容器的Github操作缓存问题

Question

我有一个快速问题，但找不到相关文档(也许这是不可能的(我如何从容器中检索已构建的内容(如下图所示(：

prod-dependencies:
name: Production Dependencies
runs-on: ubuntu-20.04
container: elixir:1.11-alpine
env:
MIX_ENV: prod
steps:
- name: Checkout
uses: actions/checkout@v2
with:
fetch-depth: 0
- name: Retrieve Cached Dependencies
uses: actions/cache@v2
id: mix-prod-cache
with:
path: |
${{ github.workspace }}/deps
${{ github.workspace }}/_build
key: PROD-${{ hashFiles('mix.lock') }}
- name: Install Dependencies
if: steps.mix-prod-cache.outputs.cache-hit != 'true'
run: |
apk add build-base rust cargo
mix do local.hex --force, local.rebar --force, deps.get --only prod, deps.compile

我需要在Alpine上进行构建，因为我是在Alpine中进行部署的，而且一些库对于Erlang虚拟机的工作来说是不同的。

因此，这里是我构建依赖项的地方，我想将它们放在缓存中用于后续作业，但缓存从未填充。根据DocGitHub的说法，装载一个带有容器的卷来检索工件，但我一定错过了使用它

非常感谢你的帮助。

以下是Elixir应用程序的Github工作流示例，该应用程序具有使用action/cache@v2的Postgres数据库。请注意，它定义了两个单独的步骤来恢复deps和_build目录。在这个工作流程中，mix deps.get和mix compile步骤总是运行的：如果恢复了缓存，它们应该执行得非常快。

改编自此工作流程
