我正在嘗試從我的容器中運(yùn)行一些 kubectl 命令。package mainimport (    "fmt"    "os/exec")    op, err := GetPods("test-containers", "qa")    if err != nil {        fmt.Printf("\nError: %v", err)    }    fmt.Printf(op)func GetPods(name, namespace string) (podName string, err error) {    fmt.Println("Get pod names ....")    cmd := "kubectl get pods -n " + namespace + " -o wide | grep " + name + " | awk '{print $1}' "    cmnd, err := exec.Command("sh", "-c", cmd).Output()    if err != nil {        fmt.Println("Failed to find pod name." + string(cmnd))    }    podName = string(cmnd)    return}我的多級(jí) Dockerfile 基于 Alpine3.6 并安裝了 kubectl 二進(jìn)制文件。FROM alpine:3.6RUN apk add --update curl wget ca-certificates unzip python py-pip openssl bash && \    apk --update add openssh-client && \    apk --update add --virtual build-dependencies python-dev libffi-dev openssl-dev build-base && \    apk add --no-cache --upgrade bash && \    pip install --upgrade pip cffi && \    pip install awscli && \    wget  https://storage.googleapis.com/kubernetes-release/release/v1.15.1/bin/linux/amd64/kubectl && \    chmod u+x kubectl && mv kubectl /bin/kubectl && \    apk del build-dependencies && \    rm -rf /var/cache/apk/*ENV HOME=/go/app/WORKDIR /go/appCOPY --from=go-container-build /go/app/ .ENTRYPOINT ["bash"]當(dāng)我將容器作為 pod 運(yùn)行并嘗試執(zhí)行命令時(shí)；我總是遇到以下錯(cuò)誤：cmd:  kubectl -n qa get pods -o wide | grep test-containers | awk '{print $1}'Failed to find pod name.exit status 2/bin/sh: illegal option -我也嘗試過使用 os.exec.Command() exec.Command("/bin/sh", "-c", cmd)，exec.Command("/bin/bash", "-c", cmd)但我遇到了類似的錯(cuò)誤。Failed to find pod name.exit status 2/bin/sh: illegal option -我也直接試過cmnd := exec.Command(cmd)；但我得到了錯(cuò)誤：Failed to find pod name.fork/exec kubectl -n qa get pods -o wide | grep test-containers | awk '{print $1}':executable file not found in $PATH我已經(jīng)在容器中安裝了 bash，當(dāng)我直接在容器 shell 上運(yùn)行命令時(shí)，我總是得到輸出。
