customDNS	CustomDNS	The custom DNS configuration.
customRuntimeConfig	CustomRuntimeConfig	The configuration for the custom runtime.
description	string	A description of the function.	my function

environmentVariables	object	The environment variables that are available to the function at runtime.
	string		value1
gpuConfig	GPUConfig	The GPU configuration for the function.
handler	string	The function handler, which is the entry point for execution. The format varies by runtime.	index.handler
instanceConcurrency	integer	The maximum number of concurrent requests that a single function instance can process.	1
instanceLifecycleConfig	InstanceLifecycleConfig	The configuration for instance lifecycle hooks.
internetAccess	boolean	Specifies whether the function can access the internet.	true
layers	array	A list of layer ARNs to apply to the function. Files in a layer with a lower array index overwrite files with the same name from a layer with a higher array index.
	string	The layer ARN.	acs:fc:cn-beijing:186824xxxxxx:layers/fc_layer/versions/1
logConfig	LogConfig	The logging configuration. Function-generated logs are written to the specified Logstore.
memorySize	integer	The memory size for the function, in megabytes (MB). The value must be a multiple of 64. The available memory options depend on the function's instance type.	512
nasConfig	NASConfig	The NAS configuration. This allows the function to access specified NAS resources.
ossMountConfig	OSSMountConfig	The OSS mount configuration.
role	string	The ARN of the RAM role that Function Compute assumes to get permissions to access other cloud services. For example, Function Compute requires permissions to write function logs to your Logstore or to obtain an STS token for the function to access other services.	acs:ram::188077086902****:role/fc-test
runtime	string	The function's runtime.	nodejs14
timeout	integer	The execution timeout for the function, in seconds. The value must be at least 1. The default is 3. If the timeout is reached, Function Compute terminates the execution.	60
tracingConfig	TracingConfig	The tracing configuration. This allows you to record request latency, view function cold start time, and trace time spent on code execution.
vpcConfig	VPCConfig	The VPC configuration. This allows the function to access resources in the specified VPC.
disableOndemand	boolean	Specifies whether to disable on-demand instances for the function. If set to true, Function Compute will only use provisioned instances to run the function.
sessionAffinity	string	The session affinity policy for function invocation requests. Use `MCP_SSE` for MCP SSE protocol affinity, `GENERATED_COOKIE` for cookie-based affinity, or `HEADER_FIELD` for header-based affinity. If unspecified or set to `NONE`, Function Compute uses the default scheduling policy.	MCP_SSE
enableLongLiving	boolean	Specifies whether to enable long-living provisioned instances for GPU-accelerated functions. If this feature is enabled, Function Compute does not inject an STS token into the function instances.
instanceIsolationMode	string	The instance isolation mode.
sessionAffinityConfig	string	The configuration for the specified `sessionAffinity` policy, provided as a JSON string. The object structure within the string depends on the policy. For example, use an `MCPSSESessionAffinityConfig` object for `MCP_SSE` affinity, a `CookieSessionAffinityConfig` object for cookie-based affinity, or a `HeaderFieldSessionAffinityConfig` object for header-based affinity.	{\"sseEndpointPath\":\"/sse\", \"sessionConcurrencyPerInstance\":20}
idleTimeout	integer	The idle timeout for the function instance, in seconds. An instance is terminated after being idle for this duration.	100
disableInjectCredentials	string	Specifies whether to disable STS token injection. Valid values: `None`: The token is injected into all locations. `Env`: The token is not injected into environment variables. `Request`: The token is not injected into the request context or header. `All`: The token is not injected into any location.
polarFsConfig	PolarFsConfig	The PolarFS configuration. This allows the function to access specified PolarFS resources.
juiceFsConfig	JuiceFsConfig	The JuiceFS configuration. This allows the function to access specified JuiceFS resources.
