If you aren’t deeply involved in spinning up Cloud Infrastructure or creating Infrastructure as Code (IaC), then perhaps you wouldn’t be aware of a rather monumental change that happened August 10th.
Hashicorp, the dominant player in the market with Terraform, an Open Source IaC framework with several professional and enterprise offerings, announced that as of the next versions of all their products, they would move off open-source by dropping the MPL in favour of a new BUSL, or Business Source License, which is ‘source ajar’ or ‘source available’ like Oracle Java or IBM Red Hat Enterprise.
First, let’s start with the fun part - getting going with OpenTofu.
Pre-req’s
First, we need Golang 1.19. This is what Terraform was based on at 1.5.x before, well, we know what they did at 1.6.
$ brew install go@1.19
Running `brew update --auto-update`...
==> Auto-updated Homebrew!
Updated 2 taps (homebrew/core and homebrew/cask).
==> New Formulae
biome libimobiledevice-glue orcania web-ext
blake3 libmapper tailwindcss yder
helidon llvm@16 uffizzi
==> New Casks
ava chainner cloudnet expo-orbit playdate-mirror spundle
batteryboi clinq dropshelf mutedeck reqable twelite-stage
You have 48 outdated formulae installed.
Warning: go@1.19 has been deprecated because it is not supported upstream!

==> Caveats
go@1.19 is keg-only, which means it was not symlinked into /home/linuxbrew/.linuxbrew,
because this is an alternate version of another formula.
If you need to have go@1.19 first in your PATH, run:
echo 'export PATH="/home/linuxbrew/.linuxbrew/opt/go@1.19/bin:$PATH"' >> ~/.profile

🍺 /home/linuxbrew/.linuxbrew/Cellar/go@1.19/1.19.13: 12,486 files, 593MB
==> Running `brew cleanup go@1.19`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
==> Caveats
==> go@1.19
go@1.19 is keg-only, which means it was not symlinked into /home/linuxbrew/.linuxbrew,

As suggested, I’ll add to my path
$ echo 'export PATH="/home/linuxbrew/.linuxbrew/opt/go@1.19/bin:$PATH"' >> ~/.profile
Next, we’ll clone the repo down
$ git clone https://github.com/opentofu/opentofu.git

note: module requires Go 1.19
This first build failed and I was a bit confused. I realized i didn’t source my bashrc after installing golang 1.19.
Checking, indeed I had 1.18 still active in the path, which I quickly fixed
builder@DESKTOP-QADGF36:~/Workspaces/opentofu$ go version
go version go1.18.5 linux/amd64
builder@DESKTOP-QADGF36:~/Workspaces/opentofu$ export PATH="/home/linuxbrew/.linuxbrew/opt/go@1.19/bin:$PATH"
builder@DESKTOP-QADGF36:~/Workspaces/opentofu$ go version
go version go1.19.13 linux/amd64
Now when I build, I see no errors and a new opentofu binary exists
We can check the version
builder@DESKTOP-QADGF36:~/Workspaces/opentofu$ ./opentofu version
OpenTofu v1.6.0-dev
on linux_amd64
I’ll copy to /usr/local/bin
to make it easy to use
builder@DESKTOP-QADGF36:~/Workspaces$ sudo cp opentofu/opentofu /usr/local/bin/

Last week, we covered using GCP Infra Manager and there I used the example repo https://github.com/idjohnson/gcpimexample.
I’ll clone that down

- Installing hashicorp/google v4.83.0...
- Installed hashicorp/google v4.83.0 (signed, key ID 34365D9472D7468F)
Providers are signed by their developers.
If you'd like to know more about provider signing, you can read about it here:
https://www.placeholderplaceholderplaceholder.io/docs/cli/plugins/signing.html
OpenTofu has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that OpenTofu can guarantee to make the same selections by default when
you run "tofu init" in the future.
OpenTofu has been successfully initialized!
You may now begin working with OpenTofu. Try running "tofu plan" to see
any changes that are required for your infrastructure. All OpenTofu commands
should now work.
If you ever set or change modules or backend configuration for OpenTofu,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
With no values passed or set explicitly in my values file, running a plan will prompt me for the bucket and project
builder@DESKTOP-QADGF36:~/Workspaces/gcpimexample$ opentofu plan
var.bucketname
The name of the bucket to try and create
Enter a value: idjtestbucket33445566
var.projectid
The name of the GCP project
Enter a value: myanthosproject2
Planning failed. OpenTofu encountered an error while generating this plan.
╷

I’ll next run gcloud auth application-default login
which fires up Firefox in X
This required user, login and 2FA which was nice to see all the security controls work

