Ceph make check in docker [feedly]

Ceph make check in docker
// Ceph

After Ceph is built from sources, unit and functional tests can be run with make check. Delegating the execution to a container makes it possible to:

• keep working on the sources without disrupting the run
• run functional tests that require root privileges without modifying the development environment
• check various operating systems

The src/test/docker-test-helper.sh library can be used from the command line:

$ test/docker-test.sh --os-type ubuntu --os-version 14.04 make check &  $ test/docker-test.sh --os-type centos --os-version centos7 make check &  

Each run uses a clone of the current repository and pulls from origin before executing the command. For instance, if running from /srv/ceph, the centos run will run make check in /srv/ceph-centos-centos7 which is bind mounted in the container. A possible workflow is:

• work
• commit
• test/docker-test.sh make check which pulls the latest commits
• keep working
• check the make check output

In case an error happens, debugging starts by running a shell in the container

$ test/docker-test.sh --os-type ubuntu --os-version 14.04 --shell  remote: Counting objects: 10, done.  remote: Compressing objects: 100% (10/10), done.  remote: Total 10 (delta 8), reused 0 (delta 0)  Unpacking objects: 100% (10/10), done.  From /home/loic/software/ceph/ceph   + 15046fe...8a39cad wip-9665 -> origin/wip-9665  HEAD is now at 8a39cad autotools: add --enable-docker  loic@203c085f3dc1:/srv/ceph-ubuntu-14.04$  

The first time test/docker-test.sh runs, it creates a docker images populated with the packages necessary to compile and run Ceph. This lowers the overhead to run a test in the container:

$ time test/docker-test.sh --os-type ubuntu --os-version 14.04 unittest_str_map  HEAD is now at 8a39cad autotools: add --enable-docker  Running main() from gtest_main.cc  [==========] Running 2 tests from 1 test case.
