First watch if the Jenkins agent pods are started. Please refer to the section below. here. It can be customized using a system property. Select the project that you want to use. Otherwise, any attempts to access these VMs are denied. gcloud --project my_project compute ssh my_vm. At the moment the jenkinsci agent image is not built for OpenShift and will issue this warning. however once again, you will need to express the specific container you wish to execute commands in. Docker image - the docker image name that will be used as a reference to spin up a new Jenkins agent, as seen below. node('some-label') uses a label declared by a pod template, the Kubernetes Cloud allocates a new pod to run the For more detail, configure a new Jenkins log recorder for from jenkinsci/dependabot/maven/org.jenkins-, Restricting what jobs can use your configured cloud. Service account and Node selector when are overridden completely substitute any possible value found on the 'parent'. See Defining a liveness command for more details. If nothing happens, download GitHub Desktop and try again. It is created while the pipeline execution is within the In the example below, we will inherit from a pod template we created previously, and will just override the version of Jenkins plugin to run dynamic agents in a Kubernetes cluster. It should be noted that the main reason to use the global pod template definition is to migrate a huge corpus of WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. To set a constraint for external IP access, you first need your organization ID. In any case if the referenced template is not found it will be ignored. Optional: In the Service account description field, enter a description.. Click Create.. Click the Select a role field. This variable only applies to your Get the ip (in this case 104.197.19.100) with kubectl describe services/jenkins We do not recommend overriding the jnlp container except under unusual circumstances. adequate communication from Jenkins to the Kubernetes cluster, as seen below, In addition to that, in the Kubernetes Pod Template section, we need to configure the image that will be used to gcloud config set project
For a detailed account of these concepts, see the Configurations guide. New customers also get $300 in free credits to run, test, and deploy workloads. For production use, such as an application running on Compute Engine, you would use a service account to represent Such pod templates are not intended to be shared with other The command stores the service account's allow policy in a policy.json file. See here for more information. but can greatly simplify setup when agents are in an external cluster Based on the official image. Ports in each container can Replace ACCOUNT with your service account email address and KEY-FILE with the filename for your service account key. and using a service account to authenticate to Kubernetes API. If you see the agents happen to connect to the wrong host, see you can use ['\$(JENKINS_SECRET)', '\$(JENKINS_NAME)'], ln -s `pwd` /go/src/github.com/hashicorp/terraform, cd /go/src/github.com/hashicorp/terraform && make, sh: can't create /home/jenkins/agent/workspace/thejob@tmp/durable-e0b7cd27/jenkins-log.txt: Permission denied, sh: can't create /home/jenkins/agent/workspace/thejob@tmp/durable-e0b7cd27/jenkins-result.txt.tmp: Permission denied, mv: can't rename '/home/jenkins/agent/workspace/thejob@tmp/durable-e0b7cd27/jenkins-result.txt.tmp': No such file or directory, touch: /home/jenkins/agent/workspace/thejob@tmp/durable-e0b7cd27/jenkins-log.txt: Permission denied. does not have a public hostname for the VM to access, you can set the jenkins.host.address There was a problem preparing your codespace, please try again. The following idiom creates a pod template with a generated unique label (available as POD_LABEL) and runs commands inside it. Other containers can run arbitrary processes of your choosing, To enable this, in your cloud's advanced configuration check the Kubernetes Pod Template Name - can be any and will be shown as a prefix for unique generated agent names, which will to be accessible from the kubernetes cluster. This can be done checking Enable proxy compatibility under Manage Jenkins -> Configure Global Security. To open the Overview page of an instance, click the instance name. After you create an account, you grant the account IAM roles and set up instances to run as the service account. Learn how to set up a Media CDN, for planet-scale media delivery . WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. Fill in the Kubernetes plugin configuration. Note: If you want to identify a service account just after it is created, use the numeric ID rather than the email address to ensure that it is reliably identified. podTemplate block. Commands will be executed by default in the jnlp container, where the Jenkins agent is running. This feature is extra useful, pipeline library developers as it allows you to wrap pod templates into functions and let By default Jenkins will listen on 192.168.64.1 interface only, for security reasons. WebIf Prometheus is running within GCE, the service account associated with the instance it is running on should have at least read-only permissions to the compute resources. and will be the container acting as Jenkins agent. jenkins.host.address as mentioned above. Select 'Certificate' as credentials type if the In many cases it would gcloud compute If no matching container template is found, the template is added as is. Enable OS use this cloud configuration you will need to add it in the jobs folder's configuration. A tag already exists with the provided branch name. and note the admin password and server certificate. Run the Pipeline or individual stage within a custom workspace - not required unless explicitly stated. Data import service for scheduling and moving data into BigQuery. You need to explicitly declare the inheritance if necessary using the field inheritFrom. Click Done to finish creating the service account. WebThere are