Build a image from Dockerfile:

docker build -t app-image:latest .

Export image to archive:

docker save -o backup.tar app-image:latest

Import image from archive:

docker load -i backup.tar

Run container with parameters:

docker run -d \\
  --name web-service \\
  -p 8080:80 \\
  -v /host/logs:/container/logs \\
  --net bridge \\
  --platform linux/amd64 \\
  app-image:latest

Network Configuration

Network modes:

• bridge: Isolated network stack (default)
• host: Shares host's network namespace
• none: Disables networking

Check image platform:

docker inspect --format '{{.Os}}/{{.Architecture}}' app-image:latest

Buildx Multi-Platform Tool

Initialize builder:

docker buildx create --name multiarch-builder
 docker buildx use multiarch-builder
 docker buildx inspect --bootstrap

Build and push multi-arch image:

docker buildx build \\
  -t registry/app-image:multi \\
  --platform linux/amd64,linux/arm64 \\
  --push .

Core Operations

• docker pull [repo/image]: Retrieve image
• docker push [repo/image]: Upload image
• docker images: List local images
• docker rmi [image]: Delete image
• docker run [options] [image]: Create container
• docker stop [container]: Halt container
• docker start [container]: Resume container
• docker restart [container]: Recycle container
• docker rm [container]: Remove container
• docker ps: Show active containers
• docker logs [container]: View output stream
• docker exec -it [container] sh: Access shell
• docker inspect [target]: Show metadata

Autostart configuration:

systemctl enable docker
docker update --restart unless-stopped [container]

Volume Commands

• docker volume create [name]: Provision storage
• docker volume ls: Enumerate volumes
• docker volume rm [volume]: Delete volume
• docker volume inspect [volume]: Show properties
• docker volume prune: Purge unused volumes

Network Commands

• docker network create [name]: Establish network
• docker network ls: List networks
• docker network rm [network]: Remove network
• docker network prune: Clean unused networks
• docker network connect [net] [container]: Attach container
• docker network disconnect [net] [container]: Detach container
• docker network inspect [network]: Show topology

Network example:

docker network create app-net
docker network connect app-net db-container --alias sql-db
docker network connect app-net api-container

Containers in custom networks communicate via aliases or names.
