Chapter 1. Running Builds After installing Builds, you can create a buildah or source-to-image build for use. You can also delete custom resources that are not required for a build. 1.1. Creating a buildah build You can create a buildah build and push the created image to the target registry. Prerequisites You have installed the Builds for Red Hat OpenShift Operator on the OpenShift Container Platform cluster. You have created a ShipwrightBuild resource. You have installed the oc CLI. Optional: You have installed the shp CLI . Procedure Create a Build resource and apply it to the OpenShift Container Platform cluster by using one of the CLIs: Example: Using oc CLI USD oc apply -f - <<EOF apiVersion: shipwright.io/v1beta1 kind: Build metadata: name: buildah-golang-build spec: source: 1 type: Git git: url: https://github.com/shipwright-io/sample-go contextDir: docker-build strategy: 2 name: buildah kind: ClusterBuildStrategy paramValues: 3 - name: dockerfile value: Dockerfile output: 4 image: image-registry.openshift-image-registry.svc:5000/buildah-example/sample-go-app EOF 1 The location where the source code is placed. 2 The build strategy that you use to build the container. 3 The parameter defined in the build strategy. To set the value of the dockerfile strategy parameter, specify the Dockerfile location required to build the output image. 4 The location where the built image is pushed. In this procedural example, the built image is pushed to the OpenShift Container Platform cluster internal registry. buildah-example is the name of the current project. Ensure that the specified project exists to allow the image push. Example: Using shp CLI USD shp build create buildah-golang-build \ --source-url="https://github.com/redhat-openshift-builds/samples" --source-context-dir="buildah-build" \ 1 --strategy-name="buildah" \ 2 --dockerfile="Dockerfile" \ 3 --output-image="image-registry.openshift-image-registry.svc:5000/buildah-example/go-app" 4 1 The location where the source code is placed. 2 The build strategy that you use to build the container. 3 The parameter defined in the build strategy. To set the value of the dockerfile strategy parameter, specify the Dockerfile location required to build the output image. 4 The location where the built image is pushed. In this procedural example, the built image is pushed to the OpenShift Container Platform cluster internal registry. buildah-example is the name of the current project. Ensure that the specified project exists to allow the image push. Check if the Build resource is created by using one of the CLIs: Example: Using oc CLI USD oc get builds.shipwright.io buildah-golang-build Example: Using shp CLI USD shp build list Create a BuildRun resource and apply it to the OpenShift Container Platform cluster by using one of the CLIs: Example: Using oc CLI USD oc apply -f - <<EOF apiVersion: shipwright.io/v1beta1 kind: BuildRun metadata: name: buildah-golang-buildrun spec: build: name: buildah-golang-build 1 EOF 1 The spec.build.name field denotes the respective build to run, which is expected to be available in the same namespace. Example: Using shp CLI USD shp build run buildah-golang-build --follow 1 1 Optional: By using the --follow flag, you can view the build logs in the output result. Check if the BuildRun resource is created by running one of the following commands: Example: Using oc CLI USD oc get buildrun buildah-golang-buildrun Example: Using shp CLI USD shp buildrun list The BuildRun resource creates a TaskRun resource, which then creates the pods to execute build strategy steps. Verification After all the containers complete their tasks, verify the following: Check whether the pod shows the STATUS field as Completed : USD oc get pods -w Example output NAME READY STATUS RESTARTS AGE buildah-golang-buildrun-dtrg2-pod 2/2 Running 0 4s buildah-golang-buildrun-dtrg2-pod 1/2 NotReady 0 7s buildah-golang-buildrun-dtrg2-pod 0/2 Completed 0 55s Check whether the respective TaskRun resource shows the SUCCEEDED field as True : USD oc get tr Example output NAME SUCCEEDED REASON STARTTIME COMPLETIONTIME buildah-golang-buildrun-dtrg2 True Succeeded 11m 8m51s Check whether the respective BuildRun resource shows the SUCCEEDED field as True : USD oc get br Example output NAME SUCCEEDED REASON STARTTIME COMPLETIONTIME buildah-golang-buildrun True Succeeded 13m 11m During verification, if a build run fails, you can check the status.failureDetails field in your BuildRun resource to identify the exact point where the failure happened in the pod or container. Note The pod might switch to a NotReady state because one of the containers has completed its task. This is an expected behavior. Validate whether the image has been pushed to the registry that is specified in the build.spec.output.image field. You can try to pull the image by running the following command from a node that can access the internal registry: USD podman pull image-registry.openshift-image-registry.svc:5000/<project>/<image> 1 1 The project name and image name used when creating the Build resource. For example, you can use buildah-example as the project name and sample-go-app as the image name. 1.2. Creating a source-to-image build You can create a source-to-image build and push the created image to a custom Quay repository. Prerequisites You have installed the Builds for Red Hat OpenShift Operator on the OpenShift Container Platform cluster. You have created a ShipwrightBuild resource. You have installed the oc CLI. Optional: You have installed the shp CLI . Procedure Create a Build resource and apply it to the OpenShift Container Platform cluster by using one of the CLIs: Example: Using oc CLI USD oc apply -f - <<EOF apiVersion: shipwright.io/v1beta1 kind: Build metadata: name: s2i-nodejs-build spec: source: 1 type: Git type: Git git: url: https://github.com/redhat-openshift-builds/samples contextDir: s2i-build/nodejs strategy: 2 name: source-to-image kind: ClusterBuildStrategy paramValues: 3 - name: builder-image value: quay.io/centos7/nodejs-12-centos7:master output: image: quay.io/<repo>/s2i-nodejs-example 4 pushSecret: registry-credential 5 EOF 1 The location where the source code is placed. 2 The build strategy that you use to build the container. 3 The parameter defined in the build strategy. To set the value of the builder-image strategy parameter, specify the builder image location required to build the output image. 4 The location where the built image is pushed. You can push the built image to a custom Quay.io repository. Replace repo with a valid Quay.io organization or your Quay user name. 5 The secret name that stores the credentials for pushing container images. To generate a secret of the type docker-registry for authentication, see "Authentication to container registries". Example: Using shp CLI USD shp build create s2i-nodejs-build \ --source-url="https://github.com/redhat-openshift-builds/samples" --source-context-dir="s2i-build/nodejs" \ 1 --strategy-name="source-to-image" \ 2 --builder-image="quay.io/centos7/nodejs-12-centos7" \ 3 --output-image="quay.io/<repo>/s2i-nodejs-example" \ 4 --output-credentials-secret="registry-credential" 5 1 The location where the source code is placed. 2 The build strategy that you use to build the container. 3 The parameter defined in the build strategy.

Note The pod might switch to a NotReady state because one of the containers has completed its task. This is an expected behavior. Validate whether the image has been pushed to the registry that is specified in the build.spec.output.image field. You can try to pull the image by running the following command after logging in to the registry: USD podman pull quay.io/<repo>/<image> 1 1 The repository name and image name used when creating the Build resource. For example, you can use s2i-nodejs-example as the image name. Additional resources Authentication to container registries 1.3. Viewing logs You can view the logs of a build run to identify any runtime errors and to resolve them. Prerequisites You have installed the oc CLI. Optional: You have installed the shp CLI. Procedure View logs of a build run by using one of the CLIs: Using oc CLI USD oc logs <buildrun_resource_name> Using shp CLI USD shp buildrun logs <buildrun_resource_name> 1.4.
