jenkins: Version 2.421
k8s: 1.25.0
plugin version: 4029.v5712230ccb_f8
When the fix for JENKINS-71956 was pushed, it changed the serializer to jackson, which has this long-standing bug:
This means that pod yamls can no longer utilize anchors.
Example Script:
pipeline {
agent {
kubernetes {
cloud "test"
defaultContainer 'aws'
yaml '''
apiVersion: v1
kind: Pod
spec:
containers:
- name: aws
image: "amazon/aws-cli:latest"
command:
- cat
tty: true
securityContext: &securityContext
runAsUser: 1000
runAsGroup: 1000
allowPrivilegeEscalation: false
- name: jnlp
securityContext: *securityContext
'''
}
}
stages {
stage('Test') {
steps{
script {
echo "Hello World"
}
}
}
}
}
And the resulting error:
hudson.remoting.ProxyException: com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `io.fabric8.kubernetes.api.model.SecurityContext` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('securityContext') at [Source: (ByteArrayInputStream); line: 16, column: 30] (through reference chain: io.fabric8.kubernetes.api.model.Pod["spec"]->io.fabric8.kubernetes.api.model.PodSpec["containers"]->java.util.ArrayList[1]->io.fabric8.kubernetes.api.model.Container["securityContext"]) at com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:63) at com.fasterxml.jackson.databind.DeserializationContext.reportInputMismatch(DeserializationContext.java:1754) at com.fasterxml.jackson.databind.DeserializationContext.handleMissingInstantiator(DeserializationContext.java:1379) at com.fasterxml.jackson.databind.deser.std.StdDeserializer._deserializeFromString(StdDeserializer.java:311) at com.fasterxml.jackson.databind.deser.BeanDeserializerBase.deserializeFromString(BeanDeserializerBase.java:1588) at com.fasterxml.jackson.databind.deser.BeanDeserializer._deserializeOther(BeanDeserializer.java:197) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:187) at com.fasterxml.jackson.databind.deser.impl.MethodProperty.deserializeAndSet(MethodProperty.java:129) at io.fabric8.kubernetes.model.jackson.SettableBeanPropertyDelegate.deserializeAndSet(SettableBeanPropertyDelegate.java:134) at com.fasterxml.jackson.databind.deser.BeanDeserializer.vanillaDeserialize(BeanDeserializer.java:310) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:177) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer._deserializeFromArray(CollectionDeserializer.java:361) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:246) at com.fasterxml.jackson.databind.deser.std.CollectionDeserializer.deserialize(CollectionDeserializer.java:30) at com.fasterxml.jackson.databind.deser.impl.MethodProperty.deserializeAndSet(MethodProperty.java:129) at io.fabric8.kubernetes.model.jackson.SettableBeanPropertyDelegate.deserializeAndSet(SettableBeanPropertyDelegate.java:134) at com.fasterxml.jackson.databind.deser.BeanDeserializer.vanillaDeserialize(BeanDeserializer.java:310) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:177) at com.fasterxml.jackson.databind.deser.impl.MethodProperty.deserializeAndSet(MethodProperty.java:129) at io.fabric8.kubernetes.model.jackson.SettableBeanPropertyDelegate.deserializeAndSet(SettableBeanPropertyDelegate.java:134) at com.fasterxml.jackson.databind.deser.BeanDeserializer.vanillaDeserialize(BeanDeserializer.java:310) at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:177) at com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.readRootValue(DefaultDeserializationContext.java:342) at com.fasterxml.jackson.databind.ObjectReader._bindAndClose(ObjectReader.java:2125) at com.fasterxml.jackson.databind.ObjectReader.readValue(ObjectReader.java:1501) at org.csanchez.jenkins.plugins.kubernetes.Serialization2.unmarshal(Serialization2.java:39) Caused: hudson.remoting.ProxyException: java.io.IOException: Unable to parse InputStream. at org.csanchez.jenkins.plugins.kubernetes.Serialization2.unmarshal(Serialization2.java:41) at org.csanchez.jenkins.plugins.kubernetes.PodTemplateUtils.parseFromYaml(PodTemplateUtils.java:696) at org.csanchez.jenkins.plugins.kubernetes.PodTemplateUtils.validateYamlContainerNames(PodTemplateUtils.java:725) at org.csanchez.jenkins.plugins.kubernetes.PodTemplateUtils.validateYamlContainerNames(PodTemplateUtils.java:715) at org.csanchez.jenkins.plugins.kubernetes.pipeline.PodTemplateStepExecution.start(PodTemplateStepExecution.java:155) at org.jenkinsci.plugins.workflow.cps.DSL.invokeStep(DSL.java:323) at org.jenkinsci.plugins.workflow.cps.DSL.invokeMethod(DSL.java:196) at org.jenkinsci.plugins.workflow.cps.CpsScript.invokeMethod(CpsScript.java:124) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:47) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:47) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:116) at com.cloudbees.groovy.cps.sandbox.DefaultInvoker.methodCall(DefaultInvoker.java:20) at org.jenkinsci.plugins.workflow.cps.LoggingInvoker.methodCall(LoggingInvoker.java:105) Also: hudson.remoting.ProxyException: org.jenkinsci.plugins.workflow.actions.ErrorAction$ErrorId: c6c6a41a-3eeb-4468-bd44-6a70d53f0488 Caused: hudson.remoting.ProxyException: java.lang.RuntimeException: Failed to parse yaml: " apiVersion: v1 kind: Pod spec: containers: -
