This comment has been minimized.Terraform: Advantages and Disadvantages. If you are already familiar with Terraform, then you may have encountered a recent change to the way remote state is handled, starting with Terraform v0.
First off… if you are unfamiliar with what remote state is check out this page. Why not just keep the Terraform state in the same git repo I keep the Terraform code in? So, what happened to terraform remote anyway? With the release of Terraform v. Unless you are religious about reading the release notes, you may have missed an important change in v. More specifically, they provide a link to a guide for migrating from the legacy remote state config to the new backend system.
The steps are pretty straightforward and the new approach is much improved over the prior method for managing remote state. So, while the change is good, a deprecation warning in v. At least it is still backwards compatible with the legacy remote state files up to version 0. Prior to v. You could provide arguments like: backend and backend-config to configure things like the S3 region, bucket, and key where you wanted to store your remote state. Most often, this looked like a shell script in the root directory of your Terraform directory that you ran whenever you wanted to initialize or configure your backend for that project.
This was a bit clunky but functional. The introduction of Terraform v. Now we can replicate that same remote state backend configuration with a Backend Resource in a Terraform configuration like so:. Prior to upgrading to Terraform v.

The days when IT admins would install servers manually are slowly but surely fading away.
However, as in any situation that removes manual processes, something else must take its place, and in this circumstance it is Infrastructure as code. With the use of a structured file, a piece of code you were now able to control anything in your infrastructure; networks, compute resources, storage, automation, DNS, databases, security, scaling, everything.
And, although most of the functionality has moved over to Heat native resources, the tools are still beneficial for everyday use. As the use of cloud technologies and infrastructure grew, the need for solutions that are not solely dependent on a single vendor became a necessity. Cloud environments fail, and with all your eggs in a single basket, IT becomes vulnerable.
IT admins started to look for a way to deploy their workloads across clouds and different providers to minimize exposure to risk. The missing piece in this scenario, was a single tool that would allow the end user be it an IT admin or a developer creating an application to manage multiple environments with a standard set of tools.
Welcome to Terraform. Terraform can manage existing and popular service providers as well as custom in-house solutions, OpenStack, being one of them. Terraform is self-sufficient and executable, which makes it extremely simple to install, and it works on almost any platform.
Terraform has a number of modules that will allow you manage your OpenStack infrastructure. It does support some but not all of the components of OpenStack, namely:. The one obvious component that is not supported is Heat — the orchestration engine — for an obvious reason, Terraform itself is an orchestration tool, and duplication is never a good thing. In the following example, we will deploy 2 OpenStack instances, install a web server on each of them and configure each of the servers with a default index.
Terraform stores the configuration in files with a. First up we will define the variables. Here we have a file that will store all the information you need to interact with your OpenStack infrastructure.
Next, we have the provider definitions, the values will be populated from our variable definitions above. Here we have defined a how many instances are to be deployed and given each of them a name accordingly. To test the configuration — we run the following command. This will go through the configuration that you have provided and do a dry run — and will print out what the outcome of your provisioned state will be.
An example of such outcome is below:. The last line details that two resources will be created. Since this is first time that they are going to be created, nothing will be changed, or destroyed. After deployment you can see that there are two instances, each with Apache running and their default page populated. Of course cleaning up afterwards is just running another command:. Is Terraform a full replacement for Heat? However, Terraform is a powerful provisioning tool and it has the option to interact with multiple cloud providers and other solutions thus providing a complete infrastructure solution.
Finally, a simple way to build and scale infrastructure with AWS-compatible services on-prem. How can we help?Learn the Learn how Terraform fits into the. The OpenStack provider is used to interact with the many resources supported by OpenStack. The provider needs to be configured with the proper credentials before it can be used. See the OpenStack openstacksdk documentation for more information about clouds.
It should be possible to omit the region in single-region OpenStack environments, but this behavior may vary depending on the OpenStack environment being used. You can specify either a path to the file or the contents of the certificate. You can specify either a path to the file or the contents of the key.
