API reference

Good resource

Juts a bunch of great examples

Docker images

docker images & docker image ls

Docker containers

docker ps -a & docker ps

docker start <container_id|container_name>

docker rm <container_id|container_name>

docker stop <container_id|container_name>

remove all stopped containers docker container prune

docker run -it --rm <container> (remove after usage) ex: docker run -it --rm nginx bash or docker run -it --rm nginx /bin/sh or docker exec -it <container_id|container_name> bash (-it stands for "interactive terminal") when it's running or docker exec -it <container_id|container_name> sh

docker logs <container_id|container_name>

docker run -d <container> run in background (detached)

docker run -d --name <some_name> <container> run in background (detached) input name

docker container inspect <container_id|container_name>

docker run -d -p 8080:80 <container> ex: docker run -d -p 8080:80 nginx

docker run -v ${PWD}:/usr/share/nginx/html -p 8080:80 -d --rm <container>

(env vars, options...) docker run --env POSTGRES_HOST_AUTH_METHOD=trust -ti --rm -d --name postgres-cn -p 8080:5432 postgres:10.10

Docker networks

docker networks docker network ls

create a network docker network create <network_name>

Ex

docker network create mongo-network

docker run -p 27017:27017 -d --network mongo-network --name mongodb-cn -e MONGO_INITDB_ROOT_USERNAME=modex98 -e MONGO_INITDB_ROOT_PASSWORD=password mongo

docker run --network mongo-network -e ME_CONFIG_MONGODB_SERVER=mongodb-cn -e ME_CONFIG_MONGODB_ADMINPASSWORD=password -e ME_CONFIG_MONGODB_ADMINUSERNAME=modex98 -p 8081:8081 --name mongodb-express-cn -d mongo-express

since both containers are in same network they can communicate using just container_name

Docker compose

docker-compose up -d (default file name is docker-compose.yaml)

docker-compose down

docker-compose -f <docker_compose_file_name> up -d

docker-compose -f <docker_compose_file_name> down

docker-compose up -d --build (when changes happen in the app)

Docker DockerFile

create an image docker build -f DockerFile . -t <image_name>:<image_tag>

Ex

docker build -f DockerFile . -t my_app:latest

docker run -d --name my_app-cn -p 3000:3000 my_app:latest

in the host volumes are located in /var/lib/docker/volumes
