Static Persistent Volumes

Self hosted nfs ( network file system ) that are not dependent on any cloud provider.

Creating a networked file system

File system present somewhere on host machine open on a network.

Step 1 : Starting NFS ( for testing )

• Create EC2 machine

# ssh into EC2 machine
ssh -i ~/.ssh/id_rsa_aws [email protected]

• Install Docker on EC2 machine

• Create docker compose file to start NFS server inside docker container in EC2 achine

vi docker-compose.yml

docker-compose.yml

version: '3.7' # Docker Compose Version
services: # Define a service named nfs-server
  nfs-server: # Ecah service is a container managed by docker compose
    image: itsthenetwork/nfs-server-alpine:latest # Docker image with NFS Server (system that allows multiple containers to share file over a network )
    privileged: true # Give extra permissions to this container since NFS requires it
    environment:
      SHARED_DIRECTORY: /exports # this dir will be exposed over NFS
    volumes:
      - /home/ubuntu/data:/exports:rw # mount local dir ./data into container at exports with read write permission
    ports:
      - '2049:2049'
    restart: unless-stopped # Restart if docker crashes

• Create data folder on EC2 machine that will be mounted to docker container at /exports

mkdir data

• Start docker compose file

sudo docker compose up

This will start networked file system on port 2049. Obviously you can’t visit port 2049 since it not an http request but your file is now exposed via NFS.
