+The A1 Mediator is implemented in Golang.
-Version bumping
----------------
-This project follows semver. When changes are made, the versions are in:
-
-1) ``docs/release-notes.rst``
-
-2) ``setup.py``
-
-3) ``container-tag.yaml``
-
-4) ``integration_tests/a1mediator/Chart.yaml``
-
-5) ``a1/openapi.yaml`` (this is an API version, not a software version; no need to bump on patch changes)
-
-6) in the ric-plt repo that contains a1 helm chart, ``values.yaml``, ``Chart.yml``
-
-
-Version bumping rmr
--------------------
-As of 2020/02/13, A1 and all three integration test receivers use a base image from o-ran-sc.
-The rmr version is in that base image.
-However, the one item in this repo that must be kept in sync is ``rmr-version.yaml``. This controls what rmr gets installed for unit testing.
-
-Version bumping pyrmr
+Running A1 Standalone
---------------------
-rmr-python is the python binding to rmr . Installing rmr per the above does not install it.
-Bumping the rmr python version dependency requires changes in:
-1) ``setup.py``
+The A1 container can be run standalone, which means using an in-memory mock
+version of SDL and a static route table. The host machine must have the RMR
+library and the environment must define the variable `prometheus_multiproc_dir`
+with a value like /tmp. Alternately, use the following command to run A1 as
+a Docker container, using a route table mounted as a file from this git
+repository and exposing the server's HTTP port on the Docker host::
-2) ``integration_tests/Dockerfile-test-delay-receiver``
+ docker run -e USE_FAKE_SDL=True -p 10000:10000 -v `pwd`:/opt/route [DOCKER_IMAGE_ID_HERE]
-3) ``integration_tests/Dockerfile-query-receiver``
+Then test the server with an invocation such as this::
-Run the integration tests after attempting this.
+ curl localhost:10000/a1-p/healthcheck
-Unit Testing
-------------
-Note, before this will work, for the first time on the machine running the tests, run ``./install_deps.sh``. This is only needed once on the machine.
-Also, this requires the python packages ``tox`` and ``pytest``.
-
-::
-
- tox
- open htmlcov/index.html
-
-Alternatively, you can run the unit tests in Docker (this is somewhat less nice because you don't get the pretty HTML)
-
-::
-
- docker build --no-cache -t a1test:latest -f Dockerfile-Unit-Test
Integration testing
-------------------
-This tests A1’s external API with three test receivers. This depends on helm+k8s.
-Build all the containers:
+This tests A1’s external API with three test receivers. This requires
+docker, kubernetes and helm.
+
+Build all the images:
::
- docker build -t a1:latest .; cd integration_tests/; docker build -t testreceiver:latest . -f Dockerfile-test-delay-receiver; docker build -t queryreceiver:latest . -f Dockerfile-query-receiver; cd ..
+ docker build -t a1:latest .
+ cd integration_tests/testxappcode
+ docker build -t delayreceiver:latest -f Dockerfile-delay-receiver .
+ docker build -t queryreceiver:latest -f Dockerfile-query-receiver .
+ docker build -t testreceiver:latest -f Dockerfile-test-receiver .
Then, run all the tests from the root (this requires the python packages ``tox``, ``pytest``, and ``tavern``).
tox -c tox-integration.ini
This script:
-1. Deploys 2 helm charts (4 containers) into a local kubernetes installation
-2. Port forwards a pod ClusterIP to localhost
-3. Uses “tavern” to run some tests against the server
-4. Barrages the server with apache bench
-5. Tears everything down
