Navigate to “Blob Stores” and click the “Create blob store”. The password is located at “/nexus-data/admin.password”. Copy the demo pipeline code and paste it into “Pipeline script” under configuration: This concludes our first blog in a series of posts dedicated to building a production-grade CI/CD pipeline based on open source tools. You can later use this label as ‘node selector’ in any Jenkins job to specify which worker nodes the job should run on. You can also specify the worker pod settings in the build pipeline — a preferred and more flexible approach. It covers all subdomains created for the services. Depending on your use case (dev, QA, staging, production), you’ll need different specs. This means that the external backup location (e.g. In the “advanced” section, you can customize the pods’ requests and limits. Save my name, email, and website in this browser for the next time I comment. Select the “Pipeline” type and click save. Then, run the install command specifying the official Helm chart and the newly edited file: If everything works well, you should see an output similar to this: If you haven’t created the new DNS records yet and need to find the default ingress controller URL (e.g. Automation is the key to fast development iteration, based on instant feedback and self-service dev/QA/test environments. You should see something like this with instructions on how to read the initial random password from the secret written in the bottom: Run the example command to get the password: Now run this, to get the URL for the LoadBalancer of Jenkins service: Then, go to the URL, log in as “admin” and the password you received earlier. Now, let’s create the S3 storage for all repositories. You can find them in the. Try to pull a random upstream image like “nginx” or “ubuntu.” Tag it as “docker.yourwebsite.com/some-test-name” and do a “docker push” for this new tag to push the image to a Nexus registry. When navigating for the first time to the newly created “nexus.yourwebsite.com” page and logging into the Nexus web UI (top right corner), you’ll see a quick setup wizard that will prompt you to change the temporary password. Diese kreative und agile Herangehensweise, gepaart mit Teamarbeit, Integrität sowie Spaß an interdisziplinärer und standortübergreifende Zusammenarbeit, stellt unseren anhaltenden Erfolg sicher. A Kubernetes cluster for Jenkins, Nexus, and Jenkins build workers; The Jenkins master installed on Kubernetes; The Jenkins master and Kubernetes integration to run the build workers; Docker image for the Jenkins workers. If you navigate to the Jenkins’ homepage, you’ll see the ephemeral “build executor” (aka the pod) on the list: As soon as the build is complete, It will disappear. Select the S3 store, and click “Create Repository”: Now, log into the repository with “docker login docker.yourwebsite.com -u admin”. type. We’ll use Kublr to manage our Kubernetes cluster, Jenkins, Nexus, and your cloud provider of choice or a co-located provider with bare metal servers. You’ll need to set the same CPU/Memory value for ‘requests’ and ‘limits’ in the pod definition. The UI dashboard will ask you to change the password to a permanent one. Should you need the master to be able to execute a particular job (e.g. If a VPC S3 endpoint is enabled, the S3 storage will be accessed securely by the Kubernetes EC2. This is the first in a series of tutorials on setting up a secure production-grade. Before we continue, let’s go over the most important configuration options for persistent storage, backup, and recovery: It’s also worth mentioning some important settings you may want to tweak before installing the chart. The images can’t be intercepted as they never get transferred through the public internet. Join our team! Build and deployment pipelines should be built as code in version control and automatically tested when changes are introduced into the pipeline. should be automated based on thresholds. We developed a list of tools and best practices that will allow them to iterate quickly, get instant feedback on their builds and failures, and experiment: First, we will cover the initial setup and configuration of: Assuming we have enough storage capacity, we can store the Docker images and other artifacts securely in the local cluster. Kubernetes might terminate a running pod which exceeds the limits. No need to download it. Create a Docker repository using the new Blob Store: Give it a name and select the storage type. You can find them in the “master” section of the readme: The Jenkins agent section configures the dynamic slaves that will run in the cluster. By default, they will point to the pod’s PV, which is not what we want. Even those which replicate a full stage or production environment through, if required by test results. This is the first in a series of tutorials on setting up a secure production-grade CI/CD pipeline. Here you’ll find a Helm chart for Nexus. Also, make sure to set these values to a