# Stackspin Outwards - Stackspout
2022-03-30 17:04:47 +00:00
This repository extends [Stackspin](https://open.greenhost.net/stackspin/stackspin)
with extra applications and overrides
2023-12-11 16:52:49 +00:00
focused on business use.
Once stabilized, the aim is to contribute as much upstream as possible.
2022-03-30 17:04:47 +00:00
Stackspout is used in day-to-day business
2022-11-16 11:16:18 +00:00
with a double-digit user number,
so all experiments happen carefully.
2023-12-11 16:52:49 +00:00
Still, it is an experimental offering.
2022-03-30 20:11:12 +00:00
## Customizations
2022-03-30 20:11:12 +00:00
### Overrides
- Adds many Nextcloud extensions and some configuration
2023-12-11 16:52:49 +00:00
-> most notably `external` to add Applications into Nextcloud as hub
### New Applications
2024-04-08 15:21:15 +00:00
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 provided by the service authors)
2023-12-11 16:52:49 +00:00
#### Stable including Single-Sign-On
2024-04-04 10:32:18 +00:00
- forge: Forgejo
- do: Vikunja
#### No SSO
- ninja: InvoiceNinja
- support: Zammad
- flow: n8n (8gears)
- meet: cal.com (pyrrha)
- status: Gatus (minicloudlabs)
#### Planned
2024-04-04 10:32:18 +00:00
- design: penpot (truecharts, waiting on PR)
- sprint: taiga (nemonik)
- video: Peertube ([LecygneNoir](https://git.lecygnenoir.info/LecygneNoir/peertube-helm)
)
- call: Jitsi Meet / OpenTalk
- wiki: Wiki (maybe wikijs, but I'd like something that integrated with Nextcloud and Markdown/Orgdown)
#### Ideas
- link: URL Shortener
2023-12-11 16:52:49 +00:00
- connect: Bonfire
2024-04-04 10:32:18 +00:00
#### Stale
- people: SuiteCRM (bitnami repo)
- time: Kimai (robjuz repo)
#### Functionally
2023-12-11 16:52:49 +00:00
- Nextcloud too slow - add Redis?
- Preconfigure user settings in Nextcloud, Vikunja and more
2023-12-11 16:52:49 +00:00
## Setup
> Warning: Lots of experiments happening here!
2022-03-30 20:11:12 +00:00
2023-12-11 16:52:49 +00:00
First [install Stackspin](https://docs.stackspin.net/en/latest/installation/install_stackspin.html).
Then apply the configuration to your cluster:
2022-03-30 20:11:12 +00:00
```sh
./install.sh
2022-03-30 20:11:12 +00:00
```
2023-12-11 16:52:49 +00:00
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:
2022-03-30 20:11:12 +00:00
```sh
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
2022-03-30 20:11:12 +00:00
```
2023-12-11 16:52:49 +00:00
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.
