Fix issue Apr 10, Feb 4, Fix stack traces. Jun 11, I recently setup a couple of static sites by hand using CloudFront in front of S3 for https.
If you just want to get a static site up quickly you should use something like Netlify instead. These sites are really low volume so the hosting works out as effectively free. I registered devwhoops. I have also made this work for just a subdomain with no redirects but have left that part out to make this post shorter. The source buckets must be publicly available over HTTP rather than private S3 buckets to allow things like redirects to work. Yes, you do need an entire CloudFront distribution to redirect www.
I put the code needed to create all the moving parts into a single Terraform module that has enough input variables to customize the solution per site.
I use Terragrunt to handle re-using this module and configuring it for each specific site. Three S3 buckets are needed, one for the site content, one for logs and one for the redirect.
The main site bucket index and error documents are configurable as different static sites might need to use these in different ways.
The code above names the bucket after the site domain. The public permissions are below. I find that a lot of Terraform code by volume is specifying policies for resources! AWS Certificate Manager can generate and renew the https certificates for free. It needs proof of domain ownership via the ability to write a CNAME record before it will issue the certificate.
I adapted this article to use DNSimple. This is very handy! The certificates must be in the us-east-1 region. I usually work in eu-west-1 so need to use the Terraform alias support to have a provider in the correct regions. There are two names to validate, the www and non-www version of the apex domain. Now the buckets and the validated certificate resources are setup the next step is to create the CloudFront distributions.
The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I'd like them all to share the same subnet group and security group, and for those to be created if they don't already exist.
My initial attempt was to create a module "redshift" defined like:. This works for creating a single cluster, when creating a second clusuter terraform fails to recognize that the security group and subnet group already exist. What's the proper way to handle this? Break the network setup out into its own module, and have the redshift module depend on it? If you want to have a one-to-many relation between your subnet group and your clusters then you should split the networking components in a separate module than the redshift one.
I would never want a database created in the same stack as application servers or resources as those can change over the life of an application, but the database might not. If your case, you are correct that TF will create the resources if they don't exist, but you misunderstood the context.
TF will create them if they don't exist in the state file, not at AWS. If two stacks try to create the same resource with the same names, stack 1 will create them, stack 2 will try but fail because the resource already exists at AWS. I would separate the security groups and subnet groups into their own module, then use a data source to reference them in the Redshift module.

Is it possible to use a shared cache that re-uses already downloaded modules and their versionsso I don't have to download all of the dependencies for each module instantiation? Collectively it is 10GB of cache. I would be nice to have an option to auto remove cache after execution. I just deleted GB of. By default it should have common directory and use symlink as brikis98 said. Having a flag to create local.
I can't imagine supporting and working on infrastructure with clients or more. I would have to either delete local. One is symlinks already mentioned, second one is proxy and replacing source with adhoc localhost cache repo. Kinda nasty hack.

Unfortunately I don't think I will be able to help to sort this issue. Proxy sounds a bit too hacky. Symlinks are more promising, but not without a lot of complexities and gotchas. We're certainly open to PRs that can think through those issues, but for now, periodically clearing the cache as documented here is hopefully a good-enough workaround.
I'm also interested in this problem. In my case, we have throttled speed to the git server and a fresh pull every time gets slow really fast.

