Title: Re: How can I get a PV from an external server from inside a docker container?
Hello Dale, hello Florian,
many thanks for your helpful advises. Now I could solve the issue simply by adding "network_mode: host" to the service "epicsbase".
Now my working docker-compose.yml looks like:
services: epicsbase: image: softioc container_name: epicsbase volumes: - ./epicsbase/db:/usr/local/db working_dir: /usr/local/epics command: - /bin/sh - -c - | echo start first Soft IOC screen -d -m /usr/local/epics/epics-base/bin/linux-x86_64/softIoc -D /usr/local/epics/epics-base/dbd/softIoc.dbd -d /usr/local/db/test.db tail -f /dev/null # keep alive
network_mode: host
Best regards Carsten

Hello,
I have 3 SoftIOCs. 1.) local host = 193.100.100.100 with PV: "local_pv" 2.) external host = 192.200.200.200 with PV: "external_pv" 3.) docker container on local host with PV: "docker_pv"
From local host I can read all PVs (caget local_pv external_pv docker_pv). 👍 From inside the docker container I can read the local_pv and the docker_pv but not the external_pv. 🤔
Here is my docker compose configuration:
services: epicsbase: image: softioc container_name: epicsbase volumes: - ./epicsbase/db:/usr/local/db working_dir: /usr/local/epics command: - /bin/sh - -c - | echo start first Soft IOC screen -d -m /usr/local/epics/epics-base/bin/linux-x86_64/softIoc -D /usr/local/epics/epics-base/dbd/softIoc.dbd -d /usr/local/db/test.db tail -f /dev/null # keep alive networks: - ioc-net networks: ioc-net:
From inside the docker container I have also already tried EPICS_CA_AUTO_ADDR_LIST / EPICS_CA_ADDR_LIST. Unfortunately without success. With and without these environment variables I only get the local_pv and the docker_pv.
How can I also read the external_pv from inside the docker container?
Best regards Carsten
