Ahoj,
nechci zbytečně rýpat, neznám bližší souvislosti, ale nody v Praze a Brně bych pokud možno upgradoval vždy zvlášť. Když už to má někdo jako failover apod., tak ať to má smysl. Co myslíte?
Jinak díky a dobrá práce! Docker 1.10 jsem tento týden taky testoval na playground bez použití KVM a až na pár warning hlášek (Seccomp is not enabled in your kernel; Your kernel does not support OOM notifications) bez problému.
