So far, we have seen how powerful Docker is but we have not unleashed the full potential of containers. You have learned how to run containers on a single host with the local resources without the possibility of clustering our hardware resources in a way that allows us to uniformly use them as one big host. This has a lot of benefits, but the most obvious one is that we provide a middleware between developers and ops engineers that acts as a common language so that we don't need to go to the ops team and ask them for a machine of a given size. we just provide the definition of our service and the Docker clustering technology will take care of it.
In this chapter, we are going to dive deep into deploying and managing applications on Kubernetes, but we will also take a look at how Docker Swarm works.
People usually tend to see Kubernetes and Docker Swarm as competitors, but in my experience, they solve different problems:
- Kubernetes...