If not set, public endpoints is used. Setting an override requires you to specify the full and complete endpoint URL. This might also invalidate any region you have set, too. Please see below for more details.
Please use this at your own risk. Note that this will only work when used with the OpenStack Object Storage resources. This is useful, when the token TTL is low or the overall Terraform provider execution time expected to be greater than the initial token TTL. There might be a situation in which you want or need to override an API endpoint rather than use the endpoint which was returned to you in the service catalog.
You must make sure you specify the full and complete endpoint URL for this to work. This provider supports:. Please use this feature at your own risk.
If you are unsure about needing to override an endpoint, you most likely do not need to override one.
This provider has the ability to log all HTTP requests and responses between Terraform and the OpenStack cloud which is useful for troubleshooting and debugging. If you submit these logs with a bug report, please ensure any sensitive information has been scrubbed first! This provider aims to support "vanilla" OpenStack. This means that we do all testing and development using the official upstream OpenStack code.
If your OpenStack environment has patches or modifications, we do our best to accommodate these modifications, but we can't guarantee this.
We try to support all releases of OpenStack when we can. If your OpenStack cloud is running an older release, we still should be able to support it.
4 Ways to Manage Your OpenStack Secrets with Terraform and git
Using this OpenStack provider with Rackspace is not supported and not guaranteed to work; however, users have reported success with the following notes in mind:. Interacting with instances has been seen to work. Interacting with all other resources is either untested or known to not work.Supporting Materials. In this tutorial we will briefly cover what Terraform is and how you can leverage it for your needs.
This will not make you an expert on Terraform but will give you the tools you need in order to maintain your cloud infrastructure as code. This will be a very practical training with emphasis on looking at examples from modules and becoming self sufficient. This tutorial uses the OpenStack provider for Terraform.
Other Cloud providers are available, but their invocation will be different from that which is described here.
This is known as infrastructure as code. Knowing that your infrastructure is exactly what you expect it to be can simplify your operations significantly. You can have confidence that if anything changes, any images crash or are accidentally deleted, that you can immediately re-build your infrastructure.
Use Galaxy. We simply updated the credentials for connecting to the cloud, and ran Terraform. It recognised that none of our existing resources were there and recreated all of them. This made life incredibly easy for us, we knew that our infrastructure would be exactly correct relative to what it looked like in the previous cloud. Terraform supports many providersallowing you to easily manage resources no matter where they are located. Primarily this consists of resources like virtual machines and DNS records.
If you have VMs you are managing, whether for individual projects or for large scale infrastructure like Use Galaxy. Support for certain databases and other software is available, but whether or not this is a good idea depends heavily on your workflow. We launch VMs with terraform and then provision them with ansible. To then have a second step where we re-connect and provision the database with terraform was an awkward workflowso we mostly let Ansible manage these resources.
Some groups use Ansible or Bash scripts in order to launch VMs. This can be a better workflow for certain cases. Launching VMs that manage themselves or are automatically scaled by some exte rna l process is not a good fit. We will start small, by managing a single VM in our cloud account. Make sure you have your OpenStack credentials available. Terraform reads all files with the extension.
Resources can be in a single file, or organised across several different files.
Deploying a compute cluster in OpenStack via Terraform
We had the best experience by separating out logical groups of resources:. This specifies the configuration for the OpenStack plugin. You can either specify the configuration in the plugin, or it will automatically load the values from the normal OpenStack environment variable names. This is the minimum to get started with Terraform, defining which providers we will use and any parameters for them. We have two options now:. We recommend the first option, as often Terraform plans are made publicly available in order to collaborate on them, and this prevents accidentally committing your credentials to the git repository where.
Instead you can simply reference the key by name later. We will point out this location. Find the public key you will use for connecting to the your new VM. If you can find the private key file possibly a cloud.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
