Constructor Details

#initialize(init_process_enabled: nil, max_swap: nil, shared_memory_size: nil, swappiness: nil) ⇒ LinuxParametersProps

Returns a new instance of LinuxParametersProps.

Parameters:

  • init_process_enabled (Boolean, nil) (defaults to: nil) —

    Specifies whether to run an init process inside the container that forwards signals and reaps processes.

  • max_swap (AWSCDK::Size, nil) (defaults to: nil) —

    The total amount of swap memory a container can use.

  • shared_memory_size (Numeric, nil) (defaults to: nil) —

    The value for the size of the /dev/shm volume.

  • swappiness (Numeric, nil) (defaults to: nil) —

    This allows you to tune a container's memory swappiness behavior.

Instance Attribute Details

#init_process_enabled ⇒ Boolean? (readonly)

Note:

Default: false

Specifies whether to run an init process inside the container that forwards signals and reaps processes.

Returns:

  • (Boolean, nil)

def init_process_enabled
  @init_process_enabled
end

#max_swap ⇒ AWSCDK::Size? (readonly)

Note:

Default: No swap.

The total amount of swap memory a container can use.

This parameter will be translated to the --memory-swap option to docker run.

This parameter is only supported when you are using the EC2 launch type. Accepted values are positive integers.

Returns:

def max_swap

end

#shared_memory_size ⇒ Numeric? (readonly)

Note:

Default: No shared memory.

The value for the size of the /dev/shm volume.

Returns:

  • (Numeric, nil)

def shared_memory_size
  @shared_memory_size
end

#swappiness ⇒ Numeric? (readonly)

Note:

Default: 60

This allows you to tune a container's memory swappiness behavior.

This parameter maps to the --memory-swappiness option to docker run. The swappiness relates to the kernel's tendency to swap memory. A value of 0 will cause swapping to not happen unless absolutely necessary. A value of 100 will cause pages to be swapped very aggressively.

This parameter is only supported when you are using the EC2 launch type. Accepted values are whole numbers between 0 and 100. If a value is not specified for maxSwap then this parameter is ignored.

Returns:

  • (Numeric, nil)
