Can Upload to S3 Using Aws Cli

Upload File to Amazon S3 Bucket using AWS CLI Command Line Interface

In this AWS tutorial, I want to share how an AWS builder or a programmer can suspend auto scaling group processes which enables users to disable automobile scaling for a catamenia of time instead of deleting the auto-scaling group from their AWS resources.

In this AWS CLI Command Line Interface tutorial, I want to testify developers how to install the Amazon AWS CLI tool and configure AWS CLI for authenticating on Amazon Web Services, proxy configuration and authentication on web proxies, etc. After programmers configure AWS CLI tool, and so they volition find a few basic samples of using AWS CLI with Amazon S3 service like uploading file to S3 bucket, synchronizing a local folder to Amazon S3 saucepan and listing contents of a saucepan folder, etc.

Install AWS CLI Tool

In this AWS tutorial for programmers, I desire to show how AWS CLI commands tin can exist used to re-create file or files of a folder into an Amazon S3 bucket folder. First we have to install the AWS CLI tool. The latest version of AWS CLI is version 2. If you accept installed previously an older version of the AWS CLI control line interface tool, you tin choose to uninstall it first and then install the new AWS CLI software version as shown in this tutorial.

To uninstall previous AWS CLI version, developers can use the "Apps and Features" Windows x app. Just search for Apps and features in search box and when the application is displayed search for "aws", if the AWS CLI tool is previously installed you lot can run across it in the filtered list of applications.

If yous have installed AWS Command Line Interface CLI version ane, and so you can uninstall this software earlier installing the version 2 of it. Information technology is non possible to run both versions of AWS CLI side by side.

Click Uninstall to remove the AWSC CLI version ane

Download new version, AWS CLI version 2, you lot can use the download AWS CLI Version ii link

After you consummate AWS CLI v2 installer file download, run the setup program AWSCLIV2.msi
The setup completes within a few minutes later your selections as seen in post-obit screenshots.

Click Next button for next step where you corroborate the license agreement.

Adjacent step is selecting the installation binder on your Windows PC for the AWS CLI software

Click Install for starting the setup process

Installation takes only a few minutes

Setup complete. Developers tin can now use AWS CLI to build applications that collaborate with Amazon Web Services using the provided APIs.

When the installation is complete, programmers can bank check the version of AWS CLI software installed by execution following command on a new Command Prompt screen
aws --version

aws --version

Code

The output was as follows when I ran the AWS CLI version check control:
aws-cli/ii.0.3 Python/3.seven.5 Windows/ten botocore/2.0.0dev7

AWS CLI Configuration

Before using the AWS CLI commands, programmers accept to configure their AWS account details, proxy settings, proxy authentication details, etc.
Let's start with AWS CLI Configuration every bit described at AWS documentation
Run below "configure" control on a Windows Command Prompt screen.

aws configure

Code

Now with "AWS Configure" command really we are creating or updating the default profile that volition be used for authenticating to AWS service.
We define the AWS Access Key ID and the Secret Access Key for validating the account.
Additionally, we provide the default region for services like AWS S3. If you don't know the AWS region code but know the region name, you can refer to AWS Region Names and Codes for Programmatic Access

When the default AWS CLI profile is created, the commands that we will execute afterward volition be authorized on AWS with this information.

At present allow's attempt uploading sample files to an Amazon S3 saucepan on your AWS business relationship.
If you don't know the AWS S3 buckets you know you can log on to your AWS Console and cheque for the possible S3 buckets that your account has required permissions for list, uploading and reading files from.

I take a saucepan named "aws-datavirtuality" that I can apply for this AWS CLI tutorial with its default region I stated while configuring the default AWS CLI profile.

I will use the copy command "cp" which is used to copy or upload files from a local folder on your computer to an AWS S3 saucepan or vice versa.
Developers can besides utilize the copy command to copy files between two Amazon S3 bucket folders

aws s3 cp cities.csv s3://aws-datavirtuality

Code

For more on AWS CLI cp Re-create command, please refer to AWS CLI Reference - cp

I more annotation here, on command prompt I take navigated to the Windows binder where the sample csv file that I want to upload to Amazon S3 bucket exists. If you cheque the screenshot, you can realize that I am not in the root folder of the C drive. Of course information technology is possible to provide the full path oof the sample file besides. It is up to you.

