The Muti-Cloud Test (MCT) code repository contains a set of Terraform deployment scripts that can be used in a DevOps pipeline to establish two parallel multi-cloud test labs. This facilitates the set up, testing, and destruction of complete virtual environments. Each network security test lab environment incorporates three public cloud projects: Amazon AWS, Microsoft Azure, and Google Cloud Platform (GCP). A pair of external “Admin” virtual machines is used for running the setup and test scripts. This approach allows rapid iteration of the setup and testing steps using virtual machines and Kubernetes clusters with matching application services, network connections, and user access controls.

Jenkins is an open source, Java-based automation server that offers an easy way to set up a continuous integration and continuous delivery (CI/CD) pipeline. Continuous integration (CI) is a DevOps practice in which team members regularly commits their code changes to the version control repository, after which automated builds and tests are run. Continuous delivery (CD) is a series of practices where code changes are automatically built, tested and deployed to production. This tutorial will walk you through the steps of installing Jenkins on a CentOS 7 system using the official Jenkins repository. Prerequisites Before continuing with this tutorial, make sure you are logged in as a user with sudo privileges. Installing Jenkins To install Jenkins on your CentOS system, follow the steps below: Jenkins is a Java application, so the first step is to install Java. Run the following command to install the OpenJDK 8 package: sudo yum install java-1.8.0-openjdk-devel Copy The current version of Jenkins does not support Java 10 (and Java 11) yet. If you have multiple versions of Java installed on your machine make sure Java 8 is the default Java version. The next step is to enable the Jenkins repository. To do that, import the GPG key using the following curl command: curl --silent --location http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo | sudo tee /etc/yum.repos.d/jenkins.repo Copy And add the repository to your system with: sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key Copy Once the repository is enabled, install the latest stable version of Jenkins by typing: sudo yum install jenkins Copy After the installation process is completed, start the Jenkins service with: sudo systemctl start jenkins Copy To check whether it started successfully run: systemctl status jenkins Copy You should see something similar to this: ● jenkins.service - LSB: Jenkins Automation Server Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled) Active: active (running) since Thu 2018-09-20 14:58:21 UTC; 15s ago Docs: man:systemd-sysv-generator(8) Process: 2367 ExecStart=/etc/rc.d/init.d/jenkins start (code=exited, status=0/SUCCESS) CGroup: /system.slice/jenkins.service Copy Finally enable the Jenkins service to start on system boot. sudo systemctl enable jenkins Copy jenkins.service is not a native service, redirecting to /sbin/chkconfig. Executing /sbin/chkconfig jenkins on Copy Adjust the Firewall If you are installing Jenkins on a remote CentOS server that is protected by a firewall you need to port 8080. Use the following commands to open the necessary port: sudo firewall-cmd --permanent --zone=public --add-port=8080/tcp sudo firewall-cmd --reload Copy Setting Up Jenkins To setup your new Jenkins installation, open your browser and type your domain or IP address followed by port 8080: http://your_ip_or_domain:8080 Copy A screen similar to the following will appear, prompting you to enter the Administrator password that is created during the installation: Use the following command to print the password on your terminal: sudo cat /var/lib/jenkins/secrets/initialAdminPassword Copy You should see a 32-character long alphanumeric password as shown below: 2115173b548f4e99a203ee99a8732a32 Copy Copy the password from your terminal, paste it into the Administrator password field and click Continue. On the next screen you will be asked whether you want to install the suggested plugins or to select specific plugins. Click on the Install suggested plugins box, and the installation process will start immediately. Once the installation is complete, you will be prompted to set up the first administrative user. Fill out all required information and click Save and Continue. On the next page you will be asked to set the URL for the Jenkins instance. The URL filed will be populated with an automatically generated URL. To complete the setup confirm the URL by clicking on the Save and Finish button. Finally, click on the Start using Jenkins button and you will be redirected to the Jenkins dashboard logged in as the admin user you have created in one of the previous steps. If you’ve reached this point, you’ve successfully installed Jenkins on your CentOS system. Conclusion In this tutorial, you have learned how to install and complete the initial configuration of Jenkins on CentOS/RHEL based systems. You can now visit the official Jenkins documentation page and start exploring Jenkins’s workflow and plug-in model.

A repository containing all you need to get setup for Azure DevOps Agents in Virtual Machine Scale Sets

Amazon DevOps Guru is a machine learning (ML) powered service that gives you a simpler way to improve an application’s availability and reduce expensive downtime. Without involving any complex configuration setup, DevOps Guru automatically ingests operational data in your AWS cloud. When DevOps Guru identifies a critical issue, it automatically alerts you with a summary of related anomalies, the likely root cause, and context on when and where the issue occurred. DevOps Guru also, when possible, provides prescriptive recommendations on how to remediate the issue. Amazon DevOps Guru also integrates with Amazon EventBridge to notify you of events relating to insights and corresponding insight updates. DevOps Guru generates insights when it detects anomalous behavior in your operational applications and can alert you of a potential issue in near real-time when you set up notifications. With this integration, you can set up routing rules to determine where to send notifications, use pre-defined DevOps Guru patterns to only send notifications or trigger actions that match that pattern (e.g., only send for “New Insights Open”), or create custom patterns to send notifications. For example, you may only want to be notified when a new insight is opened that DevOps Guru has marked as high severity which could then trigger an action that sends it to a specific ticketing queue so you can immediately address the issue.
