# Gitea Helm Chart
|
|
|
|
[Gitea](https://gitea.io/en-us/) is a community managed lightweight code hosting solution written in Go. It is published under the MIT license.
|
|
|
|
Readme will be updated with examples in the next few days
|
|
|
|
## Introduction
|
|
|
|
This helm chart has taken some inspiration from https://github.com/jfelten/gitea-helm-chart
|
|
But takes a completly different approach in providing database and cache with dependencies.
|
|
Also this chart provides ldap and admin user configuration with values as well as it is deployed as statefulset to retain stored repositories.
|
|
|
|
## Dependencies
|
|
|
|
Gitea can be run with external database and cache. This chart provides those dependencies, which can be
|
|
enabled, or disabled via [configuration](#configuration).
|
|
|
|
Dependencies:
|
|
|
|
* Postgresql
|
|
* Memcached
|
|
* Mysql
|
|
|
|
## Installing
|
|
|
|
```
|
|
helm repo add novum-rgi-helm https://novumrgi.github.io/helm/
|
|
helm install gitea novum-rgi-helm/gitea
|
|
```
|
|
|
|
## Prerequisites
|
|
|
|
* Kubernetes 1.12+
|
|
* Helm 3.0+
|
|
* PV provisioner for persistent data support
|
|
|
|
## Examples
|
|
|
|
### Gitea Configuration
|
|
|
|
Gitea offers lots of configuration. This is fully described in the [Gitea Cheat Sheet](https://docs.gitea.io/en-us/config-cheat-sheet/).
|
|
|
|
```yaml
|
|
gitea:
|
|
config:
|
|
APP_NAME: "Gitea: With a cup of tea."
|
|
repository:
|
|
ROOT: "~/gitea-repositories"
|
|
repository.pull-request:
|
|
WORK_IN_PROGRESS_PREFIXES: "WIP:,[WIP]:"
|
|
```
|
|
|
|
### 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 helmchart 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.
|
|
|
|
### Cache
|
|
|
|
This helm chart can use a built in cache. The default is memcached from bitnami.
|
|
|
|
```yaml
|
|
gitea:
|
|
cache:
|
|
builtIn:
|
|
enabled: true
|
|
```
|
|
|
|
If the built in cache should not be used simply configure the cache in gitea.config
|
|
|
|
```yaml
|
|
gitea:
|
|
config:
|
|
cache:
|
|
ENABLED: true
|
|
ADAPTER: memory
|
|
INTERVAL: 60
|
|
HOST: 127.0.0.1:9090
|
|
```
|
|
### Persistence
|
|
|
|
Gitea will be deployed as a statefulset. 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 statefulset. This PVC will not be deleted
|
|
even if you uninstall the chart.
|
|
When using Postgresql as dependency, this will also be deployed as a statefulset by default.
|
|
|
|
If you want to manage your own PVC you can simply pass the PVC name to the chart.
|
|
|
|
```yaml
|
|
persistence:
|
|
enabled: true
|
|
existingClaim: MyAwesomeGiteaClaim
|
|
```
|
|
|
|
In case that peristence 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
|
|
existingClaim: MyAwesomeGiteaPostgresClaim
|
|
```
|
|
|
|
Mysql also handles persistence the same, even though it is not deployed as a statefulset.
|
|
You can interact with the postgres settings as displayed in the following example:
|
|
|
|
```yaml
|
|
mysql:
|
|
persistence:
|
|
enabled: true
|
|
existingClaim: MyAwesomeGiteaMysqlClaim
|
|
```
|
|
|
|
### 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 redeloying the chart.
|
|
It is not possible to delete an admin user after it has been created. This has to be done in the ui.
|
|
|
|
```yaml
|
|
gitea:
|
|
admin:
|
|
username: "MyAwesomeGiteaAdmin"
|
|
password: "AReallyAwesomeGiteaPassword"
|
|
email: "gi@tea.com"
|
|
```
|
|
|
|
### LDAP Settings
|
|
|
|
Like the admin user the ldap settings can be updated but also disabled or deleted.
|
|
|
|
```yaml
|
|
gitea:
|
|
ldap:
|
|
enabled: true
|
|
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
|
|
```
|
|
|
|
