# 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.
|
|
|
|
## Introduction
|
|
|
|
This helm chart has taken some inspiration from [jfelten's helm
|
|
chart](https://github.com/jfelten/gitea-helm-chart). But takes a completely
|
|
different approach in providing a database and cache with dependencies.
|
|
Additionally, this chart provides LDAP and admin user configuration with values,
|
|
as well as being deployed as a statefulset to retain stored repositories.
|
|
|
|
## Dependencies
|
|
|
|
Gitea can be run with an external database and cache. This chart provides those
|
|
dependencies, which can be enabled, or disabled via
|
|
[configuration](#configuration).
|
|
|
|
Dependencies:
|
|
|
|
- PostgreSQL
|
|
- Memcached
|
|
- MySQL
|
|
|
|
## Installing
|
|
|
|
```sh
|
|
helm repo add gitea-charts https://dl.gitea.io/charts/
|
|
helm repo update
|
|
helm install gitea gitea-charts/gitea
|
|
```
|
|
|
|
## Prerequisites
|
|
|
|
- Kubernetes 1.12+
|
|
- Helm 3.0+
|
|
- PV provisioner for persistent data support
|
|
|
|
## Chart upgrade to 5.0.0
|
|
|
|
:warning: The most recent `5.0.0` update brings some major and breaking changes.
|
|
Please note the following changes in the Chart to upgrade successfully. :warning:
|
|
|
|
### Enable Dependencies
|
|
|
|
:warning: The values to enable the dependencies,
|
|
such as PostgreSQL, Memcached, MySQL and MariaDB
|
|
have been moved from `gitea.database.builtIn.` to the dependency values. :warning:
|
|
|
|
You can now enable the dependencies as followed:
|
|
|
|
```yaml
|
|
memcached:
|
|
enabled: true
|
|
|
|
postgresql:
|
|
enabled: true
|
|
|
|
mysql:
|
|
enabled: false
|
|
|
|
mariadb:
|
|
enabled: false
|
|
```
|
|
|
|
### App.ini generation
|
|
|
|
The app.ini generation has changed and now utilizes the environment-to-ini
|
|
script provided by newer Gitea versions.
|
|
|
|
> :boom: The Helm Chart now requires Gitea versions of at least 1.11.0.
|
|
|
|
This change ensures, that the app.ini is now persistent.
|
|
|
|
#### Secret Key generation
|
|
|
|
Gitea secret keys (SECRET_KEY, INTERNAL_TOKEN, JWT_SECRET) are now generated
|
|
automatically in certain situations:
|
|
|
|
- New install: By default the secrets are created automatically. If you provide
|
|
secrets via `gitea.config` they will be used instead of automatic generation.
|
|
- Existing installs: The secrets won't be deployed, neither via
|
|
configuration nor via auto generation. We explicitly prevent to set new secrets.
|
|
|
|
> :rotating_light: It would be possible to set new secret keys manually by entering
|
|
the running container and rewriting the app.ini by hand. However, this it is
|
|
not advisable to do so for existing installations. Certain settings like
|
|
_LDAP_ would not be readable anymore.
|
|
|
|
### Probes
|
|
|
|
> :boom: `gitea.customLivenessProbe`, `gitea.customReadinessProbe` and `gitea.customStartupProbe`
|
|
have been removed.
|
|
|
|
They are replaced by the settings `gitea.livenessProbe`, `gitea.readinessProbe`
|
|
and `gitea.startupProbe` which are now fully configurable and used _as-is_ for
|
|
a Chart deployment.
|
|
If you have customized their values instead of using the `custom` prefixed settings,
|
|
please ensure that you remove the `enabled` property from each of them.
|
|
|
|
In case you want to disable one of these probes, let's say the `livenessProbe`, add
|
|
the following to your values. The `podAnnotation` is just there to have a bit more
|
|
context.