The Gruntwork team is constantly updating the Gruntwork Infrastructure as Code Library with the latest best practices, new features, and bug fixes. Instead of spending months fighting with Terraform or Kubernetes updates, better infrastructure is just a version number bump away see the monthly Gruntwork Newsletter. Work with a team of DevOps experts who can help you set up your infrastructure, design highly available and scalable systems, automate your builds and deployments, troubleshoot issues, and avoid gotchas and pitfalls.
An overview of the core concepts you need to understand to use the Gruntwork Infrastructure as Code Library, including a look into how the Infrastructure as Code Library is designed, how the Reference Architecture is designed, how we build production-grade infrastructure, and how to make use of infrastructure as code, Terraform, Terragrunt, Packer, Docker, immutable infrastructure, versioning, automated testing, and more. Each repo is focused on one type of infrastructure: e.
Used to define and manage most of the basic infrastructure, such as servers, databases, load balancers, and networking. Used to build cross-platform CLI applications e. Install scripts : used to install and configure a piece of software.
Example: the install-elasticsearch script can be used to install Elasticsearch on Linux. Run scripts : used to run a piece of software, typically during boot. Example: you can execute the run-elasticsearch script while a server is booting to auto-discover other Elasticsearch nodes and bootstrap an Elasticsearch cluster. Used for more complicated scripts, especially those that need to run on other operating systems e. Used to define and manage Kubernetes applications and resources.
Example: k8s-service is a helm chart that packages your application containers into a best practices deployment for Kubernetes. Why these tools? We wrote a detailed blog post on why we use Terraform ; as for Go, Bash, and Python, we use them because they work just about everywhere, with few or no external dependencies, and they can be integrated with almost any configuration management approach: e.
We use helm because it has a strong community including official support from the Cloud Native Computing Foundation with many vendors officially packaging their applications into a Helm Chart e. Hashicorp uses Helm to package Vault and Consul for Kubernetes. The code in each repo is organized into three primary folders, modules or charts for Helmexamplesand testas described in the following sections.
Each repo in the Gruntwork Infrastructure as Code Library contains a modules or charts folder that contains the main implementation code, broken down into multiple standalone, orthogonal, reusable, highly configurable modules. This allows you to combine and compose the modules in many different permutations to fit your exact needs: e. Each repo in the Gruntwork Infrastructure as Code Library contains an examples folder that shows you how to assemble the modules from the modules folder into different permutations.
This lets you try the modules out in minutes, without having to write a line of code. In other words, this is executable documentation. Each repo in the Gruntwork Infrastructure as Code Library contains a test folder that contains automated tests for the examples in the examples folder.
These are mostly integration tests, which use Terratest under the hood to deploy the examples into real environments e. For example, after every commit to the ELK repo, we spin up a dozen ELK clusters, perform a variety of validation steps e. This is how we build confidence that the code does what we say it does—and that it continues to do it over years of updates.
All of the code in the Gruntwork Infrastructure as Code Library is versioned. Every time we make a change, we put out a new versioned release, and announce it in the monthly Gruntwork Newsletter. That way, you are not accidentally affected by any subsequent changes in the Gruntwork Infrastructure as Code Library until you explicitly choose to pull those changes in.
PATCH e. In traditional semantic versioning, you increment the:. However, much of the Gruntwork Infrastructure as Code Library is built on Terraform, and as Terraform is still not at version 1. PATCH version numbers. With 0. PATCHthe rules are a bit different, where you increment the:.Note that many of the links below go to private repos in the Gruntwork Infrastructure as Code Library and Reference Architecture that are only accessible to customers. Read on for the full details.
As always, if you have any questions or need help, email us at support gruntwork. Motivation : Last month we announced that all our modules had been upgraded to be compatible with Terraform 0. However, we had yet to update the Gruntwork Reference Architecture, which uses all of our modules under the hood, to be compatible with Terraform 0. What to do about it : The Reference Architecture example repos have now been updated to Terraform 0.
Normally we link you to a diff with the changes that are necessary to update the Reference Architecture code. However, since the change set for this update is huge see this PR for an examplewe instead recommend following our upgrade guide, and using the Acme repos as a reference for what it should look like in the end.
Solution: We released the terraform-google-influx module, which is open source on GitHub under the Apache 2. What to do about it: Read the release blog postgive the modules a try and let us know how they work for you! These modules make it much easier to deploy and manage infrastructure on GCP, but wiring all of them together to build your entire tech stack is still a lot of work. Solution: We are building out an end-to-end, production-grade, secure, and developer-friendly Reference Architecture for GCP!
Motivation : Two months ago we announced Terragrunt 0. The introduction of this new config file allowed us to upgrade the underlying syntax to HCL2 which has many language level improvements that makes it easy to extend the configuration with additional features.
This month we leveraged this new configuration syntax to address two problems:. This month, we introduced two new blocks in Terragrunt: locals and dependency. Consider the following terragrunt. Here, the region is a hard coded string "us-east-1" repeated multiple times throughout the config.
When switching to a new region, we have to replace that string in all three places. With localswe can bind the string to a temporary variable:. Now you only need to update the region string in one place and the rest of the config will inherit that!
Consider the following folder structure:. In most cases, you will most likely want to deploy the database deployed with the mysql module into the VPC deployed with the vpc module. Now, you can address this using the new dependency block. This will run terragrunt output on the vpc module and render that as the variable dependency.
