# Kubernetes Walkthrough
This article will walk you through getting Kometa set up and running in Kubernetes. It will cover:
1. Creating the Kubernetes CronJob
2. Creating configuration files as Config Maps
3. (Advanced) Creating dynamic configuration files with an Init Container
## Prerequisites.
This walk through assumes you are familiar with Kubernetes concepts and have an exiting cluster to deploy into. If you
do not, but are interested, [minikube](https://minikube.sigs.k8s.io/docs/start/) is a great place to start.
## Creating the Kubernetes CronJob
When running Kometa in Kubernetes, executing it as a CronJob gives us the ability to define a schedule for execution and have
Kubernetes manage the rest.
Some parts of this to tweak to your needs:
1. The namespace should be set to whatever you desire, in this example it runs in the `media` namespace.
2. The schedule, in this example it runs at 00:00 UTC. [https://crontab.guru/](https://crontab.guru/) is a good
site if you aren't sure on how to create a schedule.
```
apiVersion: batch/v1
kind: CronJob
metadata:
name: kometa
namespace: media
spec:
schedule: "0 0 * * *"
jobTemplate:

restartPolicy: OnFailure
```
> :warning: If you are using [Longhorn](https://longhorn.io/) as your storage class, you should omit the `spec.jobTemplate.spec.template.spec.securityContext` node to fix file permission errors.
This CronJob also requires
1. A Persistent Volume Claim
2. 3 Config Maps (see next section)
The Persistent Volume Claim (PVC) can be as simple as:
```
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
labels:
app: kometa
name: kometa
namespace: media
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 128Mi
```
## Creating the Config Maps
In Kubernetes, configurations are managed via Config Maps. So we deploy the configurations for Kometa as config maps. The
minimum requirement is the Kometa config, but the example here assumes you have a separate config for movies and tv shows.
### Kometa Config
Here's a config map for the `config.yml` file for Kometa. Note there are many placeholders that will need update based on
your environment and needs.
Follow the [Trakt Attributes](../../config/trakt.md) directions for generating the OAuth authorization
values.
```
apiVersion: v1

### Movie Config Map
Config maps for collections (movies in this example) are more simple!
```
apiVersion: v1
data:
movies.yaml: |
collections:
Trakt Popular:
trakt_popular: 200
collection_order: custom
sync_mode: sync
sort_title: Traktpopular
summary: The most popular movies for all time.
radarr_add_missing: true
radarr_search: true
radarr_monitor: true
Tautulli Most Popular Movies:
sync_mode: sync
collection_order: custom
tautulli_watched:
list_days: 180
list_size: 10
list_minimum: 1
kind: ConfigMap
metadata:
name: movie-config
namespace: media
```
### TV Config Map
```
apiVersion: v1
data:
tv.yaml: |
collections:
Most Popular:
smart_label: originally_available.desc
sync_mode: sync
imdb_search:
type: tv_series, tv_mini_series
limit: 10
summary: The 10 most popular shows across the internet
sonarr_add_missing: true
sonarr_search: true
sonarr_monitor: pilot
Tautulli Most Popular:
sync_mode: sync
collection_order: custom
summary: The 10 most popular shows from Plex users
tautulli_popular:
list_days: 180
list_size: 10
kind: ConfigMap
metadata:
name: tv-config
namespace: media
```
## Creating dynamic configuration files with an Init Container
IMDb search results may include results for media which has not yet been released, resulting in a collection that is
incomplete. In order to solve for this you can replace a static config map with a config file that is (re)generated when
the cronjob starts each time. This can be done by including an init container which renders a
[Jinja](https://jinja.palletsprojects.com/en/3.0.x/templates/) template to a file in the PVC.
### Including the Init Container in the Cron Job
NOTE the environment value named `JINJA_DEST_FILE` is the resulting name of the generated config file.
```
apiVersion: batch/v1
kind: CronJob
metadata:
name: kometa
namespace: media
spec:
schedule: "0 0 * * *"
jobTemplate:
spec:
template:
spec:
securityContext:
runAsUser: 1000
runAsGroup: 1000
initContainers:
- name: render-dynamic-config
image: chrisjohnson00/jinja-init:v1.0.0
env:
# source and destination files
- name: JINJA_SRC_FILE
value: /config_src/tv.yaml
- name: JINJA_DEST_FILE
value: /config/tv.yaml
# let's be verbose
- name: VERBOSE
value: "1"
volumeMounts:
# configMap mount point
- name: tv-config-template
mountPath: /config_src
# target directory mount point; the final config file will be created here
- name: config
mountPath: /config
containers:
- name: kometa
image: kometateam/kometa:latest
imagePullPolicy: Always
args: [ "--run", "--read-only-config" ]
resources:
limits:
cpu: 100m
memory: 256Mi
requests:
cpu: 100m
memory: 125Mi
volumeMounts:
- name: config
mountPath: /config
- name: kometa-config
mountPath: /config/config.yml
subPath: config.yml
- name: movie-config
mountPath: /config/movies.yaml
subPath: movies.yaml
volumes:
- name: config
persistentVolumeClaim:
claimName: kometa
- configMap:
name: kometa-config
name: kometa-config
- configMap:
name: movie-config
name: movie-config
- configMap:
name: tv-config-jinja-template
name: tv-config-template
restartPolicy: OnFailure
```
### Templatizing your configuration
`{{ now().strftime('%Y-%m-%d') }}` is the Jinja code, which when rendered will be replaced with the current date in
YYYY-MM-DD format. `now()` is a special method defined in the Python code running in the init container to allow access
to the current date, so changing the output format is as simple as changing the string in `strftime` to your desired
date/time format for your list source.
```
apiVersion: v1

tv.yaml: |
