Hi,
Learning Dockers and it’s given --link is a legacy now (Legacy container links | Docker Docs) when this will be removed and we’ll learn the new technology?
–link is legacy but has not yet been removed. There is no information on when it will be removed.
Docker has replaced the --link flag with networks, enabling containers to communicate directly using DNS-based service discovery.
You can read more here:
Networking overview | Docker Docs
The --link flag is a legacy feature of Docker. It may eventually be removed. Unless you absolutely need to continue using it, we recommend that you use user-defined networks to facilitate communication between two containers instead of using --link .
If I’m not remembering wrong a good reason to use docker and not Kubernetes is because docker by default enable the dns server to facilitate communication between containers, in Kubernetes is a bit more complex, but you can modify the dns and the load balancer as you like. If I’m not wrong the “user-defined networks” is very straight foward to use in docker, is like you almost don’t need to touch it (If I’m not wrong, I never use docker swarm, but I get the idea and know a little). So maybe you don’t need to worry to much about the “new technology” because in many cases you are already using it.
So long story short:
Docker: Hi I’m ready to go or almost, please don’t try to change the config files unless you really know what are you doing.
Kubernetes: Here are some objects, have some fun and create something usefull.
Hope this helps you @altugozgercek
