使用 Alpine - Unhandled 'error' 事件部署 Azure Function

Deploy Azure Function with an Alpine - Unhandled 'error' event

我想从最轻的 DockerFile 部署 Azure 功能(节点 and/or python)。

所以我需要能够 运行 az loginfunc.

目前唯一运行良好的是 2.27GB。


我用 alpines 尝试了很多可能性,但调用 func 总是失败。

示例:

FROM alpine:latest

RUN \
  apk update && \
  apk add bash make py3-pip && \
  apk add --virtual=build gcc libffi-dev musl-dev openssl-dev python3-dev make && \
  pip3 --no-cache-dir install -U pip && \
  pip3 install azure-cli && \
  apk del --purge build

RUN apk add --update nodejs nodejs-npm && \
    npm i -g azure-functions-core-tools@latest --unsafe-perm true

当我调用 func -h 时出现错误:

events.js:291
      throw er; // Unhandled 'error' event
      ^

Error: spawn /usr/local/lib/node_modules/azure-functions-core-tools/bin/func ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:268:19)
    at onErrorNT (internal/child_process.js:470:16)

  syscall: 'spawn /usr/local/lib/node_modules/azure-functions-core-tools/bin/func',
  path: '/usr/local/lib/node_modules/azure-functions-core-tools/bin/func',
  spawnargs: [ '-h' ]
}

FROM node:12-alpine # or 14-alpine

RUN \
  apk update && \
  apk add bash make py3-pip && \
  apk add --virtual=build gcc libffi-dev musl-dev openssl-dev python3-dev make && \
  pip3 --no-cache-dir install -U pip && \
  pip3 install azure-cli && \
  apk del --purge build

RUN npm i -g azure-functions-core-tools@3 --unsafe-perm true

与 alpine 相同的错误

FROM node:12

# Install base dependencies

#Install Azure CLI

RUN apt-get update \
    && apt-get install -y azure-functions-core-tools \
    && apt-get install azure-cli

最新的 azure-cli docker image 是用 Alpine 构建的。
不幸的是,我无法在 Alpine 上也 运行 azure-functions-core-tools...(参见 https://github.com/Azure/azure-functions-core-tools/issues/1358

但是,我设法从 ubuntu:20.04

开始制作了一个稍微“小”的图像

大小1.77GB,运行ning在GitlabCI没有问题(镜像也发布在我们的Gitlab中,所以pull还是蛮快的)

FROM ubuntu:20.04

RUN apt-get update && apt-get install -y ca-certificates curl apt-transport-https lsb-release gnupg

RUN curl -sL https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor | tee /etc/apt/trusted.gpg.d/microsoft.gpg
RUN AZ_REPO=$(lsb_release -cs) && \
    echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $AZ_REPO main" | tee /etc/apt/sources.list.d/azure-cli.list && \
    echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-$AZ_REPO-prod $AZ_REPO main" | tee /etc/apt/sources.list.d/dotnetdev.list

RUN apt-get update && apt-get install -y azure-cli azure-functions-core-tools-3

RUN curl -fsSL https://deb.nodesource.com/setup_12.x | bash && apt-get install -y nodejs

ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

对于任何试图使其不受大小影响的人,这里有一个使用官方 Microsoft 图像的解决方案,最终为 2.81 GB。基于 this issue comment 我能够让它工作。但是,它需要一些修改。这是我最终得到的结果:

# Dockerfile
FROM mcr.microsoft.com/azure-functions/python:2.0.12493-python3.6-buildenv

# Install azure-cli
RUN apt-get update
RUN apt-get install -y python3 python3-pip
RUN pip3 install azure-cli

# Install azure-functions-core-tools
RUN apt-get install -y build-essential
RUN apt-get install -y gcc musl-dev python3-dev libffi-dev libssl-dev cargo
RUN apt-get update && apt-get install -y ca-certificates curl apt-transport-https lsb-release gnupg
RUN curl -sL https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor | tee /etc/apt/trusted.gpg.d/microsoft.gpg
RUN AZ_REPO=$(lsb_release -cs) && \
RUN echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $AZ_REPO main" | tee /etc/apt/sources.list.d/azure-cli.list && \
RUN echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-$AZ_REPO-prod $AZ_REPO main" | tee /etc/apt/sources.list.d/dotnetdev.list
RUN apt-get update && apt-get install -y azure-functions-core-tools-3

您可以直接在本地使用它,但我需要它用于 GitLab CI 管道。所以首先你需要构建镜像并将其推送到 GitLab 容器存储库:

docker build -t registry.gitlab.com/GROUP/PROJECT/REPO/container-name .
docker push registry.gitlab.com/GROUP/PROJECT/REPO/container-name:latest

最后在 GitLab CI 管道中使用它:

# .gitlab-ci.yml
deploy:
  image: registry.gitlab.com/GROUP/PROJECT/REPO/container-name:latest
  stage: deploy
  tags:
    - dockerbuild-machine
  script:
    - pip3 install --target=".python_packages/lib/python3.8/site-packages" -r requirements.txt
    - az login --service-principal -u $AZURE_CLIENT_ID -p $AZURE_CLIENT_SECRET --tenant $AZURE_TENANT_ID
    - az account set --subscription $AZURE_SUBSCRIPTION_ID
    - func azure functionapp publish $FUNCTION_APP --no-build
