Helm Chart Template

# New Template

Visit Assets → Templates → Helm Chart in sequence, click the + button, enter the Helm Chart template name in the pop-up modal box, and import the template content from the code repository.

# Variable List

After the template content is saved successfully, the system will automatically parse the variables used in the values.yaml of the template.

• System Built-in Variables: Includes $T-Project$ and $T-Service$, which can be used directly in the Helm Chart template. After creating a new service based on the template in the project, these will be automatically replaced with the corresponding project name and service name.
• Custom Variables: Define and use in the template using the format {{.key}}. You can assign a default value. When creating a new service based on the template in the project, you can modify the value of the custom variable to redefine the service.

# Apply to Service

Click Apply to Service to update all service configurations with Automatic Synchronization enabled using the latest template content.

Turn on the Automatic Synchronization operation for the service. Refer to the use template to create a new service. :::

# Using Templates

When creating a new service in the K8s Helm Chart project, you can choose to import services from templates, and refer to using templates to create a new service.

# Helm Chart Template Example

A Helm Chart template is also a complete Helm Chart in terms of structure, as shown below:

path/to/your/helm-chart
├── Chart.yaml # The Chart.yaml file is required for the chart
├── templates # The template directory in the chart, a series of Kubernetes YAML files
│   ├── deployment.yaml
│   ├── service.yaml
│   └── .....
└── values.yaml # The default configuration values for the chart
