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. 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.

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.
