Docker is a newborn thing, and the concept is similar to virtualization. There are a lot of things about Docker getting started online. However, this paper discusses the characteristics, characteristics and principles of Docker, also introduces the installation test process with Chinese characteristics, and also talks about the community ecology and dockerfile of

Use Docker to deploy Gitlab and docker to deploy gitlab
The company's code server has been built using Gitosis, but it is too troublesome to manage users and permissions,Now we want to build Gitlab on the original server and install it directly using the official Gitlab method,This will cause a conflict with Gitosis, making Gitosis unavailable,To keep the two services at the same time, we thought of using
port 80 on the respective container.
User namespaces
Starting with Linux 2.6.23 completed on Linux 3.8)
User and group ID spaces
The user and group IDs of the processes in user namespace can be different from the host, and each container can have a different user and group ID, and a non-privileged user on a host can be a privileged user in the user namespace ;
The concept of Linux namespace is simple, simple and complex. Simply put, we just need to know tha

In front of our lab environment, only one Docker host container is running on this host. However, in a real environment, there will be multiple host containers that start, run, stop, and destroy related containers in these hosts, regardless of whether they are located in the same host.How can we manage such a multi-host environment efficiently?The first problem we faced was installing and configuring Docker
1. BackgroundAgile development has been popular for a long time, and now more and more enterprises are beginning to practice agile development advocated by people-centric, iterative, progressive development concept. The first goal of introducing Docker technology in this scenario is to use the virtualization provided by Docker to create a reusable development environment for the development team, allowing t

Docker network modes and docker network Modes
When using docker run to create a Docker container, you can use the -- net option to specify the container network mode. Docker has the following four network modes:

First, don't forget the two previous questions:1. How do I save our changes in the container?2. How do I install the software in Docker if the Apt-get is not installed?Remove Mirror commandBefore that, remember a command,sudo docker rm ID/NAMEThe image that was created is deleted.Now delete the mirror with id "cc8a23b1d624".sudo docker rm cc8a23b1d624As you can s
