Overview

The Linux capabilities to add or remove from the default Docker configuration for a container defined in the task definition. For more detailed information about these Linux capabilities, see the

capabilities(7)][1: Linux manual page.

The following describes how Docker processes the Linux capabilities specified in the add and drop request parameters. For information about the latest behavior, see [Docker Compose: order of cap_drop and cap_add] in the Docker Community Forum.

When the container is a privleged container, the container capabilities are all of the default Docker capabilities. The capabilities specified in the add request parameter, and the drop request parameter are ignored.
When the add request parameter is set to ALL, the container capabilities are all of the default Docker capabilities, excluding those specified in the drop request parameter.
When the drop request parameter is set to ALL, the container capabilities are the capabilities specified in the add request parameter.
When the add request parameter and the drop request parameter are both empty, the capabilities the container capabilities are all of the default Docker capabilities.
The default is to first drop the capabilities specified in the drop request parameter, and then add the capabilities specified in the add request parameter.

Instance Attribute Details

#add ⇒ `Array<String>`

The Linux capabilities for the container that have been added to the default configuration provided by Docker. This parameter maps to CapAdd in the docker container create command and the --cap-add option to docker run.

<note markdown=“1”> Tasks launched on Fargate only support adding the SYS_PTRACE kernel capability.

#drop ⇒ `Array<String>`

The Linux capabilities for the container that have been removed from the default configuration provided by Docker. This parameter maps to CapDrop in the docker container create command and the --cap-drop option to docker run.
