我正在使用头盔创建具有自定义istio-ingressgateway配置的YML。参见下面的脚本:
#!/usr/bin/env bash
helm template $ISTIO_DIR/install/kubernetes/helm/istio \
--name istio \
--namespace istio-system \
--set gateways.istio-ingressgateway.type=NodePort \
--set gateways.istio-ingressgateway.enabled=true \
--set gateways.istio-ingressgateway.replicaCount=1 \
--set gateways.istio-ingressgateway.ports.targetPort=80 \
--set gateways.istio-ingressgateway.ports.name=http2 \
--set gateways.istio-ingressgateway.ports.nodePort=30000 \
\
--set gateways.istio-ingressgateway.ports.targetPort=443 \
--set gateways.istio-ingressgateway.ports.name=https \
--set gateways.istio-ingressgateway.ports.nodePort=30443 \
\
--set gateways.istio-ingressgateway.ports.targetPort=31400 \
--set gateways.istio-ingressgateway.ports.name=tcp \
--set gateways.istio-ingressgateway.ports.nodePort=31400 \
\
--set gateways.istio-ingressgateway.ports.targetPort=15011 \
--set gateways.istio-ingressgateway.ports.name=tcp-pilot-grpc-tls \
--set gateways.istio-ingressgateway.ports.nodePort=32460 \
\
--set gateways.istio-ingressgateway.ports.targetPort=8060 \
--set gateways.istio-ingressgateway.ports.name=tcp-citadel-grpc-tls \
--set gateways.istio-ingressgateway.ports.nodePort=32027 \
\
--set gateways.istio-ingressgateway.ports.targetPort=15030 \
--set gateways.istio-ingressgateway.ports.name=http2-prometheus \
--set gateways.istio-ingressgateway.ports.nodePort=31926 \
\
--set gateways.istio-ingressgateway.ports.targetPort=15031 \
--set gateways.istio-ingressgateway.ports.name=http2-grafana \
--set gateways.istio-ingressgateway.ports.nodePort=31336 \
> eraseme.yaml
但是我得到这个错误:
2018/10/22 12:04:54警告:端口目标是一个表。忽略非表值[map [nodePort:31380端口:80 targetPort:80名称:http2] map [名称:https nodePort:31390端口:443] map [名称:tcp nodePort:31400端口:31400] map [端口:15011 targetPort:15011名称:tcp-pilot-grpc-tls] map [名称:tcp-城堡-grpc-tls端口:8060 targetPort:8060] map [名称:tcp-dns-tls port:853 targetPort:853] map [名称:http2-prometheus端口:15030 targetPort:15030] map [名称:http2-grafana端口:15031 targetPort:15031]] 2018/10/22 12:04:54警告:端口的目的地是一个表。忽略非表值[map [name:http2 nodePort:31380 port:80 targetPort:80] map [name:https nodePort:31390 port:443] map [name:tcp nodePort:31400 port:31400] map [name:tcp -pilot-grpc-tls端口:15011 targetPort:15011] map [名称:tcp-城堡-grpc-tls端口:8060 targetPort:8060] map [targetPort:853名称:tcp-dns-tls端口:853] map [名称:http2-prometheus端口:15030 targetPort:15030] map [名称:http2-grafana端口:15031 targetPort:15031]] 错误:“ istio / charts / gateways / templates / service.yaml”中的渲染错误:模板:istio / charts / gateways / templates / service.yaml:32:32:执行“ istio / charts / gateways / templates / service.yaml” “:位于:范围无法遍历http2-grafana
我应该如何正确执行此操作?

问题是关于用于指定数组变量的Helm语法。您可以这样做:
--set gateways.istio-ingressgateway.ports[0].targetPort=80 \
--set gateways.istio-ingressgateway.ports[0].name=http2 \
--set gateways.istio-ingressgateway.ports[0].nodePort=30000 \
\
--set gateways.istio-ingressgateway.ports[1].targetPort=443 \
--set gateways.istio-ingressgateway.ports[1].name=https \
--set gateways.istio-ingressgateway.ports[1].nodePort=30443 \
等,指定数组成员的索引。

我遇到了类似的问题,与其在命令行中添加长参数,不如将其添加到yaml文件中。
helm template $ISTIO_DIR/install/kubernetes/helm/istio \
--name istio \
--namespace istio-system > istio-default.yaml
然后您可以编辑istio-default.yaml
来添加您想要的额外端口
# istio-default.yaml (tips: search 31380 to locate this segment)
-
name: http2
nodePort: 31380
port: 80
targetPort: 80
# below is customized port for flask app for example
-
name: http-flask
nodePort: 31500
port: 5000
targetPort: 5000
现在您可以将配置创建/应用到系统
$ kubectl create -f istio-default.yaml
$ kubectl get svc istio-ingressgateway -n istio-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
istio-ingressgateway LoadBalancer 10.111.192.149 <pending> 80:31380/TCP,5000:31500/TCP,443:31390/TCP,31400:31400/TCP,15029:32630/TCP,15030:31878/TCP,15031:30152/TCP,15032:32060/TCP,15443:31852/TCP,15020:32235/TCP 8m26s
这也是在安装istio之后添加/删除端口的好方法
