@Generated("software.amazon.awssdk:codegen") public final class SystemControl extends Object implements SdkPojo, Serializable, ToCopyableBuilder<SystemControl.Builder,SystemControl>

A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.

We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task. This task also uses either the awsvpc or host network mode. It does it for the following reasons.

  • For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.

  • For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter and that of all containers of any tasks running on that container instance.

      public final String namespace()

      The namespaced kernel parameter to set a value for.

      Returns:
      The namespaced kernel parameter to set a value for.

    • value

      public final String value()

      The namespaced kernel parameter to set a value for.

      Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced" , and Sysctls that start with "fs.mqueue.*"

      Valid network namespace values: Sysctls that start with "net.*"

      All of these values are supported by Fargate.

    • toBuilder

      public SystemControl.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<SystemControl.Builder,SystemControl>
      Returns:
      a builder for type T

    • builder

      public static SystemControl.Builder builder()

    • serializableBuilderClass

      public static Class<? extends SystemControl.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
