我正在使用docker部署到fly.io服务器。前三个
FROM
命令是直接从文档中获取的。我需要在npm之外安装一些JavaScript包。为了方便起见,我添加了
javascripts
生成步骤,并尝试从此复制
javascript
将步骤构建到我的最终图像中。
Dockerfile
# syntax = docker/dockerfile:experimental
# Dockerfile used to build a deployable image for a Rails application.
# Adjust as required.
#
# Common adjustments you may need to make over time:
# * Modify version numbers for Ruby, Bundler, and other products.
# * Add library packages needed at build time for your gems, node modules.
# * Add deployment packages needed by your application
# * Add (often fake) secrets needed to compile your assets

我看到很多帖子展示了同样的问题,但在尝试了很多排列后,我没有找到解决方案。
