Deploying and Monitoring Applications with Jenkins

Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

In this challenge, you will verify that Jenkins, Prometheus, Grafana, and Nagios containers are running without errors. Additionally, you will check that Docker, Git, and Terraform are installed in the lab environment. Finally, you will navigate to the lab files directory to confirm that all necessary files are present.

In this challenge, you will be taught how to verify access to the Jenkins UI using the provided credentials, install the required plugins, configure the installed plugins, and create the necessary variables that would be used within our pipeline jobs.

In this challenge, you will set up Prometheus to collect data from Jenkins, configure Grafana to create a Jenkins dashboard using Prometheus as a data source, and use Nagios to monitor infrastructure and container health.

In this challenge, you will create a Jenkins pipeline job to deploy a simple web application. You will configure SSH-Agent credentials to enable Jenkins to access the Git server and set up the pipeline to poll for changes and trigger deployments automatically. Additionally, you will also configure post-deployment monitoring using the Jenkins Dashboard, which will populate Prometheus and Grafana with deployment metrics.

In this challenge, you will modify an existing Jenkins pipeline job to implement a Blue/Green deployment strategy. Then, you will confirm that monitoring tools (Grafana & Prometheus) are capturing deployment performance metrics.

Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
