mozilla-django-oidc didn't add the https://
prefix to the redirect_uri.
We set the option SECURE_PROXY_SSL_HEADER to
('HTTP_X_FORWARDED_PROTO', 'https') in the
settings.py file to force the https prefix.
Enabled Dockerflow Django app by activating liveness probes. The previously
unavailable routes such as `__heartbeat__` and `__lbheartbeat__` are now
accessible. New endpoints include:
* GET /__version__
* GET /__heartbeat__
* GET /__lbheartbeat__
In development, sessions are saved in local memory. It's working well,
however it doesn't adapt to a kubernetized setup. Several pods need
to access the current sessions, which need to be stored in a single
source of truth.
With a local memory cache, pods cannot read session saved in other pods.
We end up returning 401 errors, because we cannot authenticate the user.
I preferred setting up a proper cache than storing sessions in database,
because in the long run it would be a performance bottleneck. Cache will
decrease data access latency when reading current sessions.
I added a Redis cache backend to the production settings. Sessions would
be persisted to Redis. In K8s, a Redis operator will make sure the cached
data are not lost.
Two new dependencies were added, redis and django-redis.
I followed the installation guide of django-redis dependency. These
setting were tested deploying the app to a local K8s cluster.
