Create an SSH Enabled EVE-OS Image

Requirements

• Pre-generated base64-encoded public/private key. You can run the command below to generate a new key pair: ssh-keygen -b 2048 -t rsa
• Linux or Mac with Docker installed and an internet connection.

Create file structure for ISO

• Create a config directory for custom options:mkdir /tmp/config
• Place the SSH Public key in authorized_keys:cat <path to public key> > /tmp/config/authorized_keys
• Place Edge Cloud FQDN in the server (zedcloud.zededa.net)

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

• Place the settings to enable the ssh server in the global.json file in the config/GlobalConfig directory.

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

Create and deploy installer ISO image

Run docker to create this ISO with the eve version needed. 8.5.3, the currently supported version, is provided in the following example.

docker run -v /tmp/config:/in lfedge/eve:8.5.3-kvm-amd64 installer_iso>installer.iso

Mount the installer.iso as a CD image and image device.

Verification

SSH to the device using the private key.

ssh -i ./private_key root@<device IP/FQDN>
