I'm trying to set some env vars on our DCOS/Mesos cluster - what's the simplest way to do that?

Can you explain what you want to achieve? Set global env vars for all spawned tasks? – janisz
@janisz . Yes, indeed – EugeneMi
The simplest way is to set them in /etc/environment or with init of Mesos Agent. If that's not an option you can manage your framework to do it or write mesos hook module that will inject env vars to the task. – janisz

I would suggest you taking a look at Consul and envconsul combo. Use Consul as K/V for storing and managing the variables across the cluster and envconsul to feed them to the apps inside the container. For secrets - add Vault. You have mentioned you were looking for simple solution. I would say it's relatively simple and elegant way to achieve that.
