docker-compose up -d
Visit you browser at <docker-ip.:8080. See a hash that represents the hostname of the one PHP-FPM app server that is running through the load balancer.
docker-compose scale php=2
Now visit your browser again at the same address and reload the page a few times. You will see that the hash changes. There are now two nodes running that are load balanced.
- Make HAProxy HA
- Add logging (elk)
- add logging agents (logspout)
- Add monitoring (bosun/prometheus)
- add monitoring agents (cAdvisor?)
- Configure php-fpm pool for cpu and memory contraints, static: all are always running for maximum responiveness and utilization of the container
- Set resource limits on containers in docker-compose.yml
- Add ping/pong check between php-fpm and HAproxy.
