y2hcl

a CLI Tool to convert Yaml values file (e.g. Helm Chart Values) to the following format:

• Helm cli set values, e.g. --set some.var="somevalue"
• Terraform helm_release provider set_value
• Terraform helm_release provider sensitive_value
• HCL variable of type map, e.g. some_map = {"some.var" = "somevalue"}

Installation

You can install this using the cargo install command:

$ cargo install y2hcl

Usage

$ y2hcl --help

Convert Helm Chart Values yaml to Terraform helm_release set_value, Helm Cli --set values etc.

Usage: y2hcl --filename <FILENAME> --output-format <OUTPUT_FORMAT>

Options:
  -f, --filename <FILENAME>            Filename or full path to YAML formated Helm Chart values
  -o, --output-format <OUTPUT_FORMAT>  Output format is how we want our Helm Chart values to look like. Supported format are `hcl_map`, `set_value`, `sensitive_value`, `helm_cli`
  -h, --help                           Print help
  -V, --version                        Print version

Examples

For example, a file values.yaml contains the following:

livenessProbe:
  httpGet:
    path: /user/login
    port: http
  initialDelaySeconds: 120

1. YAML values to HCL Map

$ y2hcl -f values.yaml -o hcl_map

hcl_map = {
  "livenessProbe.httpGet.path" = "/user/login"
  "livenessProbe.httpGet.port" = "http"
  "livenessProbe.initialDelaySeconds" = "120"
}

2. YAML values to helm_release set_value

$ y2hcl -f values.yaml -o set_value


    set_value = {
      name = "livenessProbe.httpGet.path"
      value = "/user/login"
    }

    set_value = {
      name = "livenessProbe.httpGet.port"
      value = "http"
    }

    set_value = {
      name = "livenessProbe.initialDelaySeconds"
      value = "120"
    }

3. YAML values to helm_release sensitive_value

$ y2hcl -f values.yaml -o sensitive_value


    sensitive_value = {
      name = "livenessProbe.httpGet.path"
      value = "/user/login"
    }

    sensitive_value = {
      name = "livenessProbe.httpGet.port"
      value = "http"
    }

    sensitive_value = {
      name = "livenessProbe.initialDelaySeconds"
      value = "120"
    }

4. YAML values to Helm CLI set values

$  y2hcl -f values.yaml -o helm_cli


--set livenessProbe.httpGet.path="/user/login" \
--set livenessProbe.httpGet.port="http" \
--set livenessProbe.initialDelaySeconds="120" \