several ways Velero can authenticate to Azure: (1) by using a Velero-specific service principal; (2) by using AAD Pod Identity; or (3) by using a storage account access key. If you're new to Google Cloud, create an account to evaluate how Compute Engine performs in real-world scenarios. If you plan to use Velero to take Azure snapshots of your persistent volume managed disks, you must use the service principal or AAD Pod Identity method. Select a project, folder, or organization. node, as shown in this example: In scripted pipelines, there are cases where this implicit inheritance via nested declaration is not wanted or another For that some environment variables are automatically injected: Tested with jenkins/inbound-agent, gcloud . To set up a service account, you configure the receiving service to accept requests from the calling service by making the calling service's service account a principal on the receiving service. explicit inheritance is preferred. Change the Service account ID to a unique, recognizable value and then click Create and continue. The Google Cloud console lists all the principals who have been granted roles on your project, folder, or In the Google Cloud console, go to the Create service account page.. Go to the Create Service Account page. If you check WebSocket then agents will connect over HTTP(S) rather than the Jenkins service TCP port. The FIREBASE_CONFIG environment variable is included automatically in Cloud Functions for the VM, then run the following command, using the service account # that gcloud returned when you checked the scopes. Jenkins agent. Cloud Storage is a service for storing objects in Google Cloud. In the following examples, you WebContainer Registry is a single place for your team to manage Docker images, perform vulnerability analysis, and decide who can access what with fine-grained access control. If they are in a different state than Running, use describe to get the events, If they are Running, use logs to get the log output. Instead, service accounts use RSA key pairs for authentication: If you know the private key of a service account's key pair, you can use the private key to create a JWT bearer token and use the bearer token to request an access token. needs to be configured to avoid WARNING: No valid crumb was included in request errors. Positional arguments and options Client libraries make it easier to access Google Cloud APIs using a supported language. You can use Google Cloud APIs directly by making raw requests to the server, but client libraries provide simplifications that significantly reduce In the later case each template will This assumes that from a pod, the host system is accessible as IP address 10.1.1.1. Creating all the elements and setting the default namespace, Connect to the ip of the network load balancer created by Kubernetes, port 80. The gcloud CLI provides a set of gcloud CLI options that govern the behavior of commands on a per-invocation level. Field inheritFrom may refer a single podTemplate or multiple separated by space. Apps running on instances with the service account attached can use the account's credentials to make requests to other Google APIs. Under All When you run the installer, it downloads Google Cloud CLI components and installs them on the local system. Please note that the system you run mvn on needs to be reachable from the cluster. To create the service account, run the gcloud iam service If running outside of GCE make sure to create an appropriate service account and place the credential file in one of the expected locations. To debug this you need to set -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.LAUNCH_DIAGNOSTICS=true system property This page describes how you can use client libraries and Application Default Credentials to access Google APIs. Assuming you created a Kubernetes cluster named jenkins this is how to run both Jenkins and agents there. If nothing happens, download Xcode and try again. For integration tests install and start minikube. Pod templates defined using the user interface declare a label. The plugin creates a Kubernetes Pod for each agent started, and stops it after each build. When you set OS Login metadata, OS Login is enabled immediately. Are you sure you want to create this branch? Service account and Node selector when are overridden completely substitute any possible value found on the 'parent'. Multiple containers can be defined for the agent pod, with shared resources, like mounts. Existing CI/CD integrations let you set up fully automated Docker pipelines to Clouds can be configured to only allow certain jobs to use them. for the template. If any other properties are set outside the YAML, they will take precedence. 2-step verification is not enforced on service account users. It might be some variant such as 10.1.37.1, Provide the following values: KEY_ID: The ID of the public key you want to get. Other containers must run a long running process, so the container does not exit. In the Add a user account to instance instance_name page, you can choose whether the user WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. OpenShift runs containers using a random UID that is overriding what is specified in Docker images. ), The default jnlp agent image used can be customized by adding it to the template. yaml is merged according to the value of yamlMergeStrategy. WebOAuth2. In the Service account name field, enter a descriptive name for the service account. Make sure you are in the correct cluster and namespace. on virtualbox) and the host running mvn yaml is merged according to the value of yamlMergeStrategy. Steps will be nested within an implicit container(name) {} block instead gcloud container clusters get-credentials CLUSTER_NAME; Replace the CLUSTER_NAME with the name of your cluster. When using the WebSocket mode, the -disableHttpsCertValidation on the jenkins/inbound-agent becomes unavailable, as well as -cert, and that's why you have to extend the docker image. with the same name) in the 'parent' template, will inherit the configuration of the parent containerTemplate. In the Google Cloud console, go to the IAM page.. Go to IAM. Console Note: The Google Cloud console shows access in a list form, rather than directly showing the resource's allow policy. Data import service for scheduling and moving data into BigQuery. maven so that it uses jdk-11 instead: Note that we only need to specify the things that are different. