title: How I can inject artifact from AWS S3 inside Docker image?
body: <p>I need to prepare Docker image with embedded Jar file to push it into ECR. Jar file is storing in S3 bucket. How I can inject jar inside image <strong>without explicit storing AWS access keys into image</strong>? 
  Maybe I can use AWS CLI or exist other way? 
  Also it is not recommended to add public access to my s3 bucket and set access keys via env variable during execute <code>docker run</code>.</p>
