Dear HAProxy folks,
I am using a Docker setup to serve Web application using a database.
HAProxy, the Web app and the database each run in a separate Docker
container.
The HAProxy container is than started with the command below.
docker run --detach --name haproxy --link webapp:webapp myimages/haproxy
The goal is to have zero downtime deployments.
Now the problem is, that each time the Web app container is replaced by
a container run from a newer version, the HAProxy container has to be
stopped an started again so that the link works. This is certainly not
desired.
I search the Web for documentation and how-tos but couldn’t find
anything directly related to my issue. Do you know of such write-ups,
which I might have missed due to the generic key words.
Do you have any experiences with serving Web apps with HAProxy using
Docker links?
Should I stop using that “technology” and do things differently?
Thanks,
Paul
