Read the details in my blog (in Chinese) | 中文教程

Usage

Pull or build image

Pull image from docker hub.
```
docker pull p3terx/openwrt-build-env
```

Build image.

docker build -t p3terx/openwrt-build-env github.com/P3TERX/openwrt-build-env

Run container

docker run \
    -itd \
    --name openwrt-build-env \
    -h P3TERX \
    -p 10022:22 \
    -v ~/openwrt:/home/user/openwrt \
    p3terx/openwrt-build-env

Set the mount directory file permissions

Enter the id command to check UID and GID
```
$ id
uid=1001(p3terx) gid=1002(p3terx)
```

Modify the UID and GID

docker exec openwrt-build-env sudo usermod -u 1001 user
docker exec openwrt-build-env sudo groupmod -g 1002 user

Modify the file ownership

docker exec openwrt-build-env sudo chown -hR user:user .

Restart container
```
docker restart openwrt-build-env
```

SSH security settings

The default SSH user name and password is user. If you are making the container accessible from the internet you'll probably want to secure it bit. You can do one of the following two things after launching the container:

Change password:

docker exec -it openwrt-build-env sudo passwd user

Don't allow passwords at all, use keys instead:

docker cp ~/.ssh/authorized_keys openwrt-build-env:/home/user/.ssh
docker exec openwrt-build-env sudo chown user:user /home/user/.ssh/authorized_keys
docker exec openwrt-build-env sudo sed -i '/PasswordAuthentication /c\PasswordAuthentication no' /etc/ssh/sshd_config
docker restart openwrt-build-env

Enter container

Enter from the host.
```
docker exec -it openwrt-build-env zsh
```
Connect via SSH.
```
ssh user@IP -p 10022
```