If yous are using a web proxy and you have non withal configured your proxy details and authentication data, information technology is possible that you will experince below proxy mistake after the AWS CLI copy cp command is executed.

upload failed: .\cities.csv to s3://aws-datavirtuality/cities.csv Failed to connect to proxy URL: "http://USER:Password1*@proxy-url.com:8080"

Amazon Web Services documentation provides a good article on HTTP Proxy Configuration
Basically, if you know the proxy addresses and ports you tin can use following "setx HTTP PROXY" and "setx HTTPS PROXY" commands

setx HTTP_PROXY http://your-proxy-accost.com:8080
setx HTTPS_PROXY http://your-proxy-address.com:8080

Lawmaking

If you lot don't know which proxy you are using, y'all can check it just on your Internet Explorer's settings. Follow the path:
Net Options > Connections > LAN settings

The proxy address is either explicitely attack "Proxy server" and "Port" text boxex or defined in the configuration script file.

Of form about cases you also need to authenticate on the proxy server.
In this instance, by adding your domain user and domain countersign, y'all tin can build and run following command on Windows Command Prompt.

setx HTTP_PROXY http://domainuser:password@your-proxy-address.com:8080
setx HTTPS_PROXY http://domainuser:password@your-proxy-address.com:8080

Code

Try once more on a new Command Prompt screen. Peculiarly if y'all practice configurational changes on Control Prompt for AWS CLI tool, I experienced that I take to launch a new screen to take changes into account.

C:\My\Veri>aws s3 cp cities.csv s3://aws-datavirtuality

Lawmaking

Information technology is not a surprise if the developers get following SSL validation fault during file upload using AWS CLI cp command execution.

upload failed: .\cities.csv to s3://aws-datavirtuality/cities.csv SSL validation failed for https://aws-datavirtuality.s3.eu-fundamental-ane.amazonaws.com/cities.csv [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed document in document concatenation (_ssl.c:1076)

In this case, programmers can use "--no-verify-ssl" option at the end of the control to ignore the SSL validation errors.

aws s3 cp cities.csv s3://aws-datavirtuality --no-verify-ssl

Code

The execution output of the to a higher place AWS CLI cp command is as follows in my case.

C:\Programme Files\Amazon\AWSCLIV2\urllib3\connectionpool.py:1004: InsecureRequestWarning: Unverified HTTPS request is existence made to host 'your-proxy-address.com'. Adding document verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
upload: .\cities.csv to s3://aws-datavirtuality/cities.csv

Although you become a alert message, upload succeeds

Upload Local File to Amazon S3 Bucket using AWS CLI cp Command

If developers wish to upload file to a subfolder instead of directly copying information technology to the root folder of the Amazon S3 bucket, they can use:

aws s3 cp cities.csv s3://aws-datavirtuality/sampledata/ --no-verify-ssl


Code

Or use full path of file

C:\>aws s3 cp c:\my\veri\cities.csv s3://aws-datavirtuality/sampledata/ --no-verify-ssl


Code

Use quotes if file name of folder name has spaces within

aws s3 cp "c:\my\share\New Text Document.txt" s3://aws-datavirtuality/exam/ --no-verify-ssl

Code

Upload Folder Contents to Amazon S3 Bucket using AWS CLI sync Command

If yous want to upload all contents of a file binder with a single AWS CLI control, instead of using copy command CP, folder synchronization command SYNC tin can be used as seen in following samples

aws s3 sync c:\my\veri\ s3://aws-datavirtuality/sampledata/ --no-verify-ssl
aws s3 sync c:\my\share\ s3://aws-datavirtuality/test/ --no-verify-ssl

Code

SYNC command enables programmers using AWS CLI command to upload all contents of a file folder and grants the ability of multiple file upload to an AWS S3 bucket or to a folder in a S3 bucket.

List S3 Bucket Folder Contents using AWS CLI ls Command

To list contents of an Amazon S3 saucepan or a subfolder in an AWS S3 saucepan, developers can simply use AWS CLI ls command. Hither is a sample of using ls (listing) control.

aws s3 ls s3://aws-datavirtuality --no-verify-ssl

Code

C:\Program Files\Amazon\AWSCLIV2\urllib3\connectionpool.py:1004: InsecureRequestWarning: Unverified HTTPS asking is being made to host 'your-proxy-address.com'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/avant-garde-usage.html#ssl-warnings

Please refer to Amazon CLI documentation for more detailed usage of AWS CLI ls command options.

Download File from Amazon S3 Bucket using AWS CLI cp Command

If the developers needs to download a file from Amazon S3 bucket folder instead of uploading a new file to AWS S3, then he or she can change the target and source and execute the same AWS CLI cp Copy command as follows:

aws s3 cp s3://mys3bucket/myfolder/filetodownload.txt downloadedfile.txt --no-verify-ssl

Code

Download Amazon S3 Bucket Folder Contents using AWS CLI synch Command

If you want to download all files and subfolder contents of an Amazon S3 bucket binder, following AWS CLI synch control can exist used:

aws s3 sync s3://mys3bucket/myfolder/ c:\localfolder\subfolder --no-verify-ssl
