using terraform to create aws NFS file share - terraform-provider-aws

any idea how i can use terraform to create nfs file share?
I need to create the s3 bucket
then
create nfs file share on existing storage gateway which I need to use the bucket name I created in step 1
any idea how to do in terraform?

You will need 3 terraform resources :
aws_s3_bucket
resource "aws_s3_bucket" "my_bucket" {
bucket = "my-nfs-bucket"
acl = "private"
tags = {
Author = "me"
Environment = "dev"
}
}
aws_storagegateway_gateway
resource "aws_storagegateway_gateway" "my-storagegateway" {
gateway_ip_address = "1.2.3.4"
gateway_name = "storage-gateway"
gateway_timezone = "GMT"
gateway_type = "FILE_S3"
}
aws_storagegateway_nfs_file_share
resource "aws_storagegateway_nfs_file_share" "my_bucket" {
client_list = ["0.0.0.0/0"]
gateway_arn = aws_storagegateway_gateway.my-storagegateway.arn
location_arn = aws_s3_bucket.my_bucket.arn
role_arn = aws_iam_role.my-role.arn
}
You will also need in the role_arn key-value the ARN of the AWS Identity and Access Management (IAM) role that a file gateway assumes when it accesses the underlying storage.

Terraform error configuring AWS provider backend issue

i've had this issue in terraform with backend configuration. I am getting this error when running Terraform plan.

Can you use your AWS CLI to connect to your AWS account? like listing your AWS s3 buckets? based on the error I think you didn't configure your AWS by doing aws configure on your CLI. which will require you to have an access key id and secret for the setup.
You must configure AWS' credentials in the Terraform Cloud. In the Terraform Cloud platform, go to Settings -> Variable Sets -> Create Variable Set, put some "name", check "Apply to all workspaces in this organization" and click on buttom "Add Variable". Select "Environment variable" option, and inform the key=AWS_ACCESS_KEY_ID and value="Access key ID". The "Acces key ID" is the ID from AWS credential(IAM). Check the "sensitive" checkbox and click on buttom "Add Variable". So, retry this process to add a new Environment variable with the key/value pair AWS_SECRET_ACCESS_KEY/Secret access key of AWS credential. Finally, click on buttom "Create variable set". Retry the terraform plan command. See more in https://developer.hashicorp.com/terraform/tutorials/aws-get-started/aws-remote#set-workspace-variables

GCP GKE cannot access Redis Memorystore

I have Kubernetes cluster in GCP (GKE) that cannot connecto to Memorystore(Redis).
All of the resources related to the project are in a dedicated network.
network module:
resource "google_compute_network" "my_project" {
name = "my_project"
auto_create_subnetworks = true
}
output "my_project_network_self_link" {
value = google_compute_network.my_project_network.self_link
}
I use the network in the GKE cluster (network = "${var.network_link}"):
resource "google_container_cluster" "my_project" {
name = "my_project-cluster"
location = "us-central1"
node_locations = ["us-central1-a", "us-central1-b"]
network = "${var.network_link}"
# We can't create a cluster with no node pool defined, but we want to only use
# separately managed node pools. So we create the smallest possible default
# node pool and immediately delete it.
remove_default_node_pool = true
initial_node_count = 1
master_auth {
username = ""
password = ""
client_certificate_config {
issue_client_certificate = false
}
}
}
Node pools omitted.
and I set the network as authorized_network in the memorystore configuration:
resource "google_redis_instance" "cache" {
name = "my_project-redis"
tier = "STANDARD_HA"
memory_size_gb = 1
authorized_network = "${var.network_link}"
# location_id = "us-central1-a"
redis_version = "REDIS_4_0"
display_name = "my_project Redis cache"
}
variable "network_link" {
description = "The link of the network instance is in"
type = string
}
I guess that the problem is related to the network, because previously using the default network this was working fine.
Currently the GKE nodes are in us-central1-a and us-central1-b(specified in the TF script) and memory store is in us-central1-c. So the cluster and the Redis are in the same VPC but in different sub-networks. Could this be the problem?
I had to add the following section to the cluster module in terraform:
ip_allocation_policy {
cluster_ipv4_cidr_block = ""
services_ipv4_cidr_block = ""
}
This seems to enable the VPC-native (alias IP) property of the cluster.

update exisitng terraform compute instance when added new "components"

