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.

Nicmene, uz jsem rozplanoval prvni davku update na 1.3. 1:00, po
dni/dvou, podle toho, jak to pojede, budou nasledovat dalsi. Cili do cca
14ti dni by mohlo byt aktualizovano vsude.

Hello from Docker.
This message shows that your installation appears to be working
correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the
Docker Hub.
3. The Docker daemon created a new container from that image
which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client,
which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container
with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker Hub
account:
