Make board servers properly periodically re-register themselves with the relay #24

Closed RussellJoyce closed 4 years ago

RussellJoyce commented 4 years ago

Sometimes board servers seem to disappear from the relay and not come back without restarting their containers (although this needs properly testing to determine whether it's a persistent problem).

The relay might remove a board because it can't SSH ping the board server (or for some other reason), but the board should be re-registered automatically by https://github.com/RTSYork/VLAB/blob/master/boardserver/register.py in a cronjob. This might have bugs, or possibly there are other issues causing this.

This is potentially just down to times when the board server container cannot resolve the relay server, e.g. when using mDNS.

I think with the changes made in 874f9f4 (and other recent improvements) this issue has probably gone away now, so closing it with the plan that it can be re-opened if we observe this behaviour again.
