- docker run: This command is used to create and start a new container. For example, to run a container using the official Nginx image, you can use the following command:
- docker start: This command is used to start a stopped container. For example, to start a container named “mynginx”, you can use the following command:
- docker stop: This command is used to stop a running container. For example, to stop a container named “mynginx”, you can use the following command:
- docker rm: This command is used to remove a stopped container. For example, to remove a container named “mynginx”, you can use the following command:
- docker pull: This command is used to download a Docker image from a registry. For example, to download the official Nginx image, you can use the following command:
- docker images: This command is used to list all the Docker images on your system. For example, to list all the images on your system, you can use the following command:
- docker rmi: This command is used to remove a Docker image. For example, to remove the Nginx image, you can use the following command:
- docker volume create: This command is used to create a new Docker volume. For example, to create a new volume named “myvolume”, you can use the following command:
- docker volume ls: This command is used to list all the Docker volumes on your system. For example, to list all the volumes on your system, you can use the following command:
- docker volume rm: This command is used to remove a Docker volume. For example, to remove a volume named “myvolume”, you can use the following command:
- docker network create: This command is used to create a new Docker network. For example, to create a new network named “mynetwork”, you can use the following command:
- docker network ls: This command is used to list all the Docker networks on your system. For example, to list all the networks on your system, you can use the following command:
- docker network rm: This command is used to remove a Docker network. For example, to remove a network named “mynetwork”, you can use the following command:
- What is Docker Compose? Docker Compose is a tool for defining and running multi-container Docker applications. It allows you to define all the services that make up your application in a single file, and then spin them up with a single command.
- Why use Docker Compose? Docker Compose can save you time and effort by automating the process of creating and managing multiple containers. It’s especially useful for applications that require multiple services, such as a web application that needs a web server, a database, and a caching layer.
- How to use Docker Compose: To get started with Docker Compose, you’ll need to install it on your Windows system. Once you’ve done that, you can create a `docker-compose.yml` file in the root directory of your application, which defines all the services that make up your application. Here’s an example `docker-compose.yml` file for a simple web application:
- To start your application, run the following command in the same directory as your `docker-compose.yml` file:
- What is Docker Swarm? Docker Swarm is a container orchestration tool that allows you to manage multiple Docker hosts as a single system. It’s built into the Docker Engine, so you don’t need to install any additional software.
- Why use Docker Swarm? Docker Swarm can help you manage complex applications that require multiple containers running across multiple hosts. It provides features such as service discovery, load balancing, and rolling updates, which can save you time and effort when managing large-scale applications.
- How to use Docker Swarm: To get started with Docker Swarm, you’ll need to initialize a Swarm on one of your Docker hosts. Once you’ve done that, you can use the `docker service` command to create and manage services across your Swarm. Here’s an example of how to create a simple service using Docker Swarm:
- This command creates a new service named `my-service`, with 3 replicas, and publishes it on port 8080. The `nginx` image is used as the base for the service.
- What is Docker Machine? Docker Machine is a tool for provisioning and managing Docker hosts on various cloud providers and virtualization platforms.
- Why use Docker Machine? Docker Machine can save you time and effort by automating the process of creating and managing Docker hosts. It’s especially useful for developers who need to test their applications on multiple platforms or cloud providers.
- How to use Docker Machine: To get started with Docker Machine, you’ll need to install it on your Windows system. Once you’ve done that, you can use the `docker-machine` command to create and manage Docker hosts. Here’s an example of how to create a new Docker host on Amazon Web Services:
- This command creates a new Docker host on Amazon Web Services, with the name `my-aws-host`. You can then use the `docker-machine env` command to set the environment variables for your new host, and start using Docker as usual.
- Use SSDs for Docker Images: Docker images can be large, and reading and writing to them can be slow if you’re using a traditional hard drive. Consider using an SSD for storing your Docker images to improve performance.
- Limit Container Resources: If you’re running multiple containers on the same host, you may want to limit the resources that each container can use. This can help prevent any one container from hogging all the system resources and causing performance issues for other containers.
- Use Docker’s Built-in Caching: Docker’s built-in caching can help improve performance by reducing the amount of time it takes to build and run containers. Make sure you’re taking advantage of this feature by using Docker’s caching commands, such as `docker build –no-cache`.
