## Usage and Components

Note: as of 2021-12-25 this chart is available internally as apps/prod/matrix.


### Sample usage

Setting up matrix for  ...

- the matrix domain "fn.nf"
- the homeserver matrix.fnnf.svc.p10.k8s.ooo
- element web on m.fn.nf

Using automatic DNS from the p10.k8s.ooo cluster:

```
helm upgrade --install --create-namespace --namespace fnnf \
    --set homeServerFQDN=fn.nf,elementWebFQDN=m.fn.nf,letsencryptStaging=no,clusterDomain=p10.k8s.ooo matrix matrix/
```

Setting up matrix.fn.nf in DNS

```
matrix CNAME matrix-element-web.fnnf.svc.p10.k8s.ooo.
```

Creating the two json files
* /.well-known/matrix/server and
* /.well-known/matrix/client
on the fn.nf web server using the samples:

```
% curl -Ls https://m.fn.nf/.well-known/matrix/server > server
% curl -Ls https://m.fn.nf/.well-known/matrix/client > client
```

And finally creating a user:

```
kubectl -n fnnf exec -ti matrix-matrix-synapse-864c4bfb4-4h4cn -c synapse -- register_new_matrix_user http://localhost:8008 -c /config/homeserver.yaml -u admin -p ...  -a
```

### Element-Web

* Includes config.json that is being populated by values.yaml
* Includes nginx on port localhost:8080 (http)
* Includes nginx proxy on port 80+443 (http redirect, https)

The service is reachable as `{{ .Release.Name }}-element-web`.

### Synapse

* homeserver.yaml is created from a ConfigMap in /config-ro
* homeserver.yaml is edited using sed to add the postgres password and
  stored in /config/homeserver.yaml
* Logging configured to stdout

The service is reachable as `{{ .Release.Name }}`.

### Postgres

Tuned with `--no-locale --encoding=UTF8` using `POSTGRES_INITDB_ARGS` (required by synapse).

The service is reachable as `{{ .Release.Name }}-postgres`.

See

* https://www.postgresql.org/docs/9.5/app-initdb.html
* https://hub.docker.com/_/postgres
* https://github.com/matrix-org/synapse/blob/develop/docs/postgres.md


## Missing

- SMTP settings / secrets (ungleich mail + sops?)

### admin user

docker exec -it synapse register_new_matrix_user http://localhost:8008 -c /data/homeserver.yaml --help
