When I first started using Docker, I kept searching for the same commands over and over again.
Eventually, I realized that I only needed a handful of commands for 90% of my daily work.
Here are the four Docker commands I use the most.
1. Build an Image
docker build -t myapp:v1 .
This command creates a Docker image from your Dockerfile.
I always use version tags instead of latest because it makes deployments easier to track and roll back.
2. Run a Container
docker run -d -p 8080:8080 --name myapp_instance myapp:v1
What this does:
- Runs the container in the background
- Maps port 8080 on your machine to the container
- Gives the container a readable name
Instead of random container IDs, I can simply reference myapp_instance.
3. Monitor What's Happening
docker ps
Shows all running containers.
Need to inspect logs?
docker logs -f myapp_instance
The -f flag streams logs in real time, which is incredibly useful when debugging startup issues.
4. Stop and Remove Cleanly
docker stop myapp_instance && docker rm myapp_instance
One command.
No leftover containers.
No unnecessary clutter.
A Small Habit That Saves Time
I almost never use anonymous containers during development.
Naming containers makes debugging, logging, restarting, and scripting much easier.
It seems like a tiny habit, but it saves a surprising amount of time over the long run.
Quick Reference
docker build -t myapp:v1 .
docker run -d -p 8080:8080 --name myapp_instance myapp:v1
docker ps
docker logs -f myapp_instance
docker stop myapp_instance && docker rm myapp_instance
That's it.
You don't need to memorize dozens of Docker commands.
Master these four first, and you'll already handle most day-to-day Docker workflows with confidence.
If you found this useful, save it for later—you'll probably need these commands again.
