Many things are still missing here, including a proper documentation. Please stay nice, it is a volunter project. Feel free to open pull/merge requests to improve it. Thanks.

Our abstraction stack

We try to build a generic abstraction stack between our different resources (CPU, RAM, disk, etc.) and our services (Chat, Storage, etc.):

ansible (physical node conf)
nomad (schedule containers)
consul (distributed key value store / lock / service discovery)
garage/glusterfs (file storage)
stolon + postgresql (distributed relational database)
docker (container tool)
bottin (LDAP server, auth)

Some services we provide:

Chat (Matrix/Riot)
Email (Postfix/Dovecot/Sogo)
Storage (Seafile)

As a generic abstraction is provided, deploying new services should be easy.

I am lost, how this repo works?

To ease the development, we make the choice of a fully integrated environment

os the base os for the cluster 1. build: where you will build our OS image based on Debian that you will install on your server 2. config: our Ansible recipes to configure and update your freshly installed server
apps apps we deploy on the cluster 1. build: our Docker files to build immutable images of our applications 2. integration: Our Docker compose files to test locally how our built images interact together 3. config: Files containing application configurations to be deployed on Consul Key Value Store 4. deployment: Files containing application definitions to be deployed on Nomad Scheduler
op_guide: Guides to explain you operations you can do cluster wide (like configuring postgres)

Clone the repository

git clone https://gitlab.com/superboum/deuxfleurs.fr.git
git submodule init
git submodule update

Deploying/Updating new services is done from your machine

The following instructions are provided for ops that already have access to the servers.

Deploy Nomad on your machine:

export NOMAD_VER=0.9.1
wget https://releases.hashicorp.com/nomad/${NOMAD_VER}/nomad_${NOMAD_VER}_linux_amd64.zip
unzip nomad_${NOMAD_VER}_linux_amd64.zip
sudo mv nomad /usr/local/bin
rm nomad_${NOMAD_VER}_linux_amd64.zip

Deploy Consul on your machine:

export CONSUL_VER=1.5.1
wget https://releases.hashicorp.com/consul/${CONSUL_VER}/consul_${CONSUL_VER}_linux_amd64.zip
unzip consul_${CONSUL_VER}_linux_amd64.zip
sudo mv consul /usr/local/bin
rm consul_${CONSUL_VER}_linux_amd64.zip

Create an alias (and put it in your .bashrc) to bind APIs on your machine:

alias bind_df="ssh \
  -p110 \
  -N \
  -L 4646:127.0.0.1:4646 \
  -L 8500:127.0.0.1:8500 \
  -L 8082:traefik.service.2.cluster.deuxfleurs.fr:8082 \
  <a server from the cluster>"

and run:

bind_df
