Error: importing charts: Error: insecure registry is not valid: invalid host

[ganeshsrvnn]

What happened:

When using eksctl anywhere import images command to import the images and charts to a private registry with self signed CA where the images are pushed successfully, then helm is asked to log in, and fails due to host is invalid
"Error: importing charts: Error: insecure registry xxx.local/eks-a is not valid: invalid host "xxx.local/eks-a"

What you expected to happen:

Using the eksctl anywhere import images, All the images and helm charts must be pushed to private registry successfully without error.

How to reproduce it:

• Configure a registry with a private CA
• Install self signed CA .crt in /etc/docker/certs.d/xxx.local/ca.crt
• Follow documentation airgapped procedure as far as step 5.
• The error will occur after the docker images are pushed to the registry.

Anything else we need to know?:

• My registry use default port 443 and the ca.cert is placed in /etc/docker/certs.d/
• The registry is password authenticated and hence they are passed in environment variables REGISTRY_USERNAME and REGISTRY_PASSWORD
• The registry URL is set in env variable REGISTRY_MIRROR_URL
• I attach the logs with -v 9 verbosity

Environment:

Admin OS: Red Hat Enterprise Linux 9.4 (Plow)
eksctl version: 0.210.0
eksctl-anywhere version: v0.23.0

After a lot of debugging, I found the problem is with private registry configuration which is blocking insecure helm login to the registry. I rectified it by correcting the private registry repo path to xxx.local rather than xxx.local/repository/eks-a.
Hence closing the case.

Hello,
I am reopening this issue after the helm login command failed during eksa import images command and successful login from admin machine.
This might be an issue in helm login from eksa cli tool launched through docker. I tried out the helm login to the registry from the admin vm which was successful whereas the eksa anywhere import images command failed.
Please let me know if there`s a workaround or fix that can be applied to overcome this problem.