|
|
|
|
```diff
|
|
gitea:
|
|
+ livenessProbe:
|
|
podAnnotations: {}
|
|
```
|
|
|
|
### Multiple OAuth and LDAP authentication sources
|
|
|
|
With `5.0.0` of this Chart it is now possible to configure Gitea with multiple
|
|
OAuth and LDAP sources. As a result, you need to update an existing OAuth/LDAP configuration
|
|
in your customized `values.yaml` by replacing the object with settings to a list
|
|
of settings objects. See [OAuth2 Settings](#oauth-settings) and
|
|
[LDAP Settings](#ldap-settings) section for details.
|
|
|
|
## Chart upgrade from 3.x.x to 4.0.0
|
|
|
|
:warning: The most recent `4.0.0` update brings some breaking changes. Please note
|
|
the following changes in the Chart to upgrade successfully. :warning:
|
|
|
|
### Ingress changes
|
|
|
|
To provide a more flexible Ingress configuration we now support not only host
|
|
settings but also provide configuration for the path and pathType. So this
|
|
change changes the hosts from a simple string list, to a list containing a more
|
|
complex object for more configuration.
|
|
|
|
```diff
|
|
ingress:
|
|
enabled: false
|
|
annotations: {}
|
|
# kubernetes.io/ingress.class: nginx
|
|
# kubernetes.io/tls-acme: "true"
|
|
- hosts:
|
|
- - git.example.com
|
|
+ hosts:
|
|
+ - host: git.example.com
|
|
+ paths:
|
|
+ - path: /
|
|
+ pathType: Prefix
|
|
tls: []
|
|
# - secretName: chart-example-tls
|
|
# hosts:
|
|
# - git.example.com
|
|
```
|
|
|
|
If you want everything as it was before, you can simply add the following code
|
|
to all your host entries.
|
|
|
|
```yaml
|
|
paths:
|
|
- path: /
|
|
pathType: Prefix
|
|
```
|
|
|
|
### Dropped kebab-case support
|
|
|
|
In 3.x.x it was possible to provide an ldap configuration via kebab-case, this
|
|
support has now been dropped and only camel case is supported. See [LDAP
|
|
section](#ldap-settings) for more information.
|
|
|
|
### Dependency update
|
|
|
|
The chart comes with multiple databases and Memcached as dependency, the latest
|
|
release updated the dependencies.
|
|
|
|
- Memcached: `4.2.20` -> `5.9.0`
|
|
- PostgreSQL: `9.7.2` -> `10.3.17`
|
|
- MariaDB: `8.0.0` -> `9.3.6`
|
|
|
|
If you're using the builtin databases you will most likely redeploy the chart in
|
|
order to update the database correctly.
|
|
|
|
### Execution of initPreScript
|
|
|
|
Generally spoken, this might not be a breaking change, but it is worth to be
|
|
mentioned.
|
|
|
|
Prior to `4.0.0` only one init container was used to both setup directories and
|
|
configure Gitea. As of now the actual Gitea configuration is separated from the
|
|
other pre-execution. This also includes the execution of _initPreScript_. If you
|
|
have such script, please be aware of this. Dynamically prepare the Gitea setup
|
|
during execution by e.g. adding environment variables to the execution context
|
|
won't work anymore.
|
|
|
|
## Gitea Version 1.14.X repository ROOT
|
|
|
|
Previously the ROOT folder for the Gitea repositories was located at
|
|
`/data/git/gitea-repositories`. In version `1.14` has the path been changed to
|
|
`/data/gitea-repositories`.
|
|
|
|
This chart will set the `gitea.config.repository.ROOT` value default to
|
|
`/data/git/gitea-repositories`.
