I have two environmental variables defined which are working fine. Apart from this, I have one JSON object serviceAccount which stored in manually created secret firebase-connector. As soon as I add this second part I got an error. I followed syntax but it's not working.

I need to pass a JWK as kubernetes environment variable to my app.
I created a file to store my key like so:
cat deploy/keys/access-signature-public-jwk
{
algorithm = "RS256"
jwk = {"kty":"RSA","e":"AQAB","n":"ghhDZxuUo6TaSvAlD23mLP6n_T9pQuJsFY4JWdBYTjtcp_8Q3QeR477jou4cScPGczWw2JMGnx-Ao_b7ewagSl7VHpECBFHgcnlAgs5j6jfnd3M9ADKD2Yc756iXlIMT9xKDblIcXQQYlXalqxGvnLRLv1KAgVVVpVWzQd6Iz8WdTnexVrh7L9N87QQbOWcAVWGHCWCLCBsVE7JbC-XDt9h9P1g1sMqMV-qp7HjSXUKWuF2NwOnL2VeFSED7gdefs2Za1UYqhfwxdGl7aaPDXhjib0cfg4NvbcXMzxDEVkeJqhdDfD82wHOs4qFvnFMVxq9n6VVExSxsJq8gBJ7Z2AmfoXpmZC1L1ZwULB2KKpFXDCzgBELPLrfyIf8mNnk2nuuLT-aaMsqy2uB-ea3du4lyWo9MLk6x-L5g-n1oADKFKBY9aP2QQwruCG92XSd7jA9yLtbgr9OGVCYezxIxFp4vW6KcmPwJQjozWtwkZjeo4hv-zhRac73WDox2hDkif7WPTuEvC21fRy3GvyPIUPKPJA8pJjb2TXT7DXknR97CTnOWicuh3HMoRlVIwUzM5SVLGSXex0VjHZKgLYwQYukg5O2rab_4NxpD6LqLHx1bbPssC7BedCIfWX1Vcae40tlfvJAM09MiwQPZjWRahW_fK_9X5F5_rtUhCznm32M"}
}
Which is then used to create a kubernetes secret like so:
kubectl create secret generic intimations-signature-public-secret --from-file=./deploy/keys/access-signature-public-jwk
Which is then retrived in the kubernetes environment variable as:
- name: ACCESS_SIGNATURE_PUBLIC_JWK
valueFrom:
secretKeyRef:
name: intimations-signature-public-secret
key: access-signature-public-jwk
And passed to the application.conf of the application likeso:
pac4j.lagom.jwt.authenticator {
signatures = [
${ACCESS_SIGNATURE_PUBLIC_JWK}
]
}
The pac4j library expects the config pac4j.lagom.jwt.authenticator as a json object. But get the following exception when I run this app:

I was wondering if there is any way to pass the environment variable as a json object instead of string. Please suggest. TIA.
First, the file access-signature-public-jwk is not a valid JSON file. You should update it as a valid one.
{
"algorithm" : "RS256",
"jwk" : {"kty":"RSA","e":"AQAB","n":"ghhDZxuUo6TaSvAlD23mLP6n_T9pQuJsFY4JWdBYTjtcp_8Q3QeR477jou4cScPGczWw2JMGnx-Ao_b7ewagSl7VHpECBFHgcnlAgs5j6jfnd3M9ADKD2Yc756iXlIMT9xKDblIcXQQYlXalqxGvnLRLv1KAgVVVpVWzQd6Iz8WdTnexVrh7L9N87QQbOWcAVWGHCWCLCBsVE7JbC-XDt9h9P1g1sMqMV-qp7HjSXUKWuF2NwOnL2VeFSED7gdefs2Za1UYqhfwxdGl7aaPDXhjib0cfg4NvbcXMzxDEVkeJqhdDfD82wHOs4qFvnFMVxq9n6VVExSxsJq8gBJ7Z2AmfoXpmZC1L1ZwULB2KKpFXDCzgBELPLrfyIf8mNnk2nuuLT-aaMsqy2uB-ea3du4lyWo9MLk6x-L5g-n1oADKFKBY9aP2QQwruCG92XSd7jA9yLtbgr9OGVCYezxIxFp4vW6KcmPwJQjozWtwkZjeo4hv-zhRac73WDox2hDkif7WPTuEvC21fRy3GvyPIUPKPJA8pJjb2TXT7DXknR97CTnOWicuh3HMoRlVIwUzM5SVLGSXex0VjHZKgLYwQYukg5O2rab_4NxpD6LqLHx1bbPssC7BedCIfWX1Vcae40tlfvJAM09MiwQPZjWRahW_fK_9X5F5_rtUhCznm32M"}
}
Steps I followed to validate.
