Replace your Swarm Manager and Workers with updated versions of docker

• it's best to replace nodes, don't do apt/yum upgrades.
• both would work, but VM replacment forces me to think of it as immutable and prevents making pets
• if you don't want to update join scripts for manager IP's, then do something like Elastic IP's so manager IP's won't change.

Lets assume you have 3 managers and 3 workers on 17.06 and you want to update to 17.12

• managers: m1, m2, m3

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead
