**OBSOLETION NOTICE:** We are progressively migrating our stack to NixOS, to replace Ansible. Most of the files present in this repository are outdated or obsolete,
|
||||
the current code for our infrastructure is at: <https://git.deuxfleurs.fr/Deuxfleurs/nixcfg>.
|
||||
|
||||
## 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/):** S3-compatible lightweight object store for self-hosted geo-distributed deployments (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)
|
||||
* **[guichet](https://git.deuxfleurs.fr/Deuxfleurs/guichet):** a dashboard for our users and administrators
|
||||
* **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.

3. `op_guide`: Guides to explain you operations you can do cluster wide (like configuring postgres)
|

|
||||
|
||||
## Start hacking
|
||||
|
||||
### Deploying/Updating new services is done from your machine
|
||||
|
||||
*The following instructions are provided for ops that already have access to the servers (meaning: their SSH public key is known by the cluster).*
|
||||
|
||||
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 1389:bottin2.service.2.cluster.deuxfleurs.fr:389 \
|
||||
-L 4646:127.0.0.1:4646 \
|
||||
-L 5432:psql-proxy.service.2.cluster.deuxfleurs.fr:5432 \
|
||||
-L 8082:traefik-admin.service.2.cluster.deuxfleurs.fr:8082 \
|
||||
-L 8500:127.0.0.1:8500 \
|
||||
<a server from the cluster>"
|
||||
```
|
||||
|
||||
and run:
|
||||
|
||||
bind_df
|
||||
|
||||
Adrien uses `.ssh/config` configuration instead. I works basically the same. Here it goes:
|
||||
|
||||
```
|
||||
# in ~/.ssh/config
|
||||
|
||||
Host deuxfleurs
|
||||
User adrien
|
||||
Hostname deuxfleurs.fr
|
||||
# If you don't use the default ~/.ssh/id_rsa to connect to Deuxfleurs
|
||||
IdentityFile <some_key_path>
|
||||
PubKeyAuthentication yes
|
||||
ForwardAgent No
|
||||
LocalForward 1389 bottin2.service.2.cluster.deuxfleurs.fr:389
|
||||
LocalForward 4646 127.0.0.1:4646
|
||||
LocalForward 5432 psql-proxy.service.2.cluster.deuxfleurs.fr:5432
|
||||
LocalForward 8082 traefik-admin.service.2.cluster.deuxfleurs.fr:8082
|
||||
LocalForward 8500 127.0.0.1:8500
|
||||
```
|
||||
|
||||
Now, to connect, do the following:
|
||||
|
||||
ssh deuxfleurs -N
|
||||
|
||||
## Test cluster
|
||||
|
||||
Configured machines available for testing are listed in the **[`test_cluster` Ansible inventory](./os/config/test_cluster.inventory.yml)**.
