How To

Swarm mode

[bargee@node-01 ~]$ sudo /etc/init.d/docker restart v1.12.0-rc3
[bargee@node-01 ~]$ docker swarm init --listen-addr "<manager-ip-address>:2377"

You may need to specify --listen-addr "<manager-ip-address>:2377" in case of https://github.com/docker/docker/issues/23877#issuecomment-229224920 .

[bargee@node-02 ~]$ sudo /etc/init.d/docker restart v1.12.0-rc3
[bargee@node-02 ~]$ docker swarm join "<manager-ip-address>:2377"

[bargee@barge ~]$ sudo -i
[root@barge ~]# pkg install shadow
[root@barge ~]# echo "dockremap:100000:65536" > /etc/subuid
[root@barge ~]# echo "dockremap:100000:65536" > /etc/subgid
[root@barge ~]# echo 'DOCKER_EXTRA_ARGS="--userland-proxy=false --userns-remap=default"' >> /etc/default/docker
[root@barge ~]# /etc/init.d/docker restart v1.11.2

Set Timezone

[bargee@barge ~]$ date
Fri Jul  8 20:51:36 UTC 2016
[bargee@barge ~]$ sudo pkg install tzdata
[bargee@barge ~]$ echo 'Europe/Paris' | sudo tee /etc/timezone
Europe/Paris
[bargee@barge ~]$ sudo cp -L /usr/share/zoneinfo/Europe/Paris /etc/localtime
[bargee@barge ~]$ date
Fri Jul  8 22:51:58 CEST 2016

You can find your timezone at /usr/share/zoneinfo after installing tzdata package.

To set back to UTC,

[bargee@barge ~]$ echo 'Etc/UTC' | sudo tee /etc/timezone
Etc/UTC
[bargee@barge ~]$ sudo ln -sf /usr/share/zoneinfo/Etc/UTC /etc/localtime
[bargee@barge ~]$ date
Fri Jul  8 20:52:19 UTC 2016
