How to use it in the production environment?

[zjp24355]

There is no network in the production environment. How can it be used in the production environment?
Elasticsearch and kibana are 5.6.3
Request detailed steps, thank you!

no network at all or just no internet connection?

I don't know if we have a build for 5.6.3 and likely going below 6.2 will be hard for us.

no internet connection, only internal network.
there is also a 6.2.2 version of the cluster.
If 6.2.2 can be installed offline, please help. thank you!
