Subject: [PATCH] docker: Support check manifest and layer's DiffID info when
|
|
pulling image failed
|
|
|
|
reason: When pulling image, the downloaded layer and the layer recorded in
|
|
the config could be different and which will cause the
|
|
"errRootFSMismatch" error. What we should do is to trace more info on that and
|
|
log them for better analysing after error occured.
