Docker cheat sheet

Simple setting to dealing with Dockerfile and docker-compose

Install Docker

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    Lsb-release

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io

Basic Docker Commands

1. how to search a docker image in hub.docker.com

docker search httpd

2. Download a docker image from hub.docker.com

docker image pull <image_name>:<image_version/tag>

3. Show all docker images on your local system

docker image

4. Build docker image from Dockerfile

docker build -t <image_name> . #the dot in the end specify the current directory where the Dockerfile is located 

5. Create a docker container from image

docker run --name <container_Name> <image_name>:<image_version/tag>

docker - run your container in back ground (detached)
 
docker run -d --name <container_Name> <image_name>:<image_version/tag>

6. Expose your application to host server

docker run -d --name <container_Name> -p <host_port>:<container_port> <image_name>:<Image_version/tag>

docker run -d --name httpd_container -p 8080:80 httpd:latest

7. Show all running containers

docker ps

8. Show all docker container (running, stpooed, terminated, etc...)

docker ps -a

9. Get inside a container

docker exec -it <container_Name> bash

10. Stop a container

docker stop <container_id>

11. Start a container which is stopped

docker start <container_id>

12. Remove a container

docker rm <container_id>

13. Remove docker image

docker rmi <image_id>

Dockerfile

Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

Docker compose

Docker compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application's services. Then, with a single command, you create and start all the services from your configuration.
