Simple PHP Test Container
Can be used to demo serivce upgrades.
:latest/:7 tag uses PHP 7 Apache base image.
:5 tag is based on PHP 5.6 Apache base image.
Example for upgrade demo:
Using Docker 1.12 in Swarm mode:
docker service create --name phpdemo --publish 80:80 --replicas 10 toughiq/phptest:5
Now you have 10 instances running on Port 80.
Check: docker service ps phpemo
If you access the server and hit Reload, you should see different container IDs.
Now lets upgrade:
docker service update --update-delay 5s --image toughiq/phptest:7 phpdemo
We update our 10 instances to version 7. Interval between each container is 5 seconds. During this update you should see different versions of the app, if you hit reload in your browser.
