-------------------------------
we pushed the images to dockerhub, then used docker-compose to deploy to the cluster
we mounted data volumes on these nodes
and linked app container here
finally we've updated the DNS records
hitler: so we're running 20 containers on every node now. when can we get rid of the excess servers?
mein fuhrer...
the kernel...
A 3rd party container caused a panic...
we've lost 70% of the cluster and the data volumes
.... hitler loses his shit ....
hitler: if you never used docker in production, leave the room now
hitler: isolation my ass!
hitler: what were you thinking?
hitler: who the hell uses public containers from docker hub?
hitler: for all you know they were made by russian hackers!
hitler: you might as well use `curl | sudo bash`
hitler: you think everything in public rpeo is secure because it's OSS?
hitler: you're a bunch of node.js hipsters that just HAVE to install everything you read on hacker news!
but docker allows us to run our applications anywhere!
hitler: you use a VM just to run docker on your laptop!
mein fuhrer, docker-machine uses a lightweight VM!
hitler: do you hear yourself? why do we need docker if we're running a VM?
hitler: a container inside a container!!!
hitler: you archived a whole linux O/S then used CoW storage becaues it's too big
hitler: Just so you can deploy a 10MB go Binary!
hitler: Dont even talk to me about resource constraints
hitler: all that cgroups black magic and it still can't stop a simple fork bomb!
hitler: and if the database needs all the resources on the server, how exactly will docker allow you to run more programs on it?
hitler: before docker, I just picked the right size VMs.
hitler: Suddenly people talk to me about datacenter efficiency and "hyperconvergence"
hitler: everybody thinkst they're google!
hitler: you don't even run your own machines anymore!
hitler: people run docker on GCE, in VM instances that run in linux containers on Borg!
hitler: people even think docker is configuration management
hitler: they think docker solves everything!
hitler: even microsoft has containers now
hitler: i'm moving everyone to windows!
dont cry, you can run bash on windows 10 now
hitler: docker is supposed to have better performance
hitler: yet that fucker userland proxy is slower than a 28.8k modem
hitler: and for what
hitler: just bind on port 0
hitler: even enterprises want to run docker now and they still have red hat 5 installed
hitler: you idiots think docker will help your application scale
hitler: use openstack for all I care
