Failing to pull image from private repo #4178
Description
If I have a yml file as follows:
kernel:
image: xyz.dkr.ecr.us-east-1.amazonaws.com/my-kernel-image:whatever
cmdline: whatever
In 1.7.1, linuxkit build correctly pulls this image from AWS using my Docker credentials.
After 1.8.0, linuxkit build fails with the following error:
Extract kernel image: xyz.dkr.ecr.us-east-1.amazonaws.com/my-kernel-image:whatever
Error: failed to extract kernel image and tarball: could not pull image xyz.dkr.ecr.us-east-1.amazonaws.com/my-kernel-image:whatever: error getting manifest for image 9
