Nas commands

The nas commands are used to perform operations on Apsara File Storage NAS (NAS), including uploading files, downloading files, and running custom commands.

💡Tips: To run the nas commands, the NAS service must be attached to Function Compute. You must take note of the following items before you use the nas commands:

  • The NAS service is activated. Fees may incur if you activate the NAS service.
  • When you perform operations on NAS, you must take note of the directory to which NAS is attached in Function Compute. For example, if NAS is attached to the /mnt/auto directory, you must specify the directory /mnt/auto when you upload and download files. Example: s nas upload ./demo.yaml /mnt/auto/.

Command description

You can run the nas -h or nas --help command to obtain the help documentation.

The nas commands include the following subcommands:

nas init command

The nas init command is used to initialize NAS. After you run the s.yaml or s.yml command to write a document, NAS resources may not be created before the project is deployed. In this case, you can run the nas init command to initialize NAS. This way, you can use NAS.

You can run the nas init -h or nas init --help command to obtain the help documentation.

The current command also supports some global parameters (such as -a/--access, --debug, etc.). For details, please refer to Serverless Devs global parameters document

Examples

If a resource description file in YAML exists, you can run the s nas init to initialize NAS. The following example shows the output of the command:

fc-deploy-test: 
  userId:      10003
  groupId:     10003
  mountPoints: 
    - 
      serverAddr: 06c1e48887-rmm92.cn-hangzhou.nas.aliyuncs.com
      nasDir:     /fc-deploy-service
      fcDir:      /mnt/auto

nas upload upload

The nas upload command is used to upload local files to NAS.

You can run the nas upload -h or nas upload --help command to view the help documentation.

Parameter description

Parameter Abbreviation Required in YAML mode Description
recursive r No
override o No

The current command also supports some global parameters (such as -a/--access, --debug, etc.). For details, please refer to Serverless Devs global parameters document

Examples

If a resource description file in YAML exists, you can run the s nas upload command to upload files. For example, you can run the s nas upload ./template.yml to /mnt/auto command to upload the local file ./template.yml to the directory /mnt/auto to which NAS is attached in Function Compute.

File [./template.yml] uploaded successfully.

If you need to upload a folder, you can add the --recursive or -r parameter to the command. Example: s nas upload ./code /mnt/auto -r.

Dir [./code] uploaded successfully.

⚠️ Note: If the file that you want to upload already exists, you need to add the --override or -o parameter to the command to overwrite the existing file.

nas download command

The nas download command is used to download files that are stored in NAS, which is attached to Function Compute.

You can run the nas download -h or nas download --help command to obtain the help documentation.

Parameter Description

Parameter Abbreviation Required in YAML mode Description

no-unzip - No Specifies that the folder is not decompressed.

The current command also supports some global parameters (such as -a/--access, --debug, etc.). For details, please refer to Serverless Devs global parameters document

Examples

If a resource description file in YAML exists, you can run the s nas download command to download a file. For example, you can run the s nas download /mnt/auto/template.yml ./ command to download the file ./template.yml that is stored in the directory /mnt/auto to which NAS is attached in Function Compute to the local directory ./.

File [/mnt/auto/template.yml] download successfully.

⚠️ Note: If the file that you want to upload already exists, you need to add the --override or -o parameter to the command to overwrite the existing file.

nas command command

The nas command command is used to run the specified commands in an instance. For example, you can run the nas command command to create a file or folder, or delete a file or folder in a function instance to which NAS is attached.

You can run the nas command -h or nas command --help command to obtain the help documentation.

The current command also supports some global parameters (such as -a/--access, --debug, etc.). For details, please refer to Serverless Devs global parameters document

Examples

If a resource description file in YAML exists, you can run the s nas command command to run the specified command in the Function Compute instance. For example, you can run the s nas command ls /mnt/auto command to view the directories in NAS:

code
template.yml

You can run the s nas command mkdir /mnt/auto/demo command to create a folder named demo in NAS.
