openfaas-playground

a vagrant project to get openfaas on your laptop

dependencies:

• virtualbox
• vagrant
• faas-cli
• docker binaries

TL;DR

vagrant up
vagrant status

Number of nodes

By default the cluster is made of 2 nodes, however you can update this on Vagrantfile to have multiples nodes

## config
numnodes = 5
## end config

Long description of usage

Once all the dependencies are installed, the following will happen:

vagrant will create a two (2) node multi-machine setup, and install docker and openfaas

then will create a swarm cluster, make the 2nd node join and install openfaas

vagrant up creates the vms vagrant status will display the current status of the vms and some information

0  (master) $ vagrant status

OpenFaas is configured to run at http://localhost:8080
once vagrant up finish try:
faas-cli list

to connect to docker daemon in the vm faas1 use:
export DOCKER_HOST=tcp://localhost:2375

then run:
docker node ls

building a new faas:
cd playground
faas-cli template pull
faas-cli new --list
faas-cli new hello --lang=dockerfile
faas-cli build -f hello.yml
faas-cli deploy -f hello.yml

go to the webpage and play: http://localhost:8080

Current machine states:

faas2                     running (virtualbox)
faas1                     running (virtualbox)

This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.

You can configure DOCKER_HOST variable so docker client on your computer can talk to the daemon on the vm

export DOCKER_HOST=tcp://localhost:2375
0  (master) $ docker node ls

desctiption of whats here

Vagrant is a tool to create repeatable environments so the developer can focus on the code instead of the infrastructure.

This project will do on start:

• download vm template
• configure ssh password less between the nodes
• deploy guest, 2 by default, you can scale to more
• install and configure docker
• create docker swarm cluster

on node1 faas1:

• install and deploy openfaas
• install openfaas-cli
• install portainer

extra stuff

portainer

portainer is a ui to visualise and manage docker hosts and integrate with swarm.

head to http://localhost:9000/ and setup the initial password
