Docker OpenWrt Builder
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 Debian 10 (Buster).
Build tested:
- OpenWrt-21.02.2
- OpenWrt-19.07.8
- 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.
Prerequisites
- Docker installed
- running Docker daemon
- build Docker image:
git clone https://github.com/strongkill/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.
Usage GNU/Linux
Create a build folder and link it into a new docker container:
mkdir ~/mybuild
docker run -v ~/mybuild:/home/user -it openwrt_builder /bin/bash
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/.
Usage MacOSX
OpenWrt requires a case-sensitive filesystem while MacOSX uses a case-insensitive filesystem by default.
Create a disk image:
hdiutil create -size 20g -fs "Case-sensitive HFS+" -volname OpenWrt OpenWrt.dmg
hdiutil attach OpenWrt.dmg
Then run:
docker run -v /volumes/openwrt:/home/user -it openwrt_builder /bin/bash