──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
Note: You didn't use the -out option to save this plan, so OpenTofu can't guarantee to take exactly these actions if
you run "tofu apply" now.
Since I neglected to save the plan, if I try and apply, it will just ask me the same questions again. Let’s save the plan this time
builder@DESKTOP-QADGF36:~/Workspaces/gcpimexample$ opentofu plan -out tofu.plan
var.bucketname
The name of the bucket to try and create
Enter a value: freshbrewedtest33445566
var.projectid
The name of the GCP project
Enter a value: myanthosproject2
OpenTofu used the selected providers to generate the following execution plan. Resource actions are indicated with the
following symbols:
+ create
OpenTofu will perform the following actions:
# google_storage_bucket.auto-expire will be created

Plan: 1 to add, 0 to change, 0 to destroy.
──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
Saved the plan to: tofu.plan
To perform exactly these actions, run the following command to apply:
tofu apply "tofu.plan"
I can now apply it without issue:
builder@DESKTOP-QADGF36:~/Workspaces/gcpimexample$ opentofu apply tofu.plan
google_storage_bucket.auto-expire: Creating...
google_storage_bucket.auto-expire: Creation complete after 1s [id=freshbrewedtest33445566]
Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
Just as before, we can go to the cloud console to see our bucket was indeed created as well as the lifecycle policies
Note: a consequence of not using remote state management is that my tfstate file is sitting locally and I would need to protect and/or manage in some fashion

Cleanup
Let’s now say we are done with this bucket.
I was a bit bummed it didn’t just pick up my vars from the state file, but ah well.
Since opentofu destroy
is just a shorthand of opentofu apply -destroy
, i used the latter.
builder@DESKTOP-QADGF36:~/Workspaces/gcpimexample$ terraform apply -destroy -var bucketname=freshbrewedtest33445566 -va
r projectid=myanthosproject2
google_storage_bucket.auto-expire: Refreshing state... [id=freshbrewedtest33445566]
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with
the following symbols:
- destroy
Terraform will perform the following actions:
# google_storage_bucket.auto-expire will be destroyed
- resource "google_storage_bucket" "auto-expire" {
- default_event_based_hold = false -> null
- force_destroy = true -> null
- id = "freshbrewedtest33445566" -> null

