Our Telescope App work well now in production. We run Telescope App on docker and Mongodb docker container used replicaset and oplog. NGInx managed all websites.
All worked smoothly. Thank You so much Sacha for your guideline and advise.
Now we start to make the localize version of our Telescope App (using a sub-domain for each local site): French, German, Chinese, Vietnamese.
I wonder if there are a way to have all users in a common users collections (mean each user should be able to sign-in to the English site but also to all localized sites) and User who sign-up on a localize site should be able to log-in to all sites.
Thank You Kosona
