• Hot reloading configuration: why and how?

Prerequisites

Run

Ignition

cd sozu-docker-demo
docker-compose up

It could be lonf, so ... ☕️ or ☕️

Play

Now you should have 7 virtual machines:

webapp1         172.20.0.11:8080
webapp2         172.20.0.12:8080
webapp3         172.20.0.13:8080
webapp_new1     172.20.0.21:8080
webapp_new2     172.20.0.22:8080
webapp_new3     172.20.0.23:8080
sozuapp         172.20.0.00:8080

• the containers 1, 2 and 3 contain an Express web application (the same, but with a name generated at run time)
• the containers 4, 5 and 6 contain the version 2 of the Express web application
• the last VM contains the Sōzu reverse proxy
  • the ip of Sōzu is 172.20.0.99 and listen on 8080
  • I added this in my hosts file 172.20.0.99 sozu.local
  • then now, you'll connect to it with http://sozu.local:8080/

Remove application(s)

docker exec sozudockerdemo_sozu_1 /sozuctl --config /demo/demo.toml backend remove --id webapp --ip 172.20.0.11 --port 8080
docker exec sozudockerdemo_sozu_1 /sozuctl --config /demo/demo.toml backend remove --id webapp --ip 172.20.0.12 --port 8080
docker exec sozudockerdemo_sozu_1 /sozuctl --config /demo/demo.toml backend remove --id webapp --ip 172.20.0.12 --port 8080

Add application(s)

docker exec sozudockerdemo_sozu_1 /sozuctl --config /demo/demo.toml backend add --id webapp --ip 172.20.0.21 --port 8080
docker exec sozudockerdemo_sozu_1 /sozuctl --config /demo/demo.toml backend add --id webapp --ip 172.20.0.22 --port 8080
docker exec sozudockerdemo_sozu_1 /sozuctl --config /demo/demo.toml backend add --id webapp --ip 172.20.0.23 --port 8080
