Three docker components: Image and docker1. Images of Docker's three major components. A corresponding image must exist locally before Docker runs the container. If the image does not exist locally, Docker downloads the image from the image repository (default isDocker Hub Public Registry server warehouse ).Obtain images from the repository, manage images on the

Three major docker components: container and docker1. containers are another core concept of Docker. Simply put, containers are one or more applications that run independently and Their runtime environments. The virtual machine can be understood as a simulation.A complete set of operating systems (including the running environment and other system environments) and applications running on them.1.1 start con

A few days ago encountered such a business scenario, the database runs in the Docker, the Docker city is UTC so it is 8 hours away from the Beijing time.

Very distressed, First I change the host's time zone to CST Beijing

Preface Under normal circumstances, if our computer in a networked environment, we can directly through the Docker pull images to obtain the relevant image, of course, this must be a networked environment, depending on the user's network speed or the size of the image has a different wait, If we were able to build a mirror repository like remote networking locally, and put our usual images in our own managed repositories, wouldn't it be possible to qu

of three Docker1 mirroringImage, is a read-only template, similar to the ISO file used by the installation system, we use mirroring to complete the deployment of various applications. A mirror can contain only one operating system environment (such as the SuSE image), or the user program and its operating environment (such as a ebackup mirror) can be installed. A mirror is actually a file, and any user program can be part of the image.Mirroring = Operating system + software operating environmen
