Serialization Template Tool (STT)

As a YAML Template Tool

Helm is a great way to organize your application, but when dealing with multiple regions or chart templates, stt simplifies the process of generating/modifying values using templates and values.

go run main.go -t example/temp -o example/output -v example/values.yaml

Different delimiter

go run main.go -t example/temp -o example/output -v example/values.yaml -d "[[,]]"

Example

-t example/temp/example_yaml.yaml

templatelist:
{{- range .list }}
  - name: "{{.name}}"
    age: {{.age}}
    city: "{{.city}}"
    status: {{if ge .age 30}}Senior Citizen{{else}}Youngster{{end}}
{{- end }}

-v example/values.yaml

name: John Doe
age: 30
email: john.doe@example.com

list:
  - name: Alice
    age: 25
    city: New York
  - name: Bob
    age: 30
    city: London
  - name: Carol
    age: 28
    city: Paris

-o example/output

This will generate/overwrite files in the example/output directory.

templatelist:
  - name: "Alice"
    age: 25
    city: "New York"
    status: Youngster
  - name: "Bob"
    age: 30
    city: "London"
    status: Senior Citizen
  - name: "Carol"
    age: 28
    city: "Paris"
    status: Youngster

option

  -d string
        delimiter, like "[[,]]" (default "{{,}}")
  -o string
        Output Directory path, only [Dir]
  -t string
        Template file or directory path
  -v string
        Values file

Todo:

• Implement JSON template tool

• YAML <-> JSON conversion

• Read from JSON

• Check the validity of the value file and output file

• Map for template to output, also support multi-input/output
