Features

• aliases
• prompt segment

Aliases

Alias	Expression
av	aws-vault
ave	aws-vault exec
avl	aws-vault login
avll	aws-vault login -s
avli	aws-vault login in sandboxed browser profile
avs	aws-vault server
avsh	aws-vault exec $1 -- zsh
avp	list aws config / role ARNs

avli

Login in Private Browsing Window

This alias is currently only supported in OSX and Linux.

This alias will create a sandboxed browser profile after getting the temporary login URL for your AWS profile. This allows opening multiple profiles simultaneously in different browser profiles. This differs from using incognito mode, which shares the same profile across all incognito windows.

You can specify a specific browser to handle your login URL by setting AWS_VAULT_PL_BROWSER to the bundle name of the browser. By default, it will pick your default URL handler in MacOS. It supports the following browsers:

AWS_VAULT_PL_BROWSER value	Browser
org.mozilla.firefox	Firefox
org.mozilla.firefoxdeveloperedition	Firefox Developer Edition
com.google.chrome	Chrome
com.microsoft.edgemac	Edge
com.microsoft.edgemac.dev	Edge Developer Edition
com.brave.Browser	Brave
com.vivaldi.browser	Vivaldi

You can pass arbitrary parameters when launching the browser by setting the optional AWS_VAULT_PL_BROWSER_LAUNCH_OPTS environment variable. For example, if you wanted to start new avli browser windows maximized, you can set AWS_VAULT_PL_BROWSER_LAUNCH_OPTS="--start-maximized". Refer to your browser documentation for possible options.

avsh

Create a shell for a given profile.

For example, place the relevant AWS environment variables for your default profile by running:

avsh default

Prompt Segment

This prompt segment echos out the current aws-vault profile you're logged into. I use this for adding a segment into my custom agnoster theme.

For instance, this code:

prompt_aws_vault() {
  local vault_segment
  vault_segment="`prompt_aws_vault_segment`"
  [[ $vault_segment != '' ]] && prompt_segment cyan black "$vault_segment"
}

Produces this segment in my prompt:

The instructions to customize the prompt vary based on the theme you use. In some cases, you'll need to create a copy of the theme file and edit it to include the prompt segment. You can check out my custom agnoster theme to see how I updated the prompt.

Prompt Customization

You can customize the prompt segment behavior by overriding these variables:

Variable Name	Default	Description
AWS_VAULT_PL_CHAR	☁	The character to display when logged into an aws-vault profile
AWS_VAULT_PL_DEFAULT_PROFILE	default	Only show the character when logged into this profile, not the profile name

Multi Factor Authentication (MFA)

You can override the default MFA prompt by adding the AWS_VAULT_PL_MFA environment variable.

AWS_VAULT_PL_MFA value	Description	Example
inline	Enter your MFA token as an additional argument to the command.	avsh default 123456 avli default 123456
yubikey	Generate an MFA token from your Yubikey. See the docs for more information.	avsh default avsh default my-yubikey-profile avli default avli default my-yubikey-profile
