[@PR-zv4ur]

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.

[@SchoolofDevops]

Yup. You need Docker Daemon or equivalent (e.g. podman, containerd etc. ) installed on every node where you want to run containers on.

[@PR-zv4ur]

@@SchoolofDevops Thank you for the confirmation. By the way, I have gone through your videos. Amazing. Wonderful teacher you are....

[@nallavadlaganesh2726]

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.

[@SchoolofDevops]

ALl the featured that you mentioned are related to a Container Orchestration Enginer (COE) such as Kubernetes, and not Docker Compose.

[@nallavadlaganesh2726]

@@SchoolofDevops Ohh....!! My bad, Thanks for info #Gaurav. I will look in to that.
