Hello Mahsa,
Regarding the error you're seeing:
> DEBUG Ignoring error connecting to compute001: Invalid key -- <class
> 'paramiko.ssh_exception.SSHException'>
My first guess would be that you pointed ElastiCluster to some SSH key
file that it cannot read.
Check your configuration file; you should have some lines like the
following ones:
[login/google]
image_user=riccardo.murri
# ...
user_key_private=~/.ssh/elasticluster
user_key_public=~/.ssh/elasticluster.pub
The lines influencing the SSH logins are the two `user_key_*` ones.
Things to check:
1. *Both files must exist* on the machine where you run `elasticluster
-vvvv start ...`
2. The file name is immaterial (could be `id_rsa` or `id_ed25519` or
`google_cloud_sdk`) but, because of a bug, ElastiCluster can only use
SSH keys of type RSA. To find out what type is the SSH key you're
using, run this command (replace `~/.ssh/elasticluster-dev` with the
path pointed to by `user_key_private` in your config file):
$ ssh-keygen -l -f ~/.ssh/elasticluster-dev
4096 SHA256:9r/pBW5nB2mnFrGIFxuxs8HW4ZVWDUbS/AzMeU3tjRM riccardo.murri@dev (RSA)
If instead of "(RSA)" you get a different code, you will need to
generate an RSA key and use that instead:
1. Create a new RSA key for use with elasticluster:
ssh-keygen -t rsa -b 4096 -o -a 100 -f ~/.ssh/elasticluster
2. Replace the `user_key_*` lines with the following:
user_key_private=~/.ssh/elasticluster
user_key_public=~/.ssh/elasticluster.pub
If after making these changes you are still running into issues,
please post or send to me via email your configuration file (WARNING:
remove all private data like passwords and access keys!!)
Hope this helps,
Riccardo
