[Forgejo](https://forgejo.org/) is a community managed lightweight code hosting solution written in Go.
It is published under the MIT license.
## Introduction
This Helm chart is based on the [Gitea chart](https://gitea.com/gitea/helm-chart).
Yet it takes a completely different approach in providing a database and cache with dependencies.
Additionally, this chart allows to provide LDAP and admin user configuration with values.
## Update and versioning policy
The Forgejo helm chart versioning does not follow Forgejo's versioning.
The latest chart version can be looked up in <https://code.forgejo.org/forgejo-helm/-/packages/container/forgejo> or in the [repository releases](https://code.forgejo.org/forgejo-helm/forgejo-helm/releases).
The chart aims to follow Forgejo's releases closely.
There might be times when the chart is behind the latest Forgejo release.
This might be caused by different reasons, most often due to time constraints of the maintainers (remember, all work here is done voluntarily in the spare time of people).
If you're eager to use the latest Forgejo version earlier than this chart catches up, then change the tag in `values.yaml` to the latest Forgejo version.
This is due to Forgejo not strictly following [semantic versioning](https://semver.org/#summary) as breaking changes do not increase the major version.
I.e., "minor" version bumps are considered "major".
Yet most often no issues will be encountered and the chart maintainers aim to communicate early/upfront if this would be the case.
## Dependencies
Forgejo can be run with an external database and cache.
This chart provides those dependencies, which can be enabled, or disabled via configuration.
### HA Dependencies
These dependencies are enabled by default:
- PostgreSQL HA ([Bitnami PostgreSQL-HA](https://github.com/bitnami/charts/blob/main/bitnami/postgresql-ha/Chart.yaml))
- Redis-Cluster ([Bitnami Redis-Cluster](https://github.com/bitnami/charts/blob/main/bitnami/redis-cluster/Chart.yaml))
### Non-HA Dependencies
Alternatively, the following non-HA replacements are available:
- PostgreSQL ([Bitnami PostgreSQL](https://github.com/bitnami/charts/blob/main/bitnami/postgresql/Chart.yaml))
- Redis ([Bitnami Redis](https://github.com/bitnami/charts/blob/main/bitnami/redis/Chart.yaml))
### Dependency Versioning
Updates of sub-charts will be incorporated into the Gitea chart as they are released.
The reasoning behind this is that new users of the chart will start with the most recent sub-chart dependency versions.
**Note** If you want to stay on an older appVersion of a sub-chart dependency (e.g. PostgreSQL), you need to override the image tag in your `values.yaml` file.
In fact, we recommend to do so right from the start to be independent of major sub-chart dependency changes as they are released.
There is no need to update to every new PostgreSQL major version - you can happily skip some and do larger updates when you are ready for them.
We recommend to use a rolling tag like `:<majorVersion>-debian-<debian major version>` to incorporate minor and patch updates for the respective major version as they are released.
Alternatively you can also use a versioning helper tool like [renovate](https://github.com/renovatebot/renovate).
Please double-check the image repository and available tags in the sub-chart:
- [PostgreSQL-HA](https://hub.docker.com/r/bitnami/postgresql-repmgr/tags)
- [PostgreSQL](https://hub.docker.com/r/bitnami/postgresql/tags)
- [Redis Cluster](https://hub.docker.com/r/bitnami/redis-cluster/tags)
- [Redis](https://hub.docker.com/r/bitnami/redis/tags)
and look up the image tag which fits your needs on Dockerhub.
## Installing
```sh
helm install forgejo oci://code.forgejo.org/forgejo-helm/forgejo
```
In case you want to supply values, you can reference a `values.yaml` file:
```sh
helm install forgejo -f values.yaml oci://code.forgejo.org/forgejo-helm/forgejo
```
When upgrading, please refer to the [Upgrading](#upgrading) section at the bottom of this document for major and breaking changes.
