dmorn / flexi

KIM needs a small tool to run stuff on some specific hardware, with auto-scaling.

flexi

docker session

on one terminal:

% docker run -p 564:564 --env-file docker.env --privileged jecoz/flexi

or, if you want to persist mounts across sessions (preferred way), create a Docker volume and issue

% docker run -p 564:564 --env-file docker.env --privileged --mount src=<desired volume name>,dst=/mnt jecoz/flexi

on another terminal:

% 9 mount localhost:9pfs mnt
% cat mnt/clone

% cat testdata/input.1.json > mnt/0/spawn

Notes about deploying to AWS

• flexi needs to be hosted in an environment that allows it to "mount", hence not Fargate but rather ECS with priviledged flag enabled (hang on we're working on it. See issue #10)
