Method Details

getImage

@Stability(Stable)
@NotNull
default ContainerImage getImage()

The image that this container will run.

Specified by:

getImage in interface IEksContainerDefinition

getVolumes

@Stability(Stable)
@NotNull
default List<EksVolume> getVolumes()

The Volumes to mount to this container.

Automatically added to the Pod.

Specified by:

getVolumes in interface IEksContainerDefinition

See Also:

• https://kubernetes.io/docs/concepts/storage/volumes/

getArgs

@Stability(Stable)
@Nullable
default List<String> getArgs()

An array of arguments to the entrypoint.

If this isn't specified, the CMD of the container image is used. This corresponds to the args member in the Entrypoint portion of the Pod in Kubernetes. Environment variable references are expanded using the container's environment. If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1)" and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1)." $$ is replaced with $, and the resulting string isn't expanded. or example, $$(VAR_NAME) is passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists.

Specified by:

getArgs in interface IEksContainerDefinition

See Also:

• https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/

getCommand

@Stability(Stable)
@Nullable
default List<String> getCommand()

The entrypoint for the container.

This isn't run within a shell. If this isn't specified, the ENTRYPOINT of the container image is used. Environment variable references are expanded using the container's environment. If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1)" and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1)." $$ is replaced with $ and the resulting string isn't expanded. For example, $$(VAR_NAME) will be passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists.

The entrypoint can't be updated.

Specified by:

getCommand in interface IEksContainerDefinition

• https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/pod-v1/#entrypoint

getCpuLimit

@Stability(Stable)
@Nullable
default Number getCpuLimit()

Default: - No CPU limit

Specified by:

See Also:

• https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

getCpuReservation

@Stability(Stable)
@Nullable
default Number getCpuReservation()

The soft limit of CPUs to reserve for the container Must be an even multiple of 0.25.

The container will given at least this many CPUs, but may consume more.

At least one of cpuReservation and cpuLimit is required. If both are specified, then cpuLimit must be at least as large as cpuReservation.

Default: - No CPUs reserved

Specified by:

getCpuReservation in interface IEksContainerDefinition

See Also:

• https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

getEnv

@Stability(Stable)
@Nullable
default Map<String,String> getEnv()

The environment variables to pass to this container.

Note: Environment variables cannot start with "AWS_BATCH". This naming convention is reserved for variables that AWS Batch sets.

Specified by:

getEnv in interface IEksContainerDefinition

getGpuLimit

@Stability(Stable)
@Nullable
default Number getGpuLimit()

The hard limit of GPUs to present to this container.

If your container attempts to exceed this limit, it will be terminated.

If both gpuReservation and gpuLimit are specified, then gpuLimit must be equal to gpuReservation.

Default: - No GPU limit

Specified by:

getGpuLimit in interface IEksContainerDefinition

See Also:

• https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

getGpuReservation

@Stability(Stable)
@Nullable
default Number getGpuReservation()

The soft limit of CPUs to reserve for the container Must be an even multiple of 0.25.

The container will given at least this many CPUs, but may consume more.

If both gpuReservation and gpuLimit are specified, then gpuLimit must be equal to gpuReservation.

Default: - No GPUs reserved

Specified by:

getGpuReservation in interface IEksContainerDefinition

See Also:

• https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

getImagePullPolicy

@Stability(Stable)
@Nullable
default ImagePullPolicy getImagePullPolicy()

The image pull policy for this container.

Default: - `ALWAYS` if the `:latest` tag is specified, `IF_NOT_PRESENT` otherwise

Specified by:

getImagePullPolicy in interface IEksContainerDefinition

See Also:

• https://kubernetes.io/docs/concepts/containers/images/#updating-images

getMemoryLimit

@Stability(Stable)
@Nullable
default Size getMemoryLimit()

The amount (in MiB) of memory to present to the container.

If your container attempts to exceed the allocated memory, it will be terminated.

Must be larger that 4 MiB

At least one of memoryLimit and memoryReservation is required

Note: To maximize your resource utilization, provide your jobs with as much memory as possible for the specific instance type that you are using.

Default: - No memory limit

Specified by:

getMemoryLimit in interface IEksContainerDefinition

See Also:

• https://docs.aws.amazon.com/batch/latest/userguide/memory-management.html

getMemoryReservation

@Stability(Stable)
@Nullable
default Size getMemoryReservation()

The soft limit (in MiB) of memory to reserve for the container.

Your container will be given at least this much memory, but may consume more.

Must be larger that 4 MiB

When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first.

At least one of memoryLimit and memoryReservation is required. If both are specified, then memoryLimit must be equal to memoryReservation

Note: To maximize your resource utilization, provide your jobs with as much memory as possible for the specific instance type that you are using.

Default: - No memory reserved
