This section describes the type of information you can include in a configuration file to customize the software on your EC2 instances running Linux. For general information about customizing and configuring your Elastic Beanstalk environments, see Configuring Elastic Beanstalk environments. For information about customizing software on your EC2 instances running Windows, see Customizing software on Windows servers.

On Amazon Linux 2 platforms, instead of providing files and commands in .ebextensions configuration files, we highly recommend that you use Buildfile. Procfile, and platform hooks whenever possible to configure and run custom code on your environment instances during instance provisioning. For details about these mechanisms, see Extending Elastic Beanstalk Linux platforms.

Watch your environment's events while developing and testing configuration files. Elastic Beanstalk ignores a configuration file that contains validation errors, like an invalid key, and doesn't process any of the other keys in the same file. When this happens, Elastic Beanstalk adds a warning event to the event log.

Elastic Beanstalk currently supports the following package managers: yum, rubygems, python, and rpm. Packages are processed in the following order: rpm, yum, and then rubygems and python. There is no ordering between rubygems and python. Within each package manager, package installation order isn't guaranteed. Use a package manager supported by your operating system.

Elastic Beanstalk supports two underlying package managers for Python, pip and easy_install. However, in the syntax of the configuration file, you must specify the package manager name as python. When you use a configuration file to specify a Python package manager, Elastic Beanstalk uses Python 2.7. If your application relies on a different version of Python, you can specify the packages to install in a requirements.txt file. For more information, see Specifying dependencies using a requirements file.

Within each package manager, each package is specified as a package name and a list of versions. The version can be a string, a list of versions, or an empty string or list. An empty string or list indicates that you want the latest version. For rpm manager, the version is specified as a path to a file on disk or a URL. Relative paths are not supported.

You can use the groups key to create Linux/UNIX groups and to assign group IDs. To create a group, add a new key-value pair that maps a new group name to an optional group ID. The groups key can contain one or more group names. The following table lists the available keys.

You can use the files key to create files on the EC2 instance. The content can be either inline in the configuration file, or the content can be pulled from a URL. The files are written to disk in lexicographic order.

A six-digit octal value representing the mode for this file. Not supported for Windows systems. Use the first three digits for symlinks and the last three digits for setting permissions. To create a symlink, specify 120xxx, where xxx defines the permissions of the target file. To specify permissions for a file, use the last three digits, such as 000644.

The specified commands run as the root user, and are processed in alphabetical order by name. By default, commands run in the root directory. To run commands from another directory, use the cwd option.

If you use an array, you don't need to escape space characters or enclose command parameters in quotes. Each array element is a single command argument. Don't use an array to specify multiple commands.

(Optional) A boolean value that determines if other commands should run if the command contained in the command key fails (returns a nonzero value). Set this value to true if you want to continue running commands even if the command fails. Set it to false if you want to stop running commands if the command fails. The default value is false.

You can use the services key to define which services should be started or stopped when the instance is launched. The services key also allows you to specify dependencies on sources, packages, and files so that if a restart is needed due to files being installed, Elastic Beanstalk takes care of the service restart.

You can use the container_commands key to execute commands that affect your application source code. Container commands run after the application and web server have been set up and the application version archive has been extracted, but before the application version is deployed. Non-container commands and other customization operations are performed prior to the application source code being extracted.

The specified commands run as the root user, and are processed in alphabetical order by name. Container commands are run from the staging directory, where your source code is extracted prior to being deployed to the application server. Any changes you make to your source code in the staging directory with a container command will be included when the source is deployed to its final location.

You can use leader_only to only run the command on a single instance, or configure a test to only run the command when a test command evaluates to true. Leader-only container commands are only executed during environment creation and deployments, while other commands and server customization operations are performed every time an instance is provisioned or updated. Leader-only container commands are not executed due to launch configuration changes, such as a change in the AMI Id or instance type.

(Optional) Only run the command on a single instance chosen by Elastic Beanstalk. Leader-only container commands are run before other container commands. A command can be leader-only or have a test, but not both (leader_only takes precedence).

The Commands API allows extension developers to define specific commands, and bind them to a defaultkey combination. Each command an extension accepts must be declared as properties of the"commands" object in the extension's manifest.

An object value allows the extension developer to customize the keyboard shortcut for eachplatform. When providing platform-specific shortcuts, valid object properties are default,chromeos, linux, mac, and windows.

A string used to provide the user with a short description of the command's purpose. This stringappears in extension keyboard shortcut management UI. Descriptions are required for standardcommands, but are ignored for Action commands.

The following keys are usable command shortcuts. Key definitions are case sensitive. Attempting toload an extension with an incorrectly cased key will result in a manifest parse error atinstallation time.

By default, commands are scoped to the Chrome browser. This means that when the browser does nothave focus, command shortcuts are inactive. Beginning in Chrome 35, extension developers canoptionally mark a command as "global". Global commands also work while Chrome does not have focus.

Keyboard shortcut suggestions for global commands are limited to Ctrl+Shift+[0..9]. This is aprotective measure to minimize the risk of overriding shortcuts in other applications since if, forexample, Alt+P were to be allowed as global, the keyboard shortcut for opening a print dialogmight not work in other applications.

Commands allow extensions to map logic to keyboard shortcuts that can be invoked by the user. At itsmost basic, a command only requires a command declaration in the extension's manifest and a listenerregistration as shown in the following example.

As described in the Usage section, you can also map a command to an extension'saction. The following example injects a content script that shows analert on the current page when the user either clicks the extension's action or triggers thekeyboard shortcut.

If an extension attempts to register a shortcut that is already used by another extension, thesecond extension's shortcut won't register as expected. You can provide a more robust end userexperience by anticipating this possibility and checking for collisions at install time.

Promises are supported in Manifest V3 and later, but callbacks are provided for backward compatibility. You cannot use both on the same function call. The promise resolves with the same type that is passed to the callback.

Commands may also be entered in a multiplayer server's console, but are not preceded by a / when entered this way. A server owner running commands in this way is often referred to as "ghosting".

Most commands require the executor have a high enough permission level. That means most commands are available in the singleplayer world only if cheats are enabled, and available in multiplayer server only if the player is an operator. See permission level for details.

In Bedrock Edition, cheats can be toggled at any time in the "Game" tab of the settings menu. Enabling cheats in a world permanently prevents players from unlocking achievements in that world, even if cheats are later turned off.

All supported versions of Windows and Windows Server have a set of Win32 console commands built in. This set of documentation describes the Windows Commands you can use to automate tasks by using scripts or scripting tools.

Windows has two command-line shells: the Command shell and PowerShell. Each shell is a software program that provides direct communication between you and the operating system or application, providing an environment to automate IT operations.

The Command shell was the first shell built into Windows to automate routine tasks, like user account management or nightly backups, with batch (.bat) files. With Windows Script Host, you could run more sophisticated scripts in the Command shell. For more information, see cscript or wscript. You can perform operations more efficiently by using scripts than you can by using the user interface. Scripts accept all commands that are available at the command line.
