Get an SSH-enabled EVE-OS image

Prerequisites

• Docker application needs to be running

Procedures

Check if you have an SSH key and copy it:

cat ~/.ssh/id_rsa.pub

• If the output is blank, create a public key:

• ssh-keygen -b 2048 -t rsa

Add the custom configuration

1. Set up a directory for configuration settings:

   • mkdir /tmp/config

2. Add the SSH Public key to the "authorized_keys" file:

   • cat <PUBLIC_KEY_PATH> > /tmp/config/authorized_keys

3. Insert the ZEDEDA GUI FQDN into the server file by running: 
   

   • cat <<EOF > /tmp/config/server
     zedcloud.zededa.net
     EOF

   • zedcloud.zededa.net is being used in this example.
4. Add the configuration to the "global.json" file by running:

   • cat <<EOF > /tmp/config/global.json
     {
      "GlobalSettings": {
       "debug.enable.ssh": {
        "Key": "debug.enable.ssh",
        "ItemType": 3,
        "StrValue": "true"
       }
      }
     }
     EOF

Download and create the custom image installer

1. Execute the Docker command to generate the image file for the required EVE version. In the example below, the latest version will be downloaded.

   • docker run -v /tmp/config:/in lfedge/eve:latest -f raw installer_raw > installer-ssh.raw

2. Refer to Flash your EVE-OS image for guidance on installing EVE-OS onto your USB device.
