Recently I start to stady Kubernetes. Now I know how to deploy nginx in pod with default options, and I know how deply nginx with custom nginx.conf with configmap. Now I have a question if I want to use nginx with ftp. Ftp need to have access in directory where nginx.conf. It is possible ? Maybe someone know simple example ?
You could have your ftp container as a sidecar for the nginx main container and share the volume between the containers:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
labels:
app: nginx
spec:
selector:
matchLabels:
app: nginx
replicas: 1
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: <your nginx image>
ports:
- name: http
containerPort: 80
volumeMounts:
- name: config
mountPath: /etc/nginx/nginx.conf
subPath: nginx.conf
- name: ftp
image: <your ftp image>
ports:
- name: ftp
containerPort: 21
volumeMounts:
- name: config
readOnly: true
mountPath: /etc/nginx/nginx.conf
subPath: nginx.conf
volumes:
- name: config
configMap:
name: nginx-configand the service expose both ports
