Create a Build Configuration

oc new-build is the preferred way to create a new build configuration. oc new-app also creates a build configuration, and for an example of how to do so, see Build and Deploy a JEE Application. The following considerations apply to all types of builds (source, docker and pipeline) that can be created with oc new-build:

• --dry-run can be used to visualize the results of the operation, without modifying anything on the master server.

Source Build

Before declaring the build configuration, define an image stream that will provide the builder image, as shown here:

Create an Image Stream

Then create the build configuration:

oc new-build [--dry-run] --strategy=source --image-stream=eap7

Notes:

• The command shallow clones the specified repository locally, so if the repository certificate is self-signed, it will complain. SSL certificate verification can be turned off as described here: turn off SSL server certificate verification.

Pipeline Build

oc new-build creates source builds by default (--binary is by default 'false').

oc new-build --binary=false ...

Create a build configuration based on source code in the current git repository. The --binary=false says the build should expect source.

Binary Build

oc new-build --binary=true --name=some-binary -i=redhat-openjdk18-openshift

--binary=true makes sure that restrictions associated with binary builds are enforced. It says that instead of expecting a source URL, set the build to expect binary contents. Will disable triggers.

Source Clone Secret

oc set build-secret --source bc/<build-configuration-name'> <secret-name>

Then the secret can be added to the build configuration:

oc new-build .../example.git --build-secret <secret-name>

Set Maximum Duration

spec:
  completionDeadlineSeconds: 1800

Manually Start the Build Process

 oc start-build <buildConfig-name>

The name of a previous build can be specified - it will be used as a starting point.

Options:

• --from-file
• --from-dir
• --from-repo
• --from-archive

View Builds for Project

oc get builds

NAME          TYPE      FROM          STATUS                    STARTED             DURATION
bookstore-1   Source    Git@ad0abda   Failed (AssembleFailed)   About an hour ago   2m43s
bookstore-2   Source    Git@ad0abda   Failed (AssembleFailed)   12 minutes ago      2m16s

Each build has an associated build pod, whose names can be obtained with:

oc get pods

NAME                      READY     STATUS    RESTARTS   AGE
bookstore-1-build         0/1       Error     0          57m
bookstore-2-build         0/1       Error     0          13m

View Build Logs

View build logs associated with a build object:

oc logs [-f] builds/<build-name>

If -f|--follow is used, it specifies that the logs should be streamed.

Viewing the build logs in this manner is similar to following the build pod's logs.

Stop a Build in Progress

oc cancel-build

Delete a Build

oc delete build/<build-name> 

where the build name is among those returned by oc get builds.
