So I have been using docker with docker-compose for quite some time in a development environment, I love how easy it is.
Until now, I also used docker-compose to serve my apps on my own server as I could afford short down times like docker-compose restart.
But in my current project, we need rolling updates.
We still have one node, and it shall remain as we don't plan on having scalability issue for quite some time.
I read I need to use docker swarm, fine, but when I look for some tutorials on how to set it up, along with using my docker-compose.yml files, I can't find any developer-oriented (instead of devops) resources that would simply tell me the steps to achieve this, even though I don't understand everything it is ok, as I will along the way.
Are there any tutorials to learn how to set this up out there? If not, shouldn't we build it here?
I am definitely sure we are quite numerous to have the issue, as docker is now a must have for devs, but we (devs) still don't want to dive too deep into the devops world.
Cheers, hope it gets attention instead of criticism.
