Deployment Strategies in TuskLang for Go

Overview

Deployment strategies in TuskLang provide powerful deployment configuration and automation capabilities directly in your configuration files. These features enable you to define sophisticated deployment strategies, infrastructure management, and deployment workflows with Go integration for production-ready applications.

GitOps Deployment

deployment: {
    gitops: {
        enabled: true
        repository: "@env('GITOPS_REPO')"
        branch: "main"
        path: "manifests"
        
        sync: {
            enabled: true
            interval: "5m"
            prune: true

Performance Considerations

- Deployment Speed: Optimize deployment processes for faster delivery - Resource Management: Efficiently manage deployment resources - Rollback Speed: Ensure fast rollback capabilities - Monitoring Overhead: Minimize monitoring overhead during deployments - Network Efficiency: Optimize network usage during deployments

Security Notes

- Secrets Management: Secure deployment secrets and credentials - Access Control: Implement proper access control for deployment systems - Audit Logging: Log all deployment activities for security auditing - Image Security: Scan container images for vulnerabilities - Network Security: Secure deployment network communications

Best Practices

1. Automated Testing: Include comprehensive testing in deployment pipelines 2. Gradual Rollout: Use gradual rollout strategies for safer deployments 3. Monitoring: Monitor deployments and application health 4. Documentation: Document deployment procedures and configurations 5. Backup Strategy: Implement proper backup and recovery procedures 6. Compliance: Ensure deployments meet compliance requirements

Integration Examples

With Kubernetes

import (
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/rest"
    "github.com/tusklang/go-sdk"
)

func setupKubernetes(config tusk.Config) *kubernetes.Clientset { var deploymentConfig DeploymentConfig config.Get("deployment", &deploymentConfig) if !deploymentConfig.Infrastructure.Kubernetes.Enabled { return nil } k8sConfig, err := rest.InClusterConfig() if err != nil { log.Fatalf("Error getting Kubernetes config: %v", err) } client, err := kubernetes.NewForConfig(k8sConfig) if err != nil { log.Fatalf("Error creating Kubernetes client: %v", err) } return client }

With Docker

import (
    "github.com/docker/docker/client"
    "github.com/tusklang/go-sdk"
)

func setupDocker(config tusk.Config) *client.Client { var deploymentConfig DeploymentConfig config.Get("deployment", &deploymentConfig) if !deploymentConfig.Infrastructure.Docker.Enabled { return nil } cli, err := client.NewClientWithOpts(client.FromEnv) if err != nil { log.Fatalf("Error creating Docker client: %v", err) } return cli }