kubectl create secret generic token1 --from-file=jwk.json
Mount the secret into the pod.
env:
- name: JWK
valueFrom:
secretKeyRef:
name: token
key: jwk.json
exec to the pod and check the env variable JWK
$ echo $JWK
{ "algorithm" : "RS256", "jwk" : {"kty":"RSA","e":"AQAB","n":"ghhDZxuUo6TaSvAlD23mLP6n_T9pQuJsFY4JWdBYTjtcp_8Q3QeR477jou4cScPGczWw2JMGnx-Ao_b7ewagSl7VHpECBFHgcnlAgs5j6jfnd3M9ADKD2Yc756iXlIMT9xKDblIcXQQYlXalqxGvnLRLv1KAgVVVpVWzQd6Iz8WdTnexVrh7L9N87QQbOWcAVWGHCWCLCBsVE7JbC-XDt9h9P1g1sMqMV-qp7HjSXUKWuF2NwOnL2VeFSED7gdefs2Za1UYqhfwxdGl7aaPDXhjib0cfg4NvbcXMzxDEVkeJqhdDfD82wHOs4qFvnFMVxq9n6VVExSxsJq8gBJ7Z2AmfoXpmZC1L1ZwULB2KKpFXDCzgBELPLrfyIf8mNnk2nuuLT-aaMsqy2uB-ea3du4lyWo9MLk6x-L5g-n1oADKFKBY9aP2QQwruCG92XSd7jA9yLtbgr9OGVCYezxIxFp4vW6KcmPwJQjozWtwkZjeo4hv-zhRac73WDox2hDkif7WPTuEvC21fRy3GvyPIUPKPJA8pJjb2TXT7DXknR97CTnOWicuh3HMoRlVIwUzM5SVLGSXex0VjHZKgLYwQYukg5O2rab_4NxpD6LqLHx1bbPssC7BedCIfWX1Vcae40tlfvJAM09MiwQPZjWRahW_fK_9X5F5_rtUhCznm32M"} }
Copy the content to a file
echo $JWK > jwk.json
Validate the file
$ jsonlint-php jwk.json
Valid JSON (jwk.json)
If I use the file you are given and followed the same steps. It gives an json validation error. Also, env variables are always strings. You have to convert them into the required types in your code.
$ echo $JWK
{ algorithm = "RS256" jwk = {"kty":"RSA","e":"AQAB","n":"ghhDZxuUo6TaSvAlD23mLP6n_T9pQuJsFY4JWdBYTjtcp_8Q3QeR477jou4cScPGczWw2JMGnx-Ao_b7ewagSl7VHpECBFHgcnlAgs5j6jfnd3M9ADKD2Yc756iXlIMT9xKDblIcXQQYlXalqxGvnLRLv1KAgVVVpVWzQd6Iz8WdTnexVrh7L9N87QQbOWcAVWGHCWCLCBsVE7JbC-XDt9h9P1g1sMqMV-qp7HjSXUKWuF2NwOnL2VeFSED7gdefs2Za1UYqhfwxdGl7aaPDXhjib0cfg4NvbcXMzxDEVkeJqhdDfD82wHOs4qFvnFMVxq9n6VVExSxsJq8gBJ7Z2AmfoXpmZC1L1ZwULB2KKpFXDCzgBELPLrfyIf8mNnk2nuuLT-aaMsqy2uB-ea3du4lyWo9MLk6x-L5g-n1oADKFKBY9aP2QQwruCG92XSd7jA9yLtbgr9OGVCYezxIxFp4vW6KcmPwJQjozWtwkZjeo4hv-zhRac73WDox2hDkif7WPTuEvC21fRy3GvyPIUPKPJA8pJjb2TXT7DXknR97CTnOWicuh3HMoRlVIwUzM5SVLGSXex0VjHZKgLYwQYukg5O2rab_4NxpD6LqLHx1bbPssC7BedCIfWX1Vcae40tlfvJAM09MiwQPZjWRahW_fK_9X5F5_rtUhCznm32M"} }
$ echo $JWK > jwk.json
$ jsonlint-php jwk.json
jwk.json: Parse error on line 1:
{ algorithm = "RS256"
-^
Expected one of: 'STRING', '}'
Although not a direct answer but an alternate solution to this problem.
