Configuration Issues

We currently can no login even after python manage.py createsuperuser --noinput in the taiga-back-deployment container. What might help: https://docs.taiga.io/setup-production.html#taiga-back

Note: taiga-manage,-back und -async verwenden die gleichen docker images mit unterschiedlichen entry-points.

Steps to start and get an admin user

Philosophy: First create the superuser, then populate the DB. https://docs.taiga.io/setup-production.html#taiga-back https://docs.taiga.io/setup-production.html#_configure_an_admin_user https://github.com/kaleidos-ventures/taiga-back/blob/main/docker/entrypoint.sh

In the init container we create the super user. Difference between init-container and container: CELERY_ENABLED: false The init container gets the following command and args:

command: ["/bin/bash"]
args: ["-c", "source /opt/venv/bin/activate && python manage.py createsuperuser"]

Thus the dockerfile default entrypoint is ignored.

Problem: Login using this method is still not available with the proposed credentials.

Option 1: Init container, currently under test

Create an init container (celery disabled) with the python manage.py command and the taiga-manage createsuperuser args

Option 2: Single container

Create a single container that has celery disabled at the beginning. Runs the following cmds:

• python manage.py taiga-manage createsuperuser
• enable celery
• execute entrypoint.sh

HTTPS

Terminiert am ingress. Wie interagiert das mit taiga? Eventuell wird dies hier relevant: https://github.com/kaleidos-ventures/taiga-docker#session-cookies-in-django-admin

Docker Compose (DC) -> Kubernetes

We implemented a deployment and service in kubernetes for each DC Service. Configmaps and secrets were implemented, to avoid redundancy and readability also to increase security a bit. For all volumes described in DC we implemented PVCs and volume refs.

A config.py (used for taiga-back ) was introduced for reference. A config.json (used for taiga-front ) was introduced for reference. NB: It might be necessary to actually map both from a config map to their respective locations in taiga-back and taiga-front. Description for that is here. A mix of both env-vars and config.py in one container is not possible.

depends_on

We currently assume, that it will work without explicitly defining a startup order.

DC Networking

https://github.com/compose-spec/compose-spec/blob/master/spec.md

The hostname KW sets the hostname of a container. It should have no effect on the discoverability of the container in kubernetes.

The networks KW defines the networks that service containers are attached to, referencing entries under the top-level networks key. This should be taken care of by our kubernetes installation.

Pod to Pod Possible Communications

Taiga containers that need to reach other taiga containers: taiga-async -> taiga-async-rabbitmq taiga-events -> taiga-events-rabbitmq This is not quite clear, but probably solved with the implementation of services.

Deployments

Separate deployments exist for each of the taiga modules:

Taiga-back reads many values in config.py from env vars as can be seen in the taiga-back config.py. These are read from configmaps and secrets in the deployment.

Purpose

Status

Try out

Usage

You need:

...

• and a kubernetes cluster provisioned by provs

... Let c4k-taiga generate your .yaml file.
Apply this file on your cluster with kubectl apply -f yourApp.yaml.
Done.

resource requests and limits

You may want to adjust the resource requests and limits of the build and init containers to your specific scenario.