## High Availability
This chart supports running Forgejo and it's dependencies in HA mode.
Care must be taken for production use as not all implementation details of Forgejo core are officially HA-ready yet.
Deploying a HA-ready Forgejo instance requires some effort including using HA-ready dependencies.
See the [HA Setup](docs/ha-setup.md) document for more details.
## Configuration
Forgejo offers lots of configuration options.
Every value described in the [Cheat Sheet](https://forgejo.org/docs/latest/admin/config-cheat-sheet/) can be set as a Helm value.
Configuration sections map to (lowercased) YAML blocks, while the keys themselves remain in all caps.
```yaml
gitea:
config:
# values in the DEFAULT section
# (https://forgejo.org/docs/latest/admin/config-cheat-sheet/#overall-default)
# are un-namespaced
#
APP_NAME: 'Forgejo: Git with a cup of tea'
#
# https://forgejo.org/docs/latest/admin/config-cheat-sheet/#repository-repository
repository:
ROOT: '~/gitea-repositories'
#
# https://forgejo.org/docs/latest/admin/config-cheat-sheet/#repository---pull-request-repositorypull-request
repository.pull-request:
WORK_IN_PROGRESS_PREFIXES: 'WIP:,[WIP]:'
```
### Default Configuration
This chart will set a few defaults in the Forgejo configuration based on the service and ingress settings.
All defaults can be overwritten in `gitea.config`.
INSTALL_LOCK is always set to true, since we want to configure Forgejo with this helm chart and everything is taken care of.
_All default settings are made directly in the generated `app.ini`, not in the Values._
#### Database defaults
If a builtIn database is enabled the database configuration is set automatically.
For example, PostgreSQL builtIn will appear in the `app.ini` as:
```ini
[database]
DB_TYPE = postgres
HOST = RELEASE-NAME-postgresql.default.svc.cluster.local:5432
NAME = gitea
PASSWD = gitea
USER = gitea
```
#### Server defaults
The server defaults are a bit more complex.
If ingress is `enabled`, the `ROOT_URL`, `DOMAIN` and `SSH_DOMAIN` will be set accordingly.
`HTTP_PORT` always defaults to `3000` as well as `SSH_PORT` to `22`.
```ini
[server]
APP_DATA_PATH = /data
DOMAIN = git.example.com
HTTP_PORT = 3000
PROTOCOL = http
ROOT_URL = http://git.example.com
SSH_DOMAIN = git.example.com
SSH_LISTEN_PORT = 22
SSH_PORT = 22
ENABLE_PPROF = false
```
#### Metrics defaults
The Prometheus `/metrics` endpoint is disabled by default.
```ini
[metrics]
ENABLED = false
```
#### Rootless Defaults
If `.Values.image.rootless: true`, then the following will occur. In case you use `.Values.image.fullOverride`, check that this works in your image:
- `$HOME` becomes `/data/gitea/git`
[see deployment.yaml](./templates/gitea/deployment.yaml) template inside (init-)container "env" declarations
- `START_SSH_SERVER: true` (Unless explicity overwritten by `gitea.config.server.START_SSH_SERVER`)
[see \_helpers.tpl](./templates/_helpers.tpl) in `gitea.inline_configuration.defaults.server` definition
- `SSH_LISTEN_PORT: 2222` (Unless explicity overwritten by `gitea.config.server.SSH_LISTEN_PORT`)
[see \_helpers.tpl](./templates/_helpers.tpl) in `gitea.inline_configuration.defaults.server` definition
- `SSH_LOG_LEVEL` environment variable is not injected into the container
[see deployment.yaml](./templates/gitea/deployment.yaml) template inside container "env" declarations
#### Session, Cache and Queue
The session, cache and queue settings are set to use the built-in Redis Cluster sub-chart dependency.
If Redis Cluster is disabled, the chart will fall back to the Gitea defaults which use "memory" for `session` and `cache` and "level" for `queue`.
