我正在尝试使用istio在kubernetes上设置mongodb。我的状态集如下:
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: treeservice
namespace: staging
spec:
serviceName: tree-service-service
replicas: 1
selector:
matchLabels:
app: treeservice
template:

app: treeservice
spec:

initialDelaySeconds: 60 #wait this period after staring fist time
periodSeconds: 30 # polling interval every 5 minutes
timeoutSeconds: 60
livenessProbe:
exec:

initialDelaySeconds: 60 #wait this period after staring fist time
periodSeconds: 30 # polling interval every 5 minutes
timeoutSeconds: 60
command: ["/bin/bash"]
args: ["-c","mongod --port 30010 --replSet test"] #bind to localhost
volumeClaimTemplates:
- metadata:
name: mongodb-cache-data
spec:
accessModes: [ "ReadWriteOnce" ]
storageClassName: fast
resources:
requests:
storage: 300Gi
但是，未创建容器，并且我看到以下错误:
kubectl describe statefulset treeservice -n staging
Warning FailedCreate 1m (x159 over 1h) statefulset-controller create Pod treeservice-0 in StatefulSet treeservice failed error: Pod "treeservice-0" is invalid: spec.containers[1].env[7].name: Invalid value: "ISTIO_META_statefulset.kubernetes.io/pod-name": a valid environment variable name must consist of alphabetic characters, digits, '_', '-', or '.', and must not start with a digit (e.g. 'my.env-name', or 'MY_ENV.NAME', or 'MyEnvName1', regex used for validation is '[-._a-zA-Z][-._a-zA-Z0-9]*')
我假设
treeservice是有效的 pods 名称。我想念什么吗？
请您参考如下方法:
我猜这是由于此问题https://github.com/istio/istio/issues/9571仍处于打开状态
我使用以下方法使其暂时可用:
annotations:
sidecar.istio.io/inject: "false"
