Dockerized LEDE/OpenWRT compile environment

A simple docker image to compile LEDE/OpenWRT images from source.

Look here for a simpler version which uses the LEDE/OpenWRT imager builder, which uses pre-compiled packages to build the actual image.

Usage

Dockerized LEDE/OpenWRT compile environment.

Usage: $1 COMMAND [OPTIONS] 
  COMMAND is one of:
    build-docker-image- build docker image
    shell             - start shell in docker container

  OPTIONS:
  -o WORK_DIR         - working directory 
  --skip-sudo         - call docker directly, without sudo

Example:
  ./builder.sh shell

First build the docker image with ./builder.sh build-docker-image, then put your source files in the workdir/ directory and start the acutal container with the LEDE build environment with ./builder.sh shell.

The last command will open a shell in the docker container with local the workdir/ mounted to the directory /workdir in the container. Since workdir is externally mounted, it's contents will survive container restarts.

Example build session

Create the the docker image and start a container as described above. This will take you straight into a shell in the container, with the local workdir directory mounted as a volume to /workdir. On success, you'll see a prompt like builder@567cbabfb36b:/workdir$. Now execute the following commands to build LEDE from source (see this page for more details):

git clone https://git.lede-project.org/source.git lede && cd lede
./scripts/feeds update -a
./scripts/feeds install -a
make defconfig
make menuconfig
make

The resulting images can be found in workdir/lede/bin/target.
