Openstack Oslo labs
oslo.labs aim to help you to debug Openstack Oslo libraries, by setting up automatically a complete environment ready for hacking and debug.
Labs provide some preconfigured scenario to help you to test and debug
oslo's libraries and also oslo's projects requirements like python-memcached,
dogpile.cache, etc...
Each change made on an oslo library or on requirements in your lab are synchronized with your github forks of each projects, this allow you to quickly iterate on your changes in your lab, and when you think you are ready you can rebase all your changes properly to a dedicated branch ready for review.
$ git clone git@github.com:4383/oslo.labs.git
$ cd oslo.labsChoose the lab you want to use:
$ ./list.sh
oslo.cache's labs:
- memcache_pool_backendStart your lab:
$ ./run.sh oslo.cache/memcache_pool_backend

lab successfully settled!
==============================================================
Join your lab by using:
docker exec -it oslo.cache-memcache_pool_backend.lab /bin/zsh
Stop your lab by using:
docker-compose -f oslo.cache/memcache_pool_backend/docker-compose-lab.yml down
==============================================================Now enter in your lab:
$ docker exec -it oslo.cache-memcache_pool_backend.lab /bin/zsh
lab $ python lab/app.py
lab $ ls ~/debug # here are all the libs you may want to modify for your testsCreate a new lab from an existing template:
$ # list existing templates
$ ./new --list
$ # create a new lab named testXYZ in the oslo.cache scope
$ # from the default template
$ ./new --lab-group=oslo.cache testXYZ
$ # more options are availables
$ ./new -hA lab is an environment automatically setup with many services. Oslo libraries aim to to give an abstraction between services and users. A services could be a memcached server or rabbitmq server by example, and oslo's users are commonly openstack services like nova, neutron, etc...
A lab provide some scripts to give you an abstraction and emulate openstack services.
