The nodejs request interface on the container docker server reports error: getaddrinfo ENOTFOUND xxx.xxxx.com xxx.xxxx.com:443.

Reason:

The current server cannot be connected to the request you want to request.

Solution:

1. Ping xxx.xxxx.com on the current server to see if it can be pinged (If the ping fails, it is a proxy problem, add xxxx xxx.xxxx.com in the hosts file.)
2. If it can be pinged, use the curl command to request the path to see if it can be called
3. If you are using the ip path interface, the call may be unsuccessful or the default port is not opened (80 is the default port of http, 443 is https)
4. If it can be pinged and the interface can be successfully called by using the curl command on the server, but it cannot be called in the project, it may be that the hosts file has been modified but did not take effect. Solution for this situation: add hosts in the container or inherit the hosts when starting the container (inherit hosts: when starting the docker container, add a sentence $(cat /etc/hosts|awk -F ”'{if(NR>2 ){print “–add-host “$2”:”$1}}’), you can integrate the host’s hosts file)

docker run --restart=always $(cat /etc/hosts|awk -F ' ' '{if(NR>2){print "--add-host "$2":"$1}}') -d -p 主机端口:容器端口 --name 指定容器名字 仓库/容器
