While running the clair-container-scan script for local images sometimes it fails with "No image Scanned" message about clair-container-scan

[usr42]

I can reproduce the issue and will investigate.

Thanks for the information!

I got the same error when i tried to scan alpine:edge today

[usr42]

clair-container-scan is not pulling images, but only scanning locally available images, yet.
So, if the image your trying to scan is not available, it will result in a No image scanned output.

@mfmcdonagh Can you try to run:

docker pull alpine:edge

before you run

./clair-container-scan.sh alpine:edge

Is the issue then still happening?

@nishanthboovathy Sorry, that I did not respond earlier. I somehow missed your message.
Did the issue for you also happen, when you were scanning a particular image?

[mfmcdonagh]

[gen] mc@onagm ~/tmp $ docker pull docker.io/alpine:edge
edge: Pulling from library/alpine
Digest: sha256:6199d795f07e4520fa0169efd5779dcf399cbfd33c73e15b482fcd21c42e1750
Status: Image is up to date for alpine:edge
[gen] mc@onagm ~/tmp $ ./clair-container-scan.sh alpine:edge
No image scanned.

Sorry but that didn't help

[usr42]

It seems to be an clair issue:
This is the output I get when running manually:

Maybe Clair has to be updated.

[mfmcdonagh]

should i log an issue for it on coreos/clair ?

[usr42]

It still seems to happen with the latest 2.0.7 version of clair. Logging an issue directly on coreos/clair is a good idea.