I am new with terraform, but I have created an openstack compute instance like this:
provider "openstack" {
auth_url = "https://my-auth/v2.0/"
domain_name = "default"
alias = "alias"
user_name = "username"
tenant_name = "tenantname"
password = "pwd"
region = "region"
}
# Import SSH key pair into openstack project
resource "openstack_compute_keypair_v2" "keypair" {
provider = "myprovider"
name = "keypair"
public_key = "${file("~/.ssh/id_rsa.pub")}"
}
# Create a new virtual machine
resource "openstack_compute_instance_v2" "compute_instance" {
name = "compute_instance" # Instance Name
provider = "myprovider" # Instance distr
image_name = "Centos 7" # Image name
flavor_name = "b2-7" # Machine type name
key_pair = "${openstack_compute_keypair_v2.keypair.name}"
network {
name = "Ext-Net"
}
}
For maintainability and flexibility reasons I would like to add some "components" in the same instance, it could be anything, but here I have tried with a provisionner file and remote execution.
Indeed, when I add this arguments in my compute instance, I noticed that my compute instance will not be updated. For example:
provider "openstack" {
auth_url = "https://my-auth/v2.0/"
domain_name = "default"
alias = "alias"
user_name = "username"
tenant_name = "tenantname"
password = "pwd"
region = "region"
}
resource "openstack_compute_keypair_v2" "keypair" {
provider = "myprovider"
name = "keypair"
public_key = "${file("~/.ssh/id_rsa.pub")}"
}
resource "openstack_compute_instance_v2" "compute_instance" {
name = "compute_instance" # Instance Name
provider = "myprovider" # Instance distr
image_name = "Centos 7" # Image name
flavor_name = "b2-7" # Machine type name
key_pair = "${openstack_compute_keypair_v2.keypair.name}"
network {
name = "Ext-Net"
}
# Add a provisionner file on the ressource
provisioner "file" {
source = "foo_scripts/bar-setup.sh"
destination = "/tmp/bar-setup.sh"
connection {
type = "ssh"
user = "user"
private_key = "${file("~/.ssh/id_rsa")}"
}
}
# execute server setup file
provisioner "remote-exec" {
inline = [
"chmod +x /tmp/bar-setup.sh",
"sudo bash /tmp/bar-setup.sh",
]
connection {
type = "ssh"
user = "centos"
private_key = "${file("~/.ssh/id_rsa")}"
}
}
Indeed, by adding the provionner file on the ressource, when I run the command terraform plan or terraform apply, nothing change on my instance. I have infos messages notify me that:
Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
What it's the right way to apply my changes to my compute instance.
Following Terraform documentation:
Provisioners are used to execute scripts on a local or remote machine as part of resource creation or destruction.
If you want the provisionners to run again, you should destroy (terraform destroy) and create (terraform apply) the resource again.
There's no way that Terraform can check the state of a local or a remote execution, it's not like there's an API call that can tell you what happen on your custom code - bar-setup.sh.
That would be like magic, or actual Magic.
Terraforms' for managing the infrastructure, the config of the instance, and not really for the content on the instance. Immutable content and recreating is the true path here. Making a completely new instance. However if it's your Hammer there are ways.
If you taint the resource that you want to update, then when terraform is run again next time the resource will be re-executed. But heed what I said about Hammers.
Alternatively you could leverage your CM tool of choice to manage the content of your instance - Chef/Ansible or create the images (i.e. immutable) used by Openstack via a tool like packer and update those. I'd do the latter.

Terraform Provisioner "local-exec" not working as expected | VPC Peering Connection Accept issue

I'm unable to get the auto accept peering done through the work around mentioned in the link (Why am I getting a permissions error when attempting to auto_accept vpc peering in Terraform?"] via provisioner option
See below Terraform code of mine. Can some one help me out?
provider "aws" {
region = "us-east-1"
profile = "default"
}
provider "aws" {
region = "us-east-1"
profile = "peer"
alias = "peer"
}
data "aws_caller_identity" "peer" {
provider = "aws.peer"
}
resource "aws_vpc_peering_connection" "service-peer" {
vpc_id = "vpc-123a56789bc"
peer_vpc_id = "vpc-YYYYYY"
peer_owner_id = "012345678901"
peer_region = "us-east-1"
accepter {
allow_remote_vpc_dns_resolution = true
}
requester {
allow_remote_vpc_dns_resolution = true
}
provisioner "local-exec" {
command = "aws ec2 accept-vpc-peering-connection --vpc-peering-connection-id=${aws_vpc_peering_connection.service-peer.id} --region=us-east-1 --profile=peer"
}
}
Output I'm getting:
Error: Error applying plan:
1 error(s) occurred:
* aws_vpc_peering_connection.servicehub-peer: 1 error(s) occurred:
* aws_vpc_peering_connection.servicehub-peer: Unable to modify peering options. The VPC Peering Connection "pcx-08ebd316c82acacd9" is not active. Please set `auto_accept` attribute to `true`, or activate VPC Peering Connection manually.
Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure
Where as I'm able to run the aws cli command successfully via linux shell, outside the terraform template. Let me know if I'm missing out something in the terraform script.
Try with moving out your "local-exec" and add depends on link with your VPC peering.
resource "null_resource" "peering-provision" {
depends_on = ["aws_vpc_peering_connection.service-peer"]
provisioner "local-exec" {
command = "aws ec2 accept-vpc-peering-connection --vpc-peering-connection-id=${aws_vpc_peering_connection.service-peer.id} --region=us-east-1 --profile=peer"
}
}
As said Koe it's may be better to use auto_accept option.

Postfix Folders

When I retrieve messages (with imap) the folder /home/user/mail is created while my config files (postfix and dovecot) redirects to /home/user/Maildir folder, and Maildir folder contains emails I want to get with imap !
I made a symbolic link between these folders and now with android I can retrieve messages stored in strange folders. With ThunderBird I can not explore folders. I see that dovecot creates an .imap folder where messages are finally stored, but not like expected.
Does somebody knows the mistake I did ?
Best Regards
It was due to a bad dovecot config !
Lines added to /etc/dovecot/dovecot.conf :
ssl = yes
auth_mechanisms = plain login
mail_location = maildir:~/Maildir
passdb {
args = dovecot
driver = pam
}
protocols = imap
service auth {
unix_listener /var/spool/postfix/private/auth {
group = postfix
mode = 0660
user = postfix
}
}
ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem
ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key
userdb {
driver = passwd
}
