To create an Amazon S3 bucket with Terraform, you'll need to define a resource in your Terraform configuration file. This resource will be used to create the S3 bucket.
The resource type for an S3 bucket in Terraform is aws_s3_bucket. You can create a new resource with this type and specify the required properties, such as the bucket name and region.
You can also specify additional properties, like versioning and server-side encryption, to customize the S3 bucket's behavior. For example, you can enable versioning to keep a record of every change made to the bucket's contents.

Configuration Options
Creating an Amazon S3 bucket requires careful consideration of various configuration options.
You can choose between a standard and a versioned storage class, with the latter allowing for the storage of multiple versions of an object.
When creating a bucket, you can also choose between a public and a private access policy, with the former making your bucket accessible to anyone on the internet.
This is important to consider, as a public bucket can expose your data to unauthorized access.

Options
When creating a new bucket, you have several options to consider.
The canned ACL to apply to the bucket can be set to private, public-read, public-read-write, or authenticated-read.
There are specific permissions associated with each of these options.
The private option allows no one to access the bucket, while the public-read option allows anyone to read the bucket's objects.
The public-read-write option allows anyone to read and write the bucket's objects.
Authenticated-read allows anyone with the correct credentials to read the bucket's objects.
Here are the possible values for the canned ACL:
- private
- public-read
- public-read-write
- authenticated-read
Understanding these options is crucial to ensuring the security and accessibility of your bucket.
Manage ACL with Public Access Block
In Terraform, you can manage the public access control list on your S3 bucket using the aws_s3_bucket_public_access_block resource.
By default, public ACL is allowed, but you can restrict it by setting the value to true.
The aws_s3_bucket_public_access_block resource allows you to block public ACLs, public policies, and ignore public ACLs.
You can see in the example that block_public_acls, block_public_policy, ignore_public_acls, and restrict_public_buckets are all set to true.
Here are the options you can set to restrict public access:
Example Use Cases
An Amazon S3 bucket is a versatile storage solution that can be used for a variety of purposes, such as hosting static websites, storing backups, and serving media files.
You can create a static website by uploading your website's files to an S3 bucket and setting the bucket's permissions to allow public access. This is especially useful for small projects or prototypes where you don't need a full-fledged web server.
For example, if you upload a file named "index.html" to your S3 bucket, it will be served as the homepage of your website. This is because S3 buckets can serve files directly, eliminating the need for a web server.
To store backups, you can upload your files to an S3 bucket and set the bucket's versioning to retain multiple versions of your files. This ensures that you can recover from any data loss or corruption.

Examples
You need to have the AWS CLI installed and configured to use these examples. See the Getting started guide in the AWS CLI User Guide for more information.
A different take: Aws Cli Create S3 Bucket
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide.
You can create a bucket named my-bucket using the following command. The command creates a bucket named my-bucket.
To create a bucket with owner enforced, you need to use the bucket owner enforced setting for S3 Object Ownership. This setting can be found in the Controlling ownership of objects and disabling ACLs section of the Amazon S3 User Guide.
You can create a bucket outside of the us-east-1 region by specifying the LocationConstraint. For example, to create a bucket in the eu-west-1 region, you would use the eu-west-1 region.

Shipping Logs
Shipping logs to Amazon S3 is a common practice, especially when working with AWS services. Many AWS services have the built-in capability to ship their logs to Amazon S3 object storage.
Some examples of AWS services that can ship logs to S3 include AWS CloudTrail, Elastic Load Balancing (ELB), Amazon CloudFront, and Amazon CloudWatch. These services collect and log data that can be useful for troubleshooting and monitoring.
AWS customers can use the AWS CLI to interact with these services and ship the log data they collect to an S3 bucket. From there, customers can set up a security data lake or investigate CloudFront logs.
Here are some examples of AWS services that can ship logs to S3:
- AWS CloudTrail
- Elastic Load Balancing (ELB)
- Amazon CloudFront
- Amazon CloudWatch
By shipping logs to S3, customers can automate the process of ingesting log data into their bucket using the AWS CLI. This can be done through scheduling a Cron Job with AWS CLI in Linux or monitoring and shipping logs with Watchdog and watchmedo.
Using Terraform
Using Terraform to create an S3 bucket is relatively simple. However, it's not recommended for uploading thousands of files into the S3 bucket, as Terraform is an infrastructure provisioning tool and not suited for data-intensive tasks.
Additional reading: How to Create Terraform from Existing Vm Azure
To create an S3 bucket using Terraform, you'll need to use the aws_s3_bucket resource. This involves specifying the region, bucket name, and access control list (ACL). The S3 bucket name we're going to use is spacelift-test1-s3, and we'll set the ACL to private.
Here are the Terraform commands you'll need to run:
- $ terraform init
- $ terraform plan
- $ terraform apply
These commands will initialize Terraform, run a plan to see what resources will be added or changed, and finally apply the configuration to create the S3 bucket in AWS.
Step 4
Now that you've reached Step 4, it's time to fill up the required information in all the sections of the wizard. Each section has been provided with the information explaining what it is and its purpose, so be sure to go through that information in case of any confusion.
To start, enter the bucket name in the "General Configuration" section. Make sure the name satisfies all the Bucket naming rules, as it cannot be changed after creating the bucket.

