-## Prerequisites
+## High Availability
 
-- Kubernetes 1.12+
+Since version 9.0.0 this chart supports running Gitea and it's dependencies in HA mode.
-- Helm 3.0+
+Care must be taken for production use as not all implementation details of Gitea core are officially HA-ready yet.
-- PV provisioner for persistent data support
 
-## Examples
+Deploying a HA-ready Gitea instance requires some effort including using HA-ready dependencies.
+See the [HA Setup](docs/ha-setup.md) document for more details.

+Custom themes can be added via k8s secrets and referencing them in `values.yaml`.
+
+The [http provider](https://registry.terraform.io/providers/hashicorp/http/latest/docs/data-sources/http) is useful here.

+    readOnly: true
+    mountPath: "/data/gitea/public/assets/css"

+
+```hcl

+  metadata {
+    name      = "gitea-themes"
+    namespace = "gitea"

+
+## Renovate
+
+To be able to use a digest value which is automatically updated by `Renovate` a [customManager](https://docs.renovatebot.com/modules/manager/regex/) is required.
+Here's an examplary `values.yml` definition which makes use of a digest:
+
+```yaml
+image:
+  repository: gitea/gitea
+  tag: 1.20.2
+  digest: sha256:6e3b85a36653894d6741d0aefb41dfaac39044e028a42e0a520cc05ebd7bfc3f
+```
+
+By default Renovate adds digest after the `tag`.
+To comply with the Gitea helm chart definition of the digest parameter, a "customManagers" definition is required:
+
+```json
+"customManagers": [
+  {
+    "customType": "regex",
+    "description": "Apply an explicit gitea digest field match",
+    "fileMatch": ["values\\.ya?ml"],

+    "autoReplaceStringTemplate": "{{depName}}\n{{indentation}}tag: {{newValue}}\n{{indentation}}digest: {{#if newDigest}}{{{newDigest}}}{{else}}{{{currentDigest}}}{{/if}}"

+Chart 9.6.0 ships with Gitea 1.21.0.

+
+</details>
+
+<details>
+
+<summary>To 9.0.0</summary>
+
+This chart release comes with many breaking changes while aiming for a HA-ready setup.
+Please go through all of them carefully to perform a successful upgrade.
+Here's a brief summary again, followed by more detailed migration instructions:
+
+- Switch from `Statefulset` to `Deployment`
+- Switch from `Memcached` to `redis-cluster` as the default session and queue provider
+- Switch from `postgres` to `postgres-ha` as the default database provider
+- A chart-internal PVC bootstrapping logic
+  - New `persistence.mount`: whether to mount an existent PVC (even if not creating it)
+  - New `persistence.create`: whether to create a new PVC
+  - Renamed `persistence.existingClaim` to `persistence.claimName`
+
+While not required, we recommend to start with a RWX PV for new installations.
+A RWX volume is required for installation aiming for HA.
+
+If you want to stay with a pre-existing RWO PV, you need to set
+
+- `persistence.mount=true`
+- `persistence.create=false`
+- `persistence.claimName` to the name of your existing PVC.
+
+If you do not, Gitea will create a new PVC which will in turn create a new PV.
+If this happened to you by accident, you can still recover your data by setting using the settings from above in a subsequent run.
+
+If you want to stay with a `memcache` instead of `redis-cluster`, you need to deploy `memcache` manually (e.g. from [bitnami](https://github.com/bitnami/charts/tree/main/bitnami/memcached)) and set
+
+- `cache.HOST = "<memcache connection string>"`
+- `cache.ADAPTER = "memcache"`
+- `session.PROVIDER = "memcache"`
+- `session.PROVIDER_CONFIG = "<memcache connection string>"`
+- `queue.TYPE = "memcache"`
+- `queue.CONN_STR = "<memcache connection string>"`
+
+The `memcache` connection string has the scheme `memcache://<memcache service name>:<memcache service port>`, e.g. `gitea-memcached.gitea.svc.cluster.local:11211`.
+The first item here (`<memcache service name>`) will be different compared to the example if you deploy `memcache` yourself.
+
+The above changes are motivated by the idea to tidy dependencies but also have HA-ready ones at the same time.
+The previous `memcache` default was not HA-ready, hence we decided to switch to `redis-cluster` by default.
+
+If you are coming from an existing deployment and [#356](https://gitea.com/gitea/helm-chart/issues/356) is still open, you need to set the config sections for `cache`, `session` and `queue` explicitly:
+
+```yaml
+gitea:
+  config:
+    session:
+      PROVIDER: redis-cluster
+      PROVIDER_CONFIG: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
+
+    cache:
+      ENABLED: true
+      ADAPTER: redis-cluster
+      HOST: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
+
+    queue:
+      TYPE: redis
+      CONN_STR: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
+```

