Here's what we're using which I'm pretty happy with:
0. Self-hosted Gitlab and Gitlab CI.
1. Chef. I'd hardly mention it because it's use is so minimal but we have it setup for our base images for the nitpicky stuff like connecting to LDAP/AD.
2. Terraform for setting up base resources (network, storage, allocating infrastructure VMs for Grafana).
3. Kubernetes. We use a bare minimum of manually maintained configuration files; basically only for the long-lived services hosted in cluster plus the resources they need (ie: databases + persistent volumes), ACL configuration.
4. Spinnaker for managing deployments into Kubernetes. It really simplifies a lot of the day-to-day headaches; we have it poll our Gitlab container repository and deploy automatically when new containers are available. Works tremendously well and is super responsive.
