Docker
Docker is a platform for developing, shipping, and running applications.
Introduction to Containers
Containers are lightweight, portable, and self-sufficient units that can run applications.
Installation ubuntu
Install Docker on your Ubuntu system to get started with containerization.
Docker Architecture
Docker architecture consists of the Docker daemon, Docker client, and Docker images.
Docker Images
Docker images are read-only templates used to create containers.
docker build -t myapp .
Docker Containers
Docker containers are instances of Docker images that can be run and managed.
Docker Commands
Common Docker commands include docker run, docker build, and docker ps.
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
docker infochecks the Docker installation and provides information about the Docker environment.
Client:
Server:
docker run hello-world runs a test container to verify
docker create creates a new container from an image.
docker version checks the Docker version.
docker images lists all Docker images on your system.
docker images pull fedora pulls the Fedora image from the Docker Hub.
docker images ls lists all Docker images on your system.
docker container ls lists all running Docker containers.
docker container ls --all lists all Docker containers on your system.
docker container create -it fedora bash creates a new container from the Fedora image.
docker container start -i starts a stopped container in interactive mode.
docker container stop stops a running container.
docker container rm removes a stopped container.
docker container run runs a new container from an image. pull et start
Docker Compose
Docker Compose is a tool for defining and running multi-container Docker applications.
Docker Networking
Docker networking allows containers to communicate with each other and with the outside world.
Docker Volumes
Docker volumes are used to persist data generated by and used by Docker containers.
Docker Security
Docker security involves best practices for securing Docker containers and images.
Conclusion
Docker simplifies application deployment and management, making it easier to build, ship, and run applications in any environment.
