One of the most frequently encountered problems in learning Docker recently is that, when downloading Docker image, because of a well-known network failure, there are many solutions on the web, such as the use of a domestic mirroring service like the Docker Hub Mirror, But for personal reasons (lucky to have a foreign

Dockerfile content, because all operations must be performed based on Dockerfile. Then, the command in Dockfile is executed one by one. Each step creates a new container, executes commands in the container, and submits modifications (just like docker commit ). After all the commands are executed, the final image id is returned. All containers generated by the intermediate steps are deleted and cleared. * N

I recently am playing with Docker, an application container and a virtual technology for Linux. It is so cool that it takes only a few minutes to create a Docker image and container. All work is out-of-the-box. Before I finish my day's work, I hope to save my work. But I am messy between the

A running image is called a container. You can modify the container (such as deleting a file), but these changes do not affect the image. However, you can use the Docker commit command to turn a running container into a new image. The Export command is used to persist the container (not mirroring). Therefore, we need t

These two days put the alarm platform in the Docker inside ran, but the host itself performance is not good, so cause MongoDB to hang several times. This time had a good server, although opentstack inside the host, but the IOPS is very nice. It is convenient to migrate the program inside the Docker, as before, it requires redeploying the environment and static files. Put in

This is enough to demonstrate the great benefits of mirror multiplexing.SummarizeWhile learning Docker, there are often three

Basic concepts: Container Container. Each container can be viewed as a standalone host. The creation of container usually has an image as its template. Analogy to a virtual machine can be understood as image is the mirror of the virtual machine, and container is a running virtual machine. A virtual machine image can create multiple running virtual h
