Mount EFS storage on EC2 instance and build Caddy for online file browsing

Pre-requisites

  1. EFS storage has been created, and the application can successfully write logs to EFS.
  2. An EC2 instance: to mount the EFS storage directory and setup Caddy.

Step 1: Install the Amazon EFS Client on the EC2 Instance

  1. Access the instance’s terminal via (SSH) and log in with the appropriate username.
  • If the EC2 instance system is an Amazon Linux system
  1. Run the following command to install the amazon-efs-utils package.
   sudo yum install -y amazon-efs-utils
  • If the EC2 instance system is Debian or Ubuntu
  1. To build and install the Debian packages:
    $ sudo apt-get update
    $ sudo apt-get -y install git binutils rustc cargo pkg-config libssl-dev
    $ git clone https://github.com/aws/efs-utils
    $ cd efs-utils
    $ . /build-deb.sh
    $ sudo apt-get -y install . /build/amazon-efs-utils*deb

If your Debian distribution does not provide rust or cargo packages, or if your distribution provides versions earlier than 1.68, then you can install rust and cargo via rustup:

    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
    . "$HOME/.cargo/env"
  1. If you have any problems with the installation please refer to documentation

Step 2: Create a directory to mount EFS

  1. Create the directory efs as a file system mount point with the following command
sudo mkdir efs
  1. Mount EFS using the following command
sudo mount -t efs -o tls fs-0bbb30c3d8cefacb1:/ efs

Note: fs-0bbb30c3d8cefacb1 is the EFS ID.

Step 3: Installing Caddy

The following are examples of Ubuntu installation commands only, for other systems refer to documentation

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring .gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

Step 4: Configure CaddyFile and start Caddy

  1. Create a Caddyfile file and enter the following, as described in documentation
vpn.great-way.link {
        root * /home/admin/efs
        file_server browse
        basic_auth {
                admin $2a$14$NLRgL1aezQg6IkDQCWnESeUo6U1RRNqsN6mSk.9EvhRBTqq39Tdc2
        }
}

**Note: **.

  • vpn.great-way.link is the domain name pointing to the IP of this EC2 instance, which Caddy automatically configures for SSl certificates and HTTPS access.
  • root * /home/admin/efs where /home/admin/efs is the directory where EFS is mounted.
  • file_server browse is set as the file browse service.
  • basic_auth enables basic authentication, admin is the username, $2a$14$NLRgL1aezQg6IkDQCWnESeUo6U1RRNqsN6mSk.9EvhRBTqq39Tdc2 is the command caddy hash-password -p password. For the encrypted password, refer to the documentation basic_auth caddy hash-password /docs/command-line#caddy-hash-password)

Step 5: Access the configured domain name and browse the file online

Open the vpn.great-way.link address in your browser and enter your username and password to access the

caddy
