Introduction

This Helm chart is based on the Gitea 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://codeberg.org/forgejo-contrib/-/packages/container/forgejo/0.8.0 or in the repository 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 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)
• Redis-Cluster (Bitnami Redis-Cluster)

Non-HA Dependencies

Alternatively, the following non-HA replacements are available:

• PostgreSQL (Bitnami PostgreSQL)

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.

Please double-check the image repository and available tags in the sub-chart:

• PostgreSQL-HA
• PostgreSQL
• Redis Cluster

and look up the image tag which fits your needs on Dockerhub.

Installing

helm install forgejo oci://codeberg.org/forgejo-contrib/forgejo

In case you want to supply values, you can reference a values.yaml file:

helm install forgejo -f values.yaml oci://codeberg.org/forgejo-contrib/forgejo

When upgrading, please refer to the 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 document for more details.

Configuration

Forgejo offers lots of configuration options. Every value described in the Cheat Sheet can be set as a Helm value. Configuration sections map to (lowercased) YAML blocks, while the keys themselves remain in all caps.

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:

[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.

[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.

[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 template inside (init-)container "env" declarations

• START_SSH_SERVER: true (Unless explicity overwritten by gitea.config.server.START_SSH_SERVER)

  see _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 in gitea.inline_configuration.defaults.server definition

• SSH_LOG_LEVEL environment variable is not injected into the container

  see 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):

   values.yml

   redis-cluster:
     enabled: false
   postgresql:
     enabled: true
   postgresql-ha:
     enabled: false
   
   persistence:
     enabled: true
   
   gitea:
     config:
       database:
         DB_TYPE: postgres
       session:
         PROVIDER: db
       cache:
         ADAPTER: memory
       queue:
         TYPE: level
       indexer:
         ISSUE_INDEXER_TYPE: bleve
         REPO_INDEXER_ENABLED: true
   

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.

   values.yml

   redis-cluster:
     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
   

Additional app.ini settings

The generic 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.

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.

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.

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:

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 page.

Environment variables need to be prefixed with FORGEJO.

For example a database setting needs to have the following format:

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

2. Additional config sources

3. Values defined in gitea.config

External Database

A supported external databasecan 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.

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:

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:

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.

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:

$ 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.

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.

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:

persistence:
  enabled: true
  storageClass: myOwnStorageClass

If you want to manage your own PVC you can simply pass the PVC name to the chart.

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:

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.

gitea:
  admin:
    username: 'MyAwesomeForgejoAdmin'
    password: 'AReallyAwesomeForgejoPassword'
    email: 'forge@jo.com'

You can also use an existing Secret to configure the admin user:

apiVersion: v1
kind: Secret
metadata:
  name: gitea-admin-secret
type: Opaque
stringData:
  username: MyAwesomeGiteaAdmin
  password: AReallyAwesomeGiteaPassword

gitea:
  admin:
    existingSecret: gitea-admin-secret

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.

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:

apiVersion: v1
kind: Secret
metadata:
  name: gitea-ldap-secret
type: Opaque
stringData:
  bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
  bindPassword: JustAnotherBindPw

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, are available.

Multiple OAuth2 sources can be configured with additional OAuth list items.

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:

apiVersion: v1
kind: Secret
metadata:
  name: gitea-oauth-secret
type: Opaque
stringData:
  key: hello
  secret: world

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, 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.

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.

apiVersion: v1
kind: Secret
metadata:
  name: custom-gitea-gpg-key
type: Opaque
stringData:
  privateKey: |-
    -----BEGIN PGP PRIVATE KEY BLOCK-----
    ...
    -----END PGP PRIVATE KEY BLOCK-----    

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.

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.

gitea:
  metrics:
    enabled: true
    serviceMonitor:
      enabled: true

  config:
    server:
      ENABLE_PPROF: true

Pod annotations

Annotations can be added to the Forgejo pod.

gitea:
  podAnnotations: {}

Themes

Custom themes can be added via k8s secrets and referencing them in values.yaml.

The http provider is useful here.

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:

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:

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 is required. Here's an examplary values.yml definition which makes use of a digest:

image:
  registry: codeberg.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:

"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": "codeberg.org/{{depName}}",
    "autoReplaceStringTemplate": "{{depName}}\n{{indentation}}tag: {{newValue}}\n{{indentation}}digest: {{#if newDigest}}{{{newDigest}}}{{else}}{{{currentDigest}}}{{/if}}"
  }
]