+If you are facing errors like `WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED` due to this automatic transition:
+Have a look at [this discussion](https://gitea.com/gitea/helm-chart/issues/487#issue-220660) and either set `image.rootless: false` or manually update your `~/.ssh/known_hosts` file(s).
+
+<!-- prettier-ignore-start -->
+<!-- markdownlint-disable-next-line -->
+**Transitioning from a RWO to RWX Persistent Volume**
+<!-- prettier-ignore-end -->
+
+If you want to switch to a RWX volume and go for HA, you need to
+
+1. Backup the data stored under `/data`
+2. Let the chart create a new RWX PV (or do it statically yourself)
+3. Restore the backup to the same location in the new PV
+
+<!-- prettier-ignore-start -->
+<!-- markdownlint-disable-next-line -->
+**Transitioning from Postgres to Postgres HA**
+<!-- prettier-ignore-end -->
+
+If you are running with a non-HA PG DB from a previous chart release, you need to set
+
+- `postgresql-ha.enabled=false`
+- `postgresql.enabled=true`
+
+This is needed to stay with your existing single-instance DB (as the HA-variant is the new default).
+
+<!-- prettier-ignore-start -->
+<!-- markdownlint-disable-next-line -->
+**Change of env-to-ini prefix**
+<!-- prettier-ignore-end -->
+
+Before this release, the env-to-ini prefix was `ENV_TO_INI__`.
+This allowed a clear distinction between user-provided and chart-provided env-to-ini variables.
+Due to the removal custom prefix feature in the upstream implementation of env-to-ini, the prefix has been changed to the default `GITEA__`.
+
+If you previously had defined env vars that had the `ENV_TO_INI__` prefix, you need to change them to `GITEA__` in order for them to be picked up by the chart.

