Getting started with Docker swarm The worst way to install swarm is to use the image on the Docker website. root@syx-vb:~# DAO Pull Swarm use the following command to see if the Swarm is installed successfully: root@syx-vb:~# Docker run--rm swarm-v swarm version 1.2.2 (34E3DA3) Use before using swarm to manage the cluster, you need to change the Docker daemon of all nodes in the cluster to 0.0

First, the discovery of problems Landlord regardless of input that command, have appeared: Ii. Solutions As well as similar errors, even the docker version command is an error, the landlord began looking for, found a lot of things, the results found that no one can do, the last landlord to use such a command: Add the following content to the file: That's all. I don't know what to do. It's really amazing. Landlord quickly used a bit

Gson is very powerful in parsing JSON data, but sometimes it is troublesome to use it improperly. 1 "cyclic serialization" Exception The solution is to add transient to fields that may cause loop serialization. Transient private menu parent; // parent node 2. Sort specific fields For example, if the JSON data of a user is {ID: "1", name: "syxchina", password: "syx"}, we do not want to parse the password during parsing, the format is {ID: "1", name
