Bootloader-Agent

Agent application for bootloader-web to serve as proxy for requests require L2 connectivity such as DHCP and in some cases TFTP for faster downloads.

Currently deep-deep alpha state.

Configuration

Currently there's the way to configure the agent via environment variables:

• AGENT_URL - required, url to be passed to deployed server to grab some data, such as download images, files, etc.
• API_TOKEN - required, bootloader-web API access token
• BOOTLOADER_URL - required, URL of bootloader-web instance
• BROKER_URL - required, URL of broker for celery
• DHCP_BOOT_FILENAME - filename to use for PXE boot. Builtin files are: pxelinux.0, lpxelinux.0 - default
• DHCP_NETMASK - netmask in IP form to serve by DHCP, example: 255.255.255.0
• DHCP_RANGE - <range_start>,<range_end>,<lease_duration> formated string
• DHCP_ROUTER - network router to serve by DHCP, example: 10.0.30.254
• DNSMASQ_OPTS - custom options to be passed to dnsmasq. Example:

  DNSMASQ_OPTS="--dhcp-option=option:ntp-server,192.168.0.5"
  

• LOG_FORMAT - log record format string. As Python template
• QUEUE - queue name generated by bootloader-web for particular location
• RUN_DHCP - true|false should we enable DHCP server or not
• RUN_HTTP - true|false should we enable HTTP server or not
• RUN_TFTP - true|false should we enable TFTP server or not
