passing access and secret key aws cli

I am trying to embed access and secret key along with aws cli. e.g.

aws ec2 describe-instances --aws-access-key <access_key> --aws-secret-key <secret_key>

Also tried with -o and -w options for access and secret key respectively. It says : Unknown option aws-access-key and aws-secret-key

You can provide keys on the command line via envars:

AWS_ACCESS_KEY_ID=ABCD AWS_SECRET_ACCESS_KEY=EF1234 aws ec2 describe-instances

See http://docs.aws.amazon.com/cli/latest/topic/config-vars.html#credentials

EDIT: @wisbucky noted this could leave secrets in your command history. One way around this in bash at least I think is to prepend your command with a blank space and the command should not propagate to your bash history.

You can use it like this one;

aws configure set aws_access_key_id <yourAccessKey>
aws configure set aws_secret_access_key <yourSecretKey>

For more information, use this one;

aws configure set help

General pattern is;

aws <command> help
aws <command> <subcommand> help

I hope it helps!

Summarizing the aws doc, there several ways to pass credentials to the command line. Please note that there are no command line options to pass in the the key and secret key directly. The "provider chain" is used instead.

In my bash scripts, I often use environment variables. To add a tiny bit of security, I source a file containing the variables rather than putting them in the script. With named profiles, it's even easier.

The provider chain is:

command line options: specify region, output format, or profile
Environment variables: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN
The AWS credentials file – located at ~/.aws/credentials on Linux, macOS, or Unix, or at C:\Users\USERNAME .aws\credentials on Windows. This file can contain multiple named profiles in addition to a default profile.
The CLI configuration file – typically located at ~/.aws/config on Linux, macOS, or Unix, or at C:\Users\USERNAME .aws\config on Windows. This file can contain a default profile, named profiles, and CLI specific configuration parameters for each.
Container credentials – provided by Amazon Elastic Container Service on container instances when you assign a role to your task.
Instance profile credentials – these credentials can be used on EC2 instances with an assigned instance role, and are delivered through the Amazon EC2 metadata service.

You can also use aws configure:

$ aws configure
AWS Access Key ID [None]: xxxxxxxxxxxxxxxxxxxxxxxxx
AWS Secret Access Key [None]: xxxxxxxxxxxxxxxxxxxxxxxxx

Its the best way and more secure to use IAM roles. There you can set specific rights to this instance and what it has to access in your account.

Depending on what awscli version you use you can use describe-instances in a couple ways.

Like this one:

ec2din -O your-key -W your-secret-key --region your-region

Also there is a big difference when you install awscli with pip install or from pkg like ubuntu deb package.

ec2din is a short command to ec2-describe-instances

More examples here: ec2-describe-instances

I had to access multiple accounts on Amazon....so my solution:

under: ~/.aws/config

[default] aws_access_key_id = xxxx aws_secret_access_key = xxxxxx region=sa-east-1 output=text

[profile prof1] region=us-east-1 output=text aws_access_key_id = yyy aws_secret_access_key = yyyyy

[profile prof2] region=us-east-1 output=text aws_access_key_id = wwwwww aws_secret_access_key = wwwww

..and then when evoke the aws CLI, i passed the parameter "--profile" as:

/usr/local/bin/aws ec2 describe-security-groups --group-ids sg-xxxx --profile prof2

...that it!

You should store your credentials to ~/.aws/config file (or .aws/credentials)

More info how to setup it http://docs.aws.amazon.com/cli/latest/reference/configure/index.html

Also as alternative way you can create IAM role and certain policy and set it to you ec2 instance where you will use aws cli, then you won't need any credentials setup there

To access aws through cli,

aws configure

Another method is to use echo with aws configure as a one-liner:

echo -ne '%s\n%s\n%s\n%s\n' <access_key> <security_key> <region> <output> | aws configure
