Recently I started to study Kubernetes and right now I can deploy nginx with default options. But how I can deploy my nginx.conf in Kubernetes ? Maybe somebody have a simple example ?
Create yaml for nginx deployment:
kubectl run --image=nginx nginx -oyaml --dry-runapiVersion: apps/v1
kind: Deployment
metadata:
creationTimestamp: null
labels:
run: nginx
name: nginx
spec:
replicas: 1
selector:
matchLabels:
run: nginx
strategy: {}
template:
metadata:
creationTimestamp: null
labels:
run: nginx
spec:
containers:
- image: nginx
name: nginx
resources: {}
status: {}Create config ConfigMap with nginx configurtion
kubectl create configmap nginx-conf --from-file=./nginx.confMount file:
apiVersion: apps/v1
kind: Deployment
metadata:
creationTimestamp: null
labels:
run: nginx
name: nginx
spec:

selector:
matchLabels:
run: nginx
strategy: {}
template:

labels:
run: nginx
spec:
containers:
- image: nginx
name: nginx
resources: {}
volumeMounts:
- mountPath: /etc/nginx/nginx.conf
name: nginx-conf
subPath: nginx.conf
volumes:
- configMap:
name: nginx-conf
name: nginx-confYou can build your own image on top of nginx default image, then copy your own nginx.conf into that image. Once the image is created, you can push it to Dockerhub/your own private repository, and then use that image instead of the default nginx one in kubernetes.
This answer covers the process of creating a custom nginx image.
Once the image can be pulled into your kubernetes cluster you can deploy it to your cluster like so -kubectl run nginx --image=<your-docker-hub-username>/<customr-nginx>