As #hariK pointed out environment variables are always strings and in order to consume them as json we would need to convert the env var read as string into json.
However, in my case, this was not a viable solution because I was using a lib that was expecting a Config object and not a json object directly which would have meant a lot of work. Converting string -> json -> Config. Plus this approach is inconsistent with how Config object was being built in the developement scenarios i.e., json -> Config. See here.
The framework I am using to build this app is based on Play Framework which allows to modularize application configs in separate files and then club the required pieces together in a desired config file, as shown below. You can read it more in detail here.
application.conf
include "/opt/conf/app1.conf"
include "/opt/conf/app2.conf"
This allowed me to make use of Using Secrets as files from a Pod
feature from kubernetes.
Basically, I created a small config file that contains a part of my main application configuration file, as shown below:
cat deploy/keys/signature-public-jwk
pac4j.lagom.jwt.authenticator {
signatures = [
{
algorithm = "RS256"
jwk = {"kty":"RSA","e":"AQAB","n":"ghhDZxuUo6TaSvAlD23mLP6n_T9pQuJsFY4JWdBYTjtcp_8Q3QeR477jou4cScPGczWw2JMGnx-Ao_b7ewagSl7VHpECBFHgcnlAgs5j6jfnd3M9ADKD2Yc756iXlIMT9xKDblIcXQQYlXalqxGvnLRLv1KAgVVVpVWzQd6Iz8WdTnexVrh7L9N87QQbOWcAVWGHCWCLCBsVE7JbC-XDt9h9P1g1sMqMV-qp7HjSXUKWuF2NwOnL2VeFSED7gdefs2Za1UYqhfwxdGl7aaPDXhjib0cfg4NvbcXMzxDEVkeJqhdDfD82wHOs4qFvnFMVxq9n6VVExSxsJq8gBJ7Z2AmfoXpmZC1L1ZwULB2KKpFXDCzgBELPLrfyIf8mNnk2nuuLT-aaMsqy2uB-ea3du4lyWo9MLk6x-L5g-n1oADKFKBY9aP2QQwruCG92XSd7jA9yLtbgr9OGVCYezxIxFp4vW6KcmPwJQjozWtwkZjeo4hv-zhRac73WDox2hDkif7WPTuEvC21fRy3GvyPIUPKPJA8pJjb2TXT7DXknR97CTnOWicuh3HMoRlVIwUzM5SVLGSXex0VjHZKgLYwQYukg5O2rab_4NxpD6LqLHx1bbPssC7BedCIfWX1Vcae40tlfvJAM09MiwQPZjWRahW_fK_9X5F5_rtUhCznm32M"}
}
]
}
Then created a kubernetes secret and mounted volumes in deployment to appear in the pod as file
kubectl create secret generic signature-public-secret --from-file=./deploy/secrets/signature-public-jwks.conf
// deployment yaml
spec:
containers:
- name: employee
image: "codingkapoor/employee-impl:latest"
volumeMounts:
- name: signature-public-secret-conf
mountPath: /opt/conf/signature-public-jwks.conf
subPath: signature-public-jwks.conf
readOnly: true
volumes:
- name: signature-public-secret-conf
secret:
secretName: signature-public-secret
Use this mounted file location in the application.conf to include the same
include file("/opt/conf/signature-public-jwks.conf")
Notice that the mountPath and the file location in the application.conf are same.
Advantages of this approach:
The solution is consistent with both the development and test, production environments as we could return json instead of string to the lib, as explained above
Secrets shouldn't be passed as environment variables anyway! You can read more about it here.
I am trying to figure out how to reference a global scoped environmental variable for input in to an action like so:
name: validate
on: pull_request
env:
CONFIG_PATH: configuration/conf.json
jobs:
upload_config:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v1
- name: create config
shell: bash -l {0}
run: |
mkdir `dirname ${CONFIG_PATH}`
echo "some config" > ${CONFIG_PATH}
- name: upload config
uses: actions/upload-artifact#v1
with:
name: config
path: ${{ CONFIG_PATH }}
However I am getting an invalid yaml error stating there is an "Unrecognized named-value: 'CONFIG_PATH'". If I try referencing the environmental variable like so:
path: ${CONFIG_PATH}
I get a "Path does not exist ${CONFIG_PATH}" error.
