 ### Compile StarRocks using the image compiled in the previouse step
 For specific steps, please refer to the [documentation](https://docs.starrocks.com/en-us/main/administration/Build_in_docker). For example, if we choose to use the `branch-2.2` to compile, `{version}` in the documentation will be `branch-2.2-rc`.
