This repository extends [Stackspin](https://open.greenhost.net/stackspin/stackspin)
with extra applications and overrides
Once stabilized, the aim is to contribute as much upstream as possible.
Stackspout is used in day-to-day business
### Overrides
- Adds many Nextcloud extensions and some configuration
-> most notably `external` to add Applications into Nextcloud as hub
Following are the applications Stackspout adds beyond Stackspin.
Unlike Stackspin, there is currently no mechanism to add those individually,
they come in one package with the repository.
Below list is formatted as:
> subdomain: Service (helmrepo, if not by the application authors themselves)
- do: Vikunja [needs upgrade]
- status: Gatus (minicloudlabs)
- design: penpot (truecharts, waiting on PR)
- sprint: taiga (nemonik)
- video: Peertube ([LecygneNoir](https://git.lecygnenoir.info/LecygneNoir/peertube-helm)
)
- call: Jitsi Meet / OpenTalk / Element Call
- wiki: Wiki (maybe wikijs, but I'd like something that integrates with Nextcloud and Markdown/Orgdown)
#### Stale
- people: SuiteCRM (bitnami repo)
- time: Kimai (robjuz repo)
- Preconfigure user settings in Nextcloud, Vikunja and more
> Warning: Lots of experiments happening here!
First [install Stackspin](https://docs.stackspin.net/en/latest/installation/install_stackspin.html).
Then apply the configuration to your cluster:
Done!
Note that the added applications are currently only toggled via repository changes
and integration with Stackspin mechanisms is very rudimentary.
To list the central resource related to this repo:
kubectl get gitrepositories -A
kubectl get kustomization -A -o=jsonpath='{.items[?(@.spec.sourceRef.name=="stackspout")].metadata.name}'
kubectl -n stackspout get helmreleases
kubectl -n stackspout get pods
But there are also ConfigMaps, Secrets, StatefulSets, PVCs, Helmrepos and more...

### Tools
Useful tools for administration:
- my `stack` CLI helper, currently part of my dotfiles:
https://git.jfischer.org/xeruf/dotfiles/src/branch/main/.config/shell/server#L11
- stackspin docs:
https://docs.stackspin.net/en/v2/system_administration/customizing.html
### Guide: Creating OAuth Credentials for an external service
- push an OAuth2Client definition like for the apps,
adjusting `metadata.name` and `spec.secretName` as well as `spec.redirectUris`
- obtain the generated `client_secret` for your application from kubernetes:
kubectl get secret -n flux-system stackspin-APP-oauth-variables --template '{{.data.client_secret}}' | base64 -d
with client_id:
kubectl get secret -n flux-system stackspin-APP-oauth-variables --template '{{.data.client_id}}{{"\n"}}{{.data.client_secret}}{{"\n"}}' | while read in; do echo $in | base64 -d; echo; done
## Explanation - Typical App Deployment in Stackspout with Flux on Kubernetes
The diagram illustrates generically how continuous app deployment works in our Kubernetes cluster
from Infrastructure-as-Code using flux.
Not every app has database, backend and frontend,
but in the end the deployments all work very similarly
so there is no point showing it for each individual app.
Except for the Single-Sign On,
apps also do not really depend on each other.
Explanations:
- deploy :: creates a resource on the cluster from a file in the GitRepository
- create :: creates a resource on the cluster using Kubernetes logic
- ... all :: creates multiple independent resources
All Flux Kustomizations refer to a directory in the GitRepository,
but for clarity I omitted it beyond the initial one.
Clouds are created not via Flux GitOps,
but through one-time scripts.