higher number if you plan to run a massive amount of jobs at the same time. Then proceed with installing Jenkins with persistence enabled, download the values.yaml file, specify the required sections (e.g., persistence, agent and master), then run this command: helm install --name jenkins -f your_edited_values_file.yaml stable/jenkins. Before we get started with the Jenkins pipelines, we’ll create a. . The image will be uploaded to our Nexus registry and stored in the S3 bucket. All configuration options are documented, and you can tweak your installation according to your requirements. Copy the full backup from S3 (or whichever storage you used) into the mounted folder location (by default it’s/var/jenkins_home/ in the official Jenkins image). You’ll need basic Kubernetes knowledge, a test cluster (you can use an existing cluster or create a new one with a few clicks using Kublr), and a strong desire to automate everything! Knowing what is available during the build, can help you implement some flexible scripts inside the build pipeline. to work with the cluster. Auch Sie wollen mit Ihrer Fachkompetenz und Ihrer Persönlichkeit einen Unterschied im Gesundheitswesen machen? Since we named the Blob Store “primary,” that’s what we see in the selection box. Mit der weiteren Nutzung dieser Website und der Navigation auf dieser Website stimmen Sie der Verwendung von Cookies zu. You own the images and artifacts, and everything takes place inside the local network (or the local virtual network of the cloud provider like VPC in AWS, or VNET in Azure). No actions required, except for a pod failure investigation. Our goal is to make sure that our setup works and then proceed to a Nexus repository configuration. The benefits are obviously speed and security. Hier bei NEXUS entwickeln Menschen mit Leidenschaft einige der innovativsten Softwareprodukte im Gesundheitswesen. Then, select S3, set a name, and specify the bucket name to store the files. That’s particularly convenient for full scale integration tests. Damit leisten wir einen wertvollen Beitrag für die tägliche Arbeit in … When creating a template, calculate the limits carefully. Each development team has different needs, build tools and dependencies. It will also ask you whether or not to allow anonymous access to the artifacts. Additionally, it monitors metrics inspection in the same pipeline where Kubernetes clusters are created using a few lines of code to call the Kublr API. If you do run them in the cluster, you may want to put the slaves in a different namespace. It’s advisable to separate dev/QA/stage clusters. Ensure you can see the existing helm release list so you know Helm is properly configured (if you use a Kublr demo cluster, you’ll see a few default Helm releases installed): : should be set to ‘false’ to use the ingress controller TLS termination which usually has a wildcard “*.yourdomain.com” certificate. Create a new pipeline job by clicking “New Item,” and then give it a name. After setting the whitelist as shown below, try to log into the registry. Wait for the executor pod to start. We recommend using the original “values.yaml” file when installing, instead of overriding the list of plugins through “–set”. Automation is the key to fast development iteration, based on instant feedback and self-service dev/QA/test environments. Auf der Suche nach bahnbrechenden Technologien entwickeln wir uns fortlaufend weiter und werden dabei durch Vorschläge sowie Impulse unserer Mitarbeiter unterstützt. It will be a quick demo since we’ll provide an in-depth tutorial for production CI/CD on Kubernetes in the next post. A common goal of SRE and DevOps practitioners is to enable development and QA teams. But for now, let’s install our local Nexus repository, to be able to store the Docker images and other build dependencies locally in the cluster. Otherwise, they will start in the “default” namespace. You’ll need basic Kubernetes knowledge, a test cluster (you can use an existing cluster or, create a new one with a few clicks using Kublr. Here’s an example of how to whitelist the custom registry for this Docker type. Don’t upload artifacts to the pod’s physical volume. Our goal is to make sure that our setup works and then proceed to a Nexus repository configuration. We will, however, configure it using an existing well-designed and polished Helm chart from a stable repository. If a high error rate is detected (or “higher than usual,” in the case of a hotfix release for a partially unstable production service which already had some errors or warnings in its log), the deployment can be rolled back, to keep all Docker images deployed in the Kubernetes cluster (it can be. If the Kubernetes cluster nodes aren’t on AWS or don’t have IAM Roles assigned (IAM roles that allows access to the S3 bucket), provide your AWS access keys. After a few minutes, when the DNS records propagate, you can navigate to the Nexus UI dashboard in the browser to configure the Docker registry.