+# High Availability
+
+All components (in-memory DB, volume/asset storage, code indexer) used by Gitea must be deployed in a HA-ready fashion to achieve a full HA-ready Gitea deployment.
+The following document explains how to achieve this for all individual components.
+
+The resulting Gitea deployment will consist of ~ 10 pods (depending on the chosen components and their replicas).
+One should evaluate upfront whether a HA-deployment is required as switching between HA/non-HA comes with some effort.
+For production instances, HA is always recommended to increase uptime and have a frictionless update process.
+
+A general comment about chart dependencies and external services:
+Instead of relying on chart dependencies, it is often better to rely on an external, (managed) instances (in-memory database, asset storage provider, database, etc.).
+Many cloud providers offer such services, at least for databases or in-memory databases.
+They might cost a bit more than using a self-hosted k8s variant but are usually easier to maintain and scale, if needed.
+Also they can be centrally managed and are not linked to the Gitea helm chart or namespace.
+Please consider using external services before you start with your Gitea HA setup, it will make your life (and the life of the Gitea maintainers) easier.
+
+This helm chart tries to help as much as possible to simplify and assert the provisioning of a HA-ready Gitea instance by implementing smart conditionals if `replicaCount` is set to a value > 1.
+Nevertheless, we cannot guarantee for every possible combination of Gitea settings to work together perfectly in a HA setup.
+As a general advice, we recommend to have a test environment aside on which to test possible changes/upgrades before applying these to a production installation.
+
+## Requirements for HA
+
+Storage-wise, the HA-Gitea setup requires a RWX file-system which can be shared among the deployment-based replica pods.
+In addition, the following components are required for full HA-readiness:
+
+- A HA-ready issue (and optionally code) indexer: `elasticsearch` or `meilisearch`
+- A HA-ready external object/asset storage (`minio`) (optional, assets can also be stored on the RWX file-system)
+- A HA-ready cache (`redis-cluster`)
+- A HA-ready DB
+
+`postgres.enabled`, which default to `true`, must be set to `false` for a HA setup.
+The default `postgres` chart dependency is not HA-ready (there's a dedicated `postgres-ha` chart).
+
+The following sections discuss each of the components in more detail.
+Note that for each component discussed, the shown configurations only provides a (working) starting point, not necessarily the most optimal setup.
+We try to optimize this document over time as we have gained more experience with HA setups from users.
+
+## Indexers (Issues and code/repo)
+
+The default code indexer `bleve` is not able to allow multiple connections and hence cannot be used in a HA setup.
+Alternatives are `elasticsearch` and `meilisearch` (as of >= 1.19.2).
+Unless you have an existing `elasticsearch` cluster, we recommend using `meilisearch` as it is faster and requires way less resources.
+
+Unfortunately, `meilisearch` does only support the `ISSUE_INDEXER` and not the `REPO_INDEXER` yet ([tracking issue](https://github.com/go-gitea/gitea/pull/24149)).
+This means that the `REPO_INDEXER` must still be disabled for a HA setup right now.
+An alternative to the two options above for the `ISSUE_INDEXER` is `"db"`, however we recommend to just go with `meilisearch` in this case and to not bother the DB with indexing.
+
+To configure `meilisearch` within Gitea, do the following:
+
+```yml
+gitea:
+  config:
+    indexer:
+      ISSUE_INDEXER_CONN_STR: <http://meilisearch.<namespace>.svc.cluster.local:7700>
+      ISSUE_INDEXER_ENABLED: true
+      ISSUE_INDEXER_TYPE: meilisearch
+      REPO_INDEXER_ENABLED: false
+      # REPO_INDEXER_TYPE: meilisearch # not yet working
+```
+
+Unfortunately `meilisearch` cannot be deployed in HA as of now.
+Nevertheless it allows for multiple Gitea requests at the same time and is therefore required in a HA setup.
+
+Exemplary configuration for the [meilisearch-kubernetes](https://github.com/meilisearch/meilisearch-kubernetes/tree/main/charts/meilisearch) chart:
+
+```yaml
+persistence:
+  enabled: true
+  accessMode: ReadWriteOnce
+  size: 5Gi
+```
+
+## Cache, session and queue
+
+A `redis` instance is required for the in-memory cache.
+Two options exist:
+
+- `redis`
+- `redis-cluster`
+
+The chart provides `redis-cluster` as a dependency as this one can be used for both HA and non-HA setups.
+You're also welcome to go with `redis` if you prefer or already have a running instance.
+
+It should be noted that `redis-cluster` support is only available starting with Gitea 1.19.2.
+You can also configure an external (managed) `redis` instance to be used.
+To do so, you need to set the following configuration values yourself:
+
+- `gitea.config.queue.TYPE`: redis`
+- `gitea.config.queue.CONN_STR`: `<your redis connection string>`
+
+- `gitea.config.session.PROVIDER`: `redis`
+- `gitea.config.session.PROVIDER_CONFIG`: `<your redis connection string>`
+
+- `gitea.config.cache.ENABLED`: `true`
+- `gitea.config.cache.ADAPTER`: `redis`
+- `gitea.config.cache.HOST`: `<your redis connection string>`
+
+By default, the `redis-cluster` chart provisions three standalone master nodes of which each has a single replica.
+To reduce the number of pods for a default Gitea deployment, we opted to omit the replicas (`replicas: 0`) by default.
+Only the minimum required number of master pods for a functional `redis-cluster` deployment are provisioned.
+For a "proper" `redis-cluster` setup however, we recommend to set `replicas: 1` and `nodes: 6`.
+
+## Object and asset storage
+
+Object/asset storage refers to the storage of attachments, avatars, LFS files, etc.
+While most of these can be stored on the RWX file-system, it is recommended to use an external S3-compatible object storage for such, mainly for performance reasons.
+
+By default the chart provisions a single RWO volume to store everything (repos, avatars, packages, etc.).
+This volume cannot be mounted by multiple pods.
+Hence, a RWX volume is required and (optionally) an external HA-ready object storage.
+
+> **Note:** Double-check that the file permissions are set correctly on the RWX volume! That is everything should be owned by the `git` user which usually has `uid=1000` and `gid=1000`.
+
+To use `minio` you need to deploy and configure an external `minio` instance yourself and explicitly define the `STORAGE_TYPE` values as shown below.
+
+Note that `MINIO_BUCKET` here is just a name and does not refer to a S3 bucket.
+It's the root access point for all objects belonging to the respective application, i.e., to Gitea in this case.
+
+```yaml
+gitea:
+  config:
+    attachment:
+      STORAGE_TYPE: minio
+    lfs:
+      STORAGE_TYPE: minio
+    picture:
+      AVATAR_STORAGE_TYPE: minio
+    "storage.packages":
+      STORAGE_TYPE: minio
+
+    storage:
+      MINIO_ENDPOINT: <minio-headless.<namespace>.svc.cluster.local:9000>
+      MINIO_LOCATION: <location>
+      MINIO_ACCESS_KEY_ID: <access key>
+      MINIO_SECRET_ACCESS_KEY: <secret key>
+      MINIO_BUCKET: <bucket name>
+      MINIO_USE_SSL: false
+```
+
+Exemplary configuration for the [bitnami minio](https://github.com/bitnami/charts/blob/main/bitnami/minio) chart:
+
+```yaml
+auth:
+  rootUser: minio
+mode: distributed
+replicaCount: 4
+persistence:
+  enabled: true
+  size: 20Gi
+  accessModes:
+    - ReadWriteOnce
+```
+
+## Database
+
+If you do not have an HA-ready DB, using a managed database service in the cloud might be the easiest and most robust solution.
+Remember: disable the built-in `postgres` dependency and configure the database connection manually via `gitea.config.database`:
+
+```yml
+gitea:
+  database:
+    builtIn:
+      postgresql:
+        enabled: false
+  config:
+    database:
+      DB_TYPE: postgres
+      HOST: <host>
+      NAME: <name>
+      USER: <user>
+```
+
+## Known issues
+
+- Currently Cron jobs are run on all replicas as no leader election is implemented.
+  See [https://github.com/go-gitea/gitea/issues/13791](https://github.com/go-gitea/gitea/issues/13791) for a discussion and possible solution.
+
+- Running with multiple replicas slows down Gitea a bit, i.e. page loading time increases.
