Instructions for locally reproducing the CI sandbox

git clone https://github.com/JuliaCI/rootfs-images.git
cd rootfs-images
julia --project -e 'import Pkg; Pkg.instantiate()'
julia --project test_rootfs.jl --treehash $ROOTFS_TREEHASH

You get the values of ROOTFS_TREEHASH by looking at the types.jl file.

Note: if you are looking at the CI run for a PR, you should get the ROOTFS_URL and ROOTFS_TREEHASH values from the types.jl on the PR branch (instead of the master branch).

For more details, see the rootfs-images repository.
