+Developer Guide
===============
-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``
-
-6) ``a1/openapi.yml`` (this is an API version, not a software version)
-
-7) in the it/dep repo that contains a1 helm chart, ``values.yaml``, ``Chart.yml``
-
-Version bumping rmr-python
-==========================
-rmr-python is a critial dependency of A1. Bumping the rmr version dependency requires changes in:
-
-1) ``setup.py``
+.. contents::
+ :depth: 3
+ :local:
-2) ``Dockerfile``
+Tech Stack
+----------
-3) ``integration_tests/Dockerfile``
+The A1 Mediator is implemented in Golang.
-Run the integration tests after attempting this.
-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``.
+Running A1 Standalone
+---------------------
-::
+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::
- tox
- open htmlcov/index.html
+ docker run -e USE_FAKE_SDL=True -p 10000:10000 -v `pwd`:/opt/route [DOCKER_IMAGE_ID_HERE]
-Alternatively, you can run the unit tests in Docker (this is somewhat less nice because you don't get the pretty HTML)
+Then test the server with an invocation such as this::
-::
+ curl localhost:10000/A1-P/v2/healthcheck
- docker build --no-cache -t a1test:latest -f Dockerfile-Unit-Test
Integration testing
-===================
-This tests A1’s external API with two test receivers. This depends on helm+k8s, meaning you cannot run this if this is not installed.
+-------------------
-Unlike the unit tests, however, this does not require rmr to be installed on the base system, as everything
-runs in Docker, and the Dockerfiles provide/install rmr.
+This tests A1’s external API with three test receivers. This requires
+docker, kubernetes and helm.
-First, build the latest A1 you are testing (from the root):
-::
+Build all the images:
- docker build --no-cache -t a1:latest .
+::
-Note that this step also runs the unit tests, since running the unit tests are part of the Dockerfile for A1.
+ 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 .
-If you've never run the integration tests before, build the test receiver, which is referenced in the helm chart:
-::
- cd integration_tests
- docker build --no-cache -t testreceiver:latest .
+Then, run all the tests from the root (this requires the python packages ``tox``, ``pytest``, and ``tavern``).
-Finally, 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 3 helm charts 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
-
-Unless you're a core A1 developer, you should probably stop here. The below instructions
-are for running A1 locally, without docker, and is much more involved (however useful when developing a1).
-
-Running locally
-===============
-
-1. Before this will work, for the first time on that machine, run ``./install_deps.sh``
-
-2. It also requires rmr-python installed. (The dockerfile does this)
-
-3. Create a ``local.rt`` file and copy it into ``/opt/route/local.rt``.
- Note, the example one in ``integration_tests`` will need to be modified for
- your scenario and machine.
-
-4. Copy a ric manifest into ``/opt/ricmanifest.json`` and an rmr mapping
- table into ``/opt/rmr_string_int_mapping.txt``. You can use the test
- ones packaged if you want:
-
- ::
-
- cp tests/fixtures/ricmanifest.json /opt/ricmanifest.json
- cp tests/fixtures/rmr_string_int_mapping.txt /opt/rmr_string_int_mapping.txt
-
-5. Then:
-
- ::
-
- sudo pip install -e .
- set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; set -x RMR_RCV_RETRY_INTERVAL 500; set -x RMR_RETRY_TIMES 10;
- /usr/bin/run.py
-
-
-There are also two test receivers in ``integration_tests`` you can run locally.
-The first is meant to be used with the ``control_admission`` policy
-(that comes in test fixture ric manifest):
-
-::
-
- set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; python receiver.py
-
-The second can be used against the ``test_policy`` policy to test the
-async nature of A1, and to test race conditions. You can start it with
-several env variables as follows:
-
-::
-
- set -x LD_LIBRARY_PATH /usr/local/lib/; set -x RMR_SEED_RT /opt/route/local.rt ; set -x TEST_RCV_PORT 4563; set -x TEST_RCV_RETURN_MINT 10001; set -x TEST_RCV_SEC_DELAY 5; set -x TEST_RCV_RETURN_PAYLOAD '{"ACK_FROM": "DELAYED_TEST", "status": "SUCCESS"}' ; python receiver.py
-
-To test the async nature of A1, trigger a call to ``test_policy``, which
-will target the delayed receicer, then immediately call
-``control_admission``. The ``control_admission`` policy return should be
-returned immediately, whereas the ``test_policy`` should return after
-about ``TEST_RCV_SEC_DELAY 5``. The ``test_policy`` should not block A1
-while it is sleeping, and both responses should be correct.
-
-::
- curl -v -X PUT -H "Content-Type: application/json" -d '{}' localhost:10000/ric/policies/test_policy
- curl -v -X PUT -H "Content-Type: application/json" -d '{ "enforce":true, "window_length":10, "blocking_rate":20, "trigger_threshold":10 }' localhost:10000/ric/policies/admission_control_policy
- curl -v localhost:10000/ric/policies/admission_control_policy
- curl -v localhost:10000/a1-p/healthcheck
