+
+    network=$(cat all.json| jq -r '."cef694f3-081d-11e9-b31f-0242ec186adf".resources.eldiron."hetzner.networkInfo"' | jq -r -c '.networking.interfaces.eth0 = { "ipv4": { "addresses": [ { "address": .networking.interfaces.eth0.ipAddress, "prefixLength": .networking.interfaces.eth0.prefixLength } ] } }')

+