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Optional: In the Service account users role field, add members that can impersonate the service account. WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. Run steps within a container by default. existing projects (including freestyle) to run on Kubernetes without changing job definitions. This can be done with the containerLog step, which prints the log of the Create a service account with the roles your application needs, and a key for that service account, by following the instructions in Creating a service account key. When a freestyle job or a pipeline job using This means that the pod template will inherit node selector, service account, image pull secrets, container templates If you don't mind others in your network being able to use your test jenkins you could just use this: Then your test jenkins will listen on all ip addresses so that the build pods will be able to connect from the pods in your minikube VM to your host. It is not required to run the Jenkins controller inside Kubernetes. Based on the Scaling Docker with Kubernetes article, Creating service accounts and keys. The basics of Google's OAuth2 implementation is explained on Google Authorization and Authentication documentation.. To get agents working for Openshift 3, add this Node Selector to your Pod Templates: You can run pods on Windows if your cluster has Windows nodes. (e.g. Click the Select a role field and select one of the following roles: Cloud SQL > Cloud SQL Client; Cloud SQL > Cloud and the Jenkins controller is not directly accessible (for example, it is behind a reverse proxy or a ingress resource). gcloud auth activate-service-account ACCOUNT \ --key-file=KEY-FILE; Note: If your Jenkins controller is outside the cluster and uses a self-signed HTTPS certificate, WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. However, this approach is often too coarse. See JEP-222 for more. Options override values set in gcloud CLI properties. They can be configured via the user interface or in a pipeline and allow you to set the following fields: By default, the agent connection timeout is set to 1000 seconds. In order to do that, you will open the Jenkins UI and navigate to Manage Jenkins -> Manage Nodes and Clouds -> Configure Clouds -> Add a new cloud -> Kubernetes and enter the Kubernetes URL and Jenkins URL appropriately, unless Jenkins is running in Kubernetes in which case the defaults work. Jenkins plugin to run dynamic agents in a Kubernetes/Docker environment. in which case you would need to set -DconnectorHost= -Djenkins.host.address= instead. The container step allows executing commands into each container. Click Create service account. Activate the service account that you want to use. Image Pull Secrets are combined (all secrets defined both on 'parent' and 'current' template are used). How you set up the permissions depends on whether the caller is using a service account or user credentials. Integration tests will use the currently configured context auto-detected from kube config file or service account. In order to support any possible value in Kubernetes Pod object, we can pass a yaml snippet that will be used as a base For example one could create functions for their podTemplates and import them for use. For OpenShift users, this means OpenShift Container Platform 4.x. and it is possible to run commands dynamically in any container in the agent pod. kubernetes cluster is configured to use client certificates for authentication. So, command and arguments are not specified, as to connect through the internal network. If your minikube is running in a VM (e.g. a database for your integration tests), you might want to access its log from the pipeline. Use Git or checkout with SVN using the web URL. Also see the online help and examples/containerLog.groovy. you will need some additional configuration. To do that, you can extend the jenkins/inbound-agent image and add your certificate as follows: Then, use it as the jnlp container for the pod template as usual. To inspect the json messages sent back and forth to the Kubernetes API server you can configure No command or args need to be specified. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. You may want to set Jenkins URL to the internal service IP, http://10.175.244.232 in this case, In the Service account name field, enter a Activate a service account in your gcloud session and then obtain an access token. To get the public key data for a service account key: Run the gcloud beta iam service-accounts keys get-public-key command: gcloud beta iam service-accounts keys get-public-key KEY_ID \ --iam-account=SA_NAME--output-file=FILENAME. WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. Either way it provides access to the following fields: Container templates are part of pod. In this case, use inheritFrom '' to remove any inheritance, or inheritFrom 'otherParent' to override it. This way, you can work with multiple Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON file that contains your service account key. Console . of being executed in the jnlp container. In the Service account name field, enter a name.. The installer lets you download, install, and set up the latest version of Google Cloud CLI in an interactive mode. They can be either configured via the user interface, or in a pipeline, using Declarative agents can be defined from yaml, or using yamlFile to keep the pod template in a separate KubernetesPod.yaml file. Agents are launched as inbound agents, so it is expected that the container connects automatically to the Jenkins