Google云实例上的Terraform ssh错误？

我一直在通过与ssh的Terraform Provisioner连接问题进行斗争。 到目前为止，我已经尝试过以前的工作：

provisioner "remote-exec" { inline = [ "echo ${google_compute_instance.testing-elastic-1.network_interface.0.access_config.0.assigned_nat_ip}"] connection { type = "ssh" user = "root" private_key = "${file("~/.ssh/google_compute_engine")}" timeout = "45s" } } 

但我不断收到以下错误。

 Error applying plan: 1 error(s) occurred: * ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain 

我也尝试在terminal上用ssh直接login到IP。

 ssh -i ~/.ssh/google_compute_engine.pub 122.122.122.122 

这工作得很好。 所以我也在configuration中试过这个，或者我认为会在configuration中模仿这个。

• Google App Engine灵活环境中可用的内存
• 在Google云端DNS中创buildMXlogging
• 在MySQL中使用云存储连接MySQL
• joomla在谷歌appengine
• Google Cloud SQL授权自动比例实例组

 provisioner "remote-exec" { inline = [ "echo ${google_compute_instance.testing-elastic-1.network_interface.0.access_config.0.assigned_nat_ip}"] connection { type = "ssh" user = "" private_key = "${file("~/.ssh/google_compute_engine")}" timeout = "45s" } } 

有另一个错误。

应用计划时出错：

发生1个错误：

• ssh：handshake failed：ssh：无法进行身份validation，尝试的方法[none publickey]，没有支持的方法

所以然后我尝试了这个。

 provisioner "remote-exec" { inline = [ "echo ${google_compute_instance.testing-elastic-1.network_interface.0.access_config.0.assigned_nat_ip}"] connection { type = "ssh" private_key = "${file("~/.ssh/google_compute_engine")}" timeout = "45s" } } 

最后，似乎没有任何改变。 我刚刚回来这个错误信息。

 Error applying plan: 1 error(s) occurred: * ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain 

我真的不知道还有什么我应该有或需要的SSHauthentication工作。

 resource "google_compute_instance" "my-host" { // ... connection { type = "ssh" agent = false user = "${var.gce_ssh_user}" port = "${var.gce_ssh_port}" timeout = "5m" private_key = "${file("${var.gce_ssh_private_key_file}")}" } // ... }
