After cloning the repo, perform the following tests to successfully setup a testing environment for FUSE-POSIX
$ cd ./fuse-posix/docker
$ docker build . -t ruciofs:test
$ docker-compose --file docker-compose.yml up -d
This shall build a docker image which you can check by performing
$ docker images | grep ruciofs | grep test
And you can confirm if the container is running by using
$ docker ps | grep dev_ruciofs_1
Now finally to begin testing we need a terminal window for our docker container, which you can get by executing
$ docker exec -it dev_ruciofs_1 /bin/bash
