## Deploy to Kubernetes with Helm
169+
The chatgpt-bot-chart deploys a containerized chatgpt-bot instance which will connect to a running mattermost container in the same kubernetes cluster. Chart uses 'mattermost-team-edition' and the 'mattermost' namespace by default. Uses environment variables MATTERMOST_TOKEN and OPENAI_API_KEY.
170+
```bash
171+
helm upgrade chatgpt-bot ./helm/chatgpt-bot-chart \
172+
--create-namespace \
173+
--install \
174+
-n mattermost \
175+
-f ./helm/chatgpt-bot-chart/values.yaml \
176+
--set chatbot.mattermostToken="$MATTERMOST_TOKEN" \
177+
--set chatbot.openaiApiKey="$OPENAI_API_KEY"
178+
```

description: A Helm chart for Kubernetes

# A chart can be either an 'application' or a 'library' chart.
6+
#
7+
# Application charts are a collection of templates that can be packaged into versioned archives
8+
# to be deployed.
9+
#
10+
# Library charts provide useful utilities or functions for the chart developer. They're included as
11+
# a dependency of application charts to inject those utilities and functions into the rendering
12+
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
13+
type: application
14+
15+
# This is the chart version. This version number should be incremented each time you make changes
16+
# to the chart and its templates, including the app version.
17+
# Versions are expected to follow Semantic Versioning (https://semver.org/)
18+
version: 0.1.0
19+
20+
# This is the version number of the application being deployed. This version number should be
21+
# incremented each time you make changes to the application. Versions are not expected to
22+
# follow Semantic Versioning. They should reflect the version the application is using.
23+
# It is recommended to use it with quotes.
