=============
*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)
2020-09-12 08:03:48 +00:00
* garage/glusterfs (file storage)
2019-06-01 14:02:49 +00:00
* 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
2020-09-12 18:17:07 +00:00
1. `os` the base os for the cluster
2020-09-12 18:18:41 +00:00
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
2020-09-12 18:17:07 +00:00
2. `apps` apps we deploy on the cluster
2020-09-12 18:18:41 +00:00
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
2020-09-12 18:17:07 +00:00
3. `op_guide` : Guides to explain you operations you can do cluster wide (like configuring postgres)

## Start hacking
### 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:
```bash
2020-12-22 09:46:26 +00:00
export NOMAD_VER=1.0.1
2019-06-01 14:02:49 +00:00
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:
```bash
2020-12-22 09:46:26 +00:00
export CONSUL_VER=1.9.0
2019-06-01 14:02:49 +00:00
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 \
2020-09-21 14:29:49 +00:00
-L 5432:psql-proxy.service.2.cluster.deuxfleurs.fr:5432 \
2019-06-01 14:02:49 +00:00
< a server from the cluster > "
```
and run:
```
bind_df
```
