Dokku ships with default charts and customizes their helm values. In certain cases, it may be useful to further customize those values to better support specific installations. With this change, it is now possible to set custom values by providing the key in the format `chart.$CHART_NAME.$PROPERTY`. For instance, to increase timeouts for the keda http addon: ```shell dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.tcpConnectTimeout 120s dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.keepAlive 120s dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.responseHeaderTimeout 120s dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.idleConnTimeout 120s dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.tlsHandshakeTimeout 120s dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.expectContinueTimeout 120s ``` To reset a value to its default, simply set the value to an empty string. ```shell dokku scheduler-k3s:set --global chart.keda-add-ons-http.interceptor.tcpConnectTimeout ``` Once the values are set, users will need to then run `scheduler-k3s:ensure-charts` with either the `--force` flag or specify the `--chart` flag with a list of charts to force apply. ```shell dokku scheduler-k3s:ensure-charts --force dokku scheduler-k3s:ensure-charts --chart keda-add-ons-http ``` Note that the existing dokku-provided values cannot be removed, but can be overridden.

Requirements
A fresh VM running any of the following operating systems:
- Ubuntu 20.04 / 22.04 / 24.04 (amd64/arm64) - Any currently supported release
- Debian 11+ (amd64/arm64)
An SSH keypair that can be used for application deployment. If this exists before installation, it will be automatically imported into dokku.
Otherwise, you will need to import the keypair manually after installation using dokku ssh-keys:add.
Installation
To install the latest stable release, run the following commands as a user who has access to sudo:
wget -NP . https://dokku.com/install/v0.35.11/bootstrap.sh
sudo DOKKU_TAG=v0.35.11 bash bootstrap.sh
You can then proceed to configure your server domain (via dokku domains:set-global) and user access (via dokku ssh-keys:add) to complete the installation.
If you wish for a more unattended installation method, see these docs.
