This commit is working in progress. I have added an extra chart to take
benefits of the Redis operator developed by Indie hoster.
When using the dev environment, I used bitnami redis chart to deploy
a Redis service with authentication disable.
CSRF trusted origins are set using an environment variable. The env
value was wrongly name to CORS_ALLOWED_ORIGINS, which doesn't exist
in our Django configurations. I fixed this minor issue.
Set OIDC secrets for the dev environment. Please note that we use different
secrets between dev and staging. Why? Benoit created two client id, thus we
could easily tests Agent Connect feature from the local host and the staging
one.
The local host is desk.127.0.0.1.nip.io. If this value change at any time,
please consider asking Benoit to update the host value linked to the dev
client id.
Thx @rouja for your help on deploying Desk. This commit slightly modifies
helm charts and helmfile to prepare the initial project deployment in a
staging environment.
@rouja updates:
- added secrets files for dev and staging environments (dev's one is empty)
- disable ingress by default, to avoid any security issue
- added an extra chart to benefit from Indie hoster Postgres operator
Thx to this commit we deployed a first draft version figured out
that the Django session were broken. We are using a cache session engine,
and wrongly configure cache backend to local memory. Thus, Django server
is not able to resolve the session, and enters in an infinite loop to
log-in the user.
Please note that this Helmfile is uncomplete, it lacks services as
redis, celery, mail ... which are declared in the Docker Compose file
but not yet used in development and production images.
Thus, to run the Desk Helm chart, we only add a postgres database to run the
Django backend server, and apply migrations.
For now, this Helmfile is quite hard to test in dev environment, because the
frontend redirects automatically to the SSO login page. We cannot really
assess if backend and frontend are working properly. We might adjust some
configurations after the first deployment in stagging.
(We are a bit in rush, to respect the current sprint deadline.)
Development values points https://desk.127.0.0.1.nip.io URL. Please note that
the frontend image for now has been built with this URL for the backend address.
Meaning that we either need to rebuild and publish a frontend image with the
staging URL when deploying the project, or enhance our frontend image, to pass
the backend URL at runtime.
First, thanks a LOT @rouja for your help along the way.
This commit propose a first draft of Helm chart to prepare deployment.
It follows Plane's Helm Chart, hosted on the shared team repo,
please https://github.com/numerique-gouv/helm-charts, PR #11
It offers advanced templating function under _helpers.tpl, an auto-generated
README file when running ./generate-readme.sh, and a clear files structure.
The chart itself is quite simple. We have two deployments, one for the
frontend and one for the backend. Both need a dedicated service, which are
exposed using a common ingress. Frontend is accessible from the / path and
backend's from /api path.
Please note, we added a backend job to migrate the database when deploying
backend's pods. This job should be auto-cleaning itself 100s after it completes
to avoid any error when syncing helm.
values.yaml file is quite pristine, all common env variables will be set
in helmfile configuration.
Deploying frontend static files through kubernetes is temporary, we plan to
either remplace it by an external CDN or use minio to host static output in
a S3 bucket within the cluster.
