$ oc describe build <build_name>
7.5.1. Accessing BuildConfig logs
You can access BuildConfig logs using the web console or the CLI.
Procedure

7.5.3. Enabling log verbosity
You can enable a more verbose output by passing the BUILD_LOGLEVEL environment variable as part of the sourceStrategy or dockerStrategy in a BuildConfig.
An administrator can set the default build verbosity for the entire OpenShift Container Platform instance by configuring env/BUILD_LOGLEVEL. This default can be overridden by specifying BUILD_LOGLEVEL in a given BuildConfig. You can specify a higher priority override on the command line for non-binary builds by passing --build-loglevel to oc start-build.
Available log levels for source builds are as follows:
| Level 0 |
Produces output from containers running the |
| Level 1 | Produces basic information about the executed process. |
| Level 2 | Produces very detailed information about the executed process. |
| Level 3 | Produces very detailed information about the executed process, and a listing of the archive contents. |
| Level 4 | Currently produces the same information as level 3. |
| Level 5 | Produces everything mentioned on previous levels and additionally provides docker push messages. |
Procedure
To enable more verbose output, pass the
BUILD_LOGLEVELenvironment variable as part of thesourceStrategyordockerStrategyin aBuildConfig:sourceStrategy: ... env: - name: "BUILD_LOGLEVEL" value: "2" 1- 1
- Adjust this value to the desired log level.
