*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.), we develop our own tools when needed:
|
|
|
|
* **[garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/):** object storage (we also have a legacy glusterfs cluster)
|
|
* **[diplonat](https://git.deuxfleurs.fr/Deuxfleurs/diplonat):** network automation (firewalling, upnp igd)
|
|
* **[bottin](https://git.deuxfleurs.fr/Deuxfleurs/bottin):** authentication and authorization (LDAP protocol, consul backend)
|
|
* **ansible:** physical node configuration
|
|
* **nomad:** schedule containers and handle their lifecycle
|
|
* **consul:** distributed key value store + lock + service discovery
|
|
* **stolon + postgresql:** distributed relational database
|
|
* **docker:** package, distribute and isolate applications
|
|
|
|
Some services we provide:
|
|
|
|
* **Websites:** garage (static) + fediverse blog (plume)
|
|
* **Chat:** Synapse + Element Web (Matrix protocol)
|
|
* **Email:** Postfix SMTP + Dovecot IMAP + opendkim DKIM + Sogo webmail (legacy) | Alps webmail (experimental)
|
|
* **Storage:** Seafile (legacy) | Nextcloud (experimental)
|
|
* **Visio:** Jitsi
|
|
|
|
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
|
|
|
|
1. `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
|
|
2. `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
|
|
3. `op_guide`: Guides to explain you operations you can do cluster wide (like configuring postgres)
|
|
|

### 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
|
|
export NOMAD_VER=1.0.1
|
|
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:
|
|
|
|
```bash
|
|
export CONSUL_VER=1.9.0
|
|
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-admin.service.2.cluster.deuxfleurs.fr:8082 \
|
|
-L 5432:psql-proxy.service.2.cluster.deuxfleurs.fr:5432 \
|
|
-L 1389:bottin2.service.2.cluster.deuxfleurs.fr:389 \
|
|
<a server from the cluster>"
|
|
```
|
|
|
|
and run:
|
|
|
|
```
|
|
bind_df
|
|
```
