Today, in the Docker, we are able to easily package our applications with containers and deploy them on our servers and run them. However, talking about how to stop the Docker container in the running and terminate the program correctly is a very worthwhile topic to discuss.
In fact, in our daily projects, this is a problem that we often have to confr
The container is the second core concept of Docker, and the simple one is that the container is a running instance of the mirror, and the difference is that it has an extra writable file layer. If the virtual machine is simulated running a full set of operating systems (providing a running state environment and other system environments) and running on the appli
, we first use Gson to deserialize it into a Java object, and then take the log field we care about to get the original log text, the next process is the same as the original.in.tell();String preReadLine = readSingleLine();ifnullreturnnull; //if the log is wrapped by docker log format, //should extract origin log firstly if (wrappedByDocker) { DockerLog dockerLog = GSON.fromJson(preReadLine,
in our when Docker container operation, sometimes misoperation or other reasons inadvertently quit the container in operation, you may worry that some of your operations have not been saved, there is no need to worry, this article will provide a variety of methods for your reference (my recommendation to use the last one). In this article, we will discuss five (4
The last section mentions that when the container is running, the data generated will not be in the write image, and re-starting the new container with this image will initialize the image and add a new read-write layer to hold the data. If you want to do data persistence, Docker provides data volume or data container
Adjust the partition size of Rootfs in Docker
The main introduction here is to adjust the size of the rootfs within the container, Rootfs the default is 10G, we can increase the size by the following method.bash-4.1# DF-LHTFileSystem Type Size Used avail use% mounted onRootfs rootfs 9.8G 1.4G 7.9G 15%/Tmpfs tmpfs 921M 0 921M 0%/devSHM tmpfs 64M 0 64M 0%/dev/shm/dev/vdb xfs 100G 2.1G 98G 3%/etc/resolv.conf/d

When you start using Docker, people often ask: "How do I get into the container?" "And others will say" run an SSH server in your container. " However, from this blog post you will learn that you do not need to run the sshd daemon to enter your container. Unless, of course, your co
In real life, a container is a thing to hold something. Put your application in the container, the environment in the container you can freely customize, you can install anything you need in the configuration application, and then you can take the container of the application and run it anywhere, where you don't need t

If you use Docker on CentOS, Rehl, Fedor, or other Linux distributions that do not have AUFS support by default, you may need to use Device Mapper's storage plug-in. By setting this plugin as the default, it will store all your containers in a short 100G file and limit the maximum of 10GB per
