I’ve spent the whole day on this so any help would be greatly appreciated.
I followed the install guidelines for docker for azure (https://docs.docker.com/docker-for-azure/) and installed the docker CE stable channel successfully on azure.
Next step is trying to connect to the manager node using following command
ssh -i “E:\temp\DockerKeys\private.ppk” -p 50000 email@example.com
but this always fails with following error.
Unable to negotiate with 51.144.118.xxx port 50000: no matching host key type found. Their offer: ssh-rsa,rsa-sha2-512,rsa-sha2-256
I generated the public/private key pair using putty key generator and entered the public key in the deploy template.
The type of key is SSH2 RSA. I also tried to use SSH1, but this fails on deployment (The value of parameter linuxConfiguration.ssh.publicKeys.keyData is invalid.)
I tried with a shorter SSH2 RSA key of 512 but get the same error.
Steps to reproduce the behavior
Generate public private key using putty key generator and use the public key + other parameters as input for the template.
Find the public ip of the manager node and try to connect using the private key
Thanks in advance for any help.
