 - for persistant volume you only need to map *data* folder
 - to run cronicle "as a service" use *restart=always* option
 - you may optionally use *--net=host* parameter if interacting with cronicle nodes on other machines (in this case don't use hostname parameter, it should be the same as your host)
+- you can specify secret_key via env variable. CRONICLE_manager=1 will start up cronicle right away (only use on single manager node/cluster)
