func ShutdownWithError

func UnmarshalBootYAML 

func UnmarshalBootYAML(raw []byte, config interface{})

UnmarshalBootYAML this function will parse boot config file with ENV and pflag overrides.

User who want to implement his/her own entry, may use this function to parse YAML config into struct. This function would also parse --rkset flags.

This function would do the following: 1: Read config file and unmarshal content into a map. 2: Read --rkset flags and override values in map unmarshalled at above step. 3: Unmarshal map into user provided struct.

[Flag]: Override boot config value with flag of rkset:

pflag.FlagSet which contains rkset as key.

Receives flattened boot config file(YAML) keys and override them in provided boot config. We follow the way of HELM does while overriding keys, refer to https://helm.sh/docs/intro/using_helm/ example:

Lets assuming we have boot config YAML file as bellow:

example-boot.yaml: gin:

  • port: 1949 commonService: enabled: true

We can override values in example-boot.yaml file as bellow:

./your_compiled_binary --rkset "gin[0].port=2008,gin[0].commonService.enabled=false"

Basic rules: 1: Using comma(,) to separate different k/v section. 2: Using [index] to access arrays in YAML file. 3: Using equal sign(=) to distinguish key and value. 4: Using dot(.) to access map in YAML file.

[Environment variable]: Override boot config value

Prefix of "RK" will be used as environment variable key. The schema follows above.

example-boot.yaml: gin:

  • port: 1949 commonService: enabled: true

We can override values in example-boot.yaml file as bellow:

os.Setenv("RK_GIN_0_PORT", "2008") os.Setenv("RK_GIN_0_COMMONSERVICE_ENABLED", "false")

./your_compiled_binary

Important! Please make sure the type of value keeps the same, otherwise, it won't override. For example, os.Setenv("RK_GIN_0_PORT", "invalid-port") won't success, but keep original value.

How to create a new custom entry? Please see example/ for details Step 1: Construct your own entry YAML struct as needed example: --- myEntry: 

enabled: true
key: value

Step 2: Create a struct which implements Entry interface

Step 3: Implements EntryRegFunc

Step 4: Register your reg function in init() in order to register your entry while application starts

How entry interact with rk-boot.Bootstrapper? 1: Entry will be created and registered into rkentry.GlobalAppCtx 2: Bootstrap will be called from Bootstrapper.Bootstrap() function 3: Application will wait for shutdown signal 4: Interrupt will be called from Bootstrapper.Interrupt() function
