Helm lifecycle commands in deployment - kubernetes

Question

I have deployment.yaml template.
I have AWS EKS 1.8 and same kubectl.
I'm using Helm 3.3.4.
When I tried to deploy same template directly thru kubectl apply -f deployment.yaml,is everything good, init containers and main container in pod works fine.
But if I tried to start deployment thru Helm I got this error:
OCI runtime exec failed: exec failed: container_linux.go:349: starting
container process caused "process_linux.go:101: executing setns
process caused \"exit status 1\"": unknown\r\n"
kubectl describe pods osad-apidoc-6b74c9bcf9-tjnrh
Looks like I have missed something in annotations or I'm using wrong syntaxes in command description.
Some not important parameters are omitted in this example:
apiVersion: apps/v1
kind: Deployment
metadata:
name: {{ include "apidoc.fullname" . }}
labels:
{{- include "apidoc.labels" . | nindent 4 }}
spec:
template:
metadata:
containers:
- name: {{ .Chart.Name }}
image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"
imagePullPolicy: {{ .Values.image.pullPolicy }}
ports:
- name: http
containerPort: 80
protocol: TCP
lifecycle:
postStart:
exec:
command:
- /bin/sh
- -c
- |
echo 'ServerName 127.0.0.1' >> /etc/apache2/apache2.conf
a2enmod rewrite
a2enmod headers
a2enmod ssl
a2dissite default
a2ensite 000-default
a2enmod rewrite
service apache2 start
I have tried invoke simple command like:
lifecycle:
postStart:
exec:
command: ['/bin/sh', '-c', 'printenv']
Unfortunately I got same error.
If I will delete this Lifecycle everything works fine thru Helm.
But I need invoke this commands, I can't omit this steps.
Also I checked helm template thru lint, looks good:
