Im using the helm SDK and it works great, for my testing using the fake option which works(for kubeconfig),
Now when I update the kubeconfig
to my cluster I notice that during installation the chart is stuck on status pending,
and it stuck forever in this state until I'm deleting & installing it again,(manually)
My question is how to solve this issue with the
Helm SDK (via code only) https://pkg.go.dev/helm.sh/helm/v3,
I mean wait for a while and if the status is pending after 3 min delete and reinstall it again... or try upgrade before
This is the code
kubeConfigPath, err := findKubeConfig()
if err != nil {
fmt.Println()
}
actionConfig := &action.Configuration{
}
cfg := cli.New()
clientGetter := genericclioptions.NewConfigFlags(false)
clientGetter.KubeConfig = &kubeConfigPath
actionConfig.Init(clientGetter, "def", "memory", log.Printf)
if err != nil {
fmt.Println(err)
}
chart, err := installation.InstallChart(cfg, "test", "chart1", "./charts/dns", nil, actionConfig)
if err != nil {
fmt.Println(err)
}
fmt.Println(chart)
}
func findKubeConfig() (string, error) {
env := os.Getenv("KUBECONFIG")
if env != "" {
return env, nil
}
path, err := homedir.Expand("~/.kube/config")
if err != nil {
return "", err
}
return path, nil
}
Looking at the example, I don't know what the installation
package is but I feel like you would need to use a Loader
(maybe you are using it in that pkg)
from a quick search over the github issues I found someone with a similar problem - and they got the same suggestion. here is a derived example:
package main
import (
"fmt"
"os"
"helm.sh/helm/v3/pkg/action"
"helm.sh/helm/v3/pkg/chart/loader"
"helm.sh/helm/v3/pkg/kube"
"helm.sh/helm/v3/pkg/release"
_ "k8s.io/client-go/plugin/pkg/client/auth"
)
func main() {
chartPath := "./charts/dns"
chart, err := loader.Load(chartPath)
if err != nil {
panic(err)
}
kubeconfigPath := findKubeConfig()
releaseName := "test"
releaseNamespace := "default"
actionConfig := new(action.Configuration)
if err := actionConfig.Init(kube.GetConfig(kubeconfigPath, "", releaseNamespace), releaseNamespace, os.Getenv("HELM_DRIVER"), func(format string, v ...interface{}) {
fmt.Sprintf(format, v)
}); err != nil {
panic(err)
}
iCli := action.NewInstall(actionConfig)
iCli.Namespace = releaseNamespace
iCli.ReleaseName = releaseName
rel, err := iCli.Run(chart, nil)
if err != nil {
panic(err)
}
fmt.Println("Successfully installed release: ", rel.Name)
rel.Info.Status
// check Release Status, feel free to run it in a go routine along the deletetion logic
upCli := action.NewUpgrade(actionConfig)
upgradedRel, err := pollAndUpdate(rel.Info.Status, upCli) // see if its better to just run that code here directly :shrug:
// if we still on pending, then delete it
if upgradedRel.Info.Status.IsPending() {
unCli := action.NewUninstall(actionConfig)
res, err := unCli.Run(rel.Name)
if err != nil {
panic(err)
}
}
}
func pollAndUpdate(originalRel *release.Release, upgradeCli *action.Upgrade) (*release.Release, error) {
if !originalRel.Info.Status.IsPending() {
return originalRel, nil
}
c := time.Tick(10 * time.Second) // we gonna time it out besides checking repeatedly
var rel *release.Release = originalRel
for _ = range c {
//check the status and try and upgrade
for rel.Info.Status.IsPending() { // https://pkg.go.dev/helm.sh/helm/[email protected]/pkg/release#Status.IsPending
// run the upgrade command you have
// its this function: https://github.com/helm/helm/blob/main/pkg/action/upgrade.go#L111
rel, err := upgradeCli.Run(/*you gotta get all the values this needs*/)
if err != nil {
panic(err)
}
}
}
return rel, nil
}
