Why use configuration management over dockerfiles and images?
- nailer 5y agoOrchestration is more than just configuring individual instances, but rather being able to deploy your entire app which may include instances, load balancers, lambdas, data stores and/or other infrastructure.
- edmcnulty101 5y agoNo I mean why use Ansible and Puppet when you can create clean workloads from a docker image.
- exdsq 5y agoThey said they’re using VMs over Docker for better security control
- edmcnulty101 5y agoAh gotcha. Thanks. Missed that.
- deivid 5y agoyou can still export a container and run it as a vm with a bit of effort: https://blog.davidv.dev/docker-based-images-on-baremetal.html https://blog.davidv.dev/docker-based-images-on-baremetal.htm...
- exdsq 5y agoInteresting! I haven't used VMs in a while due to being fully sucked into the world of Docker, but isn't VM configuration at the point you can do something similar to a Dockerfile to run? Or is it easier to go from Dockerfile -> VM?
- mrweasel 5y agoWe use Ansible to configure and deploy containers in many cases. Dockerfiles and container images aren’t really doing the same thing as configuration management.
