Blog Post: How to use Terraform with Kubernetes (July 21 - TBD)

<!-- PLEASE READ: See https://about.gitlab.com/handbook/marketing/blog/ for details on the blog process. Unless you are just suggesting a blog post idea, you will need to create the formatted merge request for your blog post in order for it to be reviewed and published. -->

## Triage (REQUIRED)

The Inbound Marketing team prioritizes requests that drive results and meet our [goals of generating organic traffic and inquiries](https://about.gitlab.com/handbook/marketing/inbound-marketing/#goals). 

Please note that there is a different process for when you want to announce something via the blog. Please see [announcement requests](https://about.gitlab.com/handbook/marketing/corporate-marketing/#requests-for-announcements) in the handbook and open an announcement request issue instead of a blog post issue. 

Generally speaking, engineering blog posts that are tutorials/how-tos or which share how we built or debugged something, are popular with our audience. **If your proposed blog post is aligned with our [Attributes of a successful blog post guidelines](https://about.gitlab.com/handbook/marketing/blog/#attributes-of-a-successful-blog-post), you can skip straight to your [proposal](#proposal).** 

If you are pitching something outside of those guidelines, please fill in the below to help us prioritize. You can check out [examples of high- and low-performing blog posts to help with your rationale](https://about.gitlab.com/handbook/marketing/inbound-marketing/content/editorial-team/#top-performing-blog-posts).

## Proposal

Related to: https://twitter.com/kubermatic/status/1374357606412779522?s=27

Our blog post about GitOps, terraform, etc. was one of the most read posts we've ever published so I know that this will be a hot topic. I'm not totally sure what the angle here is, I will leave that up to you @abuango, but I think that if we do something like "How to use Terraform with Kubernetes and GitLab" that could be great.
