract AWS Systems Manager (AWS SSM) Parameters from inside a Docker container running in Amazon Elastic Container Service (Amazon ECS) on Amazon Elastic Compute Cloud (Amazon EC2) Instance. C:\curl\curl-7.59.0-win64-mingw\bin\curl.Sometimes your project may need to communicate with AWS Application Programming Interface (Amazon API) without any access to AWS Command Line Interface (AWS CLI) or Software Development Kits (AWS SDK). Use the following to send a curl to a Slack hook. In the Edit environment variable dialog box, click New and add the path to the curl.exefile.Select the “Path” variable in System Variables, and click Edit.In the Advanced tab, click the Environment Variables button on the lower right side.Note: In Windows 7, right-click Computer and select Properties. In the Start menu, right-click This PC and select More > Properties.Rename this file to: curl-ca-bundle.crtĬredits to CharlesNadeau on the following guide.Typically, this is located in c:\curl\bin Extract this to where curl.exe is located.Make sure to download the one from: Viktor Szakats.
