      A bash script that does the same things you would do in a configuration step.

      You can use Go Template to generate a script.

      The list of parameters available for use in templates can be retrieved from the bashible-apiserver-context Secret as follows:

      kubectl -n d8-cloud-instance-manager get secrets bashible-apiserver-context -o jsonpath='{.data.input\.yaml}'| base64 -d

      For example:

      {{- range .nodeUsers }}
echo 'Tuning environment for user {{ .name }}'
# Some code for tuning user environment
{{- end }}

      You can also use the pre-defined bashbooster commands in the script. For example:

      bb-event-on 'bb-package-installed' 'post-install'
post-install() {
  bb-log-info "Setting reboot flag due to kernel was updated"
  bb-flag-set reboot
}

      Example of using the proxy parameters of ClusterConfiguration resource:

      bb-set-proxy
curl -I https://google.com
bb-unset-proxy

      test-function-with-proxy() {
  bb-set-proxy
