Massive credits go to one of my best friends, and mentor Jonathan "stamp" G for all the help, coaching and lessons during this project. Without your support this project would never have been a reality.

VMware #clarity-ui channel for being super helpful with newbie questions about clarity!

go-via is a single binary, that when executed performs the tasks of dhcpd, tftpd, httpd, and ks.cfg generator, with a angular front-end, and http-rest backend written in go, and sqlite for persisting.

The old version of VIA had some things it didn't support which made it hard to run in enterprise environments. go-via brings added support for the following.

1. IP-Helper , you can have the go-via binary running on any network you want and use RFC 3046 IP-Helper to relay DHCP requests to the server.
2. UEFI , go-via does not support BIOS, but does support UEFI and secure-boot. BIOS may be added in the future.
3. Virtual environments, it does not block nested esxi host deployment.
4. HTTP-REST, everything you can do in the UI, you can do via automation also.
5. Options to perform all prerequisites for VMware Cloud Foundation 4.x/5.x

install docker-ce (https://docs.docker.com/engine/install/ubuntu/)

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

install latest docker-compose,

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose

Option A: create the following docker-compose.yaml file to not specify a config file (dhcpd will serve on all interfaces)

version: "3.9"
services:
  go-via:
    image: maxiepax/go-via:latest
    network_mode: host
    volumes:
      - ./tftp:/go/tftp
      - ./database:/go/database
      - ./config:/go/config
      - ./cert:/go/cert
      - ./secret:/go/secret

Option B: or create this docker-compose.yaml to specify a config file, and place config in ./config/config.json

version: "3.9"
services:
  go-via:
    image: maxiepax/go-via:latest
    network_mode: host
    volumes:
      - ./tftp:/go/tftp
      - ./database:/go/database
      - ./config:/go/config
      - ./cert:/go/cert
      - ./secret:/go/secret
    command: -file /go/config/config.json

Example config file

{
    "network": {
        "interfaces": ["ens224", "ens192"]
    },
    "port": 443
}

now start the container

sudo docker-compose up -d

Most linux distributions should work, this has been tested on Ubuntu 20.20.

#wget the release you want to download, e.g go-via_.<release>_linux_amd64.tar.gz
wget https://github.com/maxiepax/go-via/releases/download/<release>/go-via_.<release>_linux_amd64.tar.gz


#untar/extract it
tar -zxvf go-via_.<release>_linux_amd64.tar.gz

This will extract the files README.MD (this document) and go-via binary.

Optional: example config files.

Multi interface, and custom port.

{
    "network": {
        "interfaces": ["ens224", "ens192"]
    },
    "port": 443
}

Single interface, default port 8443

{
    "network": {
        "interfaces": ["ens224"]
    }
}

Now start the binary as super user, (optionally: pointing to the config file.)

#start the application with default settings
sudo ./go-via

#start the application with normal debug level
sudo ./go-via -file config.json

#start the application with verbose debug level
sudo ./go-via -file config.json -debug

Example systemd.service config file

You should be greeted with the following output.

with Ubuntu 20.20 installed, do the following: install golang 1.16.x compiler

sudo snap install go --classic

install npm

sudo apt-get install npm

install angular-cli

sudo npm install npm@latest -g
sudo npm install -g @angular/cli

start two terminals:

terminal 1:

mkdir ~/go
cd ~/go
git clone https://github.com/maxiepax/go-via.git
cd go-via
go run *.go

terminal 2:

cd ~/go-via/web
npm install
# to only allow localhost access to gui:
ng serve
# to allow anyone access to gui:
ng serve --host 0.0.0.0

To troubleshoot, enable debugging.

Option 1: Docker Container. Append -debug to command.

command: -debug
or
command: -file /go/config/config.json -debug

Option 2: Source or Binary. Append -debug to command

./go-via -debug
