🐋 Development with Docker

Steps to build a Docker Image.

Build

docker image build -t <IMAGE_NAME> -f <PATH_DOCKERFILE> <PATH_CONTEXT_DOCKERFILE>
docker image build -t <IMAGE_NAME> . (This context)

Run

Steps to run a Docker Container.

• Linux running:

docker container run -d -p <LOCAL_PORT:CONTAINER_PORT> <IMAGE_NAME> <COMMAND>
docker container run -it --rm --name <CONTAINER_NAME> -p <LOCAL_PORT:CONTAINER_PORT> <IMAGE_NAME> <COMMAND>

• Windows running:

winpty docker.exe container run -it --rm <IMAGE_NAME> <COMMAND>

For more information, access the Docker documentation or this.

🐋 Development with Docker Compose

Build and run a docker-compose.
