ok. So we got this working. A few things required.
- Setup the proxy with authentication using raspi-config in the advanced settings. Set all proxies to http://userid:passwd@proxyip:port
Also setup NTP to use an internal NTP server. (update the timesyncd.conf file)
Then we run the screenly base install with
bash <(curl -sL https://install-ose.srly.io)
This should get docker installed but it wont finish due to proxy.
So after a reboot, setup the docker proxy settings using your link above (adding the same setting for proxy as above)
Then we can get docker to install/update the screenly with
./screenly/bin/upgrade_containers.sh
A final reboot should see it working.
Hope that helps someone else.
Thanks for your help nicomiguelino
