I need to render between a the backend name and uid used by a logged in user.
Just as I do Hello {{ user.username }} !
I need to do Backend name: {{ dont know }}
I need to do Uid: {{ dont know }}
I am not sure which value I am able to query in the template.
Thnaks.
EDIT:
SOLVED:
{{user.social_auth.get.provider}}
{{ user.social_auth.get.uid }}
Thats the way.
Thanks!

Struggling with some helm templating...
I'm trying to pass a separate yaml file with springboot parameters to helm, and have them split by environment... then I want to pass the environment to helm using --set env=staging
Feels like I've tried everything but clearly I'm lacking a fundamental understanding...
My _helpers.tpl contains these:
{{- define "env" }}
{{- printf "%s" .Values.env }}
{{- end }}
{{ define "configmap.metadata" }}
name: {{ .Values.name }}-config
{{ end }}
{{ define "configmap.properties" }}
{{ index .Values.environment (include "env" .) "properties" | indent 4 }}
{{ end }}
The template for the config map:
apiVersion: v1
kind: ConfigMap
metadata:
{{ include "configmap.metadata" . }}
data:
app.properties: |-
{{ include "configmap.properties" .}}
And the yaml file containing the properties looks like this:
environment:
staging:
properties:
spring:
datasource:
url: something
username: something
password: something
app1:
key: something
secret: something
baseUri: something
app2:
bootstrap_server: something
bootstrap_port: something
registry_schema: something
production:
properties:
spring:
etc, etc
And then I want to select the environment using set. I'm testing with:
helm template test . -f values.yaml -f properties.yaml --set env=staging
I think I've just tried so many things that I just can't see the wood for the trees! The error I'm seeing is:
Error: template: microservice/templates/configmap.yaml:7:7: executing "microservice/templates/configmap.yaml" at <include "configmap.properties" .>: error calling include: template: microservice/templates/_helpers.tpl:56:76: executing "configmap.properties" at <4>: wrong type for value; expected string; got map[string]interface {}
EDIT:
After tweaking, I'm still getting an error, but I'm seeing something in the configmap.. but I wonder if the error is due to the 8 spaces on the first line..
data:
app.properties: |-
app2:
bootstrap_port: something
bootstrap_server: something
registry_schema: something
app1:
baseUri: something
key: something
secret: something
spring:
datasource:
password: something
url: something
username: something
I think your actual error message is around the way you're using the .Values.environment.production.properties value. It's a YAML map, but the indent function expects it to be a string. You should be able to see some odd indentation and maybe an odd [map spring [map datasource ...]] string if you use the helm template --debug option.
When you go to render the ConfigMap, you need to make sure to do two things. Since the data you have is structured properties, you need to use the lightly-documented toYaml function to convert it back to YAML. This will begin at the first column, so you need to apply the indent function to it, and then you need to make sure the markup that invokes it is also at the first column (indent should be the only thing that supplies indentation).
data:
app.properties: |-
{{ include "configmap.properties" . | indent 4}}
{{/*- starts at column 1, but includes the `indent` function */}}
{{ define "configmap.properties" }}
{{- index .Values.environment (.Values.env) "properties" | toYaml }}
{{/*- starts at first column, includes `toYaml`, does not include `indent` */}}
{{- end }}
I am trying to create a helm template for Istio's ServiceEntry which has a list of addresses for static ip addresses. In values.yaml, I have
- name: test-se
namespace: test-se-ns
egressUrls:
- mydbhost.com
port: 32306
protocol: TCP
ipAddress: 10.2.2.2
In the .tpl file I am trying to add the value of ipAddress to a list
{{- with .ipAddress }}
addresses:
- {{ .ipAddress | quote }}
{{- end }}
Always fails with exception
templates/_service_entry.tpl:18:13: executing "common.serviceentry.tpl" at <.ipAddress>: can't evaluate field ipAddress in type string
Any idea what I am doing wrong?
If you use with you make the thing that you have used as with the context inside that block.
So, use the dot to refer to it.
{{- with .ipAddress }}
addresses:
- {{ . | quote }}
{{- end }}
From the docs:
{{with pipeline}} T1 {{end}}
If the value of the pipeline is empty, no output is generated;
otherwise, dot is set to the value of the pipeline and T1 is
executed.
In this case, an if seems also fitting, since you do not much with the new context.
