Hi!
I’m pretty new to Docker and Rancher, but we’re currently growing our team (from 3 to 12 in the last 2 years!) and I’m starting to migrate towards Microservices and a dockerised dev environment.
I’ve come up with a pretty neat dev -> deployment procedure which can pretty much be summed up as follows:
Production environment:
- All 10 of the services have their images in our registry.
- There’s a
docker-compose.production.ymlwhich links all the images together into a deployable stack.
Rancher is great for deploying this 
So, the Development environment is:
- Setup a production environment
- Clone down the repo for the microservice you’re working on.
- That microservice contains it’s own
docker-compose.ymlwhich hasvolumes for the source code dirs. - Run
microservice$ docker-compose -f /path/to/docker-compose.production.yml -f docker-compose.yml up -d
Now our developer has 9/10 services running as per the production config, and one service running as per the development config. Great!
My problem is that if I deploy do the developer’s environment via rancher, I can see the rancher stack of containers running there all with the r_ prefix… But now should I integrate my dev container into the stack?
I’m imagining there may be a solution where I just bring up the dev container for that service, and tell Rancher to use that container instead of the existing one for that service…
I apologise if there’s a simple/obvious solution to this – or if I’m totally over-engineering this. As I said - new to docker. Still haven’t quite got my head around scaling and load-balancers etc…
I’d love to hear your suggestions!
Thanks,
Dean.