Plan: 0 to add, 0 to change, 1 to destroy.
Do you really want to destroy all resources?
Terraform will destroy all your managed infrastructure, as shown above.
There is no undo. Only 'yes' will be accepted to confirm.
Enter a value: yes
google_storage_bucket.auto-expire: Destroying... [id=freshbrewedtest33445566]
google_storage_bucket.auto-expire: Destruction complete after 1s
Apply complete! Resources: 0 added, 0 changed, 1 destroyed.
And as before, I can see the bucket is removed
And just to be certain that despite having to pass in values via “-var”, it was really operating against just that which it had created, I went ahead and tried to use the same local terraform to destroy a bucket not created by this plan/apply.
That just shows that, indeed, it is operating against tfstate file
Summary
Today we built OpenTofu locally:
builder@DESKTOP-QADGF36:~/Workspaces/gcpimexample$ opentofu version
OpenTofu v1.6.0-dev
on linux_amd64
+ provider registry.terraform.io/hashicorp/google v4.83.0
Using GoLang 1.19 and the Github repo. We tested a simple plane we used with GCP earlier this week. We confirmed we can create and destroy with ease.
Next, we’ll look at using this in an automated pipeline, even building a container image to reduce the needs for recompiles.
What I believe - Hashi and the BUSL Change
When Hashi moved all of their licensed products to the BSL 1.1 on August 10th it was a smack in the face to all the Open Source work that has gone out there. That August 10th blog post attempted to align the BUSL change in with the type that, say, MongoDB did:
BSL 1.1 is a source-available license that allows copying, modification, redistribution, non-commercial use, and commercial use under specific conditions. With this change we are following a path similar to other companies in recent years. These companies include Couchbase, Cockroach Labs, Sentry, and MariaDB, which developed this license in 2013. Companies including Confluent, MongoDB, Elastic, Redis Labs, and others have also adopted alternative licenses that include restrictions on commercial usage. In all these cases, the license enables the commercial sponsor to have more control around commercialization.
But that isn’t quite accurate. We can see from the details of the SSPL it’s key point is a poison pill for those that would try to make cloud copies in that they would be required to opensource everything if they did - like a mini-GPL bomb. Frankly, I like that approach. MariaDB is all in on GPL v2 with the exception of their Enterprise product, for which they used the BSL just for MaxScale 2.0.0 to 2.0.4 : BSL 1.1 for these projects (linked to MaxScale 2). For MariaDB MaxScale 2.0.0 until 2.0.4, BSL 1.0 . MariaDB Server will continue to be licensed under GPL in perpetuity, while its connectors will continue to be under the LGPL.
Armon went on to write:
Our implementation of BSL includes additional usage grants that allow for broadly permissive use of our source code. We believe this will offer a fair and sustainable way for HashiCorp to share its source code widely, for free use. We consulted with OSS licensing experts and other industry stakeholders when developing our license, so that our efforts would be in line with industry practices.
Our first goal with this change is to minimize the impact to our community, partners, and customers. We will continue to publish source code and updates for HashiCorp products to our GitHub repository and distribution channels.
End users can continue to copy, modify, and redistribute the code for all non-commercial and commercial use, except where providing a competitive offering to HashiCorp. Partners can continue to build integrations for our joint customers. We will continue to work closely with the cloud service providers to ensure deep support for our mutual technologies. Customers of enterprise and cloud-managed HashiCorp products will see no change as well.
This is the part that has folks up in arms: “except where providing a competitive offering to HashiCorp”. Use the source code, some of which you might have written, provided you don’t compete with us. And as time goes forward, Hashicorp covers progressively more and more ground.
What if someone like Harness.io put in Terraform changes but then was sued for using Terraform code in their product because now Hashi has Waypoint, a pipelining app? And we can see from the Hashicorp hosted discussion that followed, many had the same question:
In this long thread, Flux almost dropped Terraform and spoke of switching away from Vault API usage because, according to the CNCF, BUSL is not Open-Source and is not allowed.
Look, I do not begrudge anyone for wanting to protect their IP. We’ve seen what the cloud providers do to smaller companies. I’ve been in the room where we didn’t opt for Redis (Enterprise) because we could just get the equivalent from GCP or Amazon; which was ripped off in it’s entirety from Redis (corp).
But where the BUSL model really gets rough is with Terraform.
Terraform, to be specific, is only as big as it is, and as adopted as it is, because of the contributions of others. If GCP stops updating their TF modules, I stop using Terraform. I don’t use Terraform to, I dunno, enjoy playing with Opa and Plans - I use it fundamentally to build cloud infrastructure.
Consider, if you will, what would happen if Apple decided too many people made money off Safari so the Safari browser would only surf Apple owned products or fully free websites - would you still use Safari? What if it was illegal to use a MacBook to build a website that competed with an Apple product, would you consider buying a new one - or more importantly, releasing your software to run on said MacBook?
That’s where I really challenge the “Customers of enterprise and cloud-managed HashiCorp products will see no change as well” line; We have seen change already with the creation of OpenTofu with large backing - the Linux Foundation is behind this - even the CNCF might be adopting it - the folks that keep Kubernetes marching forward. And only a few weeks after the announcement, Google unveiled the Infra Manager that aims to obliviate the need for Terraform Enterprise/Cloud when standing up infrastructure in GCP.
Google’s offering is not as good as TFE/TF Cloud right now, let’s be real, but I now have a non-Hashi solution to handling GCP infrastructure. With some creative pipelining in Github Workflows or AzDO I could bring it close to equivocating TFE or at least TF Cloud.
Pulumi, perhaps the little train that could, a company that made me chuckle by hanging out in the lobby at the last Hashiconf handing out fliers (and putting signs on all the stoplights around the venue), threw a bit of shade pointing out they are Apache 2.0 and plan to stay that way
Frankly, I think Hashi is close to losing the battle here unless they do an immediate about-face on the BUSL. I believe Terraform, in the form of OpenTofu will keep going - and be fully supported by the cloud providers. I think modules from Amazon, Google, Microsoft and more will pin to OpenTF not to HashiTF.
I saw all this before - I saw the world swing from Hudson to Jenkins, from MySQL to MariaDB, from Java to OpenJDK and C#. How many companies have you been to, as a software person, still using Oracle Java? using Oracle Hudson? Using MySQL Enterprise? Does the enterprise customer want to pin to an offering from one provider who has changed the pricing several times already?
In that forum, I saw several questions around the fear of a Vader move (I am altering the deal…)

One can get defensive and just say this is all just a bunch of Open Source people griping, but the stock has taken a hit since
I need to pause here and say I have drafted this post for a bit and gotten feedback from several trusted architects and colleagues. I have wrestled internally with what to say.
I will simply say that the License change truely disappointed me. I can add that this is likely my last Hashiconf as the love has dissipated. I’ve cashed in my chits every year with every employer to go to Hashiconf since 2018, but I’ll go somewhere else next year, maybe Kubecon. I’ve been so all in for years.
I have spoken on their behalf to large rooms, as recently as two weeks ago (in partnership with a vendor, Datadog, of which I’m still all-in).

I have been their steadfast advocate trying to land Vault, Consul and Terraform Enterprise at a variety of companies. I believe I have been a really valuable ally for what was then, a smaller open-source company looking to grow. But I just cannot anymore.
Don’t get me wrong, I still think TFE, as of this point in time right now, is the strongest IaC Enterprise play. But now I would now advise caution in its adoption. I might propose alternatives. I might now invite others into the room of architects and push for pilots of Pulumi, GCP Infra or just doing pipelines on our own.
Maybe I’m just one guy. But I’ll stay steadfast in my belief that Open-Source (not source available) is the strongest play always. And when companies start Open Source then break that trust, as Oracle did with Java and Hudson, or Atlassian (technically Bob Swift) did with the JIRA CLI, then those strong (often senior in organizations) allies stop being allies. It’s a very hard trust to win back.