{{- if .ipAddress }}
addresses:
- {{ .ipAddress | quote }}
{{- end }}
when you use with in Helm, you change the scope of the ., so Helm looks for an object and not a string, you can read more about it in the docs.
but anyway, I think that in your case, you need to use range instead of with, you can see an example here
Using the helm function tpl or other similar functions, how do you pass in a file specific variable and the top level Values? Here is a concrete example:
# values
template: "{{ .Values.name }} drinks {{ $drink }}"
name: "Tom"
# template
{{- $drink := "coffee" -}}
# how do I pass $drink into tpl???
{{ tpl .Values.template . }}
# expected output
Tom drinks coffee
It seems like when I do this it just passes in the .Values, but not the file specific $drink variable that's defined within the template and I get the error: error calling tpl. I don't see anything in the docs for how to merge these values together or just pass them both into the function.
Helm is using a slightly modified version of sprig functions. Most things from sprig are available.
You can use one of the dict functions to set the value or create a new dict that you pass as context.
{{ $_ := set .Values "drink" $drink }}
{{ tpl .Values.template . }}
In this case I have set a new key on the Values dict.
template: "{{ .Values.name }} drinks {{ .Values.drink }}"
I could not find anything by just googling, does Helm support private values?
So I have my chart and my values.yaml
privateProp: hello
publicProp: world
I have some values that I want to exposed to the end user of my chart and others that I do not want, however those "private" values are being used in many places.
For example: publicProps is overridable by the user of the chart, but I would like to block access to privateProp, however it is reused in many places:
containers:
name: {{.Values.privateProp}}
nodeSelector:
name: {{.Values.privateProp}}
I saw there is {{$privateProp := "hello"}}, but it is not clear how I can access it elsewhere in my files
How can I achieve this?
Ok, I have found a solution to my problem.
You can create a file called _variables.tpl, the name does not matter
and then declare a variable:
{{- define "privateProp" -}}
{{- print "hello" -}}
{{- end -}}
and then you can use it wherever you want in your chart by doing this:
spec:
containers:
- name: {{ .Values.dashboard.containers.name }}
image: {{ .Values.dashboard.containers.image.repository }}:{{ .Values.dashboard.containers.image.tag }}
imagePullPolicy: Always
ports:
- containerPort: {{ include "privateProp" . }} # <== This
So I am deploying my spring boot app using helm. I am following a pre-existing formula used by our company to try and accomplish this task, but for some reason I am unable.
my postgresql-secrets.yml file contains the following
apiVersion: v1
kind: Secret
metadata:
name: {{ template "codes-chart.fullname" . }}-postgresql
labels:
app: {{ template "codes-chart.name" . }}
release: {{ .Release.Name }}
heritage: {{ .Release.Service }}
data:
SPRING_DATASOURCE_URL: {{ .Values.secrets.springDatasourceUrl | b64enc }}
SPRING_DATASOURCE_USERNAME: {{ .Values.secrets.springDatasourceUsername | b64enc}}
SPRING_DATASOURCE_PASSWORD: {{ .Values.secrets.springDatasourcePassword | b64enc}}
This picks up the values in the values.yaml file
secrets:
springDatasourceUrl: PLACEHOLDER
springDatasourceUsername: PLACEHOLDER
springDatasourcePassword: PLACEHOLDER
The place holders are being overwritten in helm using a variable override in the environment.
the secrets are referenced in the envFrom: of the codes-deployment.yaml
envFrom:
- configMapRef:
name: {{ template "codes-chart.fullname" . }}-application
- secretRef:
name: {{ template "codes-chart.fullname" . }}-postgresql
my helm file structure is as follows:
|helm
|-codes
|--configmaps
|---manifest
|----manifest-codes-configmap.yaml
|--templates
|---application-deploy-job.yaml
|---application-manifest-configmap.yaml
|---application-register-job.yaml
|---application-unregister-job.yaml
|---codes-application-configmap.yaml
|---codes-deployment.yaml
|---codes-hpa.yaml
|---codes-ingress.yaml
|---codes-service.yaml
|---postgresql-secret.yaml
|--values.yaml
|--Chart.yaml
The issues seems to be with the SPRING_DATASOURCE_URL:
if i use the private ip of the cloudsql db, then it says it is not accepting connections
if i use the jdbc url format:
ex: (jdbc:postgresql://google/<DATABASE_NAME>?cloudSqlInstance=<INSTANCE_CONNECTION_NAME>&socketFactory=com.google.cloud.sql.postgres.SocketFactory&user=<POSTGRESQL_USER_NAME>&password=<POSTGRESQL_USER_PASSWORD>)
then I get an 403 authentication error.
What am I doing wrong?
403 Forbidden:
The server understood the request, but is refusing to fulfill it.
The 403 for authenticated users with insufficient permissions.
403 indicates that the resource can not be provided. This may be because it is known that no level of authentication is sufficient, but it may be because the user is already authenticated and does not have authority.
Let me add some examples:
