Agree 100%. Plus Helm runs against a basic tenet of microservices (the usual architecture for the deployed apps in k8s these days). People use to bundle services together when using Helm and the like which, in time, couples services together.
- dividedbyzero 4y agoBut don't you actually want a certain amount of coupling in the operations part? After all you need to ensure they run in a place and in a manner that allows them to find and talk to each other and usually in a combination determined by the goal of a specific deployment, i.e. sometimes you might not need a rail-cargo-service because the customer only ships by truck, etc. Then scaling/autoscaling (if any) needs to be compatible, versions need to be within a certain range, any central data store must be coordinated as well, not to speak of service meshes, chaos experiments and the like. It's a good thing to develop services with minimal coupling, but that stage has different risks and goals from devops/ops, at least in my experience on both sides of the dev/ops transition zone.
- mikedelago 4y ago> But don't you actually want a certain amount of coupling in the operations part? In my opinion, for sure. There's a balance between "too coupled" and "too de-coupled" that should be stricken rather than too far on either side. It's good to say that this is also contextual; some projects may be fine with either more or less coupling than others, and that's OK.
- thisiswrongggg 4y agoI understand but it is a slippery slope.
