docker-learning's Introduction

Learning Docker from the basics!

This repository will be updated with my progress into the Container's World!

Useful commands (used so far)

docker ps
- shows running containers;
docker ps -a
- shows all containers;
docker images
- shows all images (running and stopped);
docker tag [imageID] [giveItAName]
- naming an already built image;
docker tag [imageID] [giveItAName]:[butAlsoATag]
- giving an already existing image a name and a tag;
docker build [PATH]
- if the Dockerfile with your image settings is located in the same path you are, you can use . , else use a path;
docker build -t [giveItAName] [PATH]
- Flag -t (tag) lets you name your image when you are building it;
docker build -t [giveItAName]:[butAlsoATag] [PATH]
- you can not just name it while building it, but also TAG it;
docker run [image]
- creates and starts a new container;
docker run -d [image]
- flag -d (detached) runs a new container without holding the terminal;
docker run -p [imagePORT:appPORT] [image]
- flag -p (port) specifies the port the container will be running. You access localhost:imagePORT and it uses the port you made available in your app;
docker run -d -p [imagePORT:appPORT] [image]
- a combination of the two last commands. It runs an image on a new container on specific port with a free terminal;
docker run -d -p [imagePORT:appPORT] --name [giveItAName] [image]
- you can give a name to your container when creating it. Names should be unique, as IDs;
docker stop [container]
- used to stop the specific container running, use container's ID or its name to stop it;
docker start [container]
- after stopping a container, you can always start it again;
docker start -i [container]
- You can always see your logs or interactively pass commands on the terminal with your --interactive flag;