controller. If you use the containerTemplate to run some service in the background A running Kubernetes cluster 1.14 or later. Note: When OS Login 2FA is enabled on your VM, you must have 2-step verification set up on your Google Account or domain to connect. Also, the golang container will be added as defined in the 'parent' template. Kubernetes URL to the container engine cluster endpoint or simply https://kubernetes.default.svc.cluster.local. In the The podTemplate step defines an ephemeral pod template. You can nest multiple pod templates together in order to compose a single one. Note that POD_LABEL will be the innermost generated label to get a node which has all the outer pods available on the Run mvn clean install and copy target/kubernetes.hpi to Jenkins plugins folder. ; Click Add user account.. Due to implementation constraints, there can be issues when executing commands in different containers if they run using different uids. However, if your Jenkins controller has HTTPS configured with self-signed certificate, you'll need to make sure the agent container trusts the CA. The Kubernetes plugin allocates Jenkins agents in Kubernetes pods. Unlike scripted k8s template, declarative templates do not inherit from parent template. Also, if you are using more than one project and don't want to set global project every time, you can use select project flag.. For example: to connect a virtual machine, named my_vm under a project named my_project in Google Cloud Platform: . New users setting up new Kubernetes builds should use the podTemplate step as shown in the example snippets Container templates that are added to the podTemplate, that has a matching containerTemplate (a container template Restrict pipeline support to authorized folders box. Then you grant that service account the Cloud Run Invoker (roles/run.invoker) role. just run as. Unlike normal users, service accounts do not have passwords. If you want to provide your own Docker image for the inbound agent, you must name the container jnlp so it overrides the default one. sign in Using Kubernetes Service Account will cause the plugin to use the default token mounted inside the Jenkins pod. ; Select Users from the SQL navigation menu. The example below composes two different pod templates in order to create one with maven and docker capabilities. Some integration tests run a local jenkins, so the host that runs them needs WebSave money with our transparent approach to pricing; Google Cloud's pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources. WARNING All containers you use should have the same UID of the user, also this can be achieved by setting securityContext: Using WebSockets is the easiest and recommended way to establish the connection between agents and a Jenkins controller running outside the cluster. Modify file ./src/main/kubernetes/jenkins.yml with desired limits, Note: the JVM will use the memory requests as the heap limit (-Xmx). (it may take a bit to populate), Until Kubernetes 1.4 removes the SNATing of source ips, seems that CSRF (enabled by default in Jenkins 2) builds or projects in the Jenkins instance. Also note that in declarative pipelines the yamlFile can be used (see this example). For this reason, you may end up with the following warning in your build. You can NOT omit the node statement. a new Jenkins log recorder for okhttp3 or alternatively use the Kubernetes API username and password. Note that it was previously possible to define containerTemplate but that has been deprecated in favor of the yaml format. to use Codespaces. WebThis means that the pod template will inherit node selector, service account, image pull secrets, container templates and volumes from the template it inherits from. Multiple containers can be defined in a pod. This issue can be circumvented in various ways: OpenShift 3 is based on an older version of Kubernetes, which is not anymore directly supported since Kubernetes plugin version 1.26.0. The variable POD_CONTAINER contains the name of the container in the current context. Under credentials, click Add and select Kubernetes Service Account, the podTemplate step. For Cloud Translation - Basic, you can make any request regardless of the service account's permissions. This is unnecessary when the Jenkins controller runs in the same Kubernetes cluster, Set Container Cap to a reasonable number for tests, i.e. Global options. gcloud CLI. Specifying a different default agent connection timeout, Accessing container logs from the pipeline, Features controlled using system properties, Pipeline sh step hangs when multiple containers are used, Using WebSockets with a Jenkins controller with self-signed HTTPS certificate, Modify CPUs and memory request/limits (Kubernetes Resource API), pull images from a private Docker registry. build a docker image for OpenShift in order to behave when running using an arbitrary uid. be useful to define and compose podTemplates directly in the pipeline using groovy. It is recommended to use the same uid across the different containers part of the same pod to avoid any issue. Install gke-gcloud-auth-plugin as described in Installation instructions. see the Docker image source code. be accessed as in any Kubernetes pod, by using localhost. (The jnlp name is historical and is retained for compatibility. and then restart the pipeline. When you use a service account to provide the credentials for the Cloud SQL Auth proxy, you must create it with sufficient permissions. Create a service account: In the Google Cloud console, go to the Create service account page. and volumes from the template it inherits from. This is made possible via nesting. A local testing cluster with one node can be created with minikube, You may need to set the correct permissions for host mounted volumes, Then create the Jenkins namespace, controller and Service with. If the default entrypoint or command spin up the agent pod. Support for using WebSockets with JDK 11 was added in the Remoting v4.11, so make sure your base image is new enough.
