Thanks for explaing the concept in a short and simple. Can you make a video of docker-compose.yml file with managing secrets and replication in an isolated container with namespacing concept.

I have used Dockerfile to create a new image. Created a container and is running fine in one Server (ex. Serv-1).
I want to deploy the same running container on different server (Serv-2). Tried to do so, but it is throwing an error in Serv-2 that docker is not found. Install package.
My question is "Do we need to install docker package on every server where we want to run the container? Please clarify as Im in state of confusion.
