Issue with concurrent layer metadata extraction #62
Description
Describe your question here
There is a race condition when caching two layer concurrently. I was found this bug by concurrently running two
ext, err := NewExtractor(server, img, true)
_, err = ext.SaveToC()
in an errgroup.Group
The image we are caching
"starlight/mariadb@sha256:9c0c61b8c8c7e406f48ab2c9fb73181e2f0e07ec327f6a8409f7b64c8fc0a0d6",
"starlight/mariadb:10.11.4"
What kind of hardward you have?
