Yaml is an intuitive data serialization format that can be read by a computer, easily readable by humans, and easy to interact with scripting languages. Yaml is similar to XML, but syntax is much simpler than XML and is very simple and efficient for converting data in an array or hash.

To start using your cluster, you need to run the following as a regular user:mkdir-p $HOME/.kube sudo cp-i/etc/kuber netes/admin.conf $HOME/.kube/config sudo chown $ (id-u): $ (id-g) $HOME/.kube/configyou should now deploy a pod network to The cluster. Run "Kubectl apply-f [Podnetwork].yaml" with one of the options listed At:https://kubernetes.io/docs/concepts/cluster-a Dministration/addons/you can now join all number of machines by ru

If you need a geographically redundant backup, the three pods must run in different zones.You can create such a redundant backup set with few changes. Each cluster needs its own Kubernetes YAML file to define pods, redundant controllers, and services. Then, you can complete cluster creation, persistent storage, and MongoDB nod

Kubernetes Cluster Deployment DNS ServiceIn Kubernetes each service will be assigned a virtual IP, each service under normal circumstances will not change for a long time, this is relative to the pod of the indefinite IP, the use of the cluster app is relatively stable.But the service's information injected into the pod is currently using an environment variable, and relies heavily on pod (RC) and service c

-slave configuration as needed.We use persistent volumes to prevent data in the database from being limited to any particular pods in the cluster. This prevents the database from losing data in the event that the MySQL host pod is lost, and when the host pod is lost, it can reconnect to the attached machine with xtrabackup and copy the data from the attached machine to the host. The replication of MySQL is responsible for host-secondary replication, while Xtrabackup is responsible for secondary-

1. What is YAML? Official website explanation %YAML 1.2---YAML: YAML Ain't Markup LanguageWhat It Is: YAML is a human friendly data serialization standard for all programming languages. 2.yaml syntax

Serialization in. NET is usually in binary or xml format. After ajax emerged, the JSON format is also used, which is rare compared with YAML. BinaryCannot be directly read. It must be decoded at the binary level;The format is defined by the vendor. When the objects to be represented by a specific application are complex, the format is also complex, such as the office file format;We usually need to fully consider the Protocol's scalability and compati

Although puppet is stable, it is very troublesome to configure the module during command execution, and you also need to install the client. If the company is in a cooperative relationship with other companies, obviously, installing the client is a factor that has to be considered; therefore, ansible is not inferior to the two tools in terms of performance and is not cumbers
