docker-compose.yml

因为已经使用了本地端口映射的方式，因此不对网络进行配置。

version: "2.2"

services:
  dev_host:
    container_name: dev_host
    image: rlyown/cdev_host
    security_opt: # options needed for gdb debugging
      - seccomp:unconfined
      - apparmor:unconfined
    ports:
      - 36000:36000 # ssh
      - 1234:1234 # gdb server
    volumes:
      - .:/home/bingo/Workdir
    privileged: true
#    networks:
#      extnetwork:
#        ipv4_address: 172.19.0.2
#
#networks:
#  extnetwork:
#    ipam:
#      config:
#        - subnet: 172.19.0.0/16
#          gateway: 172.19.0.1

辅助脚本

编写一个脚本来处理这些命令。

#!/usr/bin/env bash

action=$1

if [ "$action" = "enter" ]; then
    docker exec -it dev_host /bin/bash
elif [ "$action" = "up" ]; then
    docker-compose -f docker-compose.yml up -d
elif [ "$action" = "down" ]; then
    docker-compose down
fi

CLion 配置

在 CLion 的设置中，选择Build, Execution, Deployment中的Toolchains。

Credential 的配置如下（cdev_host 账户 bingo 对应的密码为123456）：

然后修改CMake，新增一个配置并将Toolchain选项配置为刚刚创建好的cdev-host-remote。

最后修改Deployment，连接的配置不用怎么修改。主要修改的是Mappings和Excluded Paths。

Mapping将本地的项目目录映射到远程主机的目录。

如果使用的是 Docker 的 mount 方式，即通过 Volume 方式共享文件夹的话，则不需要通过网络同步。所以将项目目录添加到Excluded Paths中。

问题

如果上述修改完之后出现了头文件找不到的情况，那么点击工具栏的Tools下的Resync with Remote Hosts选项，重新同步项目即可解决。（clion-and-remote-headers）
