Configure Completion

$ awsctx completion --shell zsh > /path/to/completions/_awsctx

Please replace /path/to with a path in your environment. bash, elvish and fish are also available as a --shell option

How it Works

Login

Authorize your shell by some ways with specified profile name. Then, you get ~/.aws/credentials like

[foo]
aws_access_key_id = XXXXXXXXXXX
aws_secret_access_key = XXXXXXXXXXX
aws_session_token = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

[bar]
aws_access_key_id = YYYYYYYYYYY
aws_secret_access_key = YYYYYYYYYYY
aws_session_token = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Update the default profile by CLI

use-context update ~/.aws/credentials to contain default profile that the values are same as specified in the option.

$ awsctx use-context -p foo

e.g. the above commands updates credentials as the below.

[foo]
aws_access_key_id = XXXXXXXXXXX
aws_secret_access_key = XXXXXXXXXXX
aws_session_token = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

[bar]
aws_access_key_id = YYYYYYYYYYY
aws_secret_access_key = YYYYYYYYYYY
aws_session_token = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

[default]
aws_access_key_id = XXXXXXXXXXX
aws_secret_access_key = XXXXXXXXXXX
aws_session_token = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
