Terraform Configuration Files

In attachment. I do not attach all files but the main. Main files of the module and main files of the configuration that create the VM.

Debug Output

Crash Output

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform planned the following actions, but then encountered a problem:

  # module.VM["VM-PPROD-FRONT-PRE-AZa-NGINX-01"].outscale_nic.NIC-VM will be updated in-place
  ~ resource "outscale_nic" "NIC-VM" {
        id                     = "eni-dcc8df38"

Expected Behavior

After the migration and make a plan, no error.

Actual Behavior

After the migration and make a plan on a VM with public IP, error.

Steps to Reproduce

I make the migration procedure in "https://github.com/outscale/terraform-provider-outscale" on the chapter "Migration to v1"

Additional Context

Before to migrate on 1.0.0, if needed, we connected public IP through the tag osc.fcu.eip.auto-attach. All plans has even if no public IP. SInce the migration, if the VM has no public IP, no problem. But if the VM has a public IP connected, there is the error in the Crash Output.

Hi @sylvain987,
Thanks for reaching us,
You need to make some sed in your terraform configuration/state.
For your issue:

sed -i '/"link_public_ip": {/, /},/d' terraform.tfstate
sed -i '/"link_nic": {/, /},/d' terraform.tfstate

Have a look on terraform-provider-outscale Readme for migration

[sylvain987]

Hello,

This is the sed commands that I applied on all configurations and check on your migration guide :

terraform fmt
sed -i '/"block_device_mappings_created": \[/, /\],/d' terraform.tfstate
sed -i 's/outscale_volumes_link/outscale_volume_link/g' terraform.tfstate
sed -i '/"link_public_ip": {/, /},/d' terraform.tfstate
sed -i '/"link_nic": {/, /},/d' terraform.tfstate
sed -i '/"flexible_gpu_id": "/, /",/d' terraform.tfstate
sed -i '/"accepter_net": {/, /},/d' terraform.tfstate
sed -i '/"source_net": {/, /},/d' terraform.tfstate
sed -i '/"state": {/, /},/d' terraform.tfstate 
sed -i 's/outscale_volumes_link/outscale_volume_link/g' *.tf
sed -i 's/flexible_gpu_id /flexible_gpu_ids /g' *.tf
sed -i '/flexible_gpu_ids /s/= /= \[/' *.tf
sed -i '/outscale_flexible_gpu\./s/$/ \]/' *.tf
terraform fmt

On all configurations, Terraform create a parameter call link_public_ip with a empty content on NIC resource. If I apply again the 2 sed commands and make a plan, I have the same result :

[svc_terraform@frparadm73 nginx]$ sed -i '/"link_public_ip": {/, /},/d' terraform.tfstate
[svc_terraform@frparadm73 nginx]$ sed -i '/"link_nic": {/, /},/d' terraform.tfstate
[svc_terraform@frparadm73 nginx]$ terraform plan -out=main.tfplan

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  ~ update in-place

Terraform planned the following actions, but then encountered a problem:

  # module.VM["VM-PPROD-FRONT-PRE-AZa-NGINX-01"].outscale_nic.NIC-VM will be updated in-place
  ~ resource "outscale_nic" "NIC-VM" {
        id                     = "eni-dcc8df38"

Hi @sylvain987,

After sed commands can you please do terraform refresh before terraform plan -out=main.tfplan
like :

[svc_terraform@frparadm73 nginx]$ sed -i '/"link_public_ip": {/, /},/d' terraform.tfstate
[svc_terraform@frparadm73 nginx]$ sed -i '/"link_nic": {/, /},/d' terraform.tfstate
[svc_terraform@frparadm73 nginx]$ terraform refresh
[svc_terraform@frparadm73 nginx]$ terraform plan -out=main.tfplan

you will still get

# module.VM["VM-PPROD-FRONT-PRE-AZa-NGINX-01"].outscale_nic.NIC-VM will be updated in-place
  ~ resource "outscale_nic" "NIC-VM" {
        id                     = "eni-dcc8df38"
      + link_public_ip         = (known after apply)
        # (14 unchanged attributes hidden)

