试图弄清楚如何为 docker 将此可执行文件容器化

Question

我在尝试创建一个暴露 Cloudflare's Tunnel executable for linux. Thus far I got to this stage with my docker image for it (image comes from https://github.com/jakejarvis/docker-cloudflare-argo/blob/master/Dockerfile)

的 docker 图像时遇到了困难

FROM ubuntu:18.04

LABEL maintainer="Jake Jarvis <jake@jarv.is>"

RUN apt-get update \
  && apt-get install -y --no-install-recommends wget ca-certificates \
  && rm -rf /var/lib/apt/lists/*

RUN wget -O cloudflared.tgz https://bin.equinox.io/c/VdrWdbjqyF/cloudflared-stable-linux-amd64.tgz \
  && tar -xzvf cloudflared.tgz \
  && rm cloudflared.tgz \
  && chmod +x cloudflared

ENTRYPOINT ["./cloudflared"]

在 official documentation for their kubernetes setup 之后，我通过以下方式将其作为 sidecar 添加到我的部署中：（这里 cloudflare-argo:5 是根据上面的 docker 文件构建的图像）

    - name: cloudflare-argo
      image: my-registry/cloudflare-argo:5
      imagePullPolicy: Always
      command: ["cloudflared", "tunnel"]
      args:
        - --url=http://localhost:8080
        - --hostname=my-website
        - --origincert=/etc/cloudflared/cert.pem
        - --no-autoupdate
      volumeMounts:
        - mountPath: /etc/cloudflared
          name: cloudflare-argo-secret
          readOnly: true
      resources:
        requests:
          cpu: "50m"
        limits:
          cpu: "200m"
  volumes:
    - name: cloudflare-argo-secret
      secret:
        secretName: my-website.com

然而，一旦我部署，我的 pod 就会出现 CrashLoopBackOff 错误，并出现以下 kubectl describe 输出

Created container cloudflare-argo

Error: failed to start container "cloudflare-argo": Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"cloudflared\": executable file not found in $PATH": unknown

Answer 1

在 dockerfile 中它是 ./cloudflared，所以那将是：

      command:
        - ./cloudflared
        - tunnel
        - --url=http://localhost:8080
        - --hostname=my-website
        - --origincert=/etc/cloudflared/cert.pem
        - --no-autoupdate

（也没有理由同时使用command和args，只选择一个，如果你放弃第一个项目然后使用args）。

Answer 2

在您的 Dockerfile 中，将 cloudflared 二进制文件从当前 WORKDIR.

移动到 /usr/local/bin 文件夹而不是运行

  && chmod +x cloudflared \
  && mv cloudflared /usr/local/bin

ENTRYPOINT ["cloudflared"]
