如何在 github-action 中缓存 docker-compose 构建 [英] How to cache docker-compose build inside github-action

问题描述

有没有办法缓存 docker-compose 使其不会一次又一次地构建?这是我的操作工作流文件:

Is there any way to cache docker-compose so that it will not build again and again? here is my action workflow file:

name: Github Action
on:
  push:
    branches:
      - staging
jobs:
  test:
    runs-on: ubuntu-18.04

    steps:
      - uses: actions/checkout@v1

      - name: Bootstrap app on Ubuntu
        uses: actions/setup-node@v1
        with:
          node-version: '12'


      - name: Install global packages
        run: npm install -g yarn prisma


      - name: Install project deps
        if: steps.cache-yarn.outputs.cache-hit != 'true'
        run: yarn


      - name: Build docker-compose
        run: docker-compose -f docker-compose.test.prisma.yml up --build -d

我想缓存 docker 构建步骤.我试过使用 if: steps.cache-docker.outputs.cache-hit != 'true' then only build 但没有用.

I want to cache the docker build step. I have tried using if: steps.cache-docker.outputs.cache-hit != 'true' then only build but didn't work.

推荐答案

您所指的称为docker layer caching"，目前 GitHub Actions 尚不支持.

What you are referring to is called "docker layer caching", and it is not yet natively supported in GitHub Actions.

这在几个地方被广泛讨论，例如:

This is discussed extensively in several places, like:

• 缓存 docker 图像论坛帖子
• 缓存一个Docker 镜像内置于工作流论坛帖子
• 动作/缓存存储库中的 Docker 缓存问题

正如评论中提到的，有一些 3rd 方操作提供了这个功能(比如 这个)，但对于这样一个核心和基本功能，我会谨慎对待任何 GitHub 本身未正式支持的内容.

As mentioned in the comments, there are some 3rd party actions that provide this functionality (like this one), but for such a core and fundamental feature, I would be cautious with anything that is not officially supported by GitHub itself.
