Include container information in LXC MOTD at sign in

[cmyers-mieweb]

Objective:

• Display key container information (ports, protocols, hostname, IP, primary owner) in the message of the day (MOTD) upon LXC container sign in.

Tasks:

• Scrape relevant information from port_map.json for each container.
• Format and set this information as the MOTD for the corresponding LXC container.
• Ensure MOTD includes at least: ports, protocols, hostname, IP, and primary owner.
• Automate the MOTD update process to keep information current.

Priority: Low

Acceptance Criteria:

• MOTD reliably displays up-to-date container details on sign in.
• All required fields (ports, protocols, hostname, IP, primary owner) are present.
• The process is automated for future updates.

This issue has been resolved in #36

The following code block was added.

echo "Adding container MOTD information..."
scp 10.15.20.69:/etc/nginx/port_map.json /tmp/port_map.json
CONTAINER_INFO=$(jq -r --arg hn "$CONTAINER_NAME" '.[$hn]' /tmp/port_map.json)

if [ "$CONTAINER_INFO" != "null" ]; then
    HOSTNAME="$CONTAINER_NAME"
    IP=$(echo "$CONTAINER_INFO" | jq -r '.ip')
    OWNER=$(echo "$CONTAINER_INFO" | jq -r '.user')
    OS_RELEASE=$(echo "$CONTAINER_INFO" | jq -r '.os_release')
    PORTS=$(echo "$CONTAINER_INFO" | jq -r '.ports | to_entries[] | "\(.key): \(.value)"' | paste -sd ", " -)
    PROTOCOLS=$(echo "$CONTAINER_INFO" | jq -r '.ports | keys | join(", ")')

    cat <<EOF > /tmp/container_motd