While these will work and even not cause immediate issues after startup, **they are not recommended for production use**.
Reasons being that a single pod will take on all the work for `session` and `cache` tasks in its available memory.
It is likely that the pod will run out of memory or will face substantial memory spikes, depending on the workload.
External tools such as `redis-cluster` or `memcached` handle these workloads much better.
### Single-Pod Configurations
If HA is not needed/desired, the following configurations can be used to deploy a single-pod Forgejo instance.
1. For a production-ready single-pod Forgejo instance without external dependencies (using the chart dependency `postgresql` and `redis`):
<details>
<summary>values.yml</summary>
```yaml
redis-cluster:
enabled: false
redis:
enabled: true
postgresql:
enabled: true
postgresql-ha:
enabled: false
persistence:
enabled: true
gitea:
config:
database:
DB_TYPE: postgres
indexer:
ISSUE_INDEXER_TYPE: bleve
REPO_INDEXER_ENABLED: true
```
</details>
2. For a minimal DEV installation (using the built-in sqlite DB instead of Postgres):
This will result in a single-pod Forgejo instance _without any dependencies and persistence_.
**Do not use this configuration for production use**.
<details>
<summary>values.yml</summary>
```yaml
redis-cluster:
enabled: false
redis:
enabled: false
postgresql:
enabled: false
postgresql-ha:
enabled: false
persistence:
enabled: false
gitea:
config:
database:
DB_TYPE: sqlite3
session:
PROVIDER: memory
cache:
ADAPTER: memory
queue:
TYPE: level
```
</details>
### Additional _app.ini_ settings
> **The [generic](https://forgejo.org/docs/latest/admin/config-cheat-sheet/#overall-default)
> section cannot be defined that way.**
Some settings inside _app.ini_ (like passwords or whole authentication configurations) must be considered sensitive and therefore should not be passed via plain text inside the _values.yaml_ file.
In times of _GitOps_ the values.yaml could be stored in a Git repository where sensitive data should never be accessible.
The Helm Chart supports this approach and let the user define custom sources like
Kubernetes Secrets to be loaded as environment variables during _app.ini_ creation or update.
```yaml
gitea:
additionalConfigSources:
- secret:
secretName: gitea-app-ini-oauth
- configMap:
name: gitea-app-ini-plaintext
```
This would mount the two additional volumes (`oauth` and `some-additionals`) from different sources to the init container where the _app.ini_ gets updated.
All files mounted that way will be read and converted to environment variables and then added to the _app.ini_ using [environment-to-ini](https://github.com/go-gitea/gitea/tree/main/contrib/environment-to-ini).
The key of such additional source represents the section inside the _app.ini_.
The value for each key can be multiline ini-like definitions.
In example, the referenced `gitea-app-ini-plaintext` could look like this.
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: gitea-app-ini-plaintext
data:
session: |
PROVIDER=memory
SAME_SITE=strict
cron.archive_cleanup: |
ENABLED=true
```
Or when using a Kubernetes secret, having the same data structure:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-security-related-configuration
type: Opaque
stringData:
security: |
PASSWORD_COMPLEXITY=off
session: |
SAME_SITE=strict
```
#### User defined environment variables in app.ini
Users are able to define their own environment variables, which are loaded into the containers.
We also support interacting directly with the generated _app.ini_.
To inject self defined variables into the _app.ini_ a certain format needs to be honored.
This is described in detail on the [env-to-ini](https://github.com/go-gitea/gitea/tree/main/contrib/environment-to-ini) page.
Environment variables need to be prefixed with `FORGEJO`.
For example a database setting needs to have the following format:
```yaml
gitea:
config:
database:
HOST: my.own.host
additionalConfigFromEnvs:
- name: FORGEJO__DATABASE__PASSWD
valueFrom:
secretKeyRef:
name: postgres-secret
key: password
```
Priority (highest to lowest) for defining app.ini variables:
1. Environment variables prefixed with `FORGEJO`
1. Additional config sources
1. Values defined in `gitea.config`
### External Database
A [supported external database](https://forgejo.org/docs/latest/admin/config-cheat-sheet/#database-database/)can be used instead of the built-in PostgreSQL.
