What tools did you use for automating the build and deployment of the application?

The following tools are often used for automating the build and deployment of applications:

• Jenkins — a popular automation server with support for numerous plugins.
• GitLab CI/CD — an integrated pipeline tool within GitLab.
• Travis CI — a cloud service for automatic building and testing.
• Docker — for containerizing applications, simplifying deployment.
• Ansible, Chef, Puppet — tools for automating configuration and deployment.
• Kubernetes — for orchestrating containers in production.

Example of a simple Jenkins pipeline for build and deploy:

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                sh 'go build -o myapp'
            }
        }
        stage('Deploy') {
            steps {
                sh './deploy.sh'
            }
        }
    }
}

The choice of tools depends on the project requirements and infrastructure.
