While here, fix the `docker build` command: the images are named `build_${IMG}`
while the ci files are just `ci/${IMG}`, no `build_` prefix.

# Keeping CI images up to date
|
|
|
|
## Re-building an image after updating the docker file
|
|
|
|
Run `docker build -t snmallocciteam/build_${IMG}:latest -f ci/${IMG} .` from the root of the repo,
|
|
where `$IMG` is the image you want to rebuild, for example `linux_x64`
|
|
|
|
If you are building a multiarch image, ie. an image targeting an architecture other than
|
|
the one you are running, you will need to install the qemu handler before you can build:
|
|
`sudo docker run --rm --privileged multiarch/qemu-user-static:register --reset`
|
|
|
|
## Testing locally
|
|
|
|
Having built a docker image, you can build your current tree therein with
|
|
|
|
docker run --rm -u $(id -u) -v ${PWD}:/opt:ro snmallocciteam/build_${IMG}:latest \
|
|
sh -c "cd /tmp; CC=clang-10 CXX=clang++-10 BUILD_TYPE=Debug SNMALLOC_SRC=/opt /opt/ci/scripts/build.sh && (cd build; ninja test)"
|
|
|
|
## Pushing the updated docker image to Docker Hub
|
|
|
|
Run `docker push snmallocciteam/$IMG:latest`
|
|
|
|
