The Container Storage Interface\n(CSI) is a proposed new industry standard for cluster-wide volume plugins.\n“Container Storage Interface” (CSI) enables storage vendors (SP) to develop a\nplugin once and have it work across a number of container orchestration (CO)\nsystems.\n\n## Demo of GlusterFS CSI driver to create and delete volumes on GD2 Cluster\n\n[![GlusterFS CSI driver Demo](https://asciinema.org/a/195024.png)](https://asciinema.org/a/195024)\n\n## Building GlusterFS CSI driver\n\nThis repository contains the source and a Dockerfile to build the GlusterFS CSI\ndriver. The driver is built as a multi-stage container build. This requires a\nrelatively recent version of Docker or Buildah.\n\nDocker packages can be obtained for\n[CentOS](https://docs.docker.com/install/linux/docker-ce/centos/),\n[Fedora](https://docs.docker.com/install/linux/docker-ce/fedora/) or other\ndistributions.\n\nTo build, ensure docker is installed, and run:\n\n1. Get inside the repository directory\n\n```\n[root@localhost]# cd gluster-csi-driver\n```\n\n1. Build the glusterfs-csi-driver container\n\n```\n[root@localhost]# ./build.sh\n```\n\n## Testing GlusterFS CSI driver\n\n### Deploy kubernetes Cluster\n\n### Deploy a GD2 gluster cluster\n\n### 1.
