The incorrect system time meant that signatures for requests were being computed incorrectly. Setting the system time to the correct value solved the problem -- if you ensure that your docker container sets the system time for example by using NTP , your problem might go away like mine did.
I had the same issue here with a docker running on windows. The problem was, that the Hyper-V time is stopped, once your pc is going in stand-by mode. This was causing problems, because the timestamp from my request and from the AWS - bucket was different. It seems, that this is a issue from docker:.

As you may have noticed, we have used sync or cp in the above commands. Just for your knowledge, the difference between the sync and cp is that the sync option syncs your bucket with the local folder whereas the cp command copies the objects you specified to the local folder. For our purpose to download files from s3 we can use either one of sync or cp.

For creating a connection we can pass the AWSCredentials object as a parameter. Next, create the TransferManager object using s3client, TransferManager provides asynchronous management for uploads and downloads between your application. Using the s3client. Using Iteratoriterate the al objects. Finally, close the connection of TransferManager object otherwise it's running continuously. Using the shutdownNow ; the method to close the connection.

Often when debugging applications, it is useful to copy files into or out of our Docker containers. In this tutorial, we'll look at some different ways we can copy files to and from Docker containers. The quickest way to copy files to and from a Docker container is to use the docker cp command.
This command closely mimics the Unix cp command and has the following syntax:. Before we look at some examples of this command, let's assume we have the following Docker containers running:. We can also copy an entire directory instead of single files. The docker cp command does have some limitations. First, we cannot use it to copy between two containers. It can only be used to copy files between the host system and a single container.
Second, while it does have the same syntax as the Unix cp command, it does not support the same flags. In fact, it only supports two:. Another way to copy files to and from Docker containers is to use a volume mount. No i am afraid history does pass back those args.. I guess the question is if they have access to that could they get the secrets anyway?
If it is a huge issue look at suggestion 2 i said or maybe something like this could help - docs. I wanted to build upon Ankita Dhandha answer. In the case of Docker you are probably looking to use ECS. IAM Roles are absolutely the way to go. An example would be having access to S3 to download ecs. Task Roles are used for a running container. An example would be a live web app that is moving files in and out of S3.
Task Execution Roles are for deploying the task. An example would be downloading the ECR image and deploying it to ECS, downloading an environment file from S3 and exporting it to the Docker container.
Not everything behaves like this. But many do so you have to research it for your situation.
