How do I install the packages from this Tap?

This Tap follows standard Homebrew commands, for more information, please refer to the Homebrew Documentation. Updating homebrew itself is done via the following command:

brew update

The above command will update homebrew itself and this comamnd should always be run prior to attempts to install or update any packages with brew.

Installing the Tap

The macOS AMIs provided by AWS already come with Homebrew installed and this Tap “pretapped”. To manually install the Tap, use the the brew tap command:

brew tap aws/homebrew-aws

Removing the Tap

If this Tap needs to be removed for any reason, Homebrew includes a specific command for this. (Note: This will only remove the Tap and it will preserve anything that was previously installed)

brew untap aws/homebrew-aws

Updating Packages

To update a specific package (Keg or Cask) that has been installed from this tap. Kegs use the default brew upgrade <package> command, while Casks have their own sub-command: brew upgrade --cask <package>.

For example:

Type	Update Command
Full System	brew upgrade
Keg	brew upgrade amazon-efs-utils
Cask	brew upgrade --cask amazon-ena-ethernet-dext

Installing Packages

There are two primary ways to install software from the Tap. Kegs use the default brew install <package> command, while Casks have their own sub-command: brew install --cask <package>.

For example:

Type	Install Command
Keg	brew install amazon-efs-utils
Cask	brew install --cask amazon-ena-ethernet-dext

Removing Packages

Removing software is similar to installing software. Kegs and Casks now use the same brew remove <package> command.

For example:

Type	Uninstall Command
Keg	brew remove amazon-efs-utils
Cask	brew remove amazon-ssm-agent