Any ideas?
I couldn't find a clear example of it in the docs but you need to use the env context for this like so:
path: ${{ env.CONFIG_PATH }}
I've a kubernetes cronjob manifest file.In that file I've defined enviornment variables.I'm generating yaml using a shell script but while using the yaml using kubectl create -f. I'm getting the following validation error
error validating "cron.yaml": error validating data: [ValidationError(CronJob.spec.jobTemplate.spec.template.spec.containers[0].envFrom[0].configMapRef): invalid type for io.k8s.api.core.v1.ConfigMapEnvSource: got "array", expected "map".
Can anyone suggest me how to resolve this?
You have a mistake in the syntax.
There are two approaches, using valueFrom for individual values or envFrom for multiple values.
valueFrom is used inside the env attribute.valueFrom will inject the value of a a key from the referenced configMap.
spec:
template:
spec:
containers:
- name: ad-sync
image: foo.azurecr.io/foobar/ad-sync
command: ["dotnet", "AdSyncService.dll"]
args: []
env:
- name: AdSyncService
valueFrom:
configMapKeyRef:
name: ad-sync-service-configmap
key: log_level
envFrom is used direct inside the container attribute.envFrom will inject All configMap keys as environment variables
spec:
template:
spec:
containers:
- name: ad-sync
image: foo.azurecr.io/foobar/ad-sync
command: ["dotnet", "AdSyncService.dll"]
envFrom:
- configMapRef:
name: ad-sync-service-configmap
I would like to provide an environment variable to an OpenShift pod and within that variable reference other environment variables defined in the container.
For example, I define an environment variable called JAVA_CMD_LINE in OpenShift and set it to:
$HEAP_SETTING -Djavax.net.ssl.trustStore=/var/.keystore/cacerts -jar abc.jar
Where $HEAP_SETTING is set to -XMX=1G when the container starts.
In my container, there is a startup script that looks like:
java $JAVA_CMD_LINE
What I would expect is that then the container runs, the following is executed:
java -XMX=1G -Djavax.net.ssl.trustStore=/var/.keystore/cacerts -jar abc.jar
But instead what I see is:
java '$HEAP_SETTING' -Djavax.net.ssl.trustStore=/var/.keystore/cacerts -jar abc.jar
How do I provide the variable?
Update: Adding details from the YML file.
spec:
containers:
- env:
- name: OPENSHIFT_ENABLE_OAUTH
value: 'true'
- name: OPENSHIFT_ENABLE_REDIRECT_PROMPT
value: 'true'

value: 'true'
- name: JAVA_CMD_LINE
value: >-
-Djavax.net.ssl.trustStore=/var/cert/.keystore/cacerts
-Dfile.encoding=UTF8
$HEAP_SETTING
Update 2 - The error that I see:
+ exec java -Djavax.net.ssl.trustStore=/var/jenk-cert/.keystore/cacerts -Djavax.net.ssl.trustStorePassword=changeit -Dfile.encoding=UTF8 '$(HEAP_SETTING)' -Duser.home=/var/lib/jenkins -Djavamelody.application-name=JENKINS -jar /usr/lib/jenkins/jenkins.war
Picked up JAVA_TOOL_OPTIONS: -XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap -Dsun.zip.disableMemoryMapping=true
Error: Could not find or load main class $(HEAP_SETTING)
Try using:
spec:
containers:
- env:
- name: OPENSHIFT_ENABLE_OAUTH
value: 'true'
- name: OPENSHIFT_ENABLE_REDIRECT_PROMPT
value: 'true'
- name: KUBERNETES_MASTER
value: 'https://kubernetes.default:443'
- name: KUBERNETES_TRUST_CERTIFICATES
value: 'true'
- name: JAVA_CMD_LINE
value: >-
-Djavax.net.ssl.trustStore=/var/cert/.keystore/cacerts
-Dfile.encoding=UTF8
$(HEAP_SETTING)
Any time you are setting the value of an environment variable, if you need to compose the value from other environment variables that are already being set, you can use $(<VARNAME>) in the value.
IOW, use $(HEAP_SETTING) and not just $HEAP_SETTING.
UPDATE 1
Actually this will not work. This is because HEAP_SETTING is not in the set of environment variables you are setting via the deployment config, so it will pass the literal value $(HEAP_SETTING). This can't be used where the environment variable you are trying to use is populated by startup code in the image.
