Mounting a bucket to a container
You can mount Yandex Object Storage buckets to a container. Mounting a bucket automatically creates a new container revision.
To mount buckets to a container:
-
In the management console
, go to the folder with your container. -
From the list of services, select Serverless Containers.
-
Select the container.
-
Navigate to the Editor tab.
-
In the Settings section, select or create a new service account with one of these roles:
storage.viewer
to only read data from the mounted bucket.storage.uploader
to read and write data from/to the mounted bucket.
-
Under Mounted buckets:
-
Click Add bucket.
-
Specify the following in the field:
-
Mount path: Absolute mount path. Use this path to access the directory the bucket will be mounted to.
Do not use this path for anything other than an empty directory; otherwise, the container initialization may result in an error, and the mounted buckets will become unavailable.
-
Bucket: Bucket you want to mount. Create a new bucket if needed.
-
Directory: Bucket directory that will be mounted to the container. Leave this field empty to mount the entire bucket.
-
-
Enable Read-only to disable writing to the bucket. With this option on, data from the mounted bucket will be read-only.
To mount an additional bucket to the container, click Add bucket again and configure the parameters as needed.
-
-
Click Create revision.
If you do not have the Yandex Cloud CLI yet, install and initialize it.
The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name
or --folder-id
parameters.
Run this command:
yc serverless container revision deploy \
--container-name <container_name> \
--image <Docker_image_URL> \
--memory <RAM_size> \
--execution-timeout <execution_timeout> \
--service-account-id <service_account_ID> \
--command '<command_1>','<command_2>' \
--args '<key_1=value_1>','<key_2=value_2>' \
--mount type=object-storage,mount-point=<mount_path>,bucket=<bucket_name>,prefix=<directory_name>,mode=<mount_mode>
Where:
-
--container-name
: Container name. -
--image
: URL of the Docker image you are creating a container revision from in the following format:cr.yandex/<registry_ID>/<Docker_image_name>:<tag>
. -
--memory
: Required RAM. -
--execution-timeout
: Maximum container execution time before timeout. -
--service-account-id
: Service account ID. The service account needs thestorage.viewer
role to read from the bucket or thestorage.uploader
role to both read and write. -
--command
: Commands the container will run when started. Separate them by commas. It matches theENTRYPOINT
instruction in the Dockerfile. -
--args
: Arguments matching theCMD
instruction in the Dockerfile. Specify them inkey = value
format separated by commas. If you do not specify this parameter, the defaultCMD
value from the Docker image will be used. -
--mount
: Object Storage bucket mounting parameters:type
: Mounted storage type. For a bucket, the value is alwaysobject-storage
.mount-point
: Absolute mount path. Use this path to access the directory the bucket will be mounted to.bucket
: Bucket name.prefix
: Bucket folder that will be mounted to the container. Skip this field or leave it empty to mount the entire bucket.mode
: Bucket mount mode,ro
(read-only) orrw
(read and write).
To mount several buckets to the container at the same time, set the
--mount
parameter as many times as you need.

Open the Terraform configuration file and add the
mounts
section to the container description:resource "yandex_serverless_container" "test-container" { ... mounts { mount_point_path = "<mount_point>" mode = "<mount_mode>" object_storage { bucket = "<bucket_name>" prefix = "<directory_name>" } } }
Where:

: Bucket parameters:
To mount several buckets to the container at the same time, set the
mounts
section as many times as you need.

Apply the changes:
-
In the terminal, change to the folder where you edited the configuration file.
-
Make sure the configuration file is correct using the command:
terraform validate
If the configuration is correct, the following message is returned:
Success! The configuration is valid.
-
Run the command:
terraform plan
The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.
-
Apply the configuration changes:
terraform apply
-
Confirm the changes: type
yes
in the terminal and press Enter.
-
You can check the container revision update and its settings using the management console
yc serverless container revision get <container_revision_ID>
Use the deployRevision REST API method for the Container resource or the ContainerService/DeployRevision gRPC API call.
