AWS Configure Bash One Liner
If you want to automate you should use files rather than CLI. Your CLI only write those files.
➜ cat ~/.aws/config
[profile_1]
output = json
region = eu-west-1
[profile_2]
output = json
region = eu-west-1
➜ cat ~/.aws/credentials
[profile_1]
aws_access_key_id =
aws_secret_access_key =
[profile_2]
aws_access_key_id =
aws_secret_access_key =
For those inclined to use bash, the following works quite well and keeps secrets out of your scripts. In addition, it will also save your input to a named profile in one go.
printf "%s\n%s\nus-east-1\njson" "$KEY_ID" "$SECRET_KEY" | aws configure --profile my-profile
If you run aws configure set help
you will see that you can supply settings individually on the command line and they will be written to the relevant credentials or config file. For example:
aws configure set aws_access_key_id AKIAI44QH8DHBEXAMPLE
You can also run this interactively to modify the default credentials:
aws configure
Or run it interactively to create/modify a named profile:
aws configure --profile qa
Note: with the first technique above, whatever command you type will appear in your history and this is not a good thing for passwords, secret keys etc. So in that case, use an alternative that does not cause the secret parameter to be logged to history, or prevent the entire command being logged to history.
I think this is the answer in one line
aws configure set aws_access_key_id $YOUR_ACCESS_KEY_ID; aws configure set aws_secret_access_key $YOUR_SECRET_ACCESS_KEY; aws configure set default.region $YOUR_AWS_DEFAULT_REGION
