### Features
- If WILD_CENTRAL_ENV environment variable is set to "development", the API should run in development mode.
## Patterns
### Instance-scoped Endpoints
Instance-scoped endpoints follow a consistent pattern to ensure stateless, RESTful API design. The instance name is always included in the URL path, not retrieved from session state or context.
#### Route Pattern
```go
// In handlers.go
r.HandleFunc("/api/v1/instances/{name}/utilities/dashboard/token", api.UtilitiesDashboardToken).Methods("GET")
```
#### Handler Pattern
```go
// In handlers_utilities.go
func (api *API) UtilitiesDashboardToken(w http.ResponseWriter, r *http.Request) {
// 1. Extract instance name from URL path parameters
vars := mux.Vars(r)
instanceName := vars["name"]
// 2. Validate instance exists
if err := api.instance.ValidateInstance(instanceName); err != nil {
respondError(w, http.StatusNotFound, fmt.Sprintf("Instance not found: %v", err))
return
}
// 3. Construct instance-specific paths using tools helpers
kubeconfigPath := tools.GetKubeconfigPath(api.dataDir, instanceName)
// 4. Perform instance-specific operations
token, err := utilities.GetDashboardToken(kubeconfigPath)
if err != nil {
respondError(w, http.StatusInternalServerError, "Failed to get dashboard token")
return
}
// 5. Return response
respondJSON(w, http.StatusOK, map[string]interface{}{
"success": true,
"data": token,
})
}
```
#### Key Principles
1. **Instance name in URL**: Always include instance name as a path parameter (`{name}`)
2. **Extract from mux.Vars()**: Get instance name from `mux.Vars(r)["name"]`, not from context
3. **Validate instance**: Always validate the instance exists before operations
4. **Use path helpers**: Use `tools.GetKubeconfigPath()`, `tools.GetInstanceConfigPath()`, etc. instead of inline `filepath.Join()` constructions
5. **Stateless handlers**: Handlers should not depend on session state or current context
### kubectl and talosctl Commands
When making kubectl or talosctl calls for a specific instance, always use the `tools` package helpers to set the correct context.
#### Using kubectl with Instance Kubeconfig
```go
// In utilities.go or similar
func GetDashboardToken(kubeconfigPath string) (*DashboardToken, error) {
cmd := exec.Command("kubectl", "-n", "kubernetes-dashboard", "create", "token", "dashboard-admin")
tools.WithKubeconfig(cmd, kubeconfigPath)
output, err := cmd.Output()
if err != nil {
return nil, fmt.Errorf("failed to create token: %w", err)
}
token := strings.TrimSpace(string(output))
return &DashboardToken{Token: token}, nil
}
```
#### Using talosctl with Instance Talosconfig
```go
// In cluster operations
func GetClusterHealth(talosconfigPath string, nodeIP string) error {
cmd := exec.Command("talosctl", "health", "--nodes", nodeIP)
tools.WithTalosconfig(cmd, talosconfigPath)
output, err := cmd.Output()
if err != nil {
return fmt.Errorf("failed to check health: %w", err)
}
// Process output...
return nil
}
```
#### Key Principles
1. **Use tools helpers**: Always use `tools.WithKubeconfig()` or `tools.WithTalosconfig()` instead of manually setting environment variables
2. **Get paths from tools package**: Use `tools.GetKubeconfigPath()` or `tools.GetTalosconfigPath()` to construct config paths
3. **One config per command**: Each exec.Command should have its config set via the appropriate helper
4. **Error handling**: Always check for command execution errors and provide context
