Deploying a Simple Amazon S3 Bucket
S3 buckets are the foundational blocks within Amazon S3. They’re containers that hold files, are defined at the region level, and live across all regions of AWS. In this tutorial, we’re going to deploy our first S3 bucket.
Step 1 - Navigate to the S3 Console
1.1 - From the AWS Console, search for “S3.”
1.2 - From the drop-down menu, click on “S3.”
Step 2 - Create a New S3 Bucket
2.1 - From the S3 Console, click on “Create bucket.”
Step 3 - Specify Core Parameters for an Amazon S3 Bucket
3.1 - From the dropdown menu labeled “AWS Region,” select the region in which you’d like to create the bucket.
3.2 - From the menu labeled “Bucket type,” select “General Purpose” as the bucket type.
3.3 - In the “Bucket name” field, enter a name for your bucket. It’s important to note that every bucket on AWS must have a unique name. That’s in the entirety of AWS; not just your account.
3.4 - [OPTIONAL] If you’d like to clone an existing bucket, you may choose a bucket to use as the main image for the one you’re creating.
3.5 - From the menu labeled “Object Ownership,” select “ACLs disabled” unless you’d like to create access control lists that regulate the traffic into the bucket you’re creating. Note that there are different ways in which you can allow or disallow traffic into the S3 bucket. We will discuss these methods in a different section within this tutorial.
3.6 - In the “Block Public Access settings for this bucket” section, choose “Block all public access.” There aren’t many instances where you’d want your bucket to be accessible via a public network using modern architectures. If you need to setup such access, it’s advisable to use gateways to direct traffic to the bucket.
3.7 - “Bucket Versioning” refers to keeping track of the state of the bucket in an effort to assign a numerical version. This feature is similar to what you’d find in software version control. It’s entirely optional.
3.8 - [OPTIONAL] Create a tag(s) for your new bucket.
3.9 - In the “Default encryption” section, choose the type of encryption you’d like to have for your bucket. We recommend using the Amazon S3 managed keys.
3.10 - Under “Bucket Key” specify if you’d like to use a key provided by Amazon S3 by selecting “Enable.”
3.11 - Click on “Create bucket” to finalize the creation process.
Finalized Bucket List
You should see your new bucket in the list displayed on the main S3 Console, as shown below.
Uploading Objects to an Amazon S3 Bucket
Now that we have a bucket on Amazon S3, it’s time to put it to good use!
Step 1 - Navigate to the Bucket Console
1.1 - From the S3 Console, select the bucket you’d like to upload to.
Step 2 - Uploading an Object to an S3 Bucket
2.1 - [OPTIONAL] You can organize the objects using Folders just as you would on your machine. To do so, create a folder by clicking the “Create folder” button.
2.2 - Click on the “Upload” button to enter the upload menu for your bucket.
Step 3 - Uploading an Object to an S3 Bucket
3.1 - You have two options when it comes to uploading files and folders on this screen. You can either drag and drop or you can click the buttons to select the files or folders of your choice.
3.2 - Choose a file and or folder you’d like to upload to your bucket. In this example, we’re uploading a .png image file.
3.3 - Click on “Open” to confirm the selection you made.
3.4 - Verify that your file and / or folder is now listed under the “Files and folders” section.
3.5 - [OPTIONAL] Note that you can select and remove the file and / or folder if you’ve selected the wrong one(s) by using the “Remove” option.
3.6 - Click the “Upload” button at the bottom of the page to confirm the upload of files and folders that are on the list.
Finalized Amazon S3 Bucket File Upload
You should get confirmation that your file and/or folder has been uploaded to the bucket on the home page.
