Google Cloud- Unable SSH into instance via cloud shell.

Unable to ssh into instance via Google Cloud. This may be because the ssh-keys metadata is throwing out wacky errors in gcp-instance.tf file.

commenting out a line to see if that fixes it

That didn't work. Did find this new error though

Invalid key. Required format: username@example.com or google-ssh {"userName":"username@example.com","expireOn":""}

Alright, it looks like when you press the "add ssh key" button on the VM instance, google attempts to add keys BUT this kills the unbuntu user and then you lose access to your instance. Looking into how to use OS login instead.

I know we chatted about this on discord - but do you have the error you mentioned in the first comment? Was it from terraform or in the gcp web console?

[wibbene]

It is caused by something that terraform is configuring. Because of the first issue, the second issue is happening.

[wibbene]

I am still running it down in my free time because otherwise the script works great!

To recap, the malformed SSH key is fixed in 6242d2e

google cloud ssh keys work with or without a key name. e.g.: ssh-rsa some_key_data my_key_name or ssh-rsa some_key_data) BUT if the key name is omitted the google cloud web console complains.

I've added logic in terraform to add ubuntu as the key name if the user does not supply a key name in gcp.tfvars, which should clear that error up.

To re-iterate - a missing key name would not have prevented SSH access. Going to close this as solved.
