Important Note:
Terraform Exams are updated regularly. Whenever there is a new update released in exams, there are certain topics that you will notice that are not part of the course. It takes some amount of time to record the delta videos. In the mean-time, we have created a document that has all of these deltas topics.
1. Requirements for publishing module in Terraform Registry
Ensure that you know the list of requirements for publishing modules in the Terraform registry.
https://www.terraform.io/docs/registry/modules/publish.html
2. List:
list(...): a sequence of values identified by consecutive whole numbers starting with zero. The keyword list is a shorthand for list(any), which accepts any element type as long as every element is the same type
We cannot use all words within variable names. Terraform reserves some additional names that can no longer be used as input variable names for modules. These reserved names are:
count
depends_on
for_each
lifecycle
providers
source
3. Air Gapped
If terraform needs to be installed in an environment without internet access, the installation is referred to as air-gapped
https://www.terraform.io/docs/enterprise/install/installer.html.
4. Index Function
index finds the element index for a given value in a list.
https://www.terraform.io/docs/configuration/functions/index.html
5. Terraform Enterprise
Before mid-2019, all distributions of Terraform Cloud used to be called Terraform Enterprise; the self-hosted distribution was called Private Terraform Enterprise (PTFE).
Terraform Enterprise supports the following data storage:
PostgresSQL
Any S3-compatible object storage service, GCP Cloud Storage or Azure blob storage meets Terraform Enterprise's object storage requirements.
If you already run your own Vault cluster in production, you can configure Terraform Enterprise to use that instead of running its own internal Vault instance.
https://www.terraform.io/docs/enterprise/before-installing/index.html
6. VCS Provider Support for Terraform Provider
GitHub.com
GitHub.com (OAuth)
GitHub Enterprise
GitLab.com
GitLab EE and CE
Bitbucket Cloud
Bitbucket Server
Azure DevOps Server
Azure DevOps Services
https://www.terraform.io/docs/cloud/vcs/index.html
7. Zipmap function
https://www.terraform.io/docs/configuration/functions/zipmap.html
8 Supported Format for Comments
The Terraform language supports three different syntaxes for comments:
#
//
/* and */
https://www.terraform.io/docs/configuration/syntax.html
Miscellaneous Pointer
GitHub is not the supported backend type in Terraform.
https://www.terraform.io/docs/backends/types/index.html
When running terraform init, the plugins are downloaded in the sub-directory of the present working directory at the path of .terraform/plugins
API and CLI access for Terraform Cloud can be managed through API tokens that can be generated from Terraform Cloud UI.
Terraform uses Parallelism to reduce the time it takes to create the resource. By default, this value is set to 10
Terraform recommends using an Indent two spaces for each nesting level.
ami = "abc123"
instance_type = "t2.micro"
,
Following are the two CLI configuration file for Terraform:
.terraformrc
terraform.rc
https://www.terraform.io/docs/commands/cli-config.html
The terraform get command is used to download and update modules mentioned in the root module.
The Sentinel command-line interface (CLI) allows for the developing and testing of policies outside of a particular Sentinel implementation
