Is it possible to print to helm install (or helm upgrade) output the logs of the deploying containers (logs that are available by kubectl logs command)?

  • I am currently working on a solution within our CI/CD system to do just that. it is what everyone really needs: To get the log output of a helmChart deployment when it fails. The challenge is to connect the dots. * extract the names from the helmchart to create the parameters for a kubectl -wait process to connnect to the pod created by the helmchart deployment. I keep you posted....

Helm does not launch pods to deploy your workloads. Helm locally renders the charts into standard Kubernetes manifests, and applies them. There is no server side component to Helm (since Helm 3).

If you want to get logs from deployed pods, do so with standard kubectl logs commands against the deployed pods. If you want to view what Helm is doing, use the --debug parameter to Helm, which will output the manifests that Helm applied.


Short answer: no. You would most likely run helm commands from your own workstation.

For those logs to be available through "kubectl logs", you would have to start a Pod, executing your "helm install" command. Maybe using a Job. Although this also means having some ServiceAccount with enough privileges to install objects on behalf of Helm.

    I need these logs to be available in CI/CD system. Developers should watch these logs without monitoring kubernetes pods manually.

  • If going through logs in Kibana (assuming you have EFK) or pod logs is not enough: in my CI, logs of the commands executed during a job are collected in a file, which is then pushed, alongside other reports into some s3 bucket.

  • As I understand, it is too hard to find necessary logs in Kibana if use EFK (we use ELK, and these logs aren't so convenient). I thought that the task is so simple. If the helm chart installation/upgrade is failed, I want to get logs of failed pods to stdout (or names of the failed pods).

  • EFK is quite simple, you would need one filter: the name of your pipelinerun. to find back its logs. Now, as I already suggested: if your end-users are not up to the task of filtering based on a single field in Kibana: then, you need to keep those logs somewhere else. Eg: s3. And you can probably shut down your EFK, being too complicated and all, .. it still consumes a lot usually.

  • the log search tools are just a super inefficient workarounds for this issue, sure its a solution but a very ugly one

You can try a workaround by using the --wait flag with helm install or helm upgrade. This will cause the command to wait until the deployment is complete and all of the pods are ready, and then it will print the logs for the pods.

example: helm install my-release my-chart --wait

This will install the chart and then wait until the deployment is complete before printing the logs for the pods.

You can also specify a timeout for the --wait flag, like so:

helm install my-release my-chart --wait --timeout 600

This will wait up to 10 minutes for the deployment to complete before timing out and returning.

The catch is that the --wait flag only works if the chart being installed or upgraded has a Deployment or StatefulSet as the primary resource type. It will not work with other resource types such as DaemonSet or Job.
