Question

我正在使用VSCode Devcontainer开发微服务应用程序，并且一直在使用Java Devcontainer而不出现问题。但是，鉴于项目的微服务性质，我还需要执行其他容器（例如，postgres db）。这是我用来开发的唯一容器，用于安装Java特定的扩展，智能感知工作等。我在本地计算机上没有此容器，也不想拥有。仅当在容器上编码时。

现在，我做了一些研究，将Devcontainer的使用转移到docker-compose上，不仅启动Java devcontainer，而且启动数据库。一切似乎都可以正常运行。但是，开发容器将始终以代码137退出，我不知道为什么。

代码的结构如下：

|.devcontainer
|--devcontainer.json
|--Dockerfile
|--docker-compose.yaml
|.git
|actionable-content
|--(my module code)
|db
|--Dockerfile
|--init.sql
|(...)

这是容器构建命令的输出：

[6706 ms] Shell server terminated (code: 137, signal: null)


[6747 ms] Remote-Containers server terminated (code: 137, signal: null).

我怀疑问题可能出在扩展程序安装过程中，但我不确定。无论如何，我从devcontainer.json + Dockerfile here（要点）的组合转到devcontainer.json + docker-compose.yaml + Dockerfile的组合， here（另一个要点）。

什么可能导致上述错误？我真的迷路了，因为我没有理由。另外，我怀疑我需要初始版本的runArgs，但使用docker-compose模式时似乎不支持它们。

谢谢

Answer 1

好吧，对于最终来到这里的任何人来说，这就是我改变的方法：

在我的docker-compose.yaml上添加了以下内容：

volumes:
  # Make the first part whatever your working dir is
  - ..:/workspace:cached
  - "${HOME}/.ssh:/root/.ssh-localhost:ro"
command: /bin/sh -c "while sleep 1000; do :; done"

我在Dockerfile的末尾也添加了CMD：

CMD [ "sleep", "infinity" ]

然后重建图像，它应该可以工作。

另外，关于runArgs，我将其添加到了docker-compose.yaml文件中：

# Uncomment the next four lines if you will use a ptrace-based debugger like C++, Go, and Rust.
cap_add:
  - SYS_PTRACE
security_opt:
  - seccomp:unconfined

这些添加/修改也应该为您解决问题

Answer 2

这是我一直在任何Dockerfile中使用VSCode的命令：

# Keep container running (for use in VSCode)
CMD [ "tail", "-f", "/dev/null" ]

远程开发容器-迁移至Docker Compose
