This folder contains various scripts used at ER-Force
Some of these scripts use Docker.
In general, building these images requires at least Docker 19.03 and Docker BuildKit to be enabled.
Prefix docker commands with DOCKER_BUILDKIT=1 or take a look at the link to get instructions on how to enable it permanently.
We distribute V8 binaries as Docker images.
These images are available from Docker Hub at roboticserlangen/v8.
They are tagged as version-{x}-ubuntu-{y} where x is a counter we bump when changing something about V8 and y is the used Ubuntu Version (e.g. 20.04).
The build_docker_v8 script may be used to build Docker binaries.
Use it like this
$ ./build_docker_v8 <v8 version (internal)> <ubuntu version number (dd.dd)>
$ # e.g.
$ ./build_docker_v8 1 20.04This is the recommended way to build V8, since Docker provides a defined environment.
If it is required you build V8 yourself, take a look at the script to find the dependencies and adapt them to your system.
Providing the correct python binary is of particular importance.
V8 version 1 requires the global python binary (i.e. without suffix) to point to python2.
Depending on your distribution, the global python binary may point to python3 by default.
V8 version 2 requires a global python3 binary.
There is a script at data/scripts/package_docker_v8 that can be used to extract the V8 binaries out of such an image.
Use it like this
$ ./package_docker_v8 sometag
$ # e.g.
$ ./package_docker_v8 version-1-ubuntu-20.04