While choosing an AWS Region, select a region close to you or your target audience to minimize latency and costs, and address regulatory requirements.
Here are the settings you'll need to consider for each section:
- "Object Ownership" section: Choose between "ACLs disabled" and "ACLs enabled" settings.
- "Block Public Access settings for this bucket" section: Select the Block Public Access settings you want to apply to the bucket.
- "Bucket Versioning" section: Enable versioning if you need to keep multiple versions of an object in the same bucket.
- "Tags" section: Add tags to your bucket for tracking storage costs, grouping resources, and more.
- "Default encryption" section: Enable server-side encryption for objects stored in the bucket.
- "Advanced Setting" section: Enable object lock property if required.
Fill in each section carefully, reading the information provided, and then click the "Create bucket" button to submit the wizard.
Using Terraform
Using Terraform is a great way to create infrastructure in AWS, but it's not suitable for data-intensive tasks like uploading thousands of files into an S3 bucket.
Terraform is an infrastructure provisioning tool, and it's best to use it for creating resources like S3 buckets, rather than for tasks that require uploading large amounts of data.
To get started with Terraform, you'll need to create a main.tf file and a version.tf file for AWS and Vault version.
The Terraform aws_s3_bucket resource is used to create an S3 bucket, and it has several parameters that you'll need to specify, including the region, bucket name, and access control list.
If this caught your attention, see: How to Create File in Google Drive
Here are the parameters you'll need to specify for the Terraform aws_s3_bucket resource:
Once you've specified the parameters, you can apply the Terraform configuration using the Terraform commands: terraform init, terraform plan, and terraform apply.
Command Line Interface
To use the AWS CLI, you'll need an AWS account and valid IAM credentials. You can install the latest version on your machine, and the AWS CLI user guide contains instructions for installing on Linux, MacOS, or Windows.
The recommended method for accessing the AWS CLI is to install it on your machine, and you can also access it through AWS CloudShell, a browser-based shell that provides AWS customers with access to the CLI and other development tools.
Once you have installed AWS CLI, you can use the "AWS S3 Copy" or "AWS S3 Sync" commands to execute a one-time action of moving data up to be indexed.

CLI Basics
The CLI is a powerful tool for managing AWS resources, as seen in the tutorial on creating S3 buckets with AWS CLI.
You can use the CLI to create an Amazon S3 bucket with a single command, which is a huge time-saver.
The CLI allows you to configure an IAM role that can write to an S3 bucket, which is necessary for pushing data to the bucket.
This is achieved by using an instance profile to associate the IAM role with an existing EC2 instance.
The permissions in the associated IAM role can then be used to push data to the created S3 bucket.
The CLI instructions in the tutorial include links to AWS docs for doing the same tasks with the AWS console, which can be helpful for visual learners.
You can use the CLI to create an instance profile and associate it with an existing EC2 instance, which is a crucial step in the process.
The CLI is a great tool for automating tasks and reducing the need for manual intervention, as seen in the tutorial on creating S3 buckets.

Automating Tasks
Automating tasks is a crucial part of managing your Amazon S3 bucket.
You can automate the process of ingesting log data into your Amazon S3 bucket using AWS CLI.
AWS CLI can be used to schedule a Cron Job in Linux to automate log ingestion.
A Cron Job is a Linux utility that allows you to schedule tasks to run at specific times or intervals.
You can also use Watchdog and watchmedo to monitor and ship logs into your Amazon S3 bucket.
Watchdog is a tool that monitors a directory for changes and can be used to automate log ingestion.
Here are two strategies for automating log ingest with AWS CLI:
- Scheduling a Cron Job with AWS CLI in Linux
- Monitoring and shipping logs with Watchdog and watchmedo
