docker instance

Preface We have mentioned earlier that if we build the Docker cluster, there will be the need for a Docker instance network connection across the host, and in order to save the IP resources of the host network, we try to use DOCKER0 own network connection, add Host network IP to the main node (container instance), This

Introduced inside Docker The image is running on the filesystem and the parameters are that it will never change. The container is an instance of the mirror runtime. when you're in Docker When you run a command on it, he runs the following actions:1. Check if the image exists2. if not, download3. Load the image run the action you wantView Local containers[[email

Today in the start of a Docker run Nginx instance, when the directory is mounted, access to the static directory, insufficient permissions The commands executed are: Docker run --name my-nginx -d-p 80:80 --restart=always -v/cloud/nginx/webroot:/usr/share/nginx/ HTML:RW -v/cloud/nginx/log:/var/log/nginx -v/cloud/nginx/config/nginx.conf:/etc/nginx/nginx.con

strategies. We have implemented continuous integration (CI) through Docker and Jenkins. The project in Git, if a git push occurs, triggers the Jenkins job to build automatically, and if the build succeeds, it generates Docker image and push to the mirrored warehouse. Based on CI-generated Docker Image, a PAAs API or interface can be used to develop an

Docker manually configure the container network The network of the Docker container is a combination of the net namespace and the virtual device, which creates a pair of virtual interfaces Veth pair at startup, which are placed in the local and container respectively, The local Veth is assigned a name similar to the vethxxxx and is bridged to the specified network bridge (default is Docker0) and can be vie

The reason is that the security module in CentOS7 selinux the permissions, at least in the following three ways to solve the problem of a mounted directory without permissions: 1, when running the contain

): -- cidfile ='' Docker containers have no privileges. For example, you cannot start another container in the container. This is because the container cannot access any other device by default, but through "privileged ", the container has the permission to access any other device. ========================================== Instance Root @ ip-10-249-100-205 ~] # Yum install

While Docker is still primarily based on the Linux platform, Microsoft has repeatedly announced support for Docker, from p

LS look at the current list of services, and you can see a service called Tomcat. Running Docker Service PS Tomcat can see which swarm node the Tomcat services are running on, and the status of the currently running. Switch to the node where the Tomcat service runs, and run Docker PS to see the container ID and the port mapping. Run the Docker logs-f containe

logs-f container ID to view the Tomcat run log. After Tomcat startup is successful, you can access the Tomcat home page in the browser, which is the IP of the Docker node (which can be any node), and the port is 9090, the publish specified when the service is created. The top has successfully run a Tomcat service, which extends the deployment of this service. Run the Docker service scale tomcat=2 to ext
