如何将 Visual Studio Code 扩展重新打包到具有自己的依赖项集的 Che-Theia 插件中

Question

我正在尝试将 Visual Studio Code 扩展重新打包到 Eclipse Che 作为 Che-Theia 插件。 plug-in 从 Ansible 文件中提取源代码指标，如下所示：

它通过执行一个用 Python 编写的工具的命令行来实现，即ansiblemetrics，该工具必须安装在用户的环境中。 因此，我无法将该依赖项添加到 VSC 扩展的 package.json。相反，用户必须将它安装在 Eclipse Che 工作区上。尽管如此，我希望 Eclipse Che 用户在使用扩展时不需要安装依赖项。容器看起来不错。

我有以下 Eclipse Che DevFile

Eclipse Che DevFile

apiVersion: 1.0.0
metadata:
  name: python-bd3zh
attributes:
  persistVolumes: 'false'
projects:
  - name: python-hello-world
    source:
      location: 'https://github.com/che-samples/python-hello-world.git'
      type: git
      branch: master
components:
  - type: chePlugin
    reference: 'https://raw.githubusercontent.com/radon-h2020/radon-plugin-registry/master/radon/radon-defect-predictor/latest/meta.yaml'
    alias: radon-dpt

Eclipse docs 表示“要将 VS Code 扩展重新打包为具有自己的一组依赖项的 Che-Theia 插件，请将依赖项打包到容器中。” 可以在 spec keyword 下的 chePlugin 引用的元数据中添加容器：

spec:
  containers:                                                   
    - image:                                                    
      memoryLimit:                                              
      memoryRequest:                                            
      cpuLimit:                                                 
      cpuRequest:

因此，我的插件的元数据（meta.yaml）如下：

meta.yaml

apiVersion: v2
publisher: radon
name: radon-defect-predictor
version: 0.0.5
type: VS Code extension
displayName: RADON-h2020 Defect Predictor
title: A Defect Predictor for Infrastructure-as-Code by RADON
description: A customized extension for analyzing the defectiveness of IaC blueprints
icon: https://www.eclipse.org/che/images/logo-eclipseche.svg
repository: https://github.com/radon-h2020/radon-defect-prediction-plugin
category: Other
spec:
  containers:                                                   
    - image: stefadp/radon-dpt-plugin
  extensions:
    - https://raw.githubusercontent.com/radon-h2020/radon-defect-prediction-plugin/master/radon-defect-predictor-0.0.5.vsix

镜像 stefadp/radon-dpt-plugin 是基于以下 Dockerfile 构建的：

Dockerfile

FROM ubuntu:latest

RUN apt-get update \
  && apt-get install -y python3-pip python3-dev \
  && cd /usr/local/bin \
  && ln -s /usr/bin/python3 python \
  && pip3 install --upgrade pip

RUN pip3 install ansiblemetrics

但是，当我在 Eclipse Che 中运行工作区时，我观察到以下错误：

你有什么提示吗？

Answer 1

您必须自定义 docker 映像才能在 sidecar 容器中工作。作为一个例子，你可以看看已经在 Che in sidecars 中使用的图像：https://github.com/eclipse/che-plugin-registry/blob/master/CONTRIBUTE.md#sidecars

尝试创建下一个结构：

radon
  etc
    entrypoint.sh
  Dockerfile

entrypoint.sh的内容是：

#!/bin/sh
set -e
set -x

USER_ID=$(id -u)
export USER_ID
GROUP_ID=$(id -g)
export GROUP_ID

if ! whoami >/dev/null 2>&1; then
    echo "${USER_NAME:-user}:x:${USER_ID}:0:${USER_NAME:-user} user:${HOME}:/bin/sh" >> /etc/passwd
fi

# Grant access to projects volume in case of non root user with sudo rights
if [ "${USER_ID}" -ne 0 ] && command -v sudo >/dev/null 2>&1 && sudo -n true > /dev/null 2>&1; then
    sudo chown "${USER_ID}:${GROUP_ID}" /projects
fi

exec "$@"

Dockerfile 是：

FROM ubuntu:latest

ENV HOME=/home/theia

RUN mkdir /projects ${HOME} && \
    # Change permissions to let any arbitrary user
    for f in "${HOME}" "/etc/passwd" "/projects"; do \
      echo "Changing permissions on ${f}" && chgrp -R 0 ${f} && \
      chmod -R g+rwX ${f}; \
    done

RUN apt-get update \
  && apt-get install -y python3-pip python3-dev \
  && cd /usr/local/bin \
  && ln -s /usr/bin/python3 python \
  && pip3 install --upgrade pip

RUN pip3 install ansiblemetrics

ADD etc/entrypoint.sh /entrypoint.sh
ENTRYPOINT [ "/entrypoint.sh" ]
CMD ${PLUGIN_REMOTE_ENDPOINT_EXECUTABLE}

然后构建这个 Dockerfile 并在你的插件中使用它meta.yaml
