What do cloud computing talents need to master? How to learn Docker containers well? Docker is a lightweight container management engine, which builds a bridge between software development and cloud computing platform, so cloud computing personnel must learn Docker container technology. Here are some basic Docker container operations and learning skills.

Common operations for Docker containers:

Docker exec-it container_name bash install Docker

Curl-sSL https://get.docker.com/ | boot is set for sh

Systemctl enable docker starts Docker

Systemctl start docker download image

Docker pull busybox (image_name:version) Delete Mirror

Upload image on docker rmi image_name:version

Docker logindocker push username/app creates a container

Docker run-d-p 5000 data/registry:/var/lib/registry registry:2 5000-- restart=always-- name registry-m 128m-v / simple version

Docker run-d-p 5000 5000-- name app nginx:1.11.1 changes the tag of the mirror

Some operations of docker tag nginx your_name/nginx on containers

Docker inspect app | grep-I memory (matching memory information here) create an image from the container

Docker save app > app.tar restore the image from the tar package

Docker load < app.tar sharing data between containers

Based on a number of open source technologies on the Linux platform, Docker provides efficient, agile and lightweight container solutions and supports deployment to local environments and a variety of mainstream cloud platforms. It can be said that Docker provides a "one-stop" practical solution for the development, operation and deployment of applications for the first time. So how to learn Docker quickly? You can refer to the following methods:

First of all, you need to understand the basic theoretical knowledge, start with a simple command line, understand Docker networks, understand how to create Docker clusters and use choreography systems, and master basic Docker concepts and tools; then you need to try to develop based on Docker, and be sure to ask questions if you encounter any problems in the process. If you feel that your self-control or learning ability is poor, it is best to participate in professional study, so that you can not only learn theoretical knowledge quickly, but also accumulate more project experience and kill many birds with one stone.
