Managing Functions - Scaleway Elements Serverless
Serverless Overview
Scaleway Elements Serverless Platform allows you to deploy your Functions (FaaS) and Containerized Applications (CaaS) in a managed infrastructure. Benefit from a constant availability, everywhere.
Scaleway ensures deployment, availability, scalability which allows you to save money and time. You can focus on software development instead of devOps missions.
Requirements
- You have an account and are logged into console.scaleway.com
- You have a Scaleway Serverless Namespace
Operation Procedures
Several function operations can be performed on the Serverless Plattform, these include:
Creating a Function
With Function as a Service, you can deploy lightweight units of logics, running on our infrastructure.
1 . In the side menu, click Serverless to enter the corresponding section of the console.
2 . In the list of your Serverless Namespaces, choose the namespace you want to use.
3 . Click on Create a Function. The creation page displays.
4 . Enter the function code. You can either use the inline code editor to edit your code directly from your browser or upload a *.zip archive by choosing the Code entry type from the first drop-down menu.
Choose the desired runtime from the second drop-down menu. Currently, Serverless provides runtimes for node8, node10, python2, python3, and golang.
Set the Handler for your function and edit your code, or upload your *.zip archive.
5 . Choose a name for the function and add an optional description.
6 . Set the resources for the function, depending on its requirements. Resources define the performance characteristics of your function. They are allocated to your function at runtime.
7 . Optionally configure specific environment variables (Database host/credentials, for example), which are safely encrypted and stored in our database. Environment variables defined for a function will be injected into it together with the namespace’s variables.
8 . Set the privacy policies of the function. Privacy Policies define whether a function can be executed anonymously or protected via an authentication mechanism provided by Scaleway.
9 . If required, configure advanced options like triggers. Adding triggers to your function will make it possible for you to handle events coming from other sources, such as CRON (time-based jobs), MQTT queues, and more.
10 . Click Create a function to deploy it.
Managing a Function
1 . In the side menu, click Serverless to enter the corresponding section of the console.
2 . In the list of your Serverless Namespaces, choose the namespace you want to use.
3 . The list of your functions displays, click on the name of the function you want to manage.
4 . Edit the function’s code either by using the inline code editor or choose to upload a *.zip archive by selecting the option from the first drop-down menu. If required, the handle name of the function can be edited.
5 . Assign resources for your function. Resources define the performance characteristics of your function. They are allocated to your function at runtime.
6 . Optionally configure specific environment variables. Environment variables defined for a function will be injected into it together with the namespace’s variables.
7 . Click on Deploy a function.
8 . The function information is available from the Function Information tab. It displays the status, privacy policies, region, endpoint and optionally the description of the function:
Modifying a Functions Privacy Policies
Privacy Policies define whether a function can be executed anonymously, or protected via an authentication mechanism provided by Scaleway.
1 . In the side menu, click Serverless to enter the corresponding section of the console.
2 . In the list of your Serverless Namespaces, choose the namespace you want to use.
3 . The list of your functions displays, click on the name of the function you want to manage.
4 . Click on the Function Settings tab.
5 . Set the privacy policy for the function. It can either be Public or Private.
Deleting a Function
In case a function is no longer needed, it can be deleted from the Scaleway console.
1 . In the side menu, click Serverless to enter the corresponding section of the console.
2 . In the list of your Serverless Namespaces, choose the namespace you want to use.
3 . The list of your functions displays, click on the name of the function you want to manage.
4 . Click on the Function Settings tab.
5 . Click on Delete function to delete the function. Be careful as this is irreversible. All data will be destroyed.
