带钥匙斗篷看门人侧车的可携式服务

Question

我正在尝试部署以下服务：

{{- if .Values.knativeDeploy }}
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
{{- if .Values.service.name }}
name: {{ .Values.service.name }}
{{- else }}
name: {{ template "fullname" . }}
{{- end }}
labels:
chart: "{{ .Chart.Name }}-{{ .Chart.Version | replace "+" "_" }}"
spec:
template:
spec:
containers:
- image: quay.io/keycloak/keycloak-gatekeeper:9.0.3
name: gatekeeper-sidecar
ports:
- containerPort: {{ .Values.keycloak.proxyPort }}
env:
- name: KEYCLOAK_CLIENT_SECRET
valueFrom:
secretKeyRef:
name: {{ template "keycloakclient" . }}
key: secret
args:
- --resources=uri=/*
- --discovery-url={{ .Values.keycloak.url }}/auth/realms/{{ .Values.keycloak.realm }}
- --client-id={{ template "keycloakclient" . }}
- --client-secret=$(KEYCLOAK_CLIENT_SECRET)
- --listen=0.0.0.0:{{ .Values.keycloak.proxyPort }} # listen on all interfaces
- --enable-logging=true
- --enable-json-logging=true
- --upstream-url=http://127.0.0.1:{{ .Values.service.internalPort }} # To connect with the main container's port
resources:
{{ toYaml .Values.gatekeeper.resources | indent 12 }}
- name: {{ .Chart.Name }}
image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
imagePullPolicy: {{ .Values.image.pullPolicy }}
env:
{{- range $pkey, $pval := .Values.env }}
- name: {{ $pkey }}
value: {{ quote $pval }}
{{- end }}
envFrom:
{{ toYaml .Values.envFrom | indent 10 }}
ports:
- containerPort: {{ .Values.service.internalPort }}
livenessProbe:
httpGet:
path: {{ .Values.probePath }}
port: {{ .Values.service.internalPort }}
initialDelaySeconds: {{ .Values.livenessProbe.initialDelaySeconds }}
periodSeconds: {{ .Values.livenessProbe.periodSeconds }}
successThreshold: {{ .Values.livenessProbe.successThreshold }}
timeoutSeconds: {{ .Values.livenessProbe.timeoutSeconds }}
readinessProbe:
httpGet:
path: {{ .Values.probePath }}
port: {{ .Values.service.internalPort }}
periodSeconds: {{ .Values.readinessProbe.periodSeconds }}
successThreshold: {{ .Values.readinessProbe.successThreshold }}
timeoutSeconds: {{ .Values.readinessProbe.timeoutSeconds }}
resources:
{{ toYaml .Values.resources | indent 12 }}
terminationGracePeriodSeconds: {{ .Values.terminationGracePeriodSeconds }}
{{- end }}

失败并出现以下错误：

Error from server (BadRequest): error when creating "/tmp/helm-template-workdir-290082188/jx/output/namespaces/jx-staging/env/charts/docs/templates/part0-ksvc.yaml": admission webhook "webhook.serving.knative.dev" denied the request: mutation failed: expected exactly one, got both: spec.template.spec.containers'

现在，如果我读了说明书(https://knative.dev/v0.15-docs/serving/getting-started-knative-app/)，我可以看到这个例子：

apiVersion: serving.knative.dev/v1 # Current version of Knative
kind: Service
metadata:
name: helloworld-go # The name of the app
namespace: default # The namespace the app will use
spec:
template:
spec:
containers:
- image: gcr.io/knative-samples/helloworld-go # The URL to the image of the app
env:
- name: TARGET # The environment variable printed out by the sample app
value: "Go Sample v1"

它有完全相同的结构。现在，我的问题是：

1. 如何在不等待部署的情况下验证我的yam？Intellij有一个k8n插件，但我找不到机器可消耗的serving.knative.dev/v1的CRD模式。(https://knative.dev/docs/serving/spec/knative-api-specification-1.0/)
2. knive允许有多个容器吗？(该配置与apiVersion:apps/v1 kind:Deployment完美配合(

Answer 1

多容器是版本0.16的alpha特性。需要通过在config-featuresConfigMap中将multi-container设置为enabled来启用此功能。因此，使用编辑配置图

CCD_ 4并启用该功能。

apiVersion: v1
kind: ConfigMap
metadata:
name: config-features
namespace: knative-serving
labels:
serving.knative.dev/release: devel
annotations:
knative.dev/example-checksum: "983ddf13"
data:
_example: |
...
# Indicates whether multi container support is enabled
multi-container: "enabled"
...

Answer 2

您使用的Knative是什么版本？

在0.16中添加了对多个容器的支持作为alpha特性。如果您没有使用0.16或更高版本，或者没有启用alpha标志，则请求可能会被阻止。

Knative中有许多边缘情况需要定义以支持多容器，因此默认情况是保守的，在探索约束之前只允许使用一个容器。