I am trying to create an Openshift template for a Job that passes the job's command line arguments in a template parameter using the following template:
apiVersion: v1
kind: Template
metadata:
name: test-template
objects:
- apiVersion: batch/v2alpha1
kind: Job
metadata:
name: "${JOB_NAME}"
spec:
parallelism: 1
completions: 1
autoSelector: true
template:
metadata:
name: "${JOB_NAME}"
spec:
containers:
- name: "app"
image: "batch-poc/sample-job:latest"
args: "${{JOB_ARGS}}"
parameters:
- name: JOB_NAME
description: "Job Name"
required: true
- name: JOB_ARGS
description: "Job command line parameters"
Because the 'args' need to be an array, I am trying to set the template parameter using JSON syntax, e.g. from the command line:
oc process -o=yaml test-template -v=JOB_NAME=myjob,JOB_ARGS='["A","B"]'
or programmatically through the Spring Cloud Launcher OpenShift Client:
OpenShiftClient client;
Map<String,String> templateParameters = new HashMap<String,String>();
templateParameters.put("JOB_NAME", jobId);
templateParameters.put("JOB_ARGS", "[ \"A\", \"B\", \"C\" ]");
KubernetesList processed = client.templates()
.inNamespace(client.getNamespace())
.withName("test-template")
.process(templateParameters);
In both cases, it seems to fail because Openshift is interpreting the comma after the first array element as a delimiter and not parsing the remainder of the string.
The oc process command sets the parameter value to '["A"' and reports an error: "invalid parameter assignment in "test-template": "\"B\"]"".
The Java version throws an exception:
Error executing: GET at: https://kubernetes.default.svc/oapi/v1/namespaces/batch-poc/templates/test-template. Cause: Can not deserialize instance of java.util.ArrayList out of VALUE_STRING token\n at [Source: N/A; line: -1, column: -1] (through reference chain: io.fabric8.openshift.api.model.Template[\"objects\"]->java.util.ArrayList[0]->io.fabric8.kubernetes.api.model.Job[\"spec\"]->io.fabric8.kubernetes.api.model.JobSpec[\"template\"]->io.fabric8.kubernetes.api.model.PodTemplateSpec[\"spec\"]->io.fabric8.kubernetes.api.model.PodSpec[\"containers\"]->java.util.ArrayList[0]->io.fabric8.kubernetes.api.model.Container[\"args\"])
I believe this is due to a known Openshift issue.
I was wondering if anyone has a workaround or an alternative way of setting the job's parameters?
Interestingly, if I go to the OpenShift web console, click 'Add to Project' and choose test-template, it prompts me to enter a value for the JOB_ARGS parameter. If I enter a literal JSON array there, it works, so I figure there must be a way to do this programmatically.
We worked out how to do it; template snippet:
spec:
securityContext:
supplementalGroups: "${{SUPPLEMENTAL_GROUPS}}"
parameters:
- description: Supplemental linux groups
name: SUPPLEMENTAL_GROUPS
value: "[14051, 14052, 48, 65533, 9050]"
In our case we have 3 files :
- environment configuration,
- template yaml
- sh file which run oc process.
And working case looks like this :
environment file :
#-- CORS ---------------------------------------------------------
cors_origins='["*"]'
cors_acceptable_headers='["*","Authorization"]'
template yaml :
- apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
name: plugin-common-cors
annotations:
kubernetes.io/ingress.class: ${ingress_class}
config:
origins: "${{origins}}"
headers: "${{acceptable_headers}}"
credentials: true
max_age: 3600
plugin: cors
sh file running oc :
if [ -f templates/kong-plugins-template.yaml ]; then
echo "++ Applying Global Plugin Template ..."
oc process -f templates/kong-plugins-template.yaml \
-p ingress_class="${kong_ingress_class}" \
-p origins=${cors_origins} \
-p acceptable_headers=${cors_acceptable_headers} \
-p request_per_second=${kong_throttling_request_per_second:-100} \
-p request_per_minute=${kong_throttling_request_per_minute:-2000} \
-p rate_limit_by="${kong_throttling_limit_by:-ip}" \
-o yaml \
> yaml.tmp && \
cat yaml.tmp | oc $param_mode -f -
[ $? -ne 0 ] && [ "$param_mode" != "delete" ] && exit 1
rm -f *.tmp
fi
The sh file should read environment file.
