Unable to sign docker image with ioxclient

[junyi]

While using ioxclient to sign the docker image, I always got the errer below

The private/public key and ca certificate were generated by openssl in pem format.

ioxclient.exe docker pkg -k privkey.pem -c CA.pem testapp:2.0 ./dev

Without using parameter -c and -k I was able to repackage the image as IOX package, but everytime I want to sign, no success.

Does anybody know the reason, something wrong with the keys?

Hello @junyi,

There is also an IOx Mailer within Cisco called the iox-support(mailer list):

iox-support@cisco.com

Hope this helps!
