Invalid Index errors

[ratkosomni]

Is there a way to edit stack variables in order to resolve the 2 errors below?

Error: Invalid index

Hello,

are you using OCI Resource Manager or are you running the module through Terraform ?

In the latter case, can you share your terraform.tfvars ?

[ratkosomni]

Hi, thanks for responding. I'm using OCI Resource Manager. The "Deploy" button didn't work for me due to the url being gone so I downloaded the zip file of the latest release, uploaded it to a new stack in Resource Manager, edited my variables, ran a "Plan" and got the 2 errors.

[cdivita]

The URL used by Deploy to Oracle Cloud was broken, the right URL is:

https://cloud.oracle.com/resourcemanager/stacks/create?region=home&zipUrl=https://github.com/oracle-quickstart/oci-cloud-native-sftp/releases/latest/download/oci-cloud-native-sftp-stack-latest.zip

The README.md has been updated accordingly, would you try again ?

[ratkosomni]

Using the new link was helpful (thank you!), but the build still fails with the exact same 2 error messages as above.

[cdivita]

Are you using existing subnets, right ?

[cdivita]

@ratkosomni the issue was caused by wrong route table attachment when existing subnets are used. Since the subnets are already there, route tables are not created so their attachment should be skipped.

Now is it possible to run terraform plan successfully for both scenarios (non-existing and existing subnets), also using OCI Resource Manager.

[ratkosomni]

Plan is now able to execute successfully, then attempting to run Apply using the successful Plan output fails.
But even with the "failed" response, it did create the compute instance, load balancer, and OS bucket. Looks like fail errors are related to being unable to set up another NAT Gateway (we have 1 already) and something about the user key (it didn't create a user that I can see). Maybe I can use the components that were successfully provisioned and handle these couple of failed items manually somehow? I may have been mistaken in thinking if we had a NAT gateway already that we wouldn't need a second one created, but we don't have an explicit NAT limit set up in our tenancy so I am not sure why it hit a limit that doesn't exist.

[cdivita]

There cannot be more than one NAT Gateway for VCN, the error message is not clear. However, since existing VCN and subnets have been selected this action should not be in the plan: issue #2 has been created to fix it.

For using Object Storage through S3 Compatibility API, a customer secret key is required. The stack handles it using the pre-populated variables using Resource Manager, however the name of the variable that contains the user OCID changed recently: issue #3 has been created to fix it

[ratkosomni]

Thank you for both fixes. Should I destroy the stack and re-run a Plan+Apply?

Yes, please

[ratkosomni]

Plan and Apply both ran successfully, thank you for your help! This was exactly what my org needed to quickly get an sftp server up and running on our cloud tenancy, can say enough how much I appreciate it.

Hey cdvita,

I'm having the same problem.
