# Helm Chart
## Requirement
- redis (optional, if you need persistence)
- docker image (you can use the image from docker hub or build one by yourself)
## Install
2021-12-27 16:09:48 +00:00
If you need redis:
```sh
helm repo add bitnami https://charts.bitnami.com/bitnami
helm install redis bitnami/redis
```
To get the dynamically generated redis password, you can use the following command:
```sh
export REDIS_PASSWORD=$(kubectl get secret --namespace bbgo redis -o jsonpath="{.data.redis-password}" | base64 --decode)
```
Prepare your docker image locally (you can also use the docker image from docker hub):
```sh
make docker DOCKER_TAG=1.16.0
```
The docker tag version number is from the file [Chart.yaml](charts/bbgo/Chart.yaml)
Choose your instance name:
```sh
export INSTANCE=grid
```
Prepare your secret:
```sh
kubectl create secret generic bbgo-$INSTANCE --from-env-file .env.local
```
Configure your config file, the chart defaults to read config/bbgo.yaml to create a configmap:
```sh
cp config/grid.yaml bbgo-$INSTANCE.yaml
vim bbgo-$INSTANCE.yaml
```
Prepare your configmap:
```sh
kubectl create configmap bbgo-$INSTANCE --from-file=bbgo.yaml=bbgo-$INSTANCE.yaml
```
Install chart with the preferred release name, the release name maps to the previous secret we just created, that
is, `bbgo-grid`:
```sh
helm install bbgo-$INSTANCE ./charts/bbgo
```
By default, the helm chart uses configmap and dotenv secret by the release name,
if you have an existing configmap that is not named `bbgo-$INSTANCE`, you can specify the configmap via
the `existingConfigmap` option:
```sh
helm install --set existingConfigmap=bbgo-$INSTANCE bbgo-$INSTANCE ./charts/bbgo
```
To use the latest version:
```sh
helm install --set existingConfigmap=bbgo-$INSTANCE --set image.tag=latest bbgo-$INSTANCE ./charts/bbgo
```

Or, if you have custom values.yaml to override the default values:
```sh
helm install --values deploy/my-bbgo-values.yaml bbgo-$INSTANCE ./charts/bbgo
```
2021-12-27 16:09:48 +00:00
To upgrade:
```sh
helm upgrade bbgo-$INSTANCE ./charts/bbgo
helm upgrade --set image.tag=1.15.2 bbgo-$INSTANCE ./charts/bbgo
```

## Delete an installed chart
2021-12-27 16:09:48 +00:00
```sh
helm delete bbgo-$INSTANCE
```
