Issue type --Docker swarm ca rotate with new certs,keys failing with SHA1 -RSA error
Client: Docker Engine - Community
API version: 1.40 (minimum version 1.12)
Steps to reproduce
Whenever try to rotate cert in docker swarm it fails with sha1 error.
docker swarm ca --rotate --ca-cert customcrt.pem --ca-key customkey.pem
"Error response from daemon: rpc error: code = InvalidArgument desc = unsupported signature algorithm: SHA1-RSA"
Is it that docker only supports sha256 root ca .Any recommendations how to solve this??
We are unable to generate a cross-signed certificate for root rotation as per
