=head1 NAME

Paws::Batch::ContainerOverrides

=head1 USAGE

This class represents one of two things:

=head3 Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. 
Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::Batch::ContainerOverrides object:

  $service_obj->Method(Att1 => { Command => $value, ..., Vcpus => $value  });

=head3 Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::Batch::ContainerOverrides object:

  $result = $service_obj->Method(...);
  $result->Att1->Command

=head1 DESCRIPTION

The overrides that should be sent to a container.

=head1 ATTRIBUTES


=head2 Command => ArrayRef[Str|Undef]

The command to send to the container that overrides the default command
from the Docker image or the job definition.


=head2 Environment => ArrayRef[L<Paws::Batch::KeyValuePair>]

The environment variables to send to the container. You can add new
environment variables, which are added to the container at launch, or
you can override the existing environment variables from the Docker
image or the job definition.

Environment variables must not start with C<AWS_BATCH>; this naming
convention is reserved for variables that are set by the AWS Batch
service.


=head2 InstanceType => Str

The instance type to use for a multi-node parallel job.

This parameter isn't applicable to single-node container jobs or for
jobs running on Fargate resources and shouldn't be provided.


=head2 Memory => Int

This parameter indicates the amount of memory (in MiB) that's reserved
for the job. It overrides the C<memory> parameter set in the job
definition, but doesn't override any memory requirement specified in
the C<ResourceRequirement> structure in the job definition.

This parameter is supported for jobs that run on EC2 resources, but
isn't supported for jobs that run on Fargate resources. For these
resources, use C<resourceRequirement> instead.


=head2 ResourceRequirements => ArrayRef[L<Paws::Batch::ResourceRequirement>]

The type and amount of resources to assign to a container. This
overrides the settings in the job definition. The supported resources
include C<GPU>, C<MEMORY>, and C<VCPU>.


=head2 Vcpus => Int

This parameter indicates the number of vCPUs reserved for the
container.It overrides the C<vcpus> parameter that's set in the job
definition, but doesn't override any vCPU requirement specified in the
C<resourceRequirement> structure in the job definition.

This parameter is supported for jobs that run on EC2 resources, but
isn't supported for jobs that run on Fargate resources. For Fargate
resources, you can only use C<resourceRequirement>. For EC2 resources,
you can use either this parameter or C<resourceRequirement> but not
both.

This parameter maps to C<CpuShares> in the Create a container
(https://docs.docker.com/engine/api/v1.23/#create-a-container) section
of the Docker Remote API (https://docs.docker.com/engine/api/v1.23/)
and the C<--cpu-shares> option to docker run
(https://docs.docker.com/engine/reference/run/). Each vCPU is
equivalent to 1,024 CPU shares. You must specify at least one vCPU.

This parameter isn't applicable to jobs that run on Fargate resources
and shouldn't be provided. For jobs that run on Fargate resources, you
must specify the vCPU requirement for the job using
C<resourceRequirements>.