In fact, it is **highly recommended** to use an external database to ensure a stable Forgejo installation longterm.
If an external database is used, no matter which type, make sure to set `postgresql.enabled` to `false` to disable the use of the built-in PostgreSQL.
```yaml
gitea:
config:
database:
DB_TYPE: mysql # supported values are mysql, postgres, mssql, sqlite3
HOST: <mysql HOST>
NAME: gitea
USER: root
PASSWD: gitea
SCHEMA: gitea
postgresql:
enabled: false
```
### Ports and external url
By default port `3000` is used for web traffic and `22` for ssh.
Those can be changed:
```yaml
service:
http:
port: 3000
ssh:
port: 22
```
This helm chart automatically configures the clone urls to use the correct ports.
You can change these ports by hand using the `gitea.config` dict.
However you should know what you're doing.
### ClusterIP
By default the `clusterIP` will be set to `None`, which is the default for headless services.
However if you want to omit the clusterIP field in the service, use the following values:
```yaml
service:
http:
type: ClusterIP
port: 3000
clusterIP:
ssh:
type: ClusterIP
port: 22
clusterIP:
```
### SSH and Ingress
If you're using ingress and want to use SSH, keep in mind, that ingress is not able to forward SSH Ports.
You will need a LoadBalancer like `metallb` and a setting in your ssh service annotations.
```yaml
service:
ssh:
annotations:
metallb.universe.tf/allow-shared-ip: test
```
### SSH on crio based kubernetes cluster
If you use `crio` as container runtime it is not possible to read from a remote repository.
You should get an error message like this:
```bash
$ git clone git@k8s-demo.internal:admin/test.git
Cloning into 'test'...
Connection reset by 192.168.179.217 port 22
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
```
To solve this problem add the capability `SYS_CHROOT` to the `securityContext`.
More about this issue [here](https://gitea.com/gitea/helm-chart/issues/161).
### Cache
The cache handling is done via `redis-cluster` (via the `bitnami` chart) by default.
This deployment is HA-ready but can also be used for single-pod deployments.
By default, 6 replicas are deployed for a working `redis-cluster` deployment.
Many cloud providers offer a managed redis service, which can be used instead of the built-in `redis-cluster`.
```yaml
redis-cluster:
enabled: true
```
### Persistence
Forgejo will be deployed as a deployment.
By simply enabling the persistence and setting the storage class according to your cluster everything else will be taken care of.
The following example will create a PVC as a part of the deployment.
Please note, that an empty `storageClass` in the persistence will result in kubernetes using your default storage class.
If you want to use your own storage class define it as follows:
```yaml
persistence:
enabled: true
storageClass: myOwnStorageClass
```
If you want to manage your own PVC you can simply pass the PVC name to the chart.
```yaml
persistence:
enabled: true
claimName: MyAwesomeGiteaClaim
```
In case that persistence has been disabled it will simply use an empty dir volume.
PostgreSQL handles the persistence in the exact same way.
You can interact with the postgres settings as displayed in the following example:
```yaml
postgresql:
persistence:
enabled: true
claimName: MyAwesomeGiteaPostgresClaim
```
### Admin User
This chart enables you to create a default admin user.
It is also possible to update the password for this user by upgrading or redeploying the chart.
It is not possible to delete an admin user after it has been created.
This has to be done in the ui.
You cannot use `admin` as username.