        # (1 unchanged block hidden)
    }

  # module.VM["VM-PPROD-FRONT-PRE-AZb-NGINX-02"].outscale_nic.NIC-VM will be updated in-place
  ~ resource "outscale_nic" "NIC-VM" {
        id                     = "eni-9e3e7a9e"
      + link_public_ip         = (known after apply)
        # (14 unchanged attributes hidden)

        # (1 unchanged block hidden)
    }

But it will be OK after terraform apply without change your resources

In the state of terraform-plugin under v1.0.0-rc.1 we have

....
  link_nic   = {

        "vm_id"                 = null                                                                                                                                                                                                                                        
    }

            "public_ip_account_id" = null
            "public_ip_id"         = null
   }
.....

In v1.0.0-rc.1 We have

....
       link_nic          = []
       link_public_ip    = []
....

Hi,

I make a terraform refresh before terraform plan but I have the same error :

By default, the state is on Gitlab. So my migration procedure is a little bit different :

terraform init -plugin-dir=/opt/terraform/plugins -upgrade
terraform state pull > terraform.tfstate
terraform fmt
sed -i '/"block_device_mappings_created": \[/, /\],/d' terraform.tfstate
sed -i 's/outscale_volumes_link/outscale_volume_link/g' terraform.tfstate
sed -i '/"link_public_ip": {/, /},/d' terraform.tfstate
sed -i '/"link_nic": {/, /},/d' terraform.tfstate
sed -i '/"flexible_gpu_id": "/, /",/d' terraform.tfstate
sed -i '/"accepter_net": {/, /},/d' terraform.tfstate
sed -i '/"source_net": {/, /},/d' terraform.tfstate

sed -i 's/outscale_volumes_link/outscale_volume_link/g' *.tf
sed -i 's/flexible_gpu_id /flexible_gpu_ids /g' *.tf
sed -i '/flexible_gpu_ids /s/= /= \[/' *.tf
sed -i '/outscale_flexible_gpu\./s/$/ \]/' *.tf
terraform fmt
old_serial=$(grep serial terraform.tfstate | awk '{print $2}' | sed 's/.$//')
new_serial=$(echo $(($(grep serial terraform.tfstate | awk '{print $2}' | sed 's/.$//')+1)))
sed -i "s/  \"serial\": ${old_serial},/  \"serial\": ${new_serial},/g" terraform.tfstate
terraform state push terraform.tfstate
terraform refresh
terraform plan -out=main.tfplan

I can restore a old version of the state before the sed commands.

Regards.

@sylvain987 With your migration procedure, is the refresh/plan working correctly now ?

[sylvain987]

Hi,

No. I have the same error.

Regards.

[outscale-rce]

Ok, thank you. We are not able to reproduce the issue. Do you have the possibility to test your configuration without using GitLab, just to be sure it is not the cause?

[sylvain987]

Hello,

I tested without Gitlab (on a local state file). I have the same error (to make the test without Gitlab, I create a POC VM) :

Planning failed. Terraform encountered an error while generating this plan.

╷

│

Do you want to check the state file without the secrets of course to continue the debug ?

Regards.

[outscale-rce]

Yes, state file will be useful. Thank you for your patience.

[sylvain987]

This is the state : terraform.tfstate.txt

I add again the error after the plan :

Hi @sylvain987,

We found the error: private_ips.0.link_public_ip : ' ' : source data must be an array or slice, got map
And we made a PR to fix it.

Thanks a lot.

Best Regards,

[sylvain987]

Hello,
Perfect. Do you know when the new version will be release ?
Regards.

[outscale-rce]

Hello @sylvain987 ,
A new version with some bug fixes should be available by the end of this week.

[sylvain987]

Nice, thank you.
