docker psI have previously deployed two tomcats in docker, one is port 8088, the other is port 8089, and entered the two containers to write simple pages Access port 8088
Now access the contents of two tomcats through nginx to achieve the load balancing function. Due to the difference, it can better reflect the load balancing function. The content of the two pages is different, but the access paths are the same, just reverse through nginx The proxy goes to rotate access