```yaml
gitea:
admin:
username: 'MyAwesomeForgejoAdmin'
password: 'AReallyAwesomeForgejoPassword'
email: 'forge@jo.com'
```
You can also use an existing Secret to configure the admin user:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-admin-secret
type: Opaque
stringData:
username: MyAwesomeGiteaAdmin
password: AReallyAwesomeGiteaPassword
```
```yaml
gitea:
admin:
existingSecret: gitea-admin-secret
```
Whether you use the existing Secret or specify a user name and password, there are three modes for how the admin user password is created or set.
- `keepUpdated` (the default) will set the admin user password, and reset it to the defined value every time the pod is recreated.
- `initialOnlyNoReset` will set the admin user password when creating it, but never try to update the password.
- `initialOnlyRequireReset` will set the admin user password when creating it, never update it, and require that the password be changed at the initial login.
These modes can be set like the following:
```yaml
gitea:
admin:
passwordMode: initialOnlyRequireReset
```
### LDAP Settings
Like the admin user the LDAP settings can be updated.
All LDAP values from <https://forgejo.org/docs/latest/admin/command-line/#admin> are available.
Multiple LDAP sources can be configured with additional LDAP list items.
```yaml
gitea:
ldap:
- name: MyAwesomeGiteaLdap
securityProtocol: unencrypted
host: '127.0.0.1'
port: '389'
userSearchBase: ou=Users,dc=example,dc=com
userFilter: sAMAccountName=%s
adminFilter: CN=Admin,CN=Group,DC=example,DC=com
emailAttribute: mail
bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
bindPassword: JustAnotherBindPw
usernameAttribute: CN
publicSSHKeyAttribute: publicSSHKey
```
You can also use an existing secret to set the `bindDn` and `bindPassword`:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-ldap-secret
type: Opaque
stringData:
bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
bindPassword: JustAnotherBindPw
```
```yaml
gitea:
ldap:
- existingSecret: gitea-ldap-secret
```
⚠️ Some options are just flags and therefore don't have any values.
If they are defined in `gitea.ldap` configuration, they will be passed to the Forgejo CLI without any value.
Affected options:
- notActive
- skipTlsVerify
- allowDeactivateAll
- synchronizeUsers
- attributesInBind
### OAuth2 Settings
Like the admin user, OAuth2 settings can be updated and disabled but not deleted.
Deleting OAuth2 settings has to be done in the UI.
All OAuth2 values, which are documented [here](https://forgejo.org/docs/latest/admin/command-line/#admin), are available.
Multiple OAuth2 sources can be configured with additional OAuth list items.
```yaml
gitea:
oauth:
- name: 'MyAwesomeGiteaOAuth'
provider: 'openidConnect'
key: 'hello'
secret: 'world'
autoDiscoverUrl: 'https://gitea.example.com/.well-known/openid-configuration'
#useCustomUrls:
#customAuthUrl:
#customTokenUrl:
#customProfileUrl:
#customEmailUrl:
```
You can also use an existing secret to set the `key` and `secret`:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: gitea-oauth-secret
type: Opaque
stringData:
key: hello
secret: world
```
```yaml
gitea:
oauth:
- name: 'MyAwesomeGiteaOAuth'
existingSecret: gitea-oauth-secret
```
## Configure commit signing
When using the rootless image the gpg key folder is not persistent by default.
If you consider using signed commits for internal Forgejo activities (e.g. initial commit), you'd need to provide a signing key.
Prior to [PR186](https://gitea.com/gitea/helm-chart/pulls/186), imported keys had to be re-imported once the container got replaced by another.
The mentioned PR introduced a new configuration object `signing` allowing you to configure prerequisites for commit signing.
By default this section is disabled to maintain backwards compatibility.
```yaml
signing:
enabled: false
gpgHome: /data/git/.gnupg
```
Regardless of the used container image the `signing` object allows to specify a private gpg key.
Either using the `signing.privateKey` to define the key inline, or refer to an existing secret containing the key data by using `signing.existingSecret`.
```yaml
apiVersion: v1
kind: Secret
metadata:
name: custom-gitea-gpg-key
type: Opaque
stringData:
privateKey: |-
-----BEGIN PGP PRIVATE KEY BLOCK-----
...
