Upgrade

This document will guide you on how to use the helm upgrade command to upgrade EgressGateway.

Basic command format

helm upgrade [RELEASE] [CHART] [flags]

Here, [RELEASE] represents the application name set during installation, [CHART] refers to the chart, and [flags] can specify additional parameters. To learn more about the parameters for helm upgrade, please refer to the helm upgrade page.

Version upgrade

Follow these steps to perform a version upgrade:

Before upgrading, run the following command to update the local Chart to the latest version:
```
helm repo update
```
View the latest version:
```
helm search repo egressgateway
```

Execute the upgrade command:

helm upgrade \
  egress \
  egressgateway/egressgateway \
  --reuse-values \
  --version [version]

Replace [version] with the version you want to update.

Configuration upgrade

Follow these steps to perform a configuration upgrade:

To view the available values parameters, visit the values documentation.
Update the configuration using the --set flags. The following example shows how to change the egress agent log level to debug level. By using the --reuse-values parameter, you can reuse the values from the previous release and merge any overrides from the command line.
```
helm upgrade \
  egress \
  egressgateway/egressgateway \
  --set agent.debug.logLevel=debug \
  --reuse-values
```
