How to run aws configure on Amazon AWS EC2 automatically without interaction without prompt?

Question

I'm trying to set up Amazon AWS EC2 instance to talk to s3. The basic command is

aws configure

then follow the prompt to enter

AWS Access Key ID [None]: my-20-digit-id
AWS Secret Access Key [None]: my-40-digit-secret-key
Default region name [None]: us-east-1
Default output format [None]: text

However, what I really want is to have the command

aws configure

automatically without interaction, i.e., no prompt and wait for input

I know there are files at

~.aws/credentials
~.aws/config

where I put those 4 key=value pairs. And the "credentials" file looks like

[default]
aws_secret_access_key = my-40-digit-secret-key
aws_access_key_id = my-20-digit-id

while the "config" file looks like

[default]
region = us-east-1
output = text

However, with those file at ~/.aws/, I get into ~/.aws/, and at the command line, I type and enter command

aws configure

I still got the prompt to ask me

AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]:
Default output format [None]:

If I don't enter valid values at prompt, I won't be able to connect to s3, for example via command

aws s3 ls s3://mybucket

I turned help to amazon aws documentation pages. At this page, it mentions this option

"Command line options – region, output format and profile can be specified as command options to override default settings."

as the first option for aws configure

https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html

However, it didn't mention how to use the command line options. I tried something like this

aws configure --region us-east-1

but I still got

AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]:
Default output format [None]:

exactly like I have no option of "--region us-east-1"

If I try to

aws configure --aws_access_key_id my-20-digit-id --aws_secret_access_key my-40-digit-secret-key --region us-east-1

I get this

usage: aws [options] <command> <subcommand> [parameters]
aws: error: argument subcommand: Invalid choice, valid choices are:

How I can run the command

aws configure

automatically, no prompt, no interaction.

Please help! TIA

Edit and response to helloV, as the format in main post is much clearer than comment. I tried the command helloV mentioned, but I got error

aws configure set aws_access_key_id my-20-digit-id
usage: aws [options] <command> <subcommand> [parameters]
aws: error: argument subcommand: Invalid choice, valid choices are:

Thanks though. Continue on "aws configure set" On another EC2 instance where I've already set connection to s3, I enter

aws configure set region us-east-1

runs and returns to command prompt ">"

aws configure set aws_access_key_id my-20-digit-id

runs and returns to command prompt ">"

aws configure set aws_secret_access_key my-40-digit-secret-key

runs and returns to command prompt ">"

aws configure

runs but comes with prompts and waits for interaction

AWS Access Key ID [****************ABCD]:
AWS Secret Access Key [****************1234]:
Default region name [us-east-1]:
Default output format [text]:

helloV: here is my screen looks like

ubuntu@ip-11111:~/.aws$ more config
[default]
region = us-east-1
output = text
ubuntu@ip-11111:~/.aws$ more credentials
[default]
aws_secret_access_key = my-40-digit-secret-key
aws_access_key_id = my-20-digit-id
ubuntu@ip-11111:~/.aws$ aws s3 ls s3://

I got this

Unable to locate credentials. You can configure credentials by running "aws configure".

After this, I run

aws configure list
  Name                    Value             Type    Location
  ----                    -----             ----    --------
profile                <not set>             None    None
access_key                <not set>             None    None
secret_key                <not set>             None    None
region                us-east-1      config_file    ~/.aws/config

Looks like it does not check ~/.aws/credentials file, but ~/.aws/config file is in the list.

Solution 1

I figured out, finally. Use export such as

export AWS_ACCESS_KEY_ID=my-20-digit-id
export AWS_SECRET_ACCESS_KEY=my-40-digit-secret-key
export AWS_DEFAULT_REGION=us-east-1

then run

aws s3 ls s3://

would work. Don't run "aws configure" as others mentioned.

Thank you all.

Solution 2

These commands worked for me. If this doesn't works for you. Try do the first time using the interaction mode aws configure

aws --profile default configure set aws_access_key_id "my-20-digit-id"

aws --profile default configure set aws_secret_access_key "my-40-digit-secret-key"

Solution 3

You describe the file very well. Why not just create a file and put it in the right place? I just tried... it's exactly the same as running aws configure

UPDATE: You mention that you want to access S3 from EC2 instance. In this case you shouldn't be using credentials at all. You should user Roles instead
