Database connection problem in ezmaster

[dieubenit]

Hello,

I am trying to deploy ezmaster your solution to create several lodex intances, as described in the document Installing Lodex with ezMaster - LODEX (inist.fr).

I am facing the problem of connection with the mongodb database.

Some pictures of my configurations.

Error [MongoError]: failed to connect to server [undefined:27017] on first connect [Error: getaddrinfo EAI_AGAIN undefined
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:66:26) {
name: 'MongoError'
}]

instances deployed in ezmaster :
`Long name Technical name Creation date Size Application Status Actions

base lodex-database-2 21 hours ago 319 MB inistcnrs/ezmaster-mongo:1.0.7

Parameter of connection to the instance :
"mongo": { "host": "lodex-database-2:27017" }
Thank you in advance for your help with the mongodb database connection.
