Create ansible and manage container nodes based on DockerScenario: When learning conditions are limited, you can complete Docker and ansible learning with a single VMFIX: Create a custom image and build multiple ansible containers first.Of course, this method is suitable for other similar scenarios.VMS Environment:
Os:centos7docker version 1.12.3, build 6b644ecdocker-compose version 1.8.1, build 87

With the stack YAML file defined, the application can be deployed through the Docker stack deploy command.
Docker will create the various resources according to the YAML content. In order to not duplicate the name, all resources will be prefixed with the stack names, and we are here wpstack_*.
After deployment is complete, you can view the status of various resources throug
Today, a test bug was submitted by a tester during a system integration test because the time of submitting business data was biased against the actual time (Beijing time), resulting in statistical anomalies. Since our integration test is a test environment that provides the tester with a complete Docker mirror directly, the reason should be on the container time setting.

In order to advance the technology and the operational efficiency of the work, the author introduced the Docker container deployment mode, through the Gitlab+jenkins+harb

Start a mirror that has been configured for JDK, Tomcat, named Tomcat01.
Use Route-n to view the route of the host, ifconfig to view the host's IP.
DOCKER0 network card is docker when the installation is started on the
syntax and commands, and you can refer to Docker's official documentation.
2. With the Dockerfile file, you can create image files based on Dockerfile, and in the directory where Dockerfile is located, run the following command
sudo docker build-t centos6-ssh.
When the command succeeds, an image named Centos6-ssh is created and can be viewed using the sudo docker images.
3. At this point, you can creat

Preface
Everyone uses Docker to download images from the container repository, but this process may depend on the bandwidth of the network, so if you migrate a downloaded image to another environment, or how to implement a backup or restore of a docker container, or migrate, let's talk about it a bit.
----------------
To support container Cross host communication, Docker provides overlay driver, allowing users to create overlay networks based on Vxlan. Vxlan can encapsulate two-tier data into UDP for transmission, Vxlan provides the same Ethernet two-tier service as the VLAN, but with greater scalability and flexibility. More detailed information about Vxlan can be referenced in the relevant chapters of Cloudman's 5-minu
Kubernetes is Google's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purp

Service assumptions within the PAAs platform are deployed within the Docker container, so to meet non-functional requirements, another process is responsible for collecting logs, thus not intruding into service frameworks and processes. Using flume ng for log collection,
Some students have installed nginx under Docker but do not know where the directory is, you can use the command" 50x.html "Because Nginx is bound to have 50x.html, so look for it, the results found Nginx directory in the Docker container, if you operate it, you need to enter the container shell.The
As we all know, Docker run can specify port mappings, but once the container is generated, no command can be modified directly. Typically, the indirect approach is to save the image, create a new container, and specify a new port mapping at the time of creation.
Is there any way to modify the existing container withou
