I create configmap with the command line kubectl like this:
kubectl create configmap nginx-config --from-file=./site.confIn my site.conf I have a simple nginx conf:
server {
listen 80;
index index.php index.html;
location / {
try_files $uri $uri/ /index.php?$args;
access_log off;
expires max;
}
}
In my nginx-pod.yaml I have normal pod setup:
apiVersion: v1
kind: Pod
metadata:
name: www
labels:
app: nginx
spec:
containers:
- name: proxy
image: nginx
ports:
- containerPort: 80
volumeMounts:
- mountPath: /etc/nginx/conf.d
name: nginx-config
volumes:
- name: nginx-config
configMap:
name: nginx-configWhen a start the pod like this:
kubectl create -f nginx-pod.yamlMy pod is create but his status CrashLoopBackOff 2-3 sec later but if I remove this line:
volumeMounts:
- mountPath: /etc/nginx/conf.d
name: nginx-config
volumes:
- name: nginx-config
configMap:
name: nginx-configI have no problems.
Something else is messing you out. I've just literally copied your conf and yaml file (except running it with -n test-namespace for separation) and it worked flawlessly.
Running ok, jumped to pod, and site.conf is happily mounted in /etc/nginx/conf.d folder as intended. Baremetal k8s version I'm using is 1.9.2 and configuration wise this is correct.
Edit: Just tried it with minikube on Mac as well (client 1.9.3 server 1.9.0) and it also just works (not even namespaces there, exactly your described steps).
Can you see logs for scheduler/api or pod in failed state? Maybe it can shed more light to what is preventing it from starting? You don't have RBAC misconfigured or something across namespaces that would prevent config map from being read?
I have had the seem ploblem recently in the problem was the site.conf. Your pod load your configmap correctly pour when nginx load her conf your nginx crash end your pod crash . Check your site.conf end add de default value like this
server {
listen 80;
listen [::]:80;
root /var/www/html/quickstart/public;
index index.php index.html index.htm index.nginx-debian.html;
server_name example.com www.example.com;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
}
