gitops-example-dev

This repository illustrates the repository file format supported by the tool being developed in https://github.com/rhd-gitops-example/services. It represents the deployment configuration for one or more microservices (also known as 'components') for a 'dev' environment. Microservices are aggregated into applications under the 'apps' directory.

See our companion repository https://github.com/rhd-gitops-example/gitops-example-staging which represents a second environment from which services are 'promoted' to, from this 'dev' environment.

Environment-specific configuration is held in the /overlays directories, and may be applied at the level of a single service, an application, or the entire environment.

To see things working:

kustomize build environments/dev/services/service-a
kustomize build environments/dev/apps/app-1
kustomize build environments

or kubectl apply -k these paths

namespace considerations

The Kubernetes namespace that a repository in this format would be deployed in would typically be defined in a namespace.yaml file in env/base/.

The recommended best practice for deploying an individual app or service into a different namespace would be to:

1. Create the namespace.

kubectl create namespace my_namespace

2. Clone the GitOps repo.

git clone https://github.com/rhd-gitops-example/gitops-example-dev

3. Apply the app or service you want to your namespace.

kustomize build services/service-a | kubectl apply -n my_namespace -f -
kustomize build apps/app-a | kubectl apply -n my_namespace -f -
