# Docker
Docker is a platform that simplifies the creation, deployment, and running of applications using containers.
### Docker commands
- build an image
```
docker build -t image-name .
```
- To run a docker image to crate a container.
```
docker run image_name
```
- To run a docker image to crate a container in detached mode (in the background).
```
docker run -d image_name
```
- To do port mapping and runnig container (To access application running inside container port 8080 from
our local machine port 5000. By default app inside container cannot talk with outside world)
```
docker run -p 5000:8080 image-name
```
or
```
docker run -p 5000:8080 -d image-name
```
- Stop a running container
```
docker stop
```
eg:- docker stop container_name
- List all local Docker images
```
docker images
```
- List all running containers
```
docker ps
```
- To see all the containers(even the stopped containers)
```
docker ps -a
```
or
```
docker ps -a
```
- Remove one or more containers
```
docker rm container_id
```
- To remove containers forcely
```
docker rm container_id -f
```
- Remove one or more images
```
docker rmi
```
eg:- docker rmi image_id
- Pull an image or a repository from a registry like dockerHub
```
docker pull
```
eg:- docker pull ubuntu:latest
- To Run a command in a running container
```
docker exec -it container_name command
```
eg:- docker exec -it container_name bash
we can use bash or sh or ash
- To list all volume
```
docker volume ls
```
- To remove one or more volumes
```
docker volume rm volume_name
```
- To remove all unused volume
```
docker volume prune
```
# Docker compose
Docker Compose is a tool that simplifies the management of multi-container Docker applications through a single YAML configuration file.
### Docker compose commands
- Build or rebuild services defined in the docker-compose.yml file
```
docker-compose build
```
- List the containers managed by a Docker Compose project
```
docker-compose ps
```
- To starts and orchestrates all containers defined in the Docker Compose configuration file
```
docker-compose up
```
- To rebuild the images and starts all containers defined in the Docker Compose configuration file.
```
docker compose up --build
```
We can also do it in detach mode using -d
```
docker compose up -d --build
```
- To stops and removes all containers, networks, volumes, and images created by 'docker-compose up'
```
docker-compose down
```
- To shut down the Docker containers defined in a Docker Compose file and remove associated volumes
```
docker-compose down -v
```
- To creates or rebuilds Docker images defined in the docker-compose.yml file
```
docker-compose build
```
- To Start existing containers for a service
```
docker-compose start
```
- TO Stop running containers without removing them
```
docker-compose stop
```
- To restarts containers defined in the Docker Compose configuration file
```
docker-compose restart
```
- To Run a command in a running container
```
docker-compose exec
```
eg:- docker-compose exec service_name command
- To view output from containers
```
docker-compose logs
```
=======================================================================================
- Command to up or down in development mode
```
docker compose -f docker-compose.yaml -f docker-compose.dev.yaml up -d
```
```
docker compose -f docker-compose.yaml -f docker-compose.dev.yaml down -v
```
-v deletes anonymous volumes
- Command to up or down in production mode
```
docker compose -f docker-compose.yaml -f docker-compose.prod.yaml up -d --build
```
```
docker compose -f docker-compose.yaml -f docker-compose.prod.yaml down -v
```
# REDIS
commands
```
docker exec -it 83f7dda4732c sh
```
```
redis-cli
```
```
PING
```
```
KEYS *
```
```
GET key_name
