Deploy commands

The deploy command is used to deploy function resources. You can use this command to deploy on-premises resources that are specified in a YAML file to an online environment.

Command description

You can run the deploy -h or deploy --help command to query the help information.

The deploy command consists of the following subcommands:

• service: deploys only services
• function: deploys only functions
• trigger: deploys only triggers
• domain: deploys only domains

Parameters description

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 YAML resource description file exists, you can run the s deploy command to deploy resources. Sample output:

fc-deploy-test: 
  region:   cn-hangzhou
  service: 
    name: fc-deploy-service
  function: 
    name:       http-trigger-py36
    runtime:    python3
    handler:    index.handler
    memorySize: 128
    timeout:    60
  url: 
    system_url:    https://1583208943291465.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/fc-deploy-service/http-trigger-py36/
    custom_domain: 
      - 
        domain: http://http-trigger-py36.fc-deploy-service.1583208943291465.cn-hangzhou.fc.devsapp.net
  triggers: 
    - 
      type: http
      name: httpTrigger

Precautions

Take note of the following information about specific deployment scenarios:

• Only need to deploy/update code, you can add --type code parameter; only need to deploy/update configuration, you can add --type config parameter;

• Interactive operations may be involved when deploying:

  • When it is detected that the online resources are inconsistent with the last deployed resources recorded locally, it will remind you whether to use online resources or offline resources; if you do not want this interactive operation, you can add - when executing the command -use-local/--use-remote parameter, in this case, the local configuration/online configuration will be used first, for example:

  Whether online services exist	Whether online functions exist	Recorded on-premises services	Recorded on-premises functions	On-premises services to deploy	On-premises functions to deploy	Direct deployment	use-local	use-remote
  Yes	Yes	Same as online services	Same as online functions	-	-	No additional operation	Online services and functions are updated	Online services and functions remain unchanged
  Yes	No	Same as online services	-	-	-	No additional operation	Online services and functions are updated	Online services remain unchanged, and online functions are created
  No	No	-	-	-	-	No additional operation	Online services and functions are updated	Online services and functions are created
  Yes	Yes	Different from online services	Different from online functions	Same as online services	Same as online functions	No additional operation	Online services and functions are updated	Online services and functions remain unchanged
  Yes	Yes	Different from online services	Different from online functions	Different from online services	Different from online functions	Additional operation required	Online services and functions are updated	Online services and functions remain unchanged

  Online services & online functions: refers to services and functions that have been deployed;

  Locally recorded service & locally recorded function: refers to the state recorded when the deployment was performed locally last time, if it is the first time, no state is recorded;

  Original intention of function design: Since some services involve multiple team operations during deployment/update, if the default local configuration forcibly overrides the online configuration, it may cause the content to be updated through other channels/clients to become invalid. In order to More secure and standardized update function resources, so the ability to configure abnormal awareness online is introduced.

  When deploying, an example of the form of interaction is as follows:

  Local Last Deploy status => Online status
  
  description: "this is a test" => "this is a test console"
  
  ? Remote function: http-trigger-py36 is inconsistent with the config you deployed last time, deploy it with local config or remote
  config? (Use arrow keys)
  ❯ use local
  use remote
  

  At this time, it means that after the last local deployment and between the local deployment, the online function resources have been modified by other means. The modified content is description, and the content of the last deployment is this is a test , the online configuration is now this is a test console`, if you choose:

  • use local: The latest local configuration will be used by default to override the online configuration;
  • use remote: this part will not be updated;

  • When deploying, when it detects that some additional configuration needs to be added to the process, it will remind you whether to add the configuration, etc.; for example, the Python language project, the s build operation is performed before deployment, and the deployment involves Put some dependency paths into environment variables to help dependencies take effect; if you do not want interactive operations at this time, you can add -y/--assume-yes parameters;

  When deploying projects on CI/CD tools/platforms, in order to avoid the impact of interactive operations, you can consider using --use-local/use-remote and -y/-- The assume-yes parameter combination, for example, when the local configuration is explicitly preferred and all additional operations are agreed by default, resource deployment can be performed through s deploy --use-local -y.

  ⚠️ Note: When deploying a function, if the domain name is configured as auto, the system will assign a test domain name by default. This domain name is only for testing, and its stability is not guaranteed. The Serverless Devs FC component has the right to Domain name recycling and other processing, such as online business, production demand business, it is strongly recommended to bind your own custom domain name.

deploy service command

The deploy service command is a command to deploy service resources.

When executing the command deploy service -h/deploy service --help, you can get help documentation.

Permissions and policies

The permissions of the deploy command are related to the parameters that are configured in a YAML file. For more information about the configurations of fields and permissions in a YAML file, see YAML specifications.
