Chapter 8  Triggering and modifying builds OpenShift Container Platform 4.5 Red Hat Customer Portal

You must create the image you want to use as your custom build image. The optional jenkinsfilePath field specifies the name of the file to use, relative to the source contextDir. If contextDir is omitted, it defaults to the root of the repository. The path to the container registry credentials for running a podman push operation.

If that developer were to leave you now have the problem that your builds are linked to that developer’s account and they could revoke the access token and break the builds. The developer also puts themselves at risk, as the access token could be used to access other private repositories they have which are not related to their work at the company. The main difference between OpenShift and vanilla Kubernetes is the concept of build-related artifacts. In OpenShift, such artifacts are considered first class Kubernetes resources upon which standard Kubernetes operations can apply. For the OpenShift platform, this provides capabilities equivalent to what Jenkins can do.

3.2. Dockerfile source

Webhook triggers allow you to trigger a new build by sending a request to the
OpenShift Container Platform API endpoint. You can define these triggers using
GitHub,
GitLab,
Bitbucket,
or Generic webhooks. When setting up a repository SSH key you should not use your primary identity SSH key. This is because you should never upload its private key to a system you do not control or which can be accessed by others. Using a primary identity key carries additional risk as it is likely used for other purposes, such as gaining secure shell access over SSH to other hosts.

You can also use the BuildConfig.spec.output.imageLabels field to specify a list of custom labels that will be applied to each image built from the build configuration. The postCommit hook is not only limited to running tests, but can be used for other commands as well. Since it runs in a temporary container, changes made by the hook do not persist, meaning that running the hook cannot affect the final image. This behavior allows for, among other uses, the installation and usage of test dependencies that are automatically discarded and are not present in the final image.

1.3. Configuration change triggers

You can combine the different methods for creating source clone secrets for your specific needs, such as a SSH-based authentication secret with a .gitconfig file. To use this functionality, a secret containing the Git repository credentials must exist in the namespace in which the BuildConfig is later created. This secrets must include one or more annotations prefixed with build.openshift.io/source-secret-match-uri-. https://www.globalcloudteam.com/ The value of each of these annotations is a Uniform Resource Identifier (URI) pattern, which is defined as follows. 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. This new image reference will be used by the strategy
when it executes for the build.

  • This is done after other input sources are processed, so if the input source repository contains a Dockerfile in the root directory, it is overwritten with this content.
  • To edit your build configurations, you use the Edit BuildConfig option in the Builds view of the Developer perspective.
  • Produces output from containers running the assemble script and all encountered errors.
  • The postCommit field of a BuildConfig object runs commands inside a temporary container that is running the build output image.
  • To prevent the contents of input secrets and config maps from appearing in build output container images, use build volumes in your Docker build and source-to-image build strategies.

The maximum duration is counted from the time when a build pod gets scheduled in the system, and defines how long it can be active, including the time needed to pull the builder image. After reaching the specified timeout, the build is terminated by OpenShift Container Platform. Additionally, the custom builder allows implementing any extended build process, such as a CI/CD flow that runs unit or integration tests. Docker builds normally create a layer representing each instruction in a Dockerfile. Setting the imageOptimizationPolicy to SkipLayers merges all instructions into a single layer on top of the base image.

You can cancel all builds from the build configuration with the following CLI command. The suggested location to put the test application built by your test/run script is the test/test-app directory in your image repository. S2I generates a Dockerfile with the builder image as the first FROM instruction. The complete list of supported environment variables is available in the using images section for each image.

The –data-binary argument is used to send a binary payload with newlines
intact with the POST request. The secret used in the webhook trigger configuration is not the same as secret
field you encounter when configuring webhook in GitHub UI. The former is to make
the webhook openshift consulting 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-Signature
header. Note that the value of the secret is base64 encoded as
is required for any data field of a Secret object.

Creating your account and repository on Bitbucket

In the popup window, give the key a name and paste in the contents of the public key file from the SSH key pair. This is the file with the .pub extension, which in our case is called repo-at-bitbucket.pub. On Bitbucket the repository SSH key is referred to by the term Access key. Search down the settings page and find the Access keys section and select it. The first step to using a private Git repository on Bitbucket using a repository SSH key is to generate the SSH key pair to be used with that repository.

Source clone secrets are used to provide the builder pod with access it would not normally have access to, such as private repositories or repositories with self-signed or untrusted SSL certificates. When you supply a dockerfile value, the content of this field is written to disk as a file named dockerfile. This is done after other input sources are processed, so if the input source repository contains a Dockerfile in the root directory, it is overwritten with this content. OpenShift Container Platform webhooks currently only support their analogous versions of the push event for each of the Git based source code management
systems (SCMs).

Configuration Change Triggers

After pushing the example project, you will see the project under the repository. We configured Nginx with a self-signed TLS certificate to make JFrog Container Registry secure. Now, open your favourite browser and gain access to the JFrog Artifactory’s dashboard. DevOps encourages collaboration, cooperation, and communication between developers and operations teams to improve the speed and quality of software development. One of the key principles of DevOps is automation, which reduces human error, provides consistent results, and even mitigates risks. With the help of automation, you and your team can build, test, and deploy software quickly and efficiently.

The build run policy describes the order in which the builds created from the build configuration should run. This can be done by changing the value of the runPolicy field in the spec section of the Build specification. Builds can be targeted to run on specific nodes by specifying labels in the nodeSelector field of a build configuration. The nodeSelector value is a set of key-value pairs that are matched to Node labels when scheduling the build pod.
