Ubuntu 20.04 + rstudio/r-builds

docker build -t r-sodium-ubuntu:latest .

On an M1 mac you also need --platform linux/amd64.

Size is about 600MB:

❯ docker inspect r-sodium-ubuntu:latest | grep -i size
        "Size": 594108867,
        "VirtualSize": 594108867,

Alpine + r-minimal

docker build -t r-sodium-minimal:latest -f Dockerfile-minimal .

This does not currently work on M1 with --platform linux/amd64, possibly because of a docker or qemu bug.

Size is about 40MB:

❯ docker inspect r-sodium-minimal:latest | grep -i size
        "Size": 39340717,
        "VirtualSize": 39340717,
