docker-buildenv
Tools for build environment on Docker.
You can build software on any Docker containers that include buildenv (docker-buildenv), like:
$ mkdir build $ cd build $ din anyakichi/yocto-builder builder@build:/build$ extract builder@build:/build$ setup builder@build:/build$ build
din is the script included in this repository. You need to copy it to a directory in PATH before using buildenv.
$ curl -o ~/.local/bin/din \
https://raw.githubusercontent.com/anyakichi/docker-buildenv/master/din.sh
extract, setup, and build are commands prepared by buildenv.
- extract
- Download and extract source trees.
- setup
- Setup build environment.
- build
- Build software.
Normally, extract is required only once, so you can use the container after the second:
$ cd build $ din anyakichi/yocto-builder builder@build:/build$ setup builder@build:/build$ build
Developing and Building
docker-buildenv is just the environment for building, not editing. We normally open two terminal windows or tabs, one is for docker-buildenv and the other is for the host environment, and we edit source files in the host environment, then switch to docker-buildenv and build software over and over.
Build environment for a specific software often requires a specific OS version, which is old and inconvenient. We can always use the latest and customized version of a text editor and other development tools when we develop with docker-buildenv.
Executable manual
docker-buildenv is also for executable manual. Development manuals usually include processes like:
- Install a specific OS to your machine.
- Install some packages.
- Download and extract a source tree.
- Execute build commands.
docker-buildenv assumes that 1. and 2. are in Dockerfile, 3. is in /etc/buildenv.d/extract.txt and 4. is in /etc/buildenv.d/build.txt.
The extract command just filter the lines starts with prompt ($) from extract.txt and simply execute it. So you can execute the manual if it is put in the container.
