如何將 Visual Studio Code 擴展重新打包到具有自己的依賴項集的 Che-Theia 插件中

Question

我正在嘗試將 Visual Studio Code 擴展重新打包到 Eclipse Che 作為 Che-Theia 插件。 該插件從 Ansible 文件中提取源代碼指標，如下所示：

它通過執行一個用 Python 編寫的工具（即ansiblemetrics ）的命令行來實現，該工具必須安裝在用戶的環境中。 因此，我無法將該依賴項添加到 VSC 擴展的 package.json。 相反，用戶必須將其安裝在 Eclipse Che 工作區上。 盡管如此，我希望 Eclipse Che 用戶在使用擴展時不需要安裝依賴項。 一個容器看起來通往 go。

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 文檔說“要將 VS Code 擴展重新打包為帶有自己的一組依賴項的 Che-Theia 插件，package 將依賴項打包到一個容器中。” 容器可以添加到 chePlugin 引用的元數據中的spec關鍵字下：

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

因此，我的插件的元數據（ meta.yaml ）如下：

元.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

其中圖像stefadp/radon-dpt-plugin基於以下 Dockerfile 構建：

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，當我在 Eclipse Che 中運行工作區時，我觀察到以下錯誤：

你有什么提示嗎？

Answer 1

您必須自定義 docker 映像才能在 sidecar 容器中工作。 作為示例，您可以查看已在 Sidecars 中的 Che 中使用的圖像： https://github.com/eclipse/che-plugin-registry/blob/master/CONTRIBUTE.md#sidecars

嘗試創建下一個結構：

radon
  etc
    entrypoint.sh
  Dockerfile

entrypoint.sh的內容是：

#!/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}

然后構建這個 Dockerfile 並在你的插件meta.yaml中使用它
