# Cubieserver - Jack's Homelab
Welcome to the Infrastructure as Code repository serving as the source of truth for Jack's Homelab - "Cubieserver".
> Note: the canonical repository is . The [Github mirror](https://github.com/jacksgt/homelab) is intended for disaster recovery purposes (to avoid the chicken-and-egg problem when bootstrapping the infrastructure).
The installation, setup and configuration of all software involved is handled by two components:
* **Ansible**: used for provisioning physical machines until they can join the Kubernetes cluster
* *this is currently still in development*
* **Flux**: deploys all services on top of Kubernetes (with local Kustomize manifests and external Helm charts)
* *find more details in the [flux directory](./flux/README.md)*
An overview of the currently running services can be found on the [Cubieserver homepage](https://www.cubieserver.de).
## Tips & Tricks
### Traefik
To access traefik dashboard at , run:
```sh
ns=traefik; kubectl -n "$ns" port-forward $(kubectl -n "$ns" get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000
```
### PostgreSQL Size
Get size of Postgres databases:
```
psql -h -U
\l+
```
Get size of Postgres tables:
```
\c
\d+
```
## Truncate all tables in MySQL
Truncates all tables of database `DB_NAME`:
```
SELECT Concat('TRUNCATE TABLE ',table_schema,'.',TABLE_NAME, ';')
FROM INFORMATION_SCHEMA.TABLES WHERE table_schema IN ('DB_NAME');
```
Might need to set `SET FOREIGN_KEY_CHECKS=0;` before running (revert to original behavior with `SET FOREIGN_KEY_CHECKS=1;`)

## Import MySQL dump
```
mysql -h HOSTNAME -u USER -p -D DB_NAME -C < dump.sql
```
optionally use `-f` to continue despite SQL errors
## Run the database cronjob now
```sh
kubectl -n mariadb create job --from=cronjob/mariadb-backup "mariadb-backup-$(date +"%Y%m%d-%H%M%S")"
kubectl -n mariadb get jobs -w
```
## XMPP DNS records

record name | TTL | class | type | priority | weight | port | target
_xmpp-client._tcp.example.com | 3600 | IN | SRV | 0 | 5 | 5222 | xmpp.example.com
_xmpp-server._tcp.example.com | 3600 | IN | SRV | 0 | 5 | 5269 | xmpp.example.com
## Analyze and optimize MySQL tables
```sh
# To check all tables in all databases:
$ mysqlcheck -h HOST -u root -p --all-databases -c
# To analyze all tables in all databases:
$ mysqlcheck -h HOST -u root -p --all-databases -a
# To repair all tables in all databases:
$ mysqlcheck -h HOST -u root -p --all-databases -r
# To optimize all tables in all databases:
$ mysqlcheck -h HOST -u root -p --all-databases -o
# Do the same for a single table
$ mysqlcheck -h HOST -u root -p $DB $TABLE -c/-a/-r/-o
```

## Show size of tables in MySQL database
```mysql
SELECT
TABLE_NAME AS `Table`,
ROUND((DATA_LENGTH + INDEX_LENGTH) / 1024 / 1024) AS `Size (MB)`
FROM
information_schema.TABLES
WHERE
TABLE_SCHEMA = "$DATABASE"
ORDER BY
(DATA_LENGTH + INDEX_LENGTH)
DESC;
