Re: Phoebus is unable to see PVs inside docker containers

Hello Dhruv,

how is your org.phoebus.pv.ca/addr_list formated? It should be a list of IP's seperated by spaces. The observation you have
points to a problem here as it looks like your phoebus sees probably only the first host on that list.
You can check the settings that phoebus sees if you go "Help -> Abaut -> Show Details -> Preference Settings"

You could try to set EPICS_CAS_INTF_ADDR_LIST to be the address of the docker network interface before starting phoebus.
You need to kill caRepeater on the host before starting Poebus. Otherwise the change will not have any effect.

If that does not help, probably the easisest way to go is to implement a gateway on the Docker host. 

Hope this helps,

Jörn