|
|
|
|
## Configure Commit Signing
|
|
|
|
When using the rootless image the gpg key folder was is not persistent by
|
|
default. If you consider using signed commits for internal Gitea 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
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Gitea Configuration
|
|
|
|
Gitea offers lots of configuration options. 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]:"
|
|
```
|
|
|
|
### Default Configuration
|
|
|
|
This chart will set a few defaults in the Gitea 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 Gitea 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
|
|
```
|
|
|
|
#### Memcached defaults
|
|
|
|
Memcached is handled the exact same way as database builtIn. Once Memcached
|
|
builtIn is enabled, this chart will generate the following part in the `app.ini`:
|
|
|
|
```ini
|
|
[cache]
|
|
ADAPTER = memcache
|
|
ENABLED = true
|
|
HOST = RELEASE-NAME-memcached.default.svc.cluster.local:11211
|
|
```
|
|
|
|
#### 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
|
|
```
|
|
|
|
### Additional _app.ini_ settings
|
|
|
|
> **The [generic](https://docs.gitea.io/en-us/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 containerwhere 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 to
|
|
directly interact 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.
|
|
|
|
Note that the Prefix on this helm chart is `ENV_TO_INI`.
|
|
|
|
For example a database setting needs to have the following
|
|
format:
|
|
|
|
```yaml
|
|
gitea:
|
|
additionalConfigFromEnvs:
|
|
- name: ENV_TO_INI__DATABASE__HOST
|
|
value: my.own.host
|
|
- name: ENV_TO_INI__DATABASE__PASSWD
|
|
valueFrom:
|
|
secretKeyRef:
|
|
name: postgres-secret
|
|
key: password
|
|
```
|
|
|
|
Priority (highest to lowest) for defining app.ini variables:
|
|
|
|
1. Environment variables prefixed with `ENV_TO_INI`
|
|
2. Additional config sources
|
|
3. Values defined in `gitea.config`
|
|
|
|
### External Database
|
|
|
|
An external Database can be used instead of builtIn PostgreSQL or MySQL.
|
|
|
|
```yaml
|
|
gitea:
|
|
config:
|
|
database:
|
|
DB_TYPE: mysql
|
|
HOST: 127.0.0.1:3306
|
|
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
|
|
|
|
This helm chart can use a built in cache. The default is Memcached from bitnami.
|
|
|
|
```yaml
|
|
memcached:
|
|
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.
|
|
|
|
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 storageClass define it as followed:
|
|
|
|
```yaml
|
|
persistence:
|
|
enabled: true
|
|
storageClass: myOwnStorageClass
|
|
```
|
|
|
|
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. You cannot use `admin` as username.
|
|
|
|
```yaml
|
|
gitea:
|
|
admin:
|
|
username: "MyAwesomeGiteaAdmin"
|
|
password: "AReallyAwesomeGiteaPassword"
|
|
email: "gi@tea.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
|
|
```
|
|
|
|
### LDAP Settings
|
|
|
|
Like the admin user the LDAP settings can be updated.
|
|
All LDAP values from <https://docs.gitea.io/en-us/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
|
|
...
|
|
```
|
|
|
|
:warning: Some options are just flags and therefore don't any values. If they
|
|
are defined in `gitea.ldap` configuration, they will be passed to the Gitea 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://docs.gitea.io/en-us/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
|
|
...
|
|
```
|
|
|
|
### 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 Gitea pod.
|
|
|
|
```yaml
|
|
gitea:
|
|
podAnnotations: {}
|
|
```
|
|
|
|

## Local development & testing
|
|
|
|
For local development and testing of pull requests, the following workflow can
|
|
be used:
|
|
|
|
1. Install `minikube` and `helm`.
|
|
2. Start a `minikube` cluster via `minikube start`.
|
|
3. From the `gitea/helm-chart` directory execute the following command. This
|
|
will install the dependencies listed in `Chart.yml` and deploy the current
|
|
state of the helm chart found locally. If you want to test a branch, make
|
|
sure to switch to the respective branch first.
|
|
`helm install --dependency-update gitea . -f values.yaml`.
|
|
4. Gitea is now deployed in `minikube`. To access it, it's port needs to be
|
|
forwarded first from `minikube` to localhost first via `kubectl --namespace
|
|
default port-forward svc/gitea-http 3000:3000`. Now Gitea is accessible at
|
|
[http://localhost:3000](http://localhost:3000).
|
