[LINUX] Let's upload S3 files with CLI

Introduction

You can create S3 on the management console screen, but I haven't created it by operating it with CLI, so I tried this time.

procedure

Check AWS CLI Check if the AWS CLI is installed with the following command.

aws --version

S3 permission settings Click IAM> Roles> Roles for which you want to set permissions. Press the "Attach Policy" button. Enter s3 in the policy filter and select "Amazon Full Access". Press Attach Policy. It is displayed that it has been attached.

Set default region

$ aws configure
AWS Access Key ID [None]: 
AWS Secret Access Key [None]:
Default region name [None]: ap-northeast-1
Default output format [None]: json

Nothing is specified for "AWS Access Key ID [None]:" and "AWS Secret Access Key [None]:".

Create S3 bucket ``` $ aws mb s3://hoge * The hoge part is a duplicate load, so make it unique. $aws s3 ls * Check if the baguette was created. ``` You can also check it on the management console.

Upload files to S3 bucket Upload any image on the internet. In the case of Chrome browser, right-click the image and select "Copy image address". Create a work directory in your home directory to work with. Download by specifying the image address as an argument with the wget command in the work directory.

$ mkdir ~/work
$ cd ~/work
$ wget https://hogehoge/hogehoge.png

Execute the s3 ls command by specifying the bucket. Check if there is an image.

$ aws s3 ls s3://hoge

You can also check if there is an image on the management console.

Set public access authority from CLI with the following command.

$ aws s3api put-object-acl --acl public-read --bucket filename--key image name(hoge.png)

Check if there is a permission setting in the access control list.

$ aws s3api get-object-acl --bucket filename--key image name(hoge.png)

Click the object URL in the management console and check if the image can be opened. When the above procedure is followed, the image is displayed.

If you press the object URL and it says "Access Denied" and the image is not displayed, click the "Publish" button in the outline of the object and it will be displayed.
