docker container security

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

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. After you get the delivered

ObjectiveThe company has been using the traditional Tomcat to drop the war package architecture system, with the increase of the project, the number of servers, the need to spend a lot of time on different server system environment issues. 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

Introduction Container technology has radically changed the way that applications, are, being developed and deployed. Notably, containers dramatically ease dependency management, so shipping new features or the code is faster than the ever. While Docker containers and kubernetes are great for DevOps, they also present new security challenges Practitioners and de

Update Docker containerAfter installing Redmine with Docker, it's been a long time, and in the days of maintaining the server, the Redmine version was also upgraded.Just think about upgrading the container, too.First, the general idea: Upgrade Docker Image Close 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

ObjectiveUsually in the Docker experiment, you will often need to modify some configuration parameters, some parameters modified, it is necessary to restart the Docker background process daemon to take effect, but after the Docker daemon restarts, may cause the running container to force shutdown. This is inconvenient

This series of Docker learning is CENTOS7 under the study. 1. Container Host/Host Access container 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

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.
