Error launching source instance: Your requested instance type (t2.micro) not supported in your requested Availability Zone (us-west-2d).

[ghost]

Getting this error every now and then while I am running my test configurations. The point to note is, I haven't specified us-west-2d availability zone in any of my configurations. And when I get this error, I do a terraform destroy (to destroy created VPC, subnets, etc.), and then run terraform apply again. On the second time, it completes without any errors.

This kind of errors usually happens when the subnet is not specified (or not specified with the correct value).

Could you verify that you specify correct subnet? Please include terraform code if the problem persists.

No I am not, but I am creating the complete tire-2 setup from scratch using terraform configuration and only specifying us-west-2 as the region, and amiID. So I couldn't define the subnet ahead of the run. Does that mean such error could not be suppressed in such use-cases?

You should reference values from VPC as an argument into this module as specified here - https://github.com/terraform-aws-modules/terraform-aws-ec2-instance/blob/master/examples/basic/main.tf#L62

This does seem like a better approach. Thanks.

Hi, I have the same issue. I'm not sure what you mean with "reference values from VPC as an argument".

I used this https://github.com/terraform-aws-modules/terraform-aws-ec2-instance/blob/master/examples/basic to create the ec2 instances.

@jakemonton AWS may enable and disable certain types of instances or other resources (eg, when AZ is down, you can't launch resources there) at their discretion.

"reference values from VPC as an argument" means that to make this working you need to set subnet_id and/or other arguments to valid values.

I hope it helps.

@antonbabenko I was able to make it work. It was the subnet_id value. Thank you!
