+Spawn container:
+
+```bash
+docker run -t -i superboum/arm32v7_postgres:v6
+# OR
+docker run -t -i superboum/amd64_postgres:v1
+```
+
+
+Init with:
+
+```
+stolonctl \
+ --cluster-name pissenlit \
+ --store-backend=consul \
+ --store-endpoints http://consul.service.2.cluster.deuxfleurs.fr:8500 \
+ init \
+ '{ "initMode": "new", "pgHBA": [ "host all postgres all md5", "host replication replicator all md5", "host all all all ldap ldapserver=bottin.service.2.cluster.deuxfleurs.fr ldapbasedn=\"ou=users,dc=deuxfleurs, dc=fr\" ldapbinddn=\"<bind_dn>\" ldapbindpasswd=\"<bind_pwd>\" ldapsearchattribute=\"cn\"" ] }'
+
+```
+
+Then set appropriate permission on host:
+
+```
+chown -R 102:102 /mnt/storage/postgres/
+```
+
+(102 is the id of the postgres user used in Docker)
+It might be improved by staying with root, then chmoding in an entrypoint and finally switching to user 102 before executing user's command.
+Moreover it would enable the usage of the user namespace that shift the UIDs.
+
+
+
+## Upgrading the cluster
+
+To retreive the current stolon config:
+
+```
+stolonctl spec --cluster-name pissenlit --store-backend consul --store-endpoints http://consul.service.2.cluster.deuxfleurs.fr:8500
+```
+
+The important part for the LDAP:
+
+```
+{
+ "pgHBA": [
+ "host all postgres all md5",
+ "host replication replicator all md5",
+ "host all all all ldap ldapserver=bottin.service.2.cluster.deuxfleurs.fr ldapbasedn=\"ou=users,dc=deuxfleurs,dc=fr\" ldapbinddn=\"cn=admin,dc=deuxfleurs,dc=fr\" ldapbindpasswd=\"<REDACTED>\" ldapsearchattribute=\"cn\""
+ ]
+}
+```
+
+Once a patch is writen:
+
+```
+stolonctl --cluster-name pissenlit --store-backend consul --store-endpoints http://consul.service.2.cluster.deuxfleurs.fr:8500 update --patch -f /tmp/patch.json
+```