-----END PGP PRIVATE KEY BLOCK-----
```
```yaml
signing:
existingSecret: custom-gitea-gpg-key
```
To use the gpg key, Forgejo needs to be configured accordingly.
A detailed description can be found in the [documentation](https://forgejo.org/docs/latest/admin/signing/#general-configuration).
## Metrics and profiling
A Prometheus `/metrics` endpoint on the `HTTP_PORT` and `pprof` profiling endpoints on port 6060 can be enabled under `gitea`.
Beware that the metrics endpoint is exposed via the ingress, manage access using ingress annotations for example.
To deploy the `ServiceMonitor`, you first need to ensure that you have deployed `prometheus-operator` and its [CRDs](https://github.com/prometheus-operator/prometheus-operator#customresourcedefinitions).
```yaml
gitea:
metrics:
enabled: true
serviceMonitor:
enabled: true
config:
server:
ENABLE_PPROF: true
```
## Pod annotations
Annotations can be added to the Forgejo pod.
```yaml
gitea:
podAnnotations: {}
```
## Themes
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.
```yaml
extraVolumes:
- name: gitea-themes
secret:
secretName: gitea-themes
extraVolumeMounts:
- name: gitea-themes
readOnly: true
mountPath: '/data/gitea/public/assets/css'
```
The secret can be created via `terraform`:
```hcl
resource "kubernetes_secret" "gitea-themes" {
metadata {
name = "gitea-themes"
namespace = "gitea"
}
data = {
"my-theme.css" = data.http.gitea-theme-light.body
"my-theme-dark.css" = data.http.gitea-theme-dark.body
"my-theme-auto.css" = data.http.gitea-theme-auto.body
}
type = "Opaque"
}
data "http" "gitea-theme-light" {
url = "<raw theme url>"
request_headers = {
Accept = "application/json"
}
}
data "http" "gitea-theme-dark" {
url = "<raw theme url>"
request_headers = {
Accept = "application/json"
}
}
data "http" "gitea-theme-auto" {
url = "<raw theme url>"
request_headers = {
Accept = "application/json"
}
}
```
or natively via `kubectl`:
```bash
kubectl create secret generic gitea-themes --from-file={{FULL-PATH-TO-CSS}} --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:
registry: code.forgejo.org
repository: forgejo/forgejo
tag: 1.20.2-0
digest: sha256:f597c14a403c2fdee9a62dae8bae29d6442f7b2cc85872cc9bb535a24cb1630e
```
By default Renovate adds digest after the `tag`.
To comply with the Forgejo 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"],
"matchStrings": ["(?<depName>forgejo\\/forgejo)\\n(?<indentation>\\s+)tag: (?<currentValue>[^@].*?)\\n\\s+digest: (?<currentDigest>sha256:[a-f0-9]+)"],
"datasourceTemplate": "docker",
"packageNameTemplate": "code.forgejo.org/{{depName}}",
"autoReplaceStringTemplate": "{{depName}}\n{{indentation}}tag: {{newValue}}\n{{indentation}}digest: {{#if newDigest}}{{{newDigest}}}{{else}}{{{currentDigest}}}{{/if}}"
}
]
```

## Upgrading
This section lists major and breaking changes of each Helm Chart version.
Please read them carefully to upgrade successfully, especially the change of the **default database backend**!
If you miss this, blindly upgrading may delete your Postgres instance and you may lose your data!
### To v8.0.0
You need Forgejo v8+ to use this Helm Chart version.
Use the v7 Helm Chart for Forgejo v7.
### To v7.0.0
The Forgejo docker image is pulled from `code.forgejo.org` instead of `codeberg.org`.
### To v6.0.0
You need Forgejo v7+ to use this Helm Chart version.
Use the v5 Helm Chart for Forgejo v1.21.
