【问题描述】:
在 VS Code 中使用远程容器时,我想在不使用默认 sleep infinity 命令的情况下启动一个 Ubuntu 容器(稍后启动一个 Flask 服务器),以便稍后从主机访问该容器。
TL;DR
如果我从docker-compose.yml 中删除sleep infinity 命令,容器将无法启动,例如。 G。
Run: docker exec 12d95e1f14877bc4af7fa62e59f81b7ebf0f8983aa357eb077a09bf1951e4370 test -d /root/.vscode-server
Error response from daemon: Container 12d95e1f14877bc4af7fa62e59f81b7ebf0f8983aa357eb077a09bf1951e4370 is not running
.. 但是使用 sleep infinity 命令,我启动的 Flask 服务器无法从 devsettings.json 转发带有 appPort 的端口。

设置
VS Code 容器的镜像:Docker compose 中的 Docker
Dockerfile 中的图像:ubuntu:bionic
Dockerfile
FROM ubuntu:bionic
# Avoid warnings by switching to noninteractive
ENV DEBIAN_FRONTEND=noninteractive
# Docker Compose version
ARG COMPOSE_VERSION=1.24.0
...
# Configure apt and install packages
RUN apt-get update \
&& apt-get -y install --no-install-recommends apt-utils 2>&1 \
....
# Switch back to dialog for any ad-hoc use of apt-get
ENV DEBIAN_FRONTEND=dialog
我尝试在Dockerfile中添加ENTRYPOINT ["bash", "/bin/bash"],但是没有效果。
devsettings.json
{
"name": "Docker in Docker Compose",
"dockerComposeFile": "docker-compose.yml",
"service": "my-service",
"workspaceFolder": "/workspace",
// default command is "sleep infinity", can't use that as Flask should be accessible
"overrideCommand": false,
"appPort": ["5000:5000"],
"extensions": [
"peterjausovec.vscode-docker",
"ms-python.python"
],
"settings": {
"remote.extensionKind": {
"peterjausovec.vscode-docker": "workspace"
}
}
}
docker-compose.yml
version: '3'
services:
my-service:
build:
context: .
dockerfile: Dockerfile
volumes:
# Update this to wherever you want VS Code to mount the folder of your project
- ..:/workspace
# This lets you avoid setting up Git again in the container
- ~/.gitconfig:/root/.gitconfig
# Forwards the local Docker socket to the container.
- /var/run/docker.sock:/var/run/docker.sock
# Overrides default command so things don't shut down after the process ends.
command: sleep infinity

我没有看到您提到要在您的 docker-compose 文件中发布的任何端口。这可能是原因。

@7_R3X 一直以来我都认为
devsettings.json的appPort可以做到这一点,但如果再加上docker-compose.yml,显然不会。谢谢。随意创建一个答案。
