      So I went to update my CentOS7 install on a Ramnode VPS. It would install correctly and then when starting the service it would error out, complaining about not being able to create a network bridge. The fix was to install lxc along with docker. So now I've got two container systems, uck.

      sudo yum -y install docker docker-selinux lxc

          Bother, got a big NOPE from it still.

          Jul 20 12:36:26 travisdh1 forward-journal[1831]: time="2016-07-20T12:36:26.706277656-04:00" level=warning msg="Your Linux kernel version 2.6.32-042stab113.11 can be unstable running docker. Please upgrade your kernel to 3.10.0."

          That's gonna be really, really, really difficult to do if you want to run CentOS/RedHat.

            I don't understand what Red Hat is doing here. They've kind of abandoned LXC in actual RHEL, you need EPEL. But they are pushing Docker really hard, and telling you to do things like use a shell session in the container and somehow porting SystemD into the container to allow multiple services. Why? Don't change Docker, just use LXC. Two different things.

              Man they're really holding you back too. My CentOS 7 VMs are at 3.10.0-327.22.2.el7.x86_64

                I'm guessing they don't give you a CentOS Atomic image to use either, just a full blown CentOS image?

                  Yep. I think they run their own repos, which while nice, won't fix problems with basic network configs.

                    Running their own repos is only nice is they mirror the real CentOS ones rather than being behind or different.

                      It's a VPS, so it'd be kinda difficult to keep me out of the normal repos. A local repo for popular distros just makes a lot of sense for a company offering that sort of service tho.

                          Linode, Digital Ocean and Vultr have great support that doesn't break things by "being weird" as many smaller vendors seem to do.

                            Yeah, I was using RamNode because they had a $5/month plan with 150GB storage. Nobody else even bothers to respond to me when I ask about a service using HDD anymore.

                              Vultr. We talk about using their SATA HDD service all of the time. It's the main reason that any of us use it.

                                I'm going to go ahead and contact them about it, since they don't have anything on the website 😕

                                  This comes up all the time too... you sign in and the details are all there. For some reason, their SATA offerings are not displayed until you log in.
