OpenShift Pipelines is based on the Tekton project, and offers a native integration with the OpenShift platform to provide a smooth experience for the developers. Basically, the main concepts are as follows, split into concepts that define the pipeline and others that run the pipeline. Builds that use Red Hat Satellite to install content must provide appropriate configurations to obtain content from openshift consulting Satellite repositories. Use the following sections to run entitled builds on OpenShift Container Platform. You can cancel all builds in a given state, such as new or pending, while ignoring the builds in other states. The jenkinsfile is run on the Jenkins agent pod, which must have the OpenShift Container Platform client binaries available if you intend to use the OpenShift Container Platform DSL.
The corresponding value of BuildConfig.spec.source.type is Binary for these builds. The set of Transport Layer Security (TLS) certificate authorities (CA) that are trusted during a Git clone operation are built into the OpenShift Container Platform infrastructure images. If your Git server uses a self-signed certificate or one signed by an authority not trusted by the image, you can create a secret that contains the certificate or disable TLS verification. If your cluster uses an ImageContentSourcePolicy object to configure repository mirroring, you can use only global pull secrets for mirrored registries. The arguments are the same as the previous example with the addition of a header
and a payload. The -H argument sets the Content-Type header to
application/yaml or application/json depending on your payload format.
This behavior allows for, among other uses, the installation and usage of test dependencies that are automatically discarded and will be not present in the final image. A configuration change trigger allows a build to be automatically invoked as soon as a new BuildConfig is created. The former is to make the webhook URL unique and hard to predict, the latter is an optional string field used to create HMAC hex digest of the body, which is sent as an X-Hub-Signatureheader. Note that the value of the secret is base64 encoded as is required for any data field of a Secret object. Webhook triggers allow you to trigger a new build by sending a request to the OpenShift Container Platform API endpoint.
- The resourceVersion value in a secret is not specified when it is referenced.
- When using an image change trigger for the strategy image stream, the generated
build is supplied with an immutable Docker tag that points to the latest image
corresponding to that tag.
- Oc new-app and oc new-build will create GitHub and Generic webhook triggers automatically, but any other needed webhook triggers must be added manually (see Setting Triggers).

External artifacts can be used to pull in additional files that are not available as one of the other build input types. In addition to setting the image field for all Strategy types, for custom
builds, the OPENSHIFT_CUSTOM_BUILD_BASE_IMAGE environment variable is checked. If
it does exist then it is updated with the immutable image reference. Image change triggers allow your build to be automatically invoked when a new
version of an upstream image is available. For example, if a build is based on
top of a RHEL image, then you can trigger that build to run any time the RHEL
image changes. As a result, the application image is always running on the
latest RHEL base image.
3.8. Using docker credentials for private registries
All forms in the following examples are equivalent and execute bundle exec rake test –verbose. Apparently, bitbucket and elastic search have a problem to deal with the glusterfs storage file system. Note that this won’t actually build our application yet, it just does a simple echo and listing of the directory. Now that we have BitBucket https://www.globalcloudteam.com/ with a code repo sitting pretty, we can connect it to Bamboo and then proceed to some other configuration such as a Kubernetes remote agent. This is actually decently straight-forward to get installed, slightly confusing to get the trial license for – especially since their site tries to push everyone to their weird cloud service.
You use its name and namespace to identify the image change trigger in buildConfig.spec.triggers that triggered the build. After the Jenkins job’s initial creation, you can still add additional parameters to the job from the Jenkins console. The parameter names differ from the names of the environment variables in the build configuration. The parameters are honored when builds are started for those Jenkins jobs. Pipelines give you control over building, deploying, and promoting your applications on OpenShift Container Platform. The environment variables defined there are passed to the pod that runs the custom build.

For other image change triggers that do not reference the strategy image stream, a new build is started, but the build strategy is not updated with a unique image reference. You can use image change triggers to automatically invoke your build when a new version of an upstream image is available. For example, if a build is based on a RHEL image, you can trigger that build to run any time the RHEL image changes. As a result, the application image is always running on the latest RHEL base image. For other image change triggers that do not reference the strategy image stream,
a new build will be started, but the build strategy will not be updated with a
unique image reference. In addition to setting the image field for all Strategy types, for custom builds, the OPENSHIFT_CUSTOM_BUILD_BASE_IMAGE environment variable is checked.
Imagestreams that point to container images in v1 container registries only trigger a build once when the imagestreamtag becomes available and not on subsequent image updates. When defining the trigger, you must specify a secret, which will be part of the URL you supply to GitHub when configuring the webhook. Service serving certificate secrets are intended to support complex middleware applications that need out-of-the-box certificates. It has the same settings as the server certificates generated by the administrator tooling for nodes and masters. You can make key values from secrets available as environment variables using the valueFrom syntax. If a pull secret for the registry exists in both the namespace and the node, builds default to using the pull secret in the namespace.
Source Clone Secrets
For more information about communicating with a Git repository using these protocols see the hosted version of the Pro Git book. The application is successfully deployed to the OpenShift cluster. Before creating the link for the repository, you should give an approval for the link. We have successfully created the link between Bamboo and Bitbucket. With help of this link, Bamboo will easily fetch the code that is stored in Bitbucket.
The main posts used GitHub as the hosting service, but we also summarised key details when using GitLab and Bitbucket in subsequent posts. The first build takes the application source and produces an image containing a WAR file. The path of the output artifact depends on the assemble script of the S2I builder used. In this case, it is output to /wildfly/standalone/deployments/ROOT.war. The lastTriggerTime with the most recent timestamp signifies the ImageChangeTriggerStatus of the last build. This ImageChangeTriggerStatus has the same name and namespace as the image change trigger in buildConfig.spec.triggers that triggered the build.
7.2. Canceling a build
You can inject information about the build object by setting the fieldPath environment variable source to the JsonPath of the field from which you are interested in obtaining the value. For the OpenShift Container Platform container image registry, this is not required because secrets are generated automatically for you by OpenShift Container Platform. The value in the type field indicates the structure of the secret’s key names and values.
The current working directory is set to the image’s WORKDIR, which is the default working directory of the container image. Currently, OpenShift Container Platform webhooks only support the analogous versions of the push event for each of the Git-based source code management systems (SCMs). Therefore, a secret needs to be created before any pods that depend on it. The most effective way to ensure this is to have it get injected automatically through the use of a service account. Users normally remove their input secrets from the final application image so that the secrets are not present in the container running from that image. However, the secrets still exist in the image itself in the layer where they were added.
In this step, we will create a SSH key pair to enable access to Bitbucket Server. Bamboo also uses SSH key to fetch the code but it created its own SSH key in the previous step to access Bitbucket. After solving the certificate problem with Docker, push an arbitrary image to the repository to test it. OpenShift includes other software such as application runtimes as well as infrastructure components from the Kubernetes ecosystem.
