go微应用程序总是得到"/greeter-srv“，没有这样的文件或目录kubernetes

Question

我尝试安装go微型应用程序，但总是出现以下错误，

`   Type     Reason     Age                 From               Message

`

我已经使用这个doc进行了安装，根据这个文档安装了deppentency etcd和NAT，并且它运行良好。任何人是在kubernetes中创建这个微应用程序的，我怀疑我的Dockerfile本身是否有任何问题或yaml，如果我运行任何错误，您能清除我，我没有从站点获得任何正确的kubernetes安装文档。

我使用下面的yaml文件进行kubernetes部署

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: default
  name: greeter
spec:
  replicas: 1
  selector:
    matchLabels:
      app: greeter-srv
  template:
    metadata:
      labels:
        app: greeter-srv
    spec:
      containers:
        - name: greeter
          command: [
        "/greeter-srv",
      ]
          image: 12345.dkr.ecr.ap-south-1.amazonaws.com/micro:latest
          imagePullPolicy: Always
          ports:
          - containerPort: 8080
            name: greeter-port
          env:
          - name: MICRO_SERVER_ADDRESS
            value: "0.0.0.0:8080"
          - name: MICRO_BROKER
            value: "nats"
          - name: MICRO_BROKER_ADDRESS
            value: "nats-cluster"
          - name: MICRO_REGISTRY
            value: "etcd"
          - name: MICRO_REGISTRY_ADDRESS
            value: "etcd-cluster-client"
      imagePullSecrets:
      - name: ap-south-1-ecr-registry

Dockerfile

  FROM alpine:latest
RUN apk --no-cache add make git go gcc libtool musl-dev
WORKDIR /go/src/
# Configure Go
ENV GOROOT /usr/lib/go
ENV GOPATH /go
ENV PATH /go/bin:$PATH

RUN mkdir -p ${GOPATH}/src ${GOPATH}/bin

COPY . .
COPY greeter-srv /go/src/
RUN make

RUN apk add ca-certificates && \
    rm -rf /var/cache/apk/* /tmp/* && \
    [ ! -e /etc/nsswitch.conf ] && echo 'hosts: files dns' > /etc/nsswitch.conf

ENTRYPOINT ["/greeter-srv"]

服务文件名greeter-srv

import (
    "github.com/micro/go-micro/v2"
)
func main() {
    service := micro.NewService(
        micro.Name("greeter")
    )
    service.Init()
    service.Run()
}

我已经使用上述docker文件构建，然后标记并推送到aws ecr，然后我在kubernetes yaml文件中使用了注册表故事。

Answer 1

stat /greeter-srv: no such file or directory"这是由于Dockerfile提到的WORKDIR /go/src/和ENTRYPOINT ["/greeter-srv"]这是错误的，应使用ENTRYPOINT ["/go/src/greeter-srv"]

Answer 2

您的Dockerfile文件导致了问题，请将入口点更改为/go/src/greeter-srv
