Container runnable.

Fields

image_uri: String

Required. The URI to pull the container image from.

commands: Vec<String>

Required for some container images. Overrides the CMD specified in the container. If there is an ENTRYPOINT (either in the container image or with the entrypoint field below) then these commands are appended as arguments to the ENTRYPOINT.

entrypoint: String

Required for some container images. Overrides the ENTRYPOINT specified in the container.

volumes: Vec<String>

Volumes to mount (bind mount) from the host machine files or directories into the container, formatted to match --volume option for the docker run command—for example, /foo:/bar or /foo:/bar:ro.

If the TaskSpec.Volumes field is specified but this field is not, Batch will mount each volume from the host machine to the container with the same mount path by default. In this case, the default mount option for containers will be read-only (ro) for existing persistent disks and read-write (rw) for other volume types, regardless of the original mount options specified in TaskSpec.Volumes. If you need different mount settings, you can explicitly configure them in this field.

options: String

Required for some container images. Arbitrary additional options to include in the docker run command when running this container—for example, --network host. For the --volume option, use the volumes field for the container.

block_external_network: bool

If set to true, external network access to and from container will be blocked, containers that are with block_external_network as true can still communicate with each other, network cannot be specified in the container.options field.

username: String

Required if the container image is from a private Docker registry. The username to login to the Docker registry that contains the image.

You can either specify the username directly by using plain text or specify an encrypted username by using a Secret Manager secret: projects/*/secrets/*/versions/*. However, using a secret is recommended for enhanced security.

Caution: If you specify the username using plain text, you risk the username being exposed to any users who can view the job or its logs. To avoid this risk, specify a secret that contains the username instead.

password: String

Required if the container image is from a private Docker registry. The password to login to the Docker registry that contains the image.

For security, it is strongly recommended to specify an encrypted password by using a Secret Manager secret: projects/*/secrets/*/versions/*.

Warning: If you specify the password using plain text, you risk the password being exposed to any users who can view the job or its logs. To avoid this risk, specify a secret that contains the password instead.

enable_image_streaming: bool

Optional. If set to true, this container runnable uses Image streaming.

Use Image streaming to allow the runnable to initialize without waiting for the entire container image to download, which can significantly reduce startup time for large container images.

When enableImageStreaming is set to true, the container runtime is containerd instead of Docker. Additionally, this container runnable only supports the following container subfields: imageUri, commands\[\], entrypoint, and volumes\[\]; any other container subfields are ignored.

For more information about the requirements and limitations for using Image streaming with Batch, see the image-streaming sample on GitHub.

Trait Implementations

impl Clone for Container

fn clone(&self) -> Container

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Container

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Container

fn default() -> Self

Returns the “default value” for a type.

impl Message for Container

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Container

fn eq(&self, other: &Container) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
