I have existing Configmap:
apiVersion: v1
kind: ConfigMap
metadata:
name: student
namespace: {{ .Release.Namespace }}
data:
student-1: |-
id: 4
name: "s1"
group_list:
- maths
- science
student-2: |-
id: 5
name: "s2"
group_list:
- finance
- history
I need to create mutliple configmaps student-1 , student-2 from the above configmap with following data.
For student-1:
apiVersion: v1
kind: ConfigMap
metadata:
name: student-1
annotation: "maths,science"
data:
enrolled: "maths,science"
For student-2:
enrolled: "finance,history"
Please help me to get the desired output format. Thank you !
Helm Template:
{{- range $k, $v := (lookup "v1" "ConfigMap" "default" "student").data }}
apiVersion: v1
kind: ConfigMap
metadata:
name: {{ $k }}
annotation: {{ $v1 | quote }}
data:
{{- range $k1, $v1 := fromYaml $v }}
enrolled: {{ $v1 | quote }}
{{- end }}

I am running my pipeline in gitlab .. and this pipeline pull a helmfile from a github repo.. and when i am trying to deploy this error appears when start to put parsing because my values file like that
kubeContext: cech027
this is the helmfile
`

but i have this error since a week ( and we did not do any changes) ..
the gitlab uses a runner to run this pipeline..
this is the error : rror during helmfile.yaml.part.0 parsing: template: stringTemplate:11:69: executing "stringTemplate" at <.Values.kubeContext>: map has no entry for key "kubeContext"
and when i run from my local machine it deployed successfully
I couldn't find any documentation, but I keep seeing examples.
Like:
{{- if .Values.serviceAccount.create -}}
apiVersion: v1
kind: ServiceAccount
metadata:
name: {{- include "example.serviceAccountName" . -}} ##<=== {{- -}}
example: {{ .Values.example.example }} ##<=== {{ }}
labels:
{{- include "alma.labels" . | nindent 4 }} ##<=== {{- }}
{{- with .Values.serviceAccount.annotations }}
annotations:
{{- toYaml . | nindent 4 }}
{{- end }}
{{- end }}
Helm uses standard Go templating. Have a look at https://pkg.go.dev/text/template#hdr-Text_and_spaces In short {{- something }} means "trim left whitespace" and {{ something -}} means "trim right whitespace". | nindent 4 means "add 4 spaces before". You need this operators for correct indenting your yaml.
We use Prometheus alert manager for alerts, we have configured two receivers as attached below, Slack and Opsgenie.
The issue is that we are getting alerts in slack only but we are not receiving alerts in Opsgenie, we use the API keys and it's a working key, we tested it.
Not able to figure why we are not receiving alerts in Opsgenie too.

I'm trying to set Artillery config to be able to send nested JSON body. This is how my configuration looks like:
config:
target: <URL>
phases:
- duration: 10
arrivalRate: 20
processor: "./input-parser.js"
scenarios:
- flow:
- function: "parseJsonFile"
- post:
url: /workflow-instance
headers:
Content-Type: "application/json"
json:
name: "{{ name }}"
namespace: "{{ namespace }}"
template_name: "{{ template_name }}"
attributes: "{{ attributes }}"
- get:
url: "/workflow-instance/status?name={{ template_name }}&namespace={{ namespace }}"
I have a problem with "attributes" because the content of attributes is:
{ pod_name: 'POD_NAME', port: 'PORT_NUMBER' }
So basically, this will not work:
attributes: "{ pod_name: 'POD_NAME', port: 'PORT_NUMBER' }"
as well as this:
attributes:
pod_name: 'POD_NAME'
port: 'PORT_NUMBER'
I didn't found good examples for this particular case in Artillery docs.
The following workaround worked for me Embedding JSON Data into YAML file
Then you'd have to change your attributes for:
attributes: '{ pod_name: "POD_NAME", port: "PORT_NUMBER" }'
I'm using:
Artillery: 1.7.9
Artillery Pro: not installed (https://artillery.io/pro)
Node.js: v14.6.0
OS: darwin/x64
For future readers looking for hardcoding nested JSON, this worked for me:
...
scenarios:
-
flow:

post:
url: "/"
json:
text: {"filter": {"enabled": true}}
I have exported a variable:
export myparam=one
I have template: file.tmpl :
myproptmpl =
{{ if eq .myparam "one" }}
{{ "one" }}
{{ else }}
{{ "something else" }}
{{ end }}
And when I run confd I get:
# /usr/bin/confd -onetime -backend env
2016-04-20T15:21:58Z 8faae31d53a1 /usr/bin/confd[91]: ERROR template: file.tmpl:70:6: executing "file.tmpl" at <eq .myparam "one">: error calling eq: invalid type for comparison
I'm a newbie on confd. How can I compare an OS environment variable to values and based on them generate different resulting output file out of template?
You need get the variable first and after that then you can compare.
Ex.:
myproptmpl =
{{ if eq (getv .myparam) "one" }}
{{ "one" }}
{{ else }}
{{ "something else" }}
{{ end }}
