Provide latest version in S3 download URL

[rungitringit]

Hello,

I maintain a SOE for a fleet of Linux desktops which use the ecr-credential-helper.
Currently I must source this from an S3 URL which varies based on the latest stable release version. For example it is currently: https://amazon-ecr-credential-helper-releases.s3.us-east-2.amazonaws.com/0.10.0/linux-amd64/docker-credential-ecr-login

Could the S3 link for this project please provide a fixed link to the latest stable release?

I mean something like:
https://amazon-ecr-credential-helper-releases.s3.us-east-2.amazonaws.com/latest/linux-amd64/docker-credential-ecr-login

Without this I must regularly check to see if the version has changed and update our codebase regularly.
I'm happy to wear the risk that the latest stable version hasn't been tested in our environment.

Thank you!

I explored this option a bit, in general i think its not good practice to use a immutable tag.
Is it possible for you to automate it:

LATEST_VERSION=$(curl -s "https://api.github.com/repos/awslabs/amazon-ecr-credential-helper/releases/latest" | jq -r '.tag_name')
VERSION=${LATEST_VERSION#v}
https://amazon-ecr-credential-helper-releases.s3.us-east-2.amazonaws.com/{VERSION}/linux-amd64/docker-credential-ecr-login

and then you can use it to download it without changing your script. I would suggest it to be part of automated script for the update so that you control the version and also know when a new version is out.

Thank you for responding @Shubhranshu153

You are assuming about how I install and update this across a fleet of systems.
Unfortunately it's not as simple as a one-off curl command. I need to bake the URL in to a git repository which runs the automation tool we use. It would add considerable complexity if I had to automate the process of regularly checking for a new version before running the automation (it's a long story).

Can i get some info on the setup to understand the use case, as in is it possible that we are not able to run the curl command in the automation infrastructure?

Hello again,
I'm afraid that I cannot go in to detail here. If you have access to the AWS Support ticket associated with this, could you please reach out to me there? Our TAM has linked the ticket with this Github issue.

Could you please explain why you think it is not good practice to have a download for the latest in S3?
I do not want you to change your github flow, nor to take away version-specific paths in S3, only that you also always provide a static download path in S3 please.
