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

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

In the previous section we deployed ETCD, and this section installs and configures flannel. Build Flannel Flannel do not have a ready-made executable file available, you must build it yourself, the most reliable way is to build in the Docker container.

Docker learning: configure the rancher network environment, download and start the Tomcat container1. About rancher The rancher environment was set up last time, but the network was not configured properly (). Container not created successfully. This time, it turns out to be a network problem. The coreos installed in virtualbox is not configured with an ip address, causing network access failure. The agent

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

Link modehttp://blog.csdn.net/halcyonbaby/article/details/42112325The container is created by link, and then we can access it using the alias of the link container.This will remove the application's reliance on the IP.Unfortunately, the link method only solves the interconnection between single-machine containers. In multi-machine cases, the interconnection of containers requires other means.[[emailprotected] ~]#
