Question 1

How do I install Docker on Ubuntu Server in 2025?

Accepted Answer

In my setup I install Docker straight from Ubuntu’s repository because it’s quick and reliable for a clean server build. I run an update/upgrade first, then install docker.io and enable the service so it starts automatically. After that, I confirm it’s working by checking the Docker version.

Question 2

How do I install Docker Compose on Ubuntu Server (Compose v2)?

Accepted Answer

I install Docker Compose using the Docker Compose v2 plugin package on Ubuntu. That gives me the modern `docker compose` command and makes running multi-container apps from one YAML file simple. Once it’s installed, I verify it by checking the Compose version.

Question 3

How do I set a static IP during Ubuntu Server installation?

Accepted Answer

During the network step, I choose manual configuration and enter the subnet in CIDR format, then the server’s IP address, gateway, and DNS. In my example I use a /24 network, my router as the gateway, and public DNS like 8.8.8.8 and 1.1.1.1. You can also use your router or a local DNS server if that’s how your network is set up.

Question 4

Why do you use MobaXterm instead of PuTTY for SSH?

Accepted Answer

I use MobaXterm because it gives me more control and it’s comfortable for installation work. The big win is the side-by-side view: file browser on the left and terminal on the right. That makes it easy to move around files while I run commands and troubleshoot.

Question 5

How do I install Portainer on Ubuntu with Docker?

Accepted Answer

I create a persistent Docker volume for Portainer first so the configuration stays safe. Then I run the Portainer CE LTS container, publish ports 8000 and 9443, mount the Docker socket, and attach the volume. After that I open the browser on https://<server-ip>:9443, create the admin user, and select the local Docker environment.

Question 6

What are Portainer Stacks and how do I deploy a docker-compose.yml?

Accepted Answer

Stacks in Portainer let me deploy a full application from a Docker Compose YAML without memorizing a bunch of commands. I go to Stacks, add a new stack, paste the YAML, include an environment file if needed, and hit deploy. Portainer builds the containers, networks, and volumes exactly as defined.

Question 7

Should I install snap packages like Docker runtime during Ubuntu Server setup?

Accepted Answer

Ubuntu offers snap packages during installation, and they can be convenient because they’re pre-built and easy to maintain. In this demo I skip snaps because I want a clean, controlled setup and I’m installing Docker myself afterward. For quick starts in small environments, snaps can still be useful.
