AWS ECR: Could not set registry endpoint credentials ... failed timeout after 10s

[bcbrockway]

Describe the bug

We have the Image Updater running on EKS clusters using IRSA to link them to an IAM role that grants it permissions to our ECR registry. In addition, we have an auth script configured to run an awscli command to grab a new token every 11 hours:

# configmap/argocd-image-updater-config
# ...
data:
  registries.conf: |
    registries:
    - api_url: https://000000000000.dkr.ecr.us-east-2.amazonaws.com
      credentials: ext:/scripts/ecr-login-us-east-2.sh
      credsexpire: 11h
      name: ECR
      prefix: 000000000000.dkr.ecr.us-east-2.amazonaws.com

# configmap/argocd-image-updater-authscripts
# ...
data:
  ecr-login-us-east-2.sh: |
    #!/bin/sh
    aws ecr --region 'us-east-2' get-authorization-token --cli-read-timeout 5 --cli-connect-timeout 5 --output text --query 'authorizationData[].authorizationToken' | base64 -d

This usually works on startup, and sometimes after credsexpire, but it also often fails with:

Could not set registry endpoint credentials: error executing /scripts/ecr-login-us-east-2.sh: /scripts/ecr-login-us-east-2.sh failed timeout after 10s

Sometimes this can take hours of retries to rectify and sometimes nothing short of killing the pod and starting a new one will fix it.

It's also weird that it seems to run this script once for each app in its update cycle (see logs below) rather than just running it once seeing as we've configured at the registry level.

To Reproduce
Set up as above. Unfortunately, this is intermittent.

Expected behavior
The script runs correctly (once) and stores the new token for all apps to use.

Additional context
N/A

Version

Setting --max-concurrency to 1 works for me, although I don't know exactly how this fixes the problem 😅

Some of our ArgoCD instances have a lot of apps so this would slow us down quite a bit :(
