What command streams logs from a specific build named jhost in real time?

• A. oc logs -f build jhost-1
• B. oc start-build <buildconfig_name> --env=<key>=<value>
• C. oc set triggers bc/name --from-image=project/image:tag
• D. oc delete all -l app=appname

Answer: (A)

Streaming logs from a specific build in real time relies on following the log output of that Build resource. The oc logs command fetches the logs for a resource, and the -f option makes it continuous, printing new lines as the build progresses. By targeting the Build resource type with the exact build name (the one named jhost-1), you get a live feed of that build’s log output. The other options don’t provide a live log stream for an existing build: starting a build triggers a new one; setting triggers changes how builds are started or triggered; deleting resources removes them.
