How do you set the environment variable BUILD_LOGLEVEL to 4 in the build config named phpbuild?

• A. oc set env buildconfig/phpbuild BUILD_LOGLEVEL=4
• B. oc set env buildconfig/phpbuild BUILD_LOGLEVEL="4"
• C. oc set env bc/phpbuild BUILD_LOGLEVEL="4"
• D. oc set env bc/phpbuild BUILD_LOGLEVEL=4

Answer: (B)

Setting an environment variable on a BuildConfig in OpenShift is done with the oc set env command, targeting the BuildConfig resource and providing KEY=VALUE pairs. For a BuildConfig named phpbuild, you reference the resource as buildconfig/phpbuild and assign the variable BUILD_LOGLEVEL to a string value. Quoting the value ensures it’s treated as a literal string, which is a safe and clear practice even for numeric values. So the command oc set env buildconfig/phpbuild BUILD_LOGLEVEL="4" correctly applies BUILD_LOGLEVEL with the value "4" to that BuildConfig. Using the short form bc/phpbuild or omitting quotes can work in some contexts, but the quoted, full-resource form is the most explicit and reliable.
