## TL;DR

```console
helm repo add my-repo https://charts.bitnami.com/bitnami
helm install my-release my-repo/gitea
```

## Introduction

This chart bootstraps a [Gitea](https://github.com/bitnami/containers/tree/main/bitnami/gitea) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

It also packages the [Bitnami PostgreSQL chart](https://github.com/bitnami/charts/tree/main/bitnami/postgresql) which is required for bootstrapping a PostgreSQL deployment as a database for the Gitea application.

Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm repo add my-repo https://charts.bitnami.com/bitnami
helm install my-release my-repo/gitea
```

The command deploys Gitea on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

```console
helm install my-release \
  --set adminUsername=user,giteaPassword=password,postgresql.auth.rootPassword=secretpassword \
    my-repo/gitea
```

The above command sets the Gitea administrator account username and password to `user` and `password` respectively. Additionally, it sets the PostgreSQL `root` user password to `secretpassword`.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml my-repo/gitea
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Image

The `image` parameter allows specifying which image will be pulled for the chart.

#### Private registry

If you configure the `image` value to one in a private registry, you will need to [specify an image pull secret](https://kubernetes.io/docs/concepts/containers/images/#specifying-imagepullsecrets-on-a-pod).

1. Manually create image pull secret(s) in the namespace. See [this YAML example reference](https://kubernetes.io/docs/concepts/containers/images/#creating-a-secret-with-a-docker-config). Consult your image registry's documentation about getting the appropriate secret.
2. Note that the `imagePullSecrets` configuration value cannot currently be passed to helm using the `--set` parameter, so you must supply these using a `values.yaml` file, such as:

    ```yaml
    imagePullSecrets:
      - name: SECRET_NAME
    ```

3. Install the chart

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

## Persistence

The [Bitnami Gitea](https://github.com/bitnami/containers/tree/main/bitnami/gitea) image stores the Gitea data and configurations at the `/bitnami/gitea` path of the container.

Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
See the [Parameters](#parameters) section to configure the PVC or to disable persistence.

### Existing PersistentVolumeClaim

1. Create the PersistentVolume
2. Create the PersistentVolumeClaim
3. Install the chart

```console
helm install my-release --set persistence.existingClaim=PVC_NAME my-repo/gitea
```

### Host path

#### System compatibility

- The local filesystem accessibility to a container in a pod with `hostPath` has been tested on OSX/MacOS with xhyve, and Linux with VirtualBox.
- Windows has not been tested with the supported VM drivers. Minikube does however officially support [Mounting Host Folders](https://minikube.sigs.k8s.io/docs/handbook/mount/) per pod. Or you may manually sync your container whenever host files are changed with tools like [docker-sync](https://github.com/EugenMayer/docker-sync) or [docker-bg-sync](https://github.com/cweagans/docker-bg-sync).

#### Mounting steps

1. The specified `hostPath` directory must already exist (create one if it does not).
2. Install the chart

    ```console
    helm install my-release --set persistence.hostPath=/PATH/TO/HOST/MOUNT my-repo/gitea
    ```

    This will mount the `gitea-data` volume into the `hostPath` directory. The site data will be persisted if the mount path contains valid data, else the site data will be initialized at first launch.
3. Because the container cannot control the host machine's directory permissions, you must set the Gitea file directory permissions yourself
