Build OpenWrt images in a Docker container. This is sometimes necessary when building OpenWrt on the host system fails, e.g. when some dependency is too new. The docker image is based on ubuntu 20.04 (focal).
Build tested:
- OpenWrt-21.02.3
- OpenWrt-19.07.10
- OpenWrt-18.06.9
A smaller container based on Alpine Linux is available in the alpine branch. But it does not build the old LEDE images.
- Docker installed
- running Docker daemon
- build Docker image:
git clone https://github.com/kayuii/docker-openwrt-builder.git
cd docker-openwrt-builder
docker build -t openwrt_builder .
Now the docker image is available. These steps only need to be done once.
Create a build folder and link it into a new docker container:
mkdir ~/mybuild
docker run -v ~/mybuild:/home/ubuntu -it openwrt_builder /bin/bash
or
mkdir ~/mybuild
docker run --rm -d --name openwrt_builder -p 22022:22 -v ~/mybuild:/home/ubuntu openwrt_builder
docker exec -it openwrt_builder /bin/bash
import key
mkdir .ssh
echo "your pubkey" >> ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys
ssh
ssh ubuntu@127.0.0.1 -p 22022
In the container console, enter:
git clone https://git.openwrt.org/openwrt/openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig
make -j4
After the build, the images will be inside ~/mybuild/openwrt/bin/target/.
