Add nginx.conf to Kubernetes cluster

You can create a ConfigMap object and then mount the values as files where you need them:

apiVersion: v1kind: ConfigMapmetadata:  name: nginx-configdata:  nginx.conf: |    your config    comes here    like this  other.conf: |    second file    contents

And in you pod spec:

spec:  containers:    - name: nginx      image: nginx      volumeMounts:        - name: nginx-config          mountPath: /etc/nginx/nginx.conf          subPath: nginx.conf        - name: other.conf          mountPath: /etc/nginx/other.conf          subPath: other.conf  volumes:    - name: nginx-config      configMap:        name: nginx-config

(Take note of the duplication of the filename in mountPath and using the exact same subPath; same as bind mounting files.)

For more information about ConfigMap see:https://kubernetes.io/docs/user-guide/configmap/

Note: A container using a ConfigMap as a subPath volume will not receive ConfigMap updates.

I haven't found a good way to escape the nginx configuration contents in the ConfigMap. The best recourse for me was to use ConfigMap creation using files

Save the following as ./data/nginx.conf

user  nginx;worker_processes  1;error_log  /var/log/nginx/error.log warn;pid        /var/run/nginx.pid;events {    worker_connections  1024;}http {    include       /etc/nginx/mime.types;    default_type  application/octet-stream;    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '                        '$status $body_bytes_sent "$http_referer" '                        '"$http_user_agent" "$http_x_forwarded_for"';    access_log  /var/log/nginx/access.log  main;    sendfile        on;    #tcp_nopush     on;    keepalive_timeout  65;    #gzip  on;    include /etc/nginx/conf.d/*.conf;}

Now create the configMapkubectl create configmap confnginx --from-file=./data/nginx.conf

Save the following deployment and pod yaml as nginx.yaml

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2kind: Deploymentmetadata:  name: nginx  labels:    app: nginx     spec:  selector:    matchLabels:      app: nginx  replicas: 1 # tells deployment to run 2 pods matching the template  template: # create pods using pod definition in this template    metadata:      # unlike pod-nginx.yaml, the name is not included in the meta data as a unique name is      # generated from the deployment name      labels:        app: nginx         spec:      containers:        - name: nginx          image: nginx:alpine          ports:          - containerPort: 80                  volumeMounts:            - name: nginx-config              mountPath: /etc/nginx/nginx.conf              subPath: nginx.conf      volumes:        - name: nginx-config          configMap:            name: confnginx

Now create it in k8kubectl apply -f nginx.yaml
